The Free Translation Project +is a way to get maintainers of free software, translators, and users all +together, so that will gradually become able to speak many languages. +A few packages already provide translations for their messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work at translations should contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +Quick configuration advice +========================== + + If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in the +operating system where this package is being installed. So far, only +the `gettext' implementation in the GNU C library version 2 provides as +many features (such as locale alias, message inheritance, automatic +charset conversion or plural form handling) as the implementation here. +It is also not possible to offer this additional functionality on top +of a `catgets' implementation. Future versions of GNU `gettext' will +very likely convey even more functionality. So it might be a good idea +to change to GNU `gettext' as soon as possible. + + So you need _not_ provide this option if you are using GNU libc 2 or +you have installed a recent copy of the GNU gettext package with the +included `libintl'. + +INSTALL Matters +=============== + + Some packages are "localizable" when properly installed; the +programs they contain can be made to speak your own native language. +Most such packages use GNU `gettext'. Other packages have their own +ways to internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. If not, the GNU `gettext' own +library will be used. This library is wholly contained within this +package, usually in the `intl/' subdirectory, so prior installation of +the GNU `gettext' package is _not_ required. Installers may use +special options at configuration time for changing the default +behaviour. The commands: + + ./configure --with-included-gettext + ./configure --disable-nls + +will respectively bypass any pre-existing `gettext' to use the +internationalizing routines provided within this package, or else, +_totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might be not what is desirable. You +should use the more recent version of the GNU `gettext' library. I.e. +if the file `intl/VERSION' shows that the library which comes with this +package is more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + The configuration process will not test for the `catgets' function +and therefore it will not be used. The reason is that even an +emulation of `gettext' on top of `catgets' could not provide all the +extensions of the GNU `gettext' library. + + Internationalized packages have usually many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +Using This Package +================== + + As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, +and `CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your country by running the command +`locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +Translating Teams +================= + + For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" +area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `translation@iro.umontreal.ca' to reach the +coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skill are praised more than +programming skill, here. + +Available Packages +================== + + Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of May 2003. +The matrix shows, in regard of each package, for which languages PO +files have been submitted to translation

It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. (Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have to compile the package for one architecture at a +time in the source code directory. After you have installed the +package for one architecture, use `make distclean' before reconfiguring +for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). Here is a another example: + + /bin/bash ./configure CONFIG_SHELL=/bin/bash + +Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent +configuration-related scripts to be executed by `/bin/bash'. + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 000000000000..5bad6071e80e --- /dev/null +++ b/Makefile.am @@ -0,0 +1,208 @@ +# This file is part of flex. + +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: + +# 1.

The description is +in the form of pairs of regular expressions and C code, called "rules". +`flex' generates as output a C source file, `lex.yy.c' by default, +which defines a routine `yylex()'. This file can be compiled and +linked with the flex runtime library to produce an executable. When +the executable is run, it analyzes its input for occurrences of the +regular expressions. Whenever it finds one, it executes the +corresponding C code. + + +File: flex.info, Node: Simple Examples, Next: Format, Prev: Introduction, Up: Top + +4 Some Simple Examples +********************** + +First some simple examples to get the flavor of how one uses `flex'. + + The following `flex' input specifies a scanner which, when it +encounters the string `username' will replace it with the user's login +name: + + + %% + username printf( "%s", getlogin() ); + + By default, any text not matched by a `flex' scanner is copied to +the output, so the net effect of this scanner is to copy its input file +to its output with each occurrence of `username' expanded. In this +input, there is just one rule. `username' is the "pattern" and the +`printf' is the "action". The `%%' symbol marks the beginning of the +rules. + + Here's another simple example: + + + int num_lines = 0, num_chars = 0; + + %% + \n ++num_lines; ++num_chars; + . ++num_chars; + + %% + main() + { + yylex(); + printf( "# of lines = %d, # of chars = %d\n", + num_lines, num_chars ); + } + + This scanner counts the number of characters and the number of lines +in its input. It produces no output other than the final report on the +character and line counts. The first line declares two globals, +`num_lines' and `num_chars', which are accessible both inside `yylex()' +and in the `main()' routine declared after the second `%%'. There are +two rules, one which matches a newline (`\n') and increments both the +line count and the character count, and one which matches any character +other than a newline (indicated by the `.' regular expression). + + A somewhat more complicated example: + + + /* scanner for a toy Pascal-like language */ + + %{ + /* need this for the call to atof() below */ + #include math.h> + %} + + DIGIT [0-9] + ID [a-z][a-z0-9]* + + %% + + {DIGIT}+ { + printf( "An integer: %s (%d)\n", yytext, + atoi( yytext ) ); + } + + {DIGIT}+"."{DIGIT}* { + printf( "A float: %s (%g)\n", yytext, + atof( yytext ) ); + } + + if|then|begin|end|procedure|function { + printf( "A keyword: %s\n", yytext ); + } + + {ID} printf( "An identifier: %s\n", yytext ); + + "+"|"-"|"*"|"/" printf( "An operator: %s\n", yytext ); + + "{"[\^{}}\n]*"}" /* eat up one-line comments */ + + [ \t\n]+ /* eat up whitespace */ + + . printf( "Unrecognized character: %s\n", yytext ); + + %% + + main( argc, argv ) + int argc; + char **argv; + { + ++argv, --argc; /* skip over program name */ + if ( argc > 0 ) + yyin = fopen( argv[0], "r" ); + else + yyin = stdin; + + yylex(); + } + + This is the beginnings of a simple scanner for a language like +Pascal. It identifies different types of "tokens" and reports on what +it has seen. + + The details of this example will be explained in the following +sections. + + +File: flex.info, Node: Format, Next: Patterns, Prev: Simple Examples, Up: Top + +5 Format of the Input File +************************** + +The `flex' input file consists of three sections, separated by a line +containing only `%%'. + + + definitions + %% + rules + %% + user code + +* Menu: + +* Definitions Section:: +* Rules Section:: +* User Code Section:: +* Comments in the Input:: + + +File: flex.info, Node: Definitions Section, Next: Rules Section, Prev: Format, Up: Format + +5.1 Format of the Definitions Section +===================================== + +The "definitions section" contains declarations of simple "name" +definitions to simplify the scanner specification, and declarations of +"start conditions", which are explained in a later section. + + Name definitions have the form: + + + name definition + + The `name' is a word beginning with a letter or an underscore (`_') +followed by zero or more letters, digits, `_', or `-' (dash). The +definition is taken to begin at the first non-whitespace character +following the name and continuing to the end of the line. The +definition can subsequently be referred to using `{name}', which will +expand to `(definition)'. For example, + + + DIGIT [0-9] + ID [a-z][a-z0-9]* + + Defines `DIGIT' to be a regular expression which matches a single +digit, and `ID' to be a regular expression which matches a letter +followed by zero-or-more letters-or-digits. A subsequent reference to + + + {DIGIT}+"."{DIGIT}* + + is identical to + + + ([0-9])+"."([0-9])* + + and matches one-or-more digits followed by a `.' followed by +zero-or-more digits. + + An unindented comment (i.e., a line beginning with `/*') is copied +verbatim to the output up to the next `*/'. + + Any _indented_ text or text enclosed in `%{' and `%}' is also copied +verbatim to the output (with the %{ and %} symbols removed). The %{ +and %} symbols must appear unindented on lines by themselves. + + A `%top' block is similar to a `%{' ... `%}' block, except that the +code in a `%top' block is relocated to the _top_ of the generated file, +before any flex definitions (1). The `%top' block is useful when you +want certain preprocessor macros to be defined or certain files to be +included before the generated code. The single characters, `{' and +`}' are used to delimit the `%top' block, as show in the example below: + + + %top{ + /* This code goes at the "top" of the generated file. */ + #include + #include + } + + Multiple `%top' blocks are allowed, and their order is preserved. + + ---------- Footnotes ---------- + + (1) Actually, `yyIN_HEADER' is defined before the `%top' block. + + +File: flex.info, Node: Rules Section, Next: User Code Section, Prev: Definitions Section, Up: Format + +5.2 Format of the Rules Section +=============================== + +The "rules" section of the `flex' input contains a series of rules of +the form: + + + pattern action + + where the pattern must be unindented and the action must begin on +the same line. *Note Patterns::, for a further description of patterns +and actions. + + In the rules section, any indented or %{ %} enclosed text appearing +before the first rule may be used to declare variables which are local +to the scanning routine and (after the declarations) code which is to be +executed whenever the scanning routine is entered. Other indented or +%{ %} text in the rule section is still copied to the output, but its +meaning is not well-defined and it may well cause compile-time errors +(this feature is present for POSIX compliance. *Note Lex and Posix::, +for other such features). + + Any _indented_ text or text enclosed in `%{' and `%}' is copied +verbatim to the output (with the %{ and %} symbols removed).

It is +used for companion routines which call or are called by the scanner. +The presence of this section is optional; if it is missing, the second +`%%' in the input file may be skipped, too. + + +File: flex.info, Node: Comments in the Input, Prev: User Code Section, Up: Format + +5.4 Comments in the Input +========================= + +Flex supports C-style comments, that is, anything between `/*' and `*/' +is considered a comment. Whenever flex encounters a comment, it copies +the entire comment verbatim to the generated source code. Comments may +appear just about anywhere, but with the following exceptions: + + * Comments may not appear in the Rules Section wherever flex is + expecting a regular expression. This means comments may not appear + at the beginning of a line, or immediately following a list of + scanner states. + + * Comments may not appear on an `%option' line in the Definitions + Section. + + If you want to follow a simple rule, then always begin a comment on a +new line, with one or more whitespace characters before the initial +`/*'). This rule will work anywhere in the input file. + + All the comments in the following example are valid: + + + %{ + /* code block */ + %} + + /* Definitions Section */ + %x STATE_X + + %% + /* Rules Section */ + ruleA /* after regex */ { /* code block */ } /* after code block */ + /* Rules Section (indented) */ + { + ruleC ECHO; + ruleD ECHO; + %{ + /* code block */ + %} + } + %% + /* User Code Section */ + + +File: flex.info, Node: Patterns, Next: Matching, Prev: Format, Up: Top + +6 Patterns +********** + +The patterns in the input (see *Note Rules Section::) are written using +an extended set of regular expressions. These are: + +`x' + match the character 'x' + +`.' + any character (byte) except newline + +`[xyz]' + a "character class"; in this case, the pattern matches either an + 'x', a 'y', or a 'z' + +`[abj-oZ]' + a "character class" with a range in it; matches an 'a', a 'b', any + letter from 'j' through 'o', or a 'Z' + +`[^A-Z]' + a "negated character class", i.e., any character but those in the + class. In this case, any character EXCEPT an uppercase letter. + +`[^A-Z\n]' + any character EXCEPT an uppercase letter or a newline + +`[a-z]{-}[aeiou]' + the lowercase consonants + +`r*' + zero or more r's, where r is any regular expression + +`r+' + one or more r's + +`r?' + zero or one r's (that is, "an optional r") + +`r{2,5}' + anywhere from two to five r's + +`r{2,}' + two or more r's + +`r{4}' + exactly 4 r's + +`{name}' + the expansion of the `name' definition (*note Format::). + +`"[xyz]\"foo"' + the literal string: `[xyz]"foo' + +`\X' + if X is `a', `b', `f', `n', `r', `t', or `v', then the ANSI-C + interpretation of `\x'. Otherwise, a literal `X' (used to escape + operators such as `*') + +`\0' + a NUL character (ASCII code 0) + +`\123' + the character with octal value 123 + +`\x2a' + the character with hexadecimal value 2a + +`(r)' + match an `r'; parentheses are used to override precedence (see + below) + +`(?r-s:pattern)' + apply option `r' and omit option `s' while interpreting pattern. + Options may be zero or more of the characters `i', `s', or `x'. + + `i' means case-insensitive. `-i' means case-sensitive. + + `s' alters the meaning of the `.' syntax to match any single byte + whatsoever. `-s' alters the meaning of `.' to match any byte + except `\n'. + + `x' ignores comments and whitespace in patterns. Whitespace is + ignored unless it is backslash-escaped, contained within `""'s, or + appears inside a character class. + + The following are all valid: + + + (?:foo) same as (foo) + (?i:ab7) same as ([aA][bB]7) + (?-i:ab) same as (ab) + (?s:.) same as [\x00-\xFF] + (?-s:.) same as [^\n] + (?ix-s: a . b) same as ([Aa][^\n][bB]) + (?x:a b) same as ("ab") + (?x:a\ b) same as ("a b") + (?x:a" "b) same as ("a b") + (?x:a[ ]b) same as ("a b") + (?x:a + /* comment */ + b + c) same as (abc) + +`(?# comment )' + omit everything within `()'. The first `)' character encountered + ends the pattern. It is not possible to for the comment to contain + a `)' character. The comment may span lines. + +`rs' + the regular expression `r' followed by the regular expression `s'; + called "concatenation" + +`r|s' + either an `r' or an `s' + +`r/s' + an `r' but only if it is followed by an `s'. The text matched by + `s' is included when determining whether this rule is the longest + match, but is then returned to the input before the action is + executed. So the action only sees the text matched by `r'. This + type of pattern is called "trailing context". (There are some + combinations of `r/s' that flex cannot match correctly. *Note + Limitations::, regarding dangerous trailing context.) + +`^r' + an `r', but only at the beginning of a line (i.e., when just + starting to scan, or right after a newline has been scanned). + +`r$' + an `r', but only at the end of a line (i.e., just before a + newline). Equivalent to `r/\n'. + + Note that `flex''s notion of "newline" is exactly whatever the C + compiler used to compile `flex' interprets `\n' as; in particular, + on some DOS systems you must either filter out `\r's in the input + yourself, or explicitly use `r/\r\n' for `r$'. + +`r' + an `r', but only in start condition `s' (see *Note Start + Conditions:: for discussion of start conditions). + +`r' + same, but in any of start conditions `s1', `s2', or `s3'. + +`<*>r' + an `r' in any start condition, even an exclusive one. + +`<>' + an end-of-file. + +`<>' + an end-of-file when in start condition `s1' or `s2' + + Note that inside of a character class, all regular expression +operators lose their special meaning except escape (`\') and the +character class operators, `-', `]]', and, at the beginning of the +class, `^'. + + The regular expressions listed above are grouped according to +precedence, from highest precedence at the top to lowest at the bottom. +Those grouped together have equal precedence (see special note on the +precedence of the repeat operator, `{}', under the documentation for +the `--posix' POSIX compliance option). For example, + + + foo|bar* + + is the same as + + + (foo)|(ba(r*)) + + since the `*' operator has higher precedence than concatenation, and +concatenation higher than alternation (`|'). This pattern therefore +matches _either_ the string `foo' _or_ the string `ba' followed by +zero-or-more `r''s. To match `foo' or zero-or-more repetitions of the +string `bar', use: + + + foo|(bar)* + + And to match a sequence of zero or more repetitions of `foo' and +`bar': + + + (foo|bar)* + + In addition to characters and ranges of characters, character classes +can also contain "character class expressions". These are expressions +enclosed inside `[': and `:]' delimiters (which themselves must appear +between the `[' and `]' of the character class. Other elements may +occur inside the character class, too). The valid expressions are: + + + [:alnum:] [:alpha:] [:blank:] + [:cntrl:] [:digit:] [:graph:] + [:lower:] [:print:] [:punct:] + [:space:] [:upper:] [:xdigit:] + + These expressions all designate a set of characters equivalent to the +corresponding standard C `isXXX' function. For example, `[:alnum:]' +designates those characters for which `isalnum()' returns true - i.e., +any alphabetic or numeric character. Some systems don't provide +`isblank()', so flex defines `[:blank:]' as a blank or a tab. + + For example, the following character classes are all equivalent: + + + [[:alnum:]] + [[:alpha:][:digit:]] + [[:alpha:][0-9]] + [a-zA-Z0-9] + + A word of caution. Character classes are expanded immediately when +seen in the `flex' input. This means the character classes are +sensitive to the locale in which `flex' is executed, and the resulting +scanner will not be sensitive to the runtime locale. This may or may +not be desirable. + + * If your scanner is case-insensitive (the `-i' flag), then + `[:upper:]' and `[:lower:]' are equivalent to `[:alpha:]'. + + * Character classes with ranges, such as `[a-Z]', should be used with + caution in a case-insensitive scanner if the range spans upper or + lowercase characters. Flex does not know if you want to fold all + upper and lowercase characters together, or if you want the + literal numeric range specified (with no case folding). When in + doubt, flex will assume that you meant the literal numeric range, + and will issue a warning. The exception to this rule is a + character range such as `[a-z]' or `[S-W]' where it is obvious + that you want case-folding to occur. Here are some examples with + the `-i' flag enabled: + + Range Result Literal Range Alternate Range + `[a-t]' ok `[a-tA-T]' + `[A-T]' ok `[a-tA-T]' + `[A-t]' ambiguous `[A-Z\[\\\]_`a-t]' `[a-tA-T]' + `[_-{]' ambiguous `[_`a-z{]' `[_`a-zA-Z{]' + `[@-C]' ambiguous `[@ABC]' `[@A-Z\[\\\]_`abc]' + + * A negated character class such as the example `[^A-Z]' above + _will_ match a newline unless `\n' (or an equivalent escape + sequence) is one of the characters explicitly present in the + negated character class (e.g., `[^A-Z\n]'). This is unlike how + many other regular expression tools treat negated character + classes, but unfortunately the inconsistency is historically + entrenched. Matching newlines means that a pattern like `[^"]*' + can match the entire input unless there's another quote in the + input. + + Flex allows negation of character class expressions by prepending + `^' to the POSIX character class name. + + + [:^alnum:] [:^alpha:] [:^blank:] + [:^cntrl:] [:^digit:] [:^graph:] + [:^lower:] [:^print:] [:^punct:] + [:^space:] [:^upper:] [:^xdigit:] + + Flex will issue a warning if the expressions `[:^upper:]' and + `[:^lower:]' appear in a case-insensitive scanner, since their + meaning is unclear. The current behavior is to skip them entirely, + but this may change without notice in future revisions of flex. + + * The `{-}' operator computes the difference of two character + classes. For example, `[a-c]{-}[b-z]' represents all the + characters in the class `[a-c]' that are not in the class `[b-z]' + (which in this case, is just the single character `a'). The `{-}' + operator is left associative, so `[abc]{-}[b]{-}[c]' is the same + as `[a]'. Be careful not to accidentally create an empty set, + which will never match. + + * The `{+}' operator computes the union of two character classes. + For example, `[a-z]{+}[0-9]' is the same as `[a-z0-9]'. This + operator is useful when preceded by the result of a difference + operation, as in, `[[:alpha:]]{-}[[:lower:]]{+}[q]', which is + equivalent to `[A-Zq]' in the "C" locale. + + * A rule can have at most one instance of trailing context (the `/' + operator or the `$' operator). The start condition, `^', and + `<>' patterns can only occur at the beginning of a pattern, + and, as well as with `/' and `$', cannot be grouped inside + parentheses. A `^' which does not occur at the beginning of a + rule or a `$' which does not occur at the end of a rule loses its + special properties and is treated as a normal character. + + * The following are invalid: + + + foo/bar$ + foobar + + Note that the first of these can be written `foo/bar\n'. + + * The following will result in `$' or `^' being treated as a normal + character: + + + foo|(bar$) + foo|^bar + + If the desired meaning is a `foo' or a + `bar'-followed-by-a-newline, the following could be used (the + special `|' action is explained below, *note Actions::): + + + foo | + bar$ /* action goes here */ + + A similar trick will work for matching a `foo' or a + `bar'-at-the-beginning-of-a-line. + + +File: flex.info, Node: Matching, Next: Actions, Prev: Patterns, Up: Top + +7 How the Input Is Matched +************************** + +When the generated scanner is run, it analyzes its input looking for +strings which match any of its patterns. If it finds more than one +match, it takes the one matching the most text (for trailing context +rules, this includes the length of the trailing part, even though it +will then be returned to the input). If it finds two or more matches of +the same length, the rule listed first in the `flex' input file is +chosen. + + Once the match is determined, the text corresponding to the match +(called the "token") is made available in the global character pointer +`yytext', and its length in the global integer `yyleng'. The "action" +corresponding to the matched pattern is then executed (*note +Actions::), and then the remaining input is scanned for another match. + + If no match is found, then the "default rule" is executed: the next +character in the input is considered matched and copied to the standard +output. Thus, the simplest valid `flex' input is: + + + %% + + which generates a scanner that simply copies its input (one +character at a time) to its output. + + Note that `yytext' can be defined in two different ways: either as a +character _pointer_ or as a character _array_. You can control which +definition `flex' uses by including one of the special directives +`%pointer' or `%array' in the first (definitions) section of your flex +input. The default is `%pointer', unless you use the `-l' lex +compatibility option, in which case `yytext' will be an array. The +advantage of using `%pointer' is substantially faster scanning and no +buffer overflow when matching very large tokens (unless you run out of +dynamic memory). The disadvantage is that you are restricted in how +your actions can modify `yytext' (*note Actions::), and calls to the +`unput()' function destroys the present contents of `yytext', which can +be a considerable porting headache when moving between different `lex' +versions. + + The advantage of `%array' is that you can then modify `yytext' to +your heart's content, and calls to `unput()' do not destroy `yytext' +(*note Actions::). Furthermore, existing `lex' programs sometimes +access `yytext' externally using declarations of the form: + + + extern char yytext[]; + + This definition is erroneous when used with `%pointer', but correct +for `%array'. + + The `%array' declaration defines `yytext' to be an array of `YYLMAX' +characters, which defaults to a fairly large value. You can change the +size by simply #define'ing `YYLMAX' to a different value in the first +section of your `flex' input. As mentioned above, with `%pointer' +yytext grows dynamically to accommodate large tokens. While this means +your `%pointer' scanner can accommodate very large tokens (such as +matching entire blocks of comments), bear in mind that each time the +scanner must resize `yytext' it also must rescan the entire token from +the beginning, so matching such tokens can prove slow. `yytext' +presently does _not_ dynamically grow if a call to `unput()' results in +too much text being pushed back; instead, a run-time error results. + + Also note that you cannot use `%array' with C++ scanner classes +(*note Cxx::). + + +File: flex.info, Node: Actions, Next: Generated Scanner, Prev: Matching, Up: Top + +8 Actions +********* + +Each pattern in a rule has a corresponding "action", which can be any +arbitrary C statement. The pattern ends at the first non-escaped +whitespace character; the remainder of the line is its action. If the +action is empty, then when the pattern is matched the input token is +simply discarded. For example, here is the specification for a program +which deletes all occurrences of `zap me' from its input: + + + %% + "zap me" + + This example will copy all other characters in the input to the +output since they will be matched by the default rule. + + Here is a program which compresses multiple blanks and tabs down to a +single blank, and throws away whitespace found at the end of a line: + + + %% + [ \t]+ putchar( ' ' ); + [ \t]+$ /* ignore this token */ + + If the action contains a `{', then the action spans till the +balancing `}' is found, and the action may cross multiple lines. +`flex' knows about C strings and comments and won't be fooled by braces +found within them, but also allows actions to begin with `%{' and will +consider the action to be all the text up to the next `%}' (regardless +of ordinary braces inside the action). + + An action consisting solely of a vertical bar (`|') means "same as +the action for the next rule". See below for an illustration. + + Actions can include arbitrary C code, including `return' statements +to return a value to whatever routine called `yylex()'. Each time +`yylex()' is called it continues processing tokens from where it last +left off until it either reaches the end of the file or executes a +return. + + Actions are free to modify `yytext' except for lengthening it +(adding characters to its end-these will overwrite later characters in +the input stream). This however does not apply when using `%array' +(*note Matching::). In that case, `yytext' may be freely modified in +any way. + + Actions are free to modify `yyleng' except they should not do so if +the action also includes use of `yymore()' (see below). + + There are a number of special directives which can be included +within an action: + +`ECHO' + copies yytext to the scanner's output. + +`BEGIN' + followed by the name of a start condition places the scanner in the + corresponding start condition (see below). + +`REJECT' + directs the scanner to proceed on to the "second best" rule which + matched the input (or a prefix of the input). The rule is chosen + as described above in *Note Matching::, and `yytext' and `yyleng' + set up appropriately. It may either be one which matched as much + text as the originally chosen rule but came later in the `flex' + input file, or one which matched less text. For example, the + following will both count the words in the input and call the + routine `special()' whenever `frob' is seen: + + + int word_count = 0; + %% + + frob special(); REJECT; + [^ \t\n]+ ++word_count; + + Without the `REJECT', any occurrences of `frob' in the input would + not be counted as words, since the scanner normally executes only + one action per token. Multiple uses of `REJECT' are allowed, each + one finding the next best choice to the currently active rule. For + example, when the following scanner scans the token `abcd', it will + write `abcdabcaba' to the output: + + + %% + a | + ab | + abc | + abcd ECHO; REJECT; + .|\n /* eat up any unmatched character */ + + The first three rules share the fourth's action since they use the + special `|' action. + + `REJECT' is a particularly expensive feature in terms of scanner + performance; if it is used in _any_ of the scanner's actions it + will slow down _all_ of the scanner's matching. Furthermore, + `REJECT' cannot be used with the `-Cf' or `-CF' options (*note + Scanner Options::). + + Note also that unlike the other special actions, `REJECT' is a + _branch_. Code immediately following it in the action will _not_ + be executed. + +`yymore()' + tells the scanner that the next time it matches a rule, the + corresponding token should be _appended_ onto the current value of + `yytext' rather than replacing it. For example, given the input + `mega-kludge' the following will write `mega-mega-kludge' to the + output: + + + %% + mega- ECHO; yymore(); + kludge ECHO; + + First `mega-' is matched and echoed to the output. Then `kludge' + is matched, but the previous `mega-' is still hanging around at the + beginning of `yytext' so the `ECHO' for the `kludge' rule will + actually write `mega-kludge'. + + Two notes regarding use of `yymore()'. First, `yymore()' depends on +the value of `yyleng' correctly reflecting the size of the current +token, so you must not modify `yyleng' if you are using `yymore()'. +Second, the presence of `yymore()' in the scanner's action entails a +minor performance penalty in the scanner's matching speed. + + `yyless(n)' returns all but the first `n' characters of the current +token back to the input stream, where they will be rescanned when the +scanner looks for the next match. `yytext' and `yyleng' are adjusted +appropriately (e.g., `yyleng' will now be equal to `n'). For example, +on the input `foobar' the following will write out `foobarbar': + + + %% + foobar ECHO; yyless(3); + [a-z]+ ECHO; + + An argument of 0 to `yyless()' will cause the entire current input +string to be scanned again. Unless you've changed how the scanner will +subsequently process its input (using `BEGIN', for example), this will +result in an endless loop. + + Note that `yyless()' is a macro and can only be used in the flex +input file, not from other source files. + + `unput(c)' puts the character `c' back onto the input stream. It +will be the next character scanned. The following action will take the +current token and cause it to be rescanned enclosed in parentheses. + + + { + int i; + /* Copy yytext because unput() trashes yytext */ + char *yycopy = strdup( yytext ); + unput( ')' ); + for ( i = yyleng - 1; i >= 0; --i ) + unput( yycopy[i] ); + unput( '(' ); + free( yycopy ); + } + + Note that since each `unput()' puts the given character back at the +_beginning_ of the input stream, pushing back strings must be done +back-to-front. + + An important potential problem when using `unput()' is that if you +are using `%pointer' (the default), a call to `unput()' _destroys_ the +contents of `yytext', starting with its rightmost character and +devouring one character to the left with each call. If you need the +value of `yytext' preserved after a call to `unput()' (as in the above +example), you must either first copy it elsewhere, or build your +scanner using `%array' instead (*note Matching::). + + Finally, note that you cannot put back `EOF' to attempt to mark the +input stream with an end-of-file. + + `input()' reads the next character from the input stream. For +example, the following is one way to eat up C comments: + + + %% + "/*" { + register int c; + + for ( ; ; ) + { + while ( (c = input()) != '*' && + c != EOF ) + ; /* eat up text of comment */ + + if ( c == '*' ) + { + while ( (c = input()) == '*' ) + ; + if ( c == '/' ) + break; /* found the end */ + } + + if ( c == EOF ) + { + error( "EOF in comment" ); + break; + } + } + } + + (Note that if the scanner is compiled using `C++', then `input()' is +instead referred to as yyinput(), in order to avoid a name clash with +the `C++' stream by the name of `input'.) + + `YY_FLUSH_BUFFER()' flushes the scanner's internal buffer so that +the next time the scanner attempts to match a token, it will first +refill the buffer using `YY_INPUT()' (*note Generated Scanner::). This +action is a special case of the more general `yy_flush_buffer()' +function, described below (*note Multiple Input Buffers::) + + `yyterminate()' can be used in lieu of a return statement in an +action. It terminates the scanner and returns a 0 to the scanner's +caller, indicating "all done". By default, `yyterminate()' is also +called when an end-of-file is encountered. It is a macro and may be +redefined. + + +File: flex.info, Node: Generated Scanner, Next: Start Conditions, Prev: Actions, Up: Top + +9 The Generated Scanner +*********************** + +The output of `flex' is the file `lex.yy.c', which contains the +scanning routine `yylex()', a number of tables used by it for matching +tokens, and a number of auxiliary routines and macros. By default, +`yylex()' is declared as follows: + + + int yylex() + { + ... various definitions and the actions in here ... + } + + (If your environment supports function prototypes, then it will be +`int yylex( void )'.) This definition may be changed by defining the +`YY_DECL' macro. For example, you could use: + + + #define YY_DECL float lexscan( a, b ) float a, b; + + to give the scanning routine the name `lexscan', returning a float, +and taking two floats as arguments. Note that if you give arguments to +the scanning routine using a K&R-style/non-prototyped function +declaration, you must terminate the definition with a semi-colon (;). + + `flex' generates `C99' function definitions by default. However flex +does have the ability to generate obsolete, er, `traditional', function +definitions. This is to support bootstrapping gcc on old systems. +Unfortunately, traditional definitions prevent us from using any +standard data types smaller than int (such as short, char, or bool) as +function arguments. For this reason, future versions of `flex' may +generate standard C99 code only, leaving K&R-style functions to the +historians. Currently, if you do *not* want `C99' definitions, then +you must use `%option noansi-definitions'. + + Whenever `yylex()' is called, it scans tokens from the global input +file `yyin' (which defaults to stdin). It continues until it either +reaches an end-of-file (at which point it returns the value 0) or one +of its actions executes a `return' statement. + + If the scanner reaches an end-of-file, subsequent calls are undefined +unless either `yyin' is pointed at a new input file (in which case +scanning continues from that file), or `yyrestart()' is called. +`yyrestart()' takes one argument, a `FILE *' pointer (which can be +NULL, if you've set up `YY_INPUT' to scan from a source other than +`yyin'), and initializes `yyin' for scanning from that file. +Essentially there is no difference between just assigning `yyin' to a +new input file or using `yyrestart()' to do so; the latter is available +for compatibility with previous versions of `flex', and because it can +be used to switch input files in the middle of scanning. It can also +be used to throw away the current input buffer, by calling it with an +argument of `yyin'; but it would be better to use `YY_FLUSH_BUFFER' +(*note Actions::). Note that `yyrestart()' does _not_ reset the start +condition to `INITIAL' (*note Start Conditions::). + + If `yylex()' stops scanning due to executing a `return' statement in +one of the actions, the scanner may then be called again and it will +resume scanning where it left off. + + By default (and for purposes of efficiency), the scanner uses +block-reads rather than simple `getc()' calls to read characters from +`yyin'. The nature of how it gets its input can be controlled by +defining the `YY_INPUT' macro. The calling sequence for `YY_INPUT()' +is `YY_INPUT(buf,result,max_size)'. Its action is to place up to +`max_size' characters in the character array `buf' and return in the +integer variable `result' either the number of characters read or the +constant `YY_NULL' (0 on Unix systems) to indicate `EOF'. The default +`YY_INPUT' reads from the global file-pointer `yyin'. + + Here is a sample definition of `YY_INPUT' (in the definitions +section of the input file): + + + %{ + #define YY_INPUT(buf,result,max_size) \ + { \ + int c = getchar(); \ + result = (c == EOF) ? YY_NULL : (buf[0] = c, 1); \ + } + %} + + This definition will change the input processing to occur one +character at a time. + + When the scanner receives an end-of-file indication from YY_INPUT, it +then checks the `yywrap()' function. If `yywrap()' returns false +(zero), then it is assumed that the function has gone ahead and set up +`yyin' to point to another input file, and scanning continues. If it +returns true (non-zero), then the scanner terminates, returning 0 to +its caller. Note that in either case, the start condition remains +unchanged; it does _not_ revert to `INITIAL'. + + If you do not supply your own version of `yywrap()', then you must +either use `%option noyywrap' (in which case the scanner behaves as +though `yywrap()' returned 1), or you must link with `-lfl' to obtain +the default version of the routine, which always returns 1. + + For scanning from in-memory buffers (e.g., scanning strings), see +*Note Scanning Strings::. *Note Multiple Input Buffers::. + + The scanner writes its `ECHO' output to the `yyout' global (default, +`stdout'), which may be redefined by the user simply by assigning it to +some other `FILE' pointer. + + +File: flex.info, Node: Start Conditions, Next: Multiple Input Buffers, Prev: Generated Scanner, Up: Top + +10 Start Conditions +******************* + +`flex' provides a mechanism for conditionally activating rules. Any +rule whose pattern is prefixed with `' will only be active when the +scanner is in the "start condition" named `sc'. For example, + + + [^"]* { /* eat up the string body ... */ + ... + } + + will be active only when the scanner is in the `STRING' start +condition, and + + + \. { /* handle an escape ... */ + ... + } + + will be active only when the current start condition is either +`INITIAL', `STRING', or `QUOTE'. + + Start conditions are declared in the definitions (first) section of +the input using unindented lines beginning with either `%s' or `%x' +followed by a list of names. The former declares "inclusive" start +conditions, the latter "exclusive" start conditions. A start condition +is activated using the `BEGIN' action. Until the next `BEGIN' action +is executed, rules with the given start condition will be active and +rules with other start conditions will be inactive. If the start +condition is inclusive, then rules with no start conditions at all will +also be active. If it is exclusive, then _only_ rules qualified with +the start condition will be active. A set of rules contingent on the +same exclusive start condition describe a scanner which is independent +of any of the other rules in the `flex' input. Because of this, +exclusive start conditions make it easy to specify "mini-scanners" +which scan portions of the input that are syntactically different from +the rest (e.g., comments). + + If the distinction between inclusive and exclusive start conditions +is still a little vague, here's a simple example illustrating the +connection between the two. The set of rules: + + + %s example + %% + + foo do_something(); + + bar something_else(); + + is equivalent to + + + %x example + %% + + foo do_something(); + + bar something_else(); + + Without the `' qualifier, the `bar' pattern in the +second example wouldn't be active (i.e., couldn't match) when in start +condition `example'. If we just used `' to qualify `bar', +though, then it would only be active in `example' and not in `INITIAL', +while in the first example it's active in both, because in the first +example the `example' start condition is an inclusive `(%s)' start +condition. + + Also note that the special start-condition specifier `<*>' matches +every start condition. Thus, the above example could also have been +written: + + + %x example + %% + + foo do_something(); + + <*>bar something_else(); + + The default rule (to `ECHO' any unmatched character) remains active +in start conditions. It is equivalent to: + + + <*>.|\n ECHO; + + `BEGIN(0)' returns to the original state where only the rules with +no start conditions are active. This state can also be referred to as +the start-condition `INITIAL', so `BEGIN(INITIAL)' is equivalent to +`BEGIN(0)'. (The parentheses around the start condition name are not +required but are considered good style.) + + `BEGIN' actions can also be given as indented code at the beginning +of the rules section. For example, the following will cause the scanner +to enter the `SPECIAL' start condition whenever `yylex()' is called and +the global variable `enter_special' is true: + + + int enter_special; + + %x SPECIAL + %% + if ( enter_special ) + BEGIN(SPECIAL); + + blahblahblah + ...more rules follow... + + To illustrate the uses of start conditions, here is a scanner which +provides two different interpretations of a string like `123.456'. By +default it will treat it as three tokens, the integer `123', a dot +(`.'), and the integer `456'. But if the string is preceded earlier in +the line by the string `expect-floats' it will treat it as a single +token, the floating-point number `123.456': + + + %{ + #include + %} + %s expect + + %% + expect-floats BEGIN(expect); + + [0-9]+@samp{.}[0-9]+ { + printf( "found a float, = %f\n", + atof( yytext ) ); + } + \n { + /* that's the end of the line, so + * we need another "expect-number" + * before we'll recognize any more + * numbers + */ + BEGIN(INITIAL); + } + + [0-9]+ { + printf( "found an integer, = %d\n", + atoi( yytext ) ); + } + + "." printf( "found a dot\n" ); + + Here is a scanner which recognizes (and discards) C comments while +maintaining a count of the current input line. + + + %x comment + %% + int line_num = 1; + + "/*" BEGIN(comment); + + [^*\n]* /* eat anything that's not a '*' */ + "*"+[^*/\n]* /* eat up '*'s not followed by '/'s */ + \n ++line_num; + "*"+"/" BEGIN(INITIAL); + + This scanner goes to a bit of trouble to match as much text as +possible with each rule. In general, when attempting to write a +high-speed scanner try to match as much possible in each rule, as it's +a big win. + + Note that start-conditions names are really integer values and can +be stored as such. Thus, the above could be extended in the following +fashion: + + + %x comment foo + %% + int line_num = 1; + int comment_caller; + + "/*" { + comment_caller = INITIAL; + BEGIN(comment); + } + + ... + + "/*" { + comment_caller = foo; + BEGIN(comment); + } + + [^*\n]* /* eat anything that's not a '*' */ + "*"+[^*/\n]* /* eat up '*'s not followed by '/'s */ + \n ++line_num; + "*"+"/" BEGIN(comment_caller); + + Furthermore, you can access the current start condition using the +integer-valued `YY_START' macro. For example, the above assignments to +`comment_caller' could instead be written + + + comment_caller = YY_START; + + Flex provides `YYSTATE' as an alias for `YY_START' (since that is +what's used by AT&T `lex'). + + For historical reasons, start conditions do not have their own +name-space within the generated scanner. The start condition names are +unmodified in the generated scanner and generated header. *Note +option-header::. *Note option-prefix::. + + Finally, here's an example of how to match C-style quoted strings +using exclusive start conditions, including expanded escape sequences +(but not including checking for a string that's too long): + + + %x str + + %% + char string_buf[MAX_STR_CONST]; + char *string_buf_ptr; + + + \" string_buf_ptr = string_buf; BEGIN(str); + + \" { /* saw closing quote - all done */ + BEGIN(INITIAL); + *string_buf_ptr = '\0'; + /* return string constant token type and + * value to parser + */ + } + + \n { + /* error - unterminated string constant */ + /* generate error message */ + } + + \\[0-7]{1,3} { + /* octal escape sequence */ + int result; + + (void) sscanf( yytext + 1, "%o", &result ); + + if ( result > 0xff ) + /* error, constant is out-of-bounds */ + + *string_buf_ptr++ = result; + } + + \\[0-9]+ { + /* generate error - bad escape sequence; something + * like '\48' or '\0777777' + */ + } + + \\n *string_buf_ptr++ = '\n'; + \\t *string_buf_ptr++ = '\t'; + \\r *string_buf_ptr++ = '\r'; + \\b *string_buf_ptr++ = '\b'; + \\f *string_buf_ptr++ = '\f'; + + \\(.|\n) *string_buf_ptr++ = yytext[1]; + + [^\\\n\"]+ { + char *yptr = yytext; + + while ( *yptr ) + *string_buf_ptr++ = *yptr++; + } + + Often, such as in some of the examples above, you wind up writing a +whole bunch of rules all preceded by the same start condition(s). Flex +makes this a little easier and cleaner by introducing a notion of start +condition "scope". A start condition scope is begun with: + + + { + + where `SCs' is a list of one or more start conditions. Inside the +start condition scope, every rule automatically has the prefix `SCs>' +applied to it, until a `}' which matches the initial `{'. So, for +example, + + + { + "\\n" return '\n'; + "\\r" return '\r'; + "\\f" return '\f'; + "\\0" return '\0'; + } + + is equivalent to: + + + "\\n" return '\n'; + "\\r" return '\r'; + "\\f" return '\f'; + "\\0" return '\0'; + + Start condition scopes may be nested. + + The following routines are available for manipulating stacks of +start conditions: + + -- Function: void yy_push_state ( int `new_state' ) + pushes the current start condition onto the top of the start + condition stack and switches to `new_state' as though you had used + `BEGIN new_state' (recall that start condition names are also + integers). + + -- Function: void yy_pop_state () + pops the top of the stack and switches to it via `BEGIN'. + + -- Function: int yy_top_state () + returns the top of the stack without altering the stack's contents. + + The start condition stack grows dynamically and so has no built-in +size limitation. If memory is exhausted, program execution aborts. + + To use start condition stacks, your scanner must include a `%option +stack' directive (*note Scanner Options::). + + +File: flex.info, Node: Multiple Input Buffers, Next: EOF, Prev: Start Conditions, Up: Top + +11 Multiple Input Buffers +************************* + +Some scanners (such as those which support "include" files) require +reading from several input streams. As `flex' scanners do a large +amount of buffering, one cannot control where the next input will be +read from by simply writing a `YY_INPUT()' which is sensitive to the +scanning context. `YY_INPUT()' is only called when the scanner reaches +the end of its buffer, which may be a long time after scanning a +statement such as an `include' statement which requires switching the +input source. + + To negotiate these sorts of problems, `flex' provides a mechanism +for creating and switching between multiple input buffers. An input +buffer is created by using: + + -- Function: YY_BUFFER_STATE yy_create_buffer ( FILE *file, int size ) + + which takes a `FILE' pointer and a size and creates a buffer +associated with the given file and large enough to hold `size' +characters (when in doubt, use `YY_BUF_SIZE' for the size). It returns +a `YY_BUFFER_STATE' handle, which may then be passed to other routines +(see below). The `YY_BUFFER_STATE' type is a pointer to an opaque +`struct yy_buffer_state' structure, so you may safely initialize +`YY_BUFFER_STATE' variables to `((YY_BUFFER_STATE) 0)' if you wish, and +also refer to the opaque structure in order to correctly declare input +buffers in source files other than that of your scanner. Note that the +`FILE' pointer in the call to `yy_create_buffer' is only used as the +value of `yyin' seen by `YY_INPUT'. If you redefine `YY_INPUT()' so it +no longer uses `yyin', then you can safely pass a NULL `FILE' pointer to +`yy_create_buffer'. You select a particular buffer to scan from using: + + -- Function: void yy_switch_to_buffer ( YY_BUFFER_STATE new_buffer ) + + The above function switches the scanner's input buffer so subsequent +tokens will come from `new_buffer'. Note that `yy_switch_to_buffer()' +may be used by `yywrap()' to set things up for continued scanning, +instead of opening a new file and pointing `yyin' at it. If you are +looking for a stack of input buffers, then you want to use +`yypush_buffer_state()' instead of this function. Note also that +switching input sources via either `yy_switch_to_buffer()' or +`yywrap()' does _not_ change the start condition. + + -- Function: void yy_delete_buffer ( YY_BUFFER_STATE buffer ) + + is used to reclaim the storage associated with a buffer. (`buffer' +can be NULL, in which case the routine does nothing.) You can also +clear the current contents of a buffer using: + + -- Function: void yypush_buffer_state ( YY_BUFFER_STATE buffer ) + + This function pushes the new buffer state onto an internal stack. +The pushed state becomes the new current state. The stack is maintained +by flex and will grow as required. This function is intended to be used +instead of `yy_switch_to_buffer', when you want to change states, but +preserve the current state for later use. + + -- Function: void yypop_buffer_state ( ) + + This function removes the current state from the top of the stack, +and deletes it by calling `yy_delete_buffer'. The next state on the +stack, if any, becomes the new current state. + + -- Function: void yy_flush_buffer ( YY_BUFFER_STATE buffer ) + + This function discards the buffer's contents, so the next time the +scanner attempts to match a token from the buffer, it will first fill +the buffer anew using `YY_INPUT()'. + + -- Function: YY_BUFFER_STATE yy_new_buffer ( FILE *file, int size ) + + is an alias for `yy_create_buffer()', provided for compatibility +with the C++ use of `new' and `delete' for creating and destroying +dynamic objects. + + `YY_CURRENT_BUFFER' macro returns a `YY_BUFFER_STATE' handle to the +current buffer. It should not be used as an lvalue. + + Here are two examples of using these features for writing a scanner +which expands include files (the `<>' feature is discussed below). + + This first example uses yypush_buffer_state and yypop_buffer_state. +Flex maintains the stack internally. + + + /* the "incl" state is used for picking up the name + * of an include file + */ + %x incl + %% + include BEGIN(incl); + + [a-z]+ ECHO; + [^a-z\n]*\n?

For example, it +could be #define'd to call a routine to convert yytext to lower-case. +When `YY_USER_ACTION' is invoked, the variable `yy_act' gives the +number of the matched rule (rules are numbered starting with 1). +Suppose you want to profile how often each of your rules is matched. +The following would do the trick: + + + #define YY_USER_ACTION ++ctr[yy_act] + + where `ctr' is an array to hold the counts for the different rules. +Note that the macro `YY_NUM_RULES' gives the total number of rules +(including the default rule), even if you use `-s)', so a correct +declaration for `ctr' is: + + + int ctr[YY_NUM_RULES]; + + The macro `YY_USER_INIT' may be defined to provide an action which +is always executed before the first scan (and before the scanner's +internal initializations are done). For example, it could be used to +call a routine to read in a data table or open a logging file. + + The macro `yy_set_interactive(is_interactive)' can be used to +control whether the current buffer is considered "interactive". An +interactive buffer is processed more slowly, but must be used when the +scanner's input source is indeed interactive to avoid problems due to +waiting to fill buffers (see the discussion of the `-I' flag in *Note +Scanner Options::). A non-zero value in the macro invocation marks the +buffer as interactive, a zero value as non-interactive. Note that use +of this macro overrides `%option always-interactive' or `%option +never-interactive' (*note Scanner Options::). `yy_set_interactive()' +must be invoked prior to beginning to scan the buffer that is (or is +not) to be considered interactive. + + The macro `yy_set_bol(at_bol)' can be used to control whether the +current buffer's scanning context for the next token match is done as +though at the beginning of a line. A non-zero macro argument makes +rules anchored with `^' active, while a zero argument makes `^' rules +inactive. + + The macro `YY_AT_BOL()' returns true if the next token scanned from +the current buffer will have `^' rules active, false otherwise. + + In the generated scanner, the actions are all gathered in one large +switch statement and separated using `YY_BREAK', which may be +redefined. By default, it is simply a `break', to separate each rule's +action from the following rule's. Redefining `YY_BREAK' allows, for +example, C++ users to #define YY_BREAK to do nothing (while being very +careful that every rule ends with a `break' or a `return'!) to avoid +suffering from unreachable statement warnings where because a rule's +action ends with `return', the `YY_BREAK' is inaccessible. + + +File: flex.info, Node: User Values, Next: Yacc, Prev: Misc Macros, Up: Top + +14 Values Available To the User +******************************* + +This chapter summarizes the various values available to the user in the +rule actions. + +`char *yytext' + holds the text of the current token. It may be modified but not + lengthened (you cannot append characters to the end). + + If the special directive `%array' appears in the first section of + the scanner description, then `yytext' is instead declared `char + yytext[YYLMAX]', where `YYLMAX' is a macro definition that you can + redefine in the first section if you don't like the default value + (generally 8KB). Using `%array' results in somewhat slower + scanners, but the value of `yytext' becomes immune to calls to + `unput()', which potentially destroy its value when `yytext' is a + character pointer. The opposite of `%array' is `%pointer', which + is the default. + + You cannot use `%array' when generating C++ scanner classes (the + `-+' flag). + +`int yyleng' + holds the length of the current token. + +`FILE *yyin' + is the file which by default `flex' reads from. It may be + redefined but doing so only makes sense before scanning begins or + after an EOF has been encountered. Changing it in the midst of + scanning will have unexpected results since `flex' buffers its + input; use `yyrestart()' instead. Once scanning terminates + because an end-of-file has been seen, you can assign `yyin' at the + new input file and then call the scanner again to continue + scanning. + +`void yyrestart( FILE *new_file )' + may be called to point `yyin' at the new input file. The + switch-over to the new file is immediate (any previously + buffered-up input is lost).

The routine is supposed to +return the type of the next token as well as putting any associated +value in the global `yylval'. To use `flex' with `yacc', one specifies +the `-d' option to `yacc' to instruct it to generate the file `y.tab.h' +containing definitions of all the `%tokens' appearing in the `yacc' +input. This file is then included in the `flex' scanner. For example, +if one of the tokens is `TOK_NUMBER', part of the scanner might look +like: + + + %{ + #include "y.tab.h" + %} + + %% + + [0-9]+ yylval = atoi( yytext ); return TOK_NUMBER; + + +File: flex.info, Node: Scanner Options, Next: Performance, Prev: Yacc, Up: Top + +16 Scanner Options +****************** + +The various `flex' options are categorized by function in the following +menu.

The +second line specifies that we are being careful. The third line asks +flex to track line numbers. The last line tells flex what to name the +files. (The options can be specified in any order.

You can specify multiple options with a +single `%option' directive, and multiple directives in the first +section of your flex input file. + + Most options are given simply as names, optionally preceded by the +word `no' (with no intervening whitespace) to negate their meaning. +The names are the same as their long-option equivalents (but without the +leading `--' ). + + `flex' scans your rule actions to determine whether you use the +`REJECT' or `yymore()' features.

The + case of letters given in the `flex' input patterns will be ignored, + and tokens in the input will be matched regardless of case. The + matched text given in `yytext' will have the preserved case (i.e., + it will not be folded). For tricky behavior, see *Note case and + character ranges::. + +`-l, --lex-compat, `%option lex-compat'' + turns on maximum compatibility with the original AT&T `lex' + implementation. Note that this does not mean _full_ compatibility. + Use of this option costs a considerable amount of performance, and + it cannot be used with the `--c++', `--full', `--fast', `-Cf', or + `-CF' options. For details on the compatibilities it provides, see + *Note Lex and Posix::. This option also results in the name + `YY_FLEX_LEX_COMPAT' being `#define''d in the generated scanner. + +`-B, --batch, `%option batch'' + instructs `flex' to generate a "batch" scanner, the opposite of + _interactive_ scanners generated by `--interactive' (see below). + In general, you use `-B' when you are _certain_ that your scanner + will never be used interactively, and you want to squeeze a + _little_ more performance out of it. If your goal is instead to + squeeze out a _lot_ more performance, you should be using the + `-Cf' or `-CF' options, which turn on `--batch' automatically + anyway. + +`-I, --interactive, `%option interactive'' + instructs `flex' to generate an interactive scanner. An + interactive scanner is one that only looks ahead to decide what + token has been matched if it absolutely must. It turns out that + always looking one extra character ahead, even if the scanner has + already seen enough text to disambiguate the current token, is a + bit faster than only looking ahead when necessary. But scanners + that always look ahead give dreadful interactive performance; for + example, when a user types a newline, it is not recognized as a + newline token until they enter _another_ token, which often means + typing in another whole line. + + `flex' scanners default to `interactive' unless you use the `-Cf' + or `-CF' table-compression options (*note Performance::). That's + because if you're looking for high-performance you should be using + one of these options, so if you didn't, `flex' assumes you'd + rather trade off a bit of run-time performance for intuitive + interactive behavior. Note also that you _cannot_ use + `--interactive' in conjunction with `-Cf' or `-CF'. Thus, this + option is not really needed; it is on by default for all those + cases in which it is allowed. + + You can force a scanner to _not_ be interactive by using `--batch' + +`-7, --7bit, `%option 7bit'' + instructs `flex' to generate a 7-bit scanner, i.e., one which can + only recognize 7-bit characters in its input. The advantage of + using `--7bit' is that the scanner's tables can be up to half the + size of those generated using the `--8bit'. The disadvantage is + that such scanners often hang or crash if their input contains an + 8-bit character. + + Note, however, that unless you generate your scanner using the + `-Cf' or `-CF' table compression options, use of `--7bit' will + save only a small amount of table space, and make your scanner + considerably less portable. `Flex''s default behavior is to + generate an 8-bit scanner unless you use the `-Cf' or `-CF', in + which case `flex' defaults to generating 7-bit scanners unless + your site was always configured to generate 8-bit scanners (as will + often be the case with non-USA sites). You can tell whether flex + generated a 7-bit or an 8-bit scanner by inspecting the flag + summary in the `--verbose' output as described above. + + Note that if you use `-Cfe' or `-CFe' `flex' still defaults to + generating an 8-bit scanner, since usually with these compression + options full 8-bit tables are not much more expensive than 7-bit + tables. + +`-8, --8bit, `%option 8bit'' + instructs `flex' to generate an 8-bit scanner, i.e., one which can + recognize 8-bit characters. This flag is only needed for scanners + generated using `-Cf' or `-CF', as otherwise flex defaults to + generating an 8-bit scanner anyway. + + See the discussion of `--7bit' above for `flex''s default behavior + and the tradeoffs between 7-bit and 8-bit scanners. + +`--default, `%option default'' + generate the default rule. + +`--always-interactive, `%option always-interactive'' + instructs flex to generate a scanner which always considers its + input _interactive_. Normally, on each new input file the scanner + calls `isatty()' in an attempt to determine whether the scanner's + input source is interactive and thus should be read a character at + a time. When this option is used, however, then no such call is + made. + +`--never-interactive, `--never-interactive'' + instructs flex to generate a scanner which never considers its + input interactive. This is the opposite of `always-interactive'. + +`-X, --posix, `%option posix'' + turns on maximum compatibility with the POSIX 1003.2-1992 + definition of `lex'. Since `flex' was originally designed to + implement the POSIX definition of `lex' this generally involves + very few changes in behavior. At the current writing the known + differences between `flex' and the POSIX standard are: + + * In POSIX and AT&T `lex', the repeat operator, `{}', has lower + precedence than concatenation (thus `ab{3}' yields `ababab'). + Most POSIX utilities use an Extended Regular Expression (ERE) + precedence that has the precedence of the repeat operator + higher than concatenation (which causes `ab{3}' to yield + `abbb'). By default, `flex' places the precedence of the + repeat operator higher than concatenation which matches the + ERE processing of other POSIX utilities. When either + `--posix' or `-l' are specified, `flex' will use the + traditional AT&T and POSIX-compliant precedence for the + repeat operator where concatenation has higher precedence + than the repeat operator. + +`--stack, `%option stack'' + enables the use of start condition stacks (*note Start + Conditions::). + +`--stdinit, `%option stdinit'' + if set (i.e., %option stdinit) initializes `yyin' and `yyout' to + `stdin' and `stdout', instead of the default of `NULL'. Some + existing `lex' programs depend on this behavior, even though it is + not compliant with ANSI C, which does not require `stdin' and + `stdout' to be compile-time constant. In a reentrant scanner, + however, this is not a problem since initialization is performed + in `yylex_init' at runtime. + +`--yylineno, `%option yylineno'' + directs `flex' to generate a scanner that maintains the number of + the current line read from its input in the global variable + `yylineno'. This option is implied by `%option lex-compat'. In a + reentrant C scanner, the macro `yylineno' is accessible regardless + of the value of `%option yylineno', however, its value is not + modified by `flex' unless `%option yylineno' is enabled. + +`--yywrap, `%option yywrap'' + if unset (i.e., `--noyywrap)', makes the scanner not call + `yywrap()' upon an end-of-file, but simply assume that there are no + more files to scan (until the user points `yyin' at a new file and + calls `yylex()' again). + + + +File: flex.info, Node: Code-Level And API Options, Next: Options for Scanner Speed and Size, Prev: Options Affecting Scanner Behavior, Up: Scanner Options + +16.3 Code-Level And API Options +=============================== + +`--ansi-definitions, `%option ansi-definitions'' + instruct flex to generate ANSI C99 definitions for functions. + This option is enabled by default.

On some RISC architectures, fetching and + manipulating longwords is more efficient than with + smaller-sized units such as shortwords. This option can + quadruple the size of the tables used by your scanner. + + `-Ce, --ecs, `%option ecs'' + directs `flex' to construct "equivalence classes", i.e., sets + of characters which have identical lexical properties (for + example, if the only appearance of digits in the `flex' input + is in the character class "[0-9]" then the digits '0', '1', + ..., '9' will all be put in the same equivalence class). + Equivalence classes usually give dramatic reductions in the + final table/object file sizes (typically a factor of 2-5) and + are pretty cheap performance-wise (one array look-up per + character scanned). + + `-Cf' + specifies that the "full" scanner tables should be generated - + `flex' should not compress the tables by taking advantages of + similar transition functions for different states. + + `-CF' + specifies that the alternate fast scanner representation + (described above under the `--fast' flag) should be used. + This option cannot be used with `--c++'. + + `-Cm, --meta-ecs, `%option meta-ecs'' + directs `flex' to construct "meta-equivalence classes", which + are sets of equivalence classes (or characters, if equivalence + classes are not being used) that are commonly used together. + Meta-equivalence classes are often a big win when using + compressed tables, but they have a moderate performance + impact (one or two `if' tests and one array look-up per + character scanned). + + `-Cr, --read, `%option read'' + causes the generated scanner to _bypass_ use of the standard + I/O library (`stdio') for input. Instead of calling + `fread()' or `getc()', the scanner will use the `read()' + system call, resulting in a performance gain which varies + from system to system, but in general is probably negligible + unless you are also using `-Cf' or `-CF'. Using `-Cr' can + cause strange behavior if, for example, you read from `yyin' + using `stdio' prior to calling the scanner (because the + scanner will miss whatever text your previous reads left in + the `stdio' input buffer). `-Cr' has no effect if you define + `YY_INPUT()' (*note Generated Scanner::). + + The options `-Cf' or `-CF' and `-Cm' do not make sense together - + there is no opportunity for meta-equivalence classes if the table + is not being compressed.

This option + is equivalent to `--Cfr' + +`-F, --fast, `%option fast'' + specifies that the _fast_ scanner table representation should be + used (and `stdio' bypassed). This representation is about as fast + as the full table representation `--full', and for some sets of + patterns will be considerably smaller (and for others, larger).

This is a list of + scanner states which require backing up and the input characters on + which they do so. By adding rules one can remove backing-up + states.

Only users who wish to squeeze every last + cycle out of their scanners need worry about this option. (*note + Performance::). + +`-d, --debug, `%option debug'' + makes the generated scanner run in "debug" mode.

The report consists of + comments regarding features of the `flex' input file which will + cause a serious loss of performance in the resulting scanner. If + you give the flag twice, you will also get comments regarding + features that lead to minor performance losses. + + Note that the use of `REJECT', and variable trailing context + (*note Limitations::) entails a substantial performance penalty; + use of `yymore()', the `^' operator, and the `--interactive' flag + entail minor performance penalties. + +`-s, --nodefault, `%option nodefault'' + causes the _default rule_ (that unmatched scanner input is echoed + to `stdout)' to be suppressed. If the scanner encounters input + that does not match any of its rules, it aborts with an error. + This option is useful for finding holes in a scanner's rule set. + +`-T, --trace, `%option trace'' + makes `flex' run in "trace" mode.

It has been optimized for dealing well with large sets of +rules. Aside from the effects on scanner speed of the table compression +`-C' options outlined above, there are a number of options/actions +which degrade performance. These are, from most expensive to least: + + + REJECT + arbitrary trailing context + + pattern sets that require backing up + %option yylineno + %array + + %option interactive + %option always-interactive + + @samp{^} beginning-of-line operator + yymore() + + with the first two all being quite expensive and the last two being +quite cheap. Note also that `unput()' is implemented as a routine call +that potentially does quite a bit of work, while `yyless()' is a +quite-cheap macro. So if you are just putting back some excess text you +scanned, use `yyless()'. + + `REJECT' should be avoided at all costs when performance is +important. It is a particularly expensive option. + + There is one case when `%option yylineno' can be expensive. That is +when your patterns match long tokens that could _possibly_ contain a +newline character. There is no performance penalty for rules that can +not possibly match newlines, since flex does not need to check them for +newlines. In general, you should avoid rules such as `[^f]+', which +match very long tokens, including newlines, and may possibly match your +entire file! A better approach is to separate `[^f]+' into two rules: + + + %option yylineno + %% + [^f\n]+ + \n+ + + The above scanner does not incur a performance penalty. + + Getting rid of backing up is messy and often may be an enormous +amount of work for a complicated scanner. In principal, one begins by +using the `-b' flag to generate a `lex.backup' file. For example, on +the input: + + + %% + foo return TOK_KEYWORD; + foobar return TOK_KEYWORD; + + the file looks like: + + + State #6 is non-accepting - + associated rule line numbers: + 2 3 + out-transitions: [ o ] + jam-transitions: EOF [ \001-n p-\177 ] + + State #8 is non-accepting - + associated rule line numbers: + 3 + out-transitions: [ a ] + jam-transitions: EOF [ \001-` b-\177 ] + + State #9 is non-accepting - + associated rule line numbers: + 3 + out-transitions: [ r ] + jam-transitions: EOF [ \001-q s-\177 ] + + Compressed tables always back up. + + The first few lines tell us that there's a scanner state in which it +can make a transition on an 'o' but not on any other character, and +that in that state the currently scanned text does not match any rule. +The state occurs when trying to match the rules found at lines 2 and 3 +in the input file. If the scanner is in that state and then reads +something other than an 'o', it will have to back up to find a rule +which is matched. With a bit of headscratching one can see that this +must be the state it's in when it has seen `fo'. When this has +happened, if anything other than another `o' is seen, the scanner will +have to back up to simply match the `f' (by the default rule). + + The comment regarding State #8 indicates there's a problem when +`foob' has been scanned. Indeed, on any character other than an `a', +the scanner will have to back up to accept "foo". Similarly, the +comment for State #9 concerns when `fooba' has been scanned and an `r' +does not follow. + + The final comment reminds us that there's no point going to all the +trouble of removing backing up from the rules unless we're using `-Cf' +or `-CF', since there's no performance gain doing so with compressed +scanners. + + The way to remove the backing up is to add "error" rules: + + + %% + foo return TOK_KEYWORD; + foobar return TOK_KEYWORD; + + fooba | + foob | + fo { + /* false alarm, not really a keyword */ + return TOK_ID; + } + + Eliminating backing up among a list of keywords can also be done +using a "catch-all" rule: + + + %% + foo return TOK_KEYWORD; + foobar return TOK_KEYWORD; + + [a-z]+ return TOK_ID; + + This is usually the best solution when appropriate. + + Backing up messages tend to cascade. With a complicated set of rules +it's not uncommon to get hundreds of messages. If one can decipher +them, though, it often only takes a dozen or so rules to eliminate the +backing up (though it's easy to make a mistake and have an error rule +accidentally match a valid token. A possible future `flex' feature +will be to automatically add rules to eliminate backing up). + + It's important to keep in mind that you gain the benefits of +eliminating backing up only if you eliminate _every_ instance of +backing up. Leaving just one means you gain nothing. + + _Variable_ trailing context (where both the leading and trailing +parts do not have a fixed length) entails almost the same performance +loss as `REJECT' (i.e., substantial). So when possible a rule like: + + + %% + mouse|rat/(cat|dog) run(); + + is better written: + + + %% + mouse/cat|dog run(); + rat/cat|dog run(); + + or as + + + %% + mouse|rat/cat run(); + mouse|rat/dog run(); + + Note that here the special '|' action does _not_ provide any +savings, and can even make things worse (*note Limitations::). + + Another area where the user can increase a scanner's performance (and +one that's easier to implement) arises from the fact that the longer the +tokens matched, the faster the scanner will run. This is because with +long tokens the processing of most input characters takes place in the +(short) inner scanning loop, and does not often have to go through the +additional work of setting up the scanning environment (e.g., `yytext') +for the action. Recall the scanner for C comments: + + + %x comment + %% + int line_num = 1; + + "/*" BEGIN(comment); + + [^*\n]* + "*"+[^*/\n]* + \n ++line_num; + "*"+"/" BEGIN(INITIAL); + + This could be sped up by writing it as: + + + %x comment + %% + int line_num = 1; + + "/*" BEGIN(comment); + + [^*\n]* + [^*\n]*\n ++line_num; + "*"+[^*/\n]* + "*"+[^*/\n]*\n ++line_num; + "*"+"/" BEGIN(INITIAL); + + Now instead of each newline requiring the processing of another +action, recognizing the newlines is distributed over the other rules to +keep the matched text as long as possible. Note that _adding_ rules +does _not_ slow down the scanner! The speed of the scanner is +independent of the number of rules or (modulo the considerations given +at the beginning of this section) how complicated the rules are with +regard to operators such as `*' and `|'. + + A final example in speeding up a scanner: suppose you want to scan +through a file containing identifiers and keywords, one per line and +with no other extraneous characters, and recognize all the keywords. A +natural first approach is: + + + %% + asm | + auto | + break | + ... etc ... + volatile | + while /* it's a keyword */ + + .|\n /* it's not a keyword */ + + To eliminate the back-tracking, introduce a catch-all rule: + + + %% + asm | + auto | + break | + ... etc ... + volatile | + while /* it's a keyword */ + + [a-z]+ | + .|\n /* it's not a keyword */ + + Now, if it's guaranteed that there's exactly one word per line, then +we can reduce the total number of matches by a half by merging in the +recognition of newlines with that of the other tokens: + + + %% + asm\n | + auto\n | + break\n | + ... etc ... + volatile\n | + while\n /* it's a keyword */ + + [a-z]+\n | + .|\n /* it's not a keyword */ + + One has to be careful here, as we have now reintroduced backing up +into the scanner. In particular, while _we_ know that there will never +be any characters in the input stream other than letters or newlines, +`flex' can't figure this out, and it will plan for possibly needing to +back up when it has scanned a token like `auto' and then the next +character is something other than a newline or a letter. Previously it +would then just match the `auto' rule and be done, but now it has no +`auto' rule, only a `auto\n' rule. To eliminate the possibility of +backing up, we could either duplicate all rules but without final +newlines, or, since we never expect to encounter such an input and +therefore don't how it's classified, we can introduce one more +catch-all rule, this one which doesn't include a newline: + + + %% + asm\n | + auto\n | + break\n | + ... etc ... + volatile\n | + while\n /* it's a keyword */ + + [a-z]+\n | + [a-z]+ | + .|\n /* it's not a keyword */ + + Compiled with `-Cf', this is about as fast as one can get a `flex' +scanner to go for this particular problem. + + A final note: `flex' is slow when matching `NUL's, particularly when +a token contains multiple `NUL's. It's best to write rules which match +_short_ amounts of text if it's anticipated that the text will often +include `NUL's. + + Another final note regarding performance: as mentioned in *Note +Matching::, dynamically resizing `yytext' to accommodate huge tokens is +a slow process because it presently requires that the (huge) token be +rescanned from the beginning. Thus if performance is vital, you should +attempt to match "large" quantities of text but not "huge" quantities, +where the cutoff between the two is at about 8K characters per token. + + +File: flex.info, Node: Cxx, Next: Reentrant, Prev: Performance, Up: Top + +18 Generating C++ Scanners +************************** + +*IMPORTANT*: the present form of the scanning class is _experimental_ +and may change considerably between major releases. + + `flex' provides two different ways to generate scanners for use with +C++. The first way is to simply compile a scanner generated by `flex' +using a C++ compiler instead of a C compiler. You should not encounter +any compilation errors (*note Reporting Bugs::). You can then use C++ +code in your rule actions instead of C code. Note that the default +input source for your scanner remains `yyin', and default echoing is +still done to `yyout'. Both of these remain `FILE *' variables and not +C++ _streams_. + + You can also use `flex' to generate a C++ scanner class, using the +`-+' option (or, equivalently, `%option c++)', which is automatically +specified if the name of the `flex' executable ends in a '+', such as +`flex++'. When using this option, `flex' defaults to generating the +scanner to the file `lex.yy.cc' instead of `lex.yy.c'. The generated +scanner includes the header file `FlexLexer.h', which defines the +interface to two C++ classes. + + The first class, `FlexLexer', provides an abstract base class +defining the general scanner class interface. It provides the +following member functions: + +`const char* YYText()' + returns the text of the most recently matched token, the + equivalent of `yytext'. + +`int YYLeng()' + returns the length of the most recently matched token, the + equivalent of `yyleng'. + +`int lineno() const' + returns the current input line number (see `%option yylineno)', or + `1' if `%option yylineno' was not used. + +`void set_debug( int flag )' + sets the debugging flag for the scanner, equivalent to assigning to + `yy_flex_debug' (*note Scanner Options::). Note that you must + build the scanner using `%option debug' to include debugging + information in it. + +`int debug() const' + returns the current setting of the debugging flag. + + Also provided are member functions equivalent to +`yy_switch_to_buffer()', `yy_create_buffer()' (though the first +argument is an `istream*' object pointer and not a `FILE*)', +`yy_flush_buffer()', `yy_delete_buffer()', and `yyrestart()' (again, +the first argument is a `istream*' object pointer). + + The second class defined in `FlexLexer.h' is `yyFlexLexer', which is +derived from `FlexLexer'. It defines the following additional member +functions: + +`yyFlexLexer( istream* arg_yyin = 0, ostream* arg_yyout = 0 )' + constructs a `yyFlexLexer' object using the given streams for input + and output. If not specified, the streams default to `cin' and + `cout', respectively. + +`virtual int yylex()' + performs the same role is `yylex()' does for ordinary `flex' + scanners: it scans the input stream, consuming tokens, until a + rule's action returns a value. If you derive a subclass `S' from + `yyFlexLexer' and want to access the member functions and variables + of `S' inside `yylex()', then you need to use `%option + yyclass="S"' to inform `flex' that you will be using that subclass + instead of `yyFlexLexer'. In this case, rather than generating + `yyFlexLexer::yylex()', `flex' generates `S::yylex()' (and also + generates a dummy `yyFlexLexer::yylex()' that calls + `yyFlexLexer::LexerError()' if called). + +`virtual void switch_streams(istream* new_in = 0, ostream* new_out = 0)' + reassigns `yyin' to `new_in' (if non-null) and `yyout' to + `new_out' (if non-null), deleting the previous input buffer if + `yyin' is reassigned. + +`int yylex( istream* new_in, ostream* new_out = 0 )' + first switches the input streams via `switch_streams( new_in, + new_out )' and then returns the value of `yylex()'. + + In addition, `yyFlexLexer' defines the following protected virtual +functions which you can redefine in derived classes to tailor the +scanner: + +`virtual int LexerInput( char* buf, int max_size )' + reads up to `max_size' characters into `buf' and returns the + number of characters read. To indicate end-of-input, return 0 + characters. Note that `interactive' scanners (see the `-B' and + `-I' flags in *Note Scanner Options::) define the macro + `YY_INTERACTIVE'. If you redefine `LexerInput()' and need to take + different actions depending on whether or not the scanner might be + scanning an interactive input source, you can test for the + presence of this name via `#ifdef' statements. + +`virtual void LexerOutput( const char* buf, int size )' + writes out `size' characters from the buffer `buf', which, while + `NUL'-terminated, may also contain internal `NUL's if the + scanner's rules can match text with `NUL's in them. + +`virtual void LexerError( const char* msg )' + reports a fatal error message. The default version of this + function writes the message to the stream `cerr' and exits. + + Note that a `yyFlexLexer' object contains its _entire_ scanning +state. Thus you can use such objects to create reentrant scanners, but +see also *Note Reentrant::. You can instantiate multiple instances of +the same `yyFlexLexer' class, and you can also combine multiple C++ +scanner classes together in the same program using the `-P' option +discussed above. + + Finally, note that the `%array' feature is not available to C++ +scanner classes; you must use `%pointer' (the default). + + Here is an example of a simple C++ scanner: + + + // An example of using the flex C++ scanner class. + + %{ + int mylineno = 0; + %} + + string \"[^\n"]+\" + + ws [ \t]+ + + alpha [A-Za-z] + dig [0-9] + name ({alpha}|{dig}|\$)({alpha}|{dig}|[_.\-/$])* + num1 [-+]?{dig}+\.?([eE][-+]?{dig}+)? + num2 [-+]?{dig}*\.{dig}+([eE][-+]?{dig}+)? + number {num1}|{num2} + + %% + + {ws} /* skip blanks and tabs */ + + "/*" { + int c; + + while((c = yyinput()) != 0) + { + if(c == '\n') + ++mylineno; + + else if(c == @samp{*}) + { + if((c = yyinput()) == '/') + break; + else + unput(c); + } + } + } + + {number} cout "number " YYText() '\n'; + + \n mylineno++; + + {name} cout "name " YYText() '\n'; + + {string} cout "string " YYText() '\n'; + + %% + + int main( int /* argc */, char** /* argv */ ) + { + @code{flex}Lexer* lexer = new yyFlexLexer; + while(lexer->yylex() != 0) + ; + return 0; + } + + If you want to create multiple (different) lexer classes, you use the +`-P' flag (or the `prefix=' option) to rename each `yyFlexLexer' to +some other `xxFlexLexer'. You then can include `' in your +other sources once per lexer class, first renaming `yyFlexLexer' as +follows: + + + #undef yyFlexLexer + #define yyFlexLexer xxFlexLexer + #include + + #undef yyFlexLexer + #define yyFlexLexer zzFlexLexer + #include + + if, for example, you used `%option prefix="xx"' for one of your +scanners and `%option prefix="zz"' for the other. + + +File: flex.info, Node: Reentrant, Next: Lex and Posix, Prev: Cxx, Up: Top + +19 Reentrant C Scanners +*********************** + +`flex' has the ability to generate a reentrant C scanner.

Had this option not been specified, `flex' +would have happily generated a non-reentrant scanner without +complaining.

Here are the declarations of `yy_push_state' and +`yy_pop_state' in the reentrant scanner: + + + static void yy_push_state ( int new_state , yyscan_t yyscanner ) ; + static void yy_pop_state ( yyscan_t yyscanner ) ; + + Notice that the argument `yyscanner' appears in the declaration of +both functions. In fact, all `flex' functions in a reentrant scanner +have this additional argument. It is always the last argument in the +argument list, it is always of type `yyscan_t' (which is typedef'd to +`void *') and it is always named `yyscanner'. As you may have guessed, +`yyscanner' is a pointer to an opaque data structure encapsulating the +current state of the scanner. For a list of function declarations, see +*Note Reentrant Functions::.

These are macros that will expand to their equivalent lvalue. +All of the familiar `flex' globals have been replaced by their macro +equivalents. In particular, `yytext', `yyleng', `yylineno', `yyin', +`yyout', `yyextra', `yylval', and `yylloc' are macros. You may safely +use these macros in actions as if they were plain variables. We only +tell you this so you don't expect to link to these variables +externally. Currently, each macro expands to a member of an internal +struct, e.g., + + + #define yytext (((struct yyguts_t*)yyscanner)->yytext_r) + + One important thing to remember about `yytext' and friends is that +`yytext' is not a global variable in a reentrant scanner, you can not +access it directly from outside an action or from other functions. You +must use an accessor method, e.g., `yyget_text', to accomplish this. +(See below). + + +File: flex.info, Node: Init and Destroy Functions, Next: Accessor Methods, Prev: Global Replacement, Up: Reentrant Detail + +19.4.4 Init and Destroy Functions +--------------------------------- + +`yylex_init' and `yylex_destroy' must be called before and after +`yylex', respectively. + + + int yylex_init ( yyscan_t * ptr_yy_globals ) ; + int yylex_init_extra ( YY_EXTRA_TYPE user_defined, yyscan_t * ptr_yy_globals ) ; + int yylex ( yyscan_t yyscanner ) ; + int yylex_destroy ( yyscan_t yyscanner ) ; + + The function `yylex_init' must be called before calling any other +function. The argument to `yylex_init' is the address of an +uninitialized pointer to be filled in by `yylex_init', overwriting any +previous contents. The function `yylex_init_extra' may be used instead, +taking as its first argument a variable of type `YY_EXTRA_TYPE'. See +the section on yyextra, below, for more details. + + The value stored in `ptr_yy_globals' should thereafter be passed to +`yylex' and `yylex_destroy'. Flex does not save the argument passed to +`yylex_init', so it is safe to pass the address of a local pointer to +`yylex_init' so long as it remains in scope for the duration of all +calls to the scanner, up to and including the call to `yylex_destroy'. + + The function `yylex' should be familiar to you by now. The reentrant +version takes one argument, which is the value returned (via an +argument) by `yylex_init'. Otherwise, it behaves the same as the +non-reentrant version of `yylex'. + + Both `yylex_init' and `yylex_init_extra' returns 0 (zero) on success, +or non-zero on failure, in which case errno is set to one of the +following values: + + * ENOMEM Memory allocation error. *Note memory-management::. + + * EINVAL Invalid argument. + + The function `yylex_destroy' should be called to free resources used +by the scanner. After `yylex_destroy' is called, the contents of +`yyscanner' should not be used. Of course, there is no need to destroy +a scanner if you plan to reuse it. A `flex' scanner (both reentrant +and non-reentrant) may be restarted by calling `yyrestart'. + + Below is an example of a program that creates a scanner, uses it, +then destroys it when done: + + + int main () + { + yyscan_t scanner; + int tok; + + yylex_init(&scanner); + + while ((tok=yylex()) > 0) + printf("tok=%d yytext=%s\n", tok, yyget_text(scanner)); + + yylex_destroy(scanner); + return 0; + } + + +File: flex.info, Node: Accessor Methods, Next: Extra Data, Prev: Init and Destroy Functions, Up: Reentrant Detail + +19.4.5 Accessing Variables with Reentrant Scanners +-------------------------------------------------- + +Accessor methods (get/set functions) provide access to common `flex' +variables. + + Many scanners that you build will be part of a larger project. +Portions of your project will need access to `flex' values, such as +`yytext'. In a non-reentrant scanner, these values are global, so +there is no problem accessing them. However, in a reentrant scanner, +there are no global `flex' values. You can not access them directly. +Instead, you must access `flex' values using accessor methods (get/set +functions). Each accessor method is named `yyget_NAME' or `yyset_NAME', +where `NAME' is the name of the `flex' variable you want. For example: + + + /* Set the last character of yytext to NULL. */ + void chop ( yyscan_t scanner ) + { + int len = yyget_leng( scanner ); + yyget_text( scanner )[len - 1] = '\0'; + } + + The above code may be called from within an action like this: + + + %% + .+\n { chop( yyscanner );} + + You may find that `%option header-file' is particularly useful for +generating prototypes of all the accessor functions. *Note +option-header::. + + +File: flex.info, Node: Extra Data, Next: About yyscan_t, Prev: Accessor Methods, Up: Reentrant Detail + +19.4.6 Extra Data +----------------- + +User-specific data can be stored in `yyextra'. + + In a reentrant scanner, it is unwise to use global variables to +communicate with or maintain state between different pieces of your +program. However, you may need access to external data or invoke +external functions from within the scanner actions. Likewise, you may +need to pass information to your scanner (e.g., open file descriptors, +or database connections). In a non-reentrant scanner, the only way to +do this would be through the use of global variables. `Flex' allows +you to store arbitrary, "extra" data in a scanner. This data is +accessible through the accessor methods `yyget_extra' and `yyset_extra' +from outside the scanner, and through the shortcut macro `yyextra' from +within the scanner itself. They are defined as follows: + + + #define YY_EXTRA_TYPE void* + YY_EXTRA_TYPE yyget_extra ( yyscan_t scanner ); + void yyset_extra ( YY_EXTRA_TYPE arbitrary_data , yyscan_t scanner); + + In addition, an extra form of `yylex_init' is provided, +`yylex_init_extra'. This function is provided so that the yyextra value +can be accessed from within the very first yyalloc, used to allocate +the scanner itself. + + By default, `YY_EXTRA_TYPE' is defined as type `void *'.

In this section +we discuss all of the known areas of incompatibility between `flex', +AT&T `lex', and the POSIX specification. `flex''s `-l' option turns on +maximum compatibility with the original AT&T `lex' implementation, at +the cost of a major loss in the generated scanner's performance. We +note below which incompatibilities can be overcome using the `-l' +option. `flex' is fully compatible with `lex' with the following +exceptions: + + * The undocumented `lex' scanner internal variable `yylineno' is not + supported unless `-l' or `%option yylineno' is used. + + * `yylineno' should be maintained on a per-buffer basis, rather than + a per-scanner (single global variable) basis. + + * `yylineno' is not part of the POSIX specification. + + * The `input()' routine is not redefinable, though it may be called + to read characters following whatever has been matched by a rule. + If `input()' encounters an end-of-file the normal `yywrap()' + processing is done. A "real" end-of-file is returned by `input()' + as `EOF'. + + * Input is instead controlled by defining the `YY_INPUT()' macro. + + * The `flex' restriction that `input()' cannot be redefined is in + accordance with the POSIX specification, which simply does not + specify any way of controlling the scanner's input other than by + making an initial assignment to `yyin'. + + * The `unput()' routine is not redefinable. This restriction is in + accordance with POSIX. + + * `flex' scanners are not as reentrant as `lex' scanners. In + particular, if you have an interactive scanner and an interrupt + handler which long-jumps out of the scanner, and the scanner is + subsequently called again, you may get the following message: + + + fatal @code{flex} scanner internal error--end of buffer missed + + To reenter the scanner, first use: + + + yyrestart( yyin ); + + Note that this call will throw away any buffered input; usually + this isn't a problem with an interactive scanner. *Note + Reentrant::, for `flex''s reentrant API. + + * Also note that `flex' C++ scanner classes _are_ reentrant, so if + using C++ is an option for you, you should use them instead. + *Note Cxx::, and *Note Reentrant:: for details. + + * `output()' is not supported. Output from the ECHO macro is done + to the file-pointer `yyout' (default `stdout)'. + + * `output()' is not part of the POSIX specification. + + * `lex' does not support exclusive start conditions (%x), though they + are in the POSIX specification. + + * When definitions are expanded, `flex' encloses them in parentheses. + With `lex', the following: + + + NAME [A-Z][A-Z0-9]* + %% + foo{NAME}? printf( "Found it\n" ); + %% + + will not match the string `foo' because when the macro is expanded + the rule is equivalent to `foo[A-Z][A-Z0-9]*?' and the precedence + is such that the `?' is associated with `[A-Z0-9]*'. With `flex', + the rule will be expanded to `foo([A-Z][A-Z0-9]*)?' and so the + string `foo' will match. + + * Note that if the definition begins with `^' or ends with `$' then + it is _not_ expanded with parentheses, to allow these operators to + appear in definitions without losing their special meanings. But + the `', `/', and `<>' operators cannot be used in a `flex' + definition. + + * Using `-l' results in the `lex' behavior of no parentheses around + the definition. + + * The POSIX specification is that the definition be enclosed in + parentheses. + + * Some implementations of `lex' allow a rule's action to begin on a + separate line, if the rule's pattern has trailing whitespace: + + + %% + foo|bar + { foobar_action();} + + `flex' does not support this feature. + + * The `lex' `%r' (generate a Ratfor scanner) option is not + supported. It is not part of the POSIX specification. + + * After a call to `unput()', _yytext_ is undefined until the next + token is matched, unless the scanner was built using `%array'. + This is not the case with `lex' or the POSIX specification. The + `-l' option does away with this incompatibility. + + * The precedence of the `{,}' (numeric range) operator is different. + The AT&T and POSIX specifications of `lex' interpret `abc{1,3}' + as match one, two, or three occurrences of `abc'", whereas `flex' + interprets it as "match `ab' followed by one, two, or three + occurrences of `c'". The `-l' and `--posix' options do away with + this incompatibility. + + * The precedence of the `^' operator is different. `lex' interprets + `^foo|bar' as "match either 'foo' at the beginning of a line, or + 'bar' anywhere", whereas `flex' interprets it as "match either + `foo' or `bar' if they come at the beginning of a line". The + latter is in agreement with the POSIX specification. + + * The special table-size declarations such as `%a' supported by + `lex' are not required by `flex' scanners.. `flex' ignores them. + + * The name `FLEX_SCANNER' is `#define''d so scanners may be written + for use with either `flex' or `lex'. Scanners also include + `YY_FLEX_MAJOR_VERSION', `YY_FLEX_MINOR_VERSION' and + `YY_FLEX_SUBMINOR_VERSION' indicating which version of `flex' + generated the scanner. For example, for the 2.5.22 release, these + defines would be 2, 5 and 22 respectively. If the version of + `flex' being used is a beta version, then the symbol `FLEX_BETA' + is defined. + + * The symbols `[[' and `]]' in the code sections of the input may + conflict with the m4 delimiters. *Note M4 Dependency::. + + + The following `flex' features are not included in `lex' or the POSIX +specification: + + * C++ scanners + + * %option + + * start condition scopes + + * start condition stacks + + * interactive/non-interactive scanners + + * yy_scan_string() and friends + + * yyterminate() + + * yy_set_interactive() + + * yy_set_bol() + + * YY_AT_BOL() <> + + * <*> + + * YY_DECL + + * YY_START + + * YY_USER_ACTION + + * YY_USER_INIT + + * #line directives + + * %{}'s around actions + + * reentrant C API + + * multiple actions on a line + + * almost all of the `flex' command-line options + + The feature "multiple actions on a line" refers to the fact that +with `flex' you can put multiple actions on the same line, separated +with semi-colons, while with `lex', the following: + + + foo handle_foo(); ++num_foos_seen; + + is (rather surprisingly) truncated to + + + foo handle_foo(); + + `flex' does not truncate the action.

Initialization takes place during +the first call to yylex(). Thereafter, flex may reallocate more memory +if it needs to enlarge a buffer. As of version 2.5.9 Flex will clean up +all memory when you call `yylex_destroy' *Note faq-memory-leak::. + + Flex allocates dynamic memory for four purposes, listed below (1) + +16kB for the input buffer. + Flex allocates memory for the character buffer used to perform + pattern matching. Flex must read ahead from the input stream and + store it in a large character buffer. This buffer is typically + the largest chunk of dynamic memory flex consumes. This buffer + will grow if necessary, doubling the size each time. Flex frees + this memory when you call yylex_destroy(). The default size of + this buffer (16384 bytes) is almost always too large. The ideal + size for this buffer is the length of the longest token expected, + in bytes, plus a little more. Flex will allocate a few extra + bytes for housekeeping. Currently, to override the size of the + input buffer you must `#define YY_BUF_SIZE' to whatever number of + bytes you want. We don't plan to change this in the near future, + but we reserve the right to do so if we ever add a more robust + memory management API. + +64kb for the REJECT state. This will only be allocated if you use REJECT. + The size is the large enough to hold the same number of states as + characters in the input buffer. If you override the size of the + input buffer (via `YY_BUF_SIZE'), then you automatically override + the size of this buffer as well. + +100 bytes for the start condition stack. + Flex allocates memory for the start condition stack. This is the + stack used for pushing start states, i.e., with yy_push_state(). + It will grow if necessary. Since the states are simply integers, + this stack doesn't consume much memory. This stack is not present + if `%option stack' is not specified. You will rarely need to tune + this buffer. The ideal size for this stack is the maximum depth + expected. The memory for this stack is automatically destroyed + when you call yylex_destroy(). *Note option-stack::. + +40 bytes for each YY_BUFFER_STATE. + Flex allocates memory for each YY_BUFFER_STATE. The buffer state + itself is about 40 bytes, plus an additional large character + buffer (described above.) The initial buffer state is created + during initialization, and with each call to yy_create_buffer(). + You can't tune the size of this, but you can tune the character + buffer as described above. Any buffer state that you explicitly + create by calling yy_create_buffer() is _NOT_ destroyed + automatically. You must call yy_delete_buffer() to free the + memory. The exception to this rule is that flex will delete the + current buffer automatically when you call yylex_destroy(). If you + delete the current buffer, be sure to set it to NULL. That way, + flex will not try to delete the buffer a second time (possibly + crashing your program!) At the time of this writing, flex does not + provide a growable stack for the buffer states. You have to + manage that yourself. *Note Multiple Input Buffers::. + +84 bytes for the reentrant scanner guts + Flex allocates about 84 bytes for the reentrant scanner structure + when you call yylex_init().

By default, these functions are +wrappers around the standard C functions, `malloc', `realloc', and +`free', respectively. You can override the default implementations by +telling flex that you will provide your own implementations. + + To override the default implementations, you must do two things: + + 1. Suppress the default implementations by specifying one or more of + the following options: + + * `%option noyyalloc' + + * `%option noyyrealloc' + + * `%option noyyfree'. + + 2.

The string itself is part of the input +buffer, and is _NOT_ allocated separately. The value of yytext will be +overwritten the next time yylex() is called. In short, the value of +yytext is only valid from within the matched rule's action. + + Often, you want the value of yytext to persist for later processing, +i.e., by a parser with non-zero lookahead. In order to preserve yytext, +you will have to copy it with strdup() or a similar function. But this +introduces some headache because your parser is now responsible for +freeing the copy of yytext. If you use a yacc or bison parser, +(commonly used with flex), you will discover that the error recovery +mechanisms can cause memory to be leaked. + + To prevent memory leaks from strdup'd yytext, you will have to track +the memory somehow. Our experience has shown that a garbage collection +mechanism or a pooled memory mechanism will save you a lot of grief +when writing parsers. + + +File: flex.info, Node: Serialized Tables, Next: Diagnostics, Prev: Memory Management, Up: Top + +22 Serialized Tables +******************** + +A `flex' scanner has the ability to save the DFA tables to a file, and +load them at runtime when needed. The motivation for this feature is +to reduce the runtime memory footprint. Traditionally, these tables +have been compiled into the scanner as C arrays, and are sometimes +quite large. Since the tables are compiled into the scanner, the +memory used by the tables can never be freed. This is a waste of +memory, especially if an application uses several scanners, but none of +them at the same time. + + The serialization feature allows the tables to be loaded at runtime, +before scanning begins. The tables may be discarded when scanning is +finished. + +* Menu: + +* Creating Serialized Tables:: +* Loading and Unloading Serialized Tables:: +* Tables File Format:: + + +File: flex.info, Node: Creating Serialized Tables, Next: Loading and Unloading Serialized Tables, Prev: Serialized Tables, Up: Serialized Tables + +22.1 Creating Serialized Tables +=============================== + +You may create a scanner with serialized tables by specifying: + + + %option tables-file=FILE + or + --tables-file=FILE + + These options instruct flex to save the DFA tables to the file FILE. +The tables will _not_ be embedded in the generated scanner. The scanner +will not function on its own. The scanner will be dependent upon the +serialized tables. You must load the tables from this file at runtime +before you can scan anything. + + If you do not specify a filename to `--tables-file', the tables will +be saved to `lex.yy.tables', where `yy' is the appropriate prefix. + + If your project uses several different scanners, you can concatenate +the serialized tables into one file, and flex will find the correct set +of tables, using the scanner prefix as part of the lookup key. An +example follows: + + + $ flex --tables-file --prefix=cpp cpp.l + $ flex --tables-file --prefix=c c.l + $ cat lex.cpp.tables lex.c.tables > all.tables + + The above example created two scanners, `cpp', and `c'. Since we did +not specify a filename, the tables were serialized to `lex.c.tables' and +`lex.cpp.tables', respectively. Then, we concatenated the two files +together into `all.tables', which we will distribute with our project. +At runtime, we will open the file and tell flex to load the tables from +it. Flex will find the correct tables automatically. (See next +section). + + +File: flex.info, Node: Loading and Unloading Serialized Tables, Next: Tables File Format, Prev: Creating Serialized Tables, Up: Serialized Tables + +22.2 Loading and Unloading Serialized Tables +============================================ + +If you've built your scanner with `%option tables-file', then you must +load the scanner tables at runtime. This can be accomplished with the +following function: + + -- Function: int yytables_fload (FILE* FP [, yyscan_t SCANNER]) + Locates scanner tables in the stream pointed to by FP and loads + them. Memory for the tables is allocated via `yyalloc'. You must + call this function before the first call to `yylex'. The argument + SCANNER only appears in the reentrant scanner. This function + returns `0' (zero) on success, or non-zero on error. + + The loaded tables are *not* automatically destroyed (unloaded) when +you call `yylex_destroy'. The reason is that you may create several +scanners of the same type (in a reentrant scanner), each of which needs +access to these tables. To avoid a nasty memory leak, you must call +the following function: + + -- Function: int yytables_destroy ([yyscan_t SCANNER]) + Unloads the scanner tables. The tables must be loaded again before + you can scan any more data. The argument SCANNER only appears in + the reentrant scanner. This function returns `0' (zero) on + success, or non-zero on error. + + *The functions `yytables_fload' and `yytables_destroy' are not +thread-safe.* You must ensure that these functions are called exactly +once (for each scanner type) in a threaded program, before any thread +calls `yylex'. After the tables are loaded, they are never written to, +and no thread protection is required thereafter - until you destroy +them. + + +File: flex.info, Node: Tables File Format, Prev: Loading and Unloading Serialized Tables, Up: Serialized Tables + +22.3 Tables File Format +======================= + +This section defines the file format of serialized `flex' tables. + + The tables format allows for one or more sets of tables to be +specified, where each set corresponds to a given scanner. Scanners are +indexed by name, as described below. The file format is as follows: + + + TABLE SET 1 + +-------------------------------+ + Header | uint32 th_magic; | + | uint32 th_hsize; | + | uint32 th_ssize; | + | uint16 th_flags; | + | char th_version[]; | + | char th_name[]; | + | uint8 th_pad64[]; | + +-------------------------------+ + Table 1 | uint16 td_id; | + | uint16 td_flags; | + | uint32 td_lolen; | + | uint32 td_hilen; | + | void td_data[]; | + | uint8 td_pad64[]; | + +-------------------------------+ + Table 2 | | + . . . + . . . + . . . + . . . + Table n | | + +-------------------------------+ + TABLE SET 2 + . + . + . + TABLE SET N + + The above diagram shows that a complete set of tables consists of a +header followed by multiple individual tables. Furthermore, multiple +complete sets may be present in the same file, each set with its own +header and tables. The sets are contiguous in the file. The only way to +know if another set follows is to check the next four bytes for the +magic number (or check for EOF). The header and tables sections are +padded to 64-bit boundaries. Below we describe each field in detail. +This format does not specify how the scanner will expand the given +data, i.e., data may be serialized as int8, but expanded to an int32 +array at runtime. This is to reduce the size of the serialized data +where possible. Remember, _all integer values are in network byte +order_. + +Fields of a table header: + +`th_magic' + Magic number, always 0xF13C57B1. + +`th_hsize' + Size of this entire header, in bytes, including all fields plus + any padding. + +`th_ssize' + Size of this entire set, in bytes, including the header, all + tables, plus any padding. + +`th_flags' + Bit flags for this table set. Currently unused. + +`th_version[]' + Flex version in NULL-terminated string format. e.g., `2.5.13a'. + This is the version of flex that was used to create the serialized + tables. + +`th_name[]' + Contains the name of this table set.

We count on the fact that the `yy_transition' array + has already been seen. + + `YYTD_STRUCT (0x10)' + The data is a list of yy_trans_info structs, each of which + consists of two integers. There is no padding between struct + elements or between structs. The type of each member is + determined by the `YYTD_DATA*' bits. + +`td_lolen' + Specifies the number of elements in the lowest dimension array. If + this is a one-dimensional array, then it is simply the number of + elements in this array. The element size is determined by the + `td_flags' field. + +`td_hilen' + If `td_hilen' is non-zero, then the data is a two-dimensional + array. Otherwise, the data is a one-dimensional array. `td_hilen' + contains the number of elements in the higher dimensional array, + and `td_lolen' contains the number of elements in the lowest + dimension. + + Conceptually, `td_data' is either `sometype td_data[td_lolen]', or + `sometype td_data[td_hilen][td_lolen]', where `sometype' is + specified by the `td_flags' field. It is possible for both + `td_lolen' and `td_hilen' to be zero, in which case `td_data' is a + zero length array, and no data is loaded, i.e., this table is + simply skipped.

For example, in the following `foo' + cannot be matched because it comes after an identifier "catch-all" + rule: + + + [a-z]+ got_identifier(); + foo got_foo(); + + Using `REJECT' in a scanner suppresses this warning. + + * `warning, -s option given but default rule can be matched' means + that it is possible (perhaps only in a particular start condition) + that the default rule (match any single character) is the only one + that will match a particular input. Since `-s' was given, + presumably this is not intended. + + * `reject_used_but_not_detected undefined' or + `yymore_used_but_not_detected undefined'. These errors can occur + at compile time. They indicate that the scanner uses `REJECT' or + `yymore()' but that `flex' failed to notice the fact, meaning that + `flex' scanned the first two sections looking for occurrences of + these actions and failed to find any, but somehow you snuck some in + (via a #include file, for example). Use `%option reject' or + `%option yymore' to indicate to `flex' that you really do use + these features. + + * `flex scanner jammed'. a scanner compiled with `-s' has + encountered an input string which wasn't matched by any of its + rules. This error can also occur due to internal problems. + + * `token too large, exceeds YYLMAX'. your scanner uses `%array' and + one of its rules matched a string longer than the `YYLMAX' + constant (8K bytes by default). You can increase the value by + #define'ing `YYLMAX' in the definitions section of your `flex' + input. + + * `scanner requires -8 flag to use the character 'x''. Your scanner + specification includes recognizing the 8-bit character `'x'' and + you did not specify the -8 flag, and your scanner defaulted to + 7-bit because you used the `-Cf' or `-CF' table compression + options. See the discussion of the `-7' flag, *Note Scanner + Options::, for details. + + * `flex scanner push-back overflow'. you used `unput()' to push back + so much text that the scanner's buffer could not hold both the + pushed-back text and the current token in `yytext'. Ideally the + scanner should dynamically resize the buffer in this case, but at + present it does not. + + * `input buffer overflow, can't enlarge buffer because scanner uses + REJECT'. the scanner was working on matching an extremely large + token and needed to expand the input buffer. This doesn't work + with scanners that use `REJECT'. + + * `fatal flex scanner internal error--end of buffer missed'. This can + occur in a scanner which is reentered after a long-jump has jumped + out (or over) the scanner's activation frame. Before reentering + the scanner, use: + + yyrestart( yyin ); + or, as noted above, switch to using the C++ scanner class. + + * `too many start conditions in <> construct!' you listed more start + conditions in a <> construct than exist (so you must have listed at + least one of them twice). + + +File: flex.info, Node: Limitations, Next: Bibliography, Prev: Diagnostics, Up: Top + +24 Limitations +************** + +Some trailing context patterns cannot be properly matched and generate +warning messages (`dangerous trailing context'). These are patterns +where the ending of the first part of the rule matches the beginning of +the second part, such as `zx*/xy*', where the 'x*' matches the 'x' at +the beginning of the trailing context. (Note that the POSIX draft +states that the text matched by such patterns is undefined.) For some +trailing context rules, parts which are actually fixed-length are not +recognized as such, leading to the abovementioned performance loss. In +particular, parts using `|' or `{n}' (such as `foo{3}') are always +considered variable-length. Combining trailing context with the +special `|' action can result in _fixed_ trailing context being turned +into the more expensive _variable_ trailing context. For example, in +the following: + + + %% + abc | + xyz/def + + Use of `unput()' invalidates yytext and yyleng, unless the `%array' +directive or the `-l' option has been used. Pattern-matching of `NUL's +is substantially slower than matching other characters. Dynamic +resizing of the input buffer is slow, as it entails rescanning all the +text matched so far by the current (generally huge) token. Due to both +buffering of input and read-ahead, you cannot intermix calls to +`' routines, such as, getchar(), with `flex' rules and expect +it to work. Call `input()' instead. The total table entries listed by +the `-v' flag excludes the number of table entries needed to determine +what rule has been matched.

If you try to +match strings with a single rule then you'll wind up having to rescan +the string anyway to find any escape sequences. + + Instead you can use exclusive start conditions and a set of rules, +one for matching non-escaped text, one for matching a single escape, +one for matching an embedded newline, and one for recognizing the end +of the string. Each of these rules is then faced with the question of +where to put its intermediary results. The best solution is for the +rules to append their local value of `yytext' to the end of a "string +literal" buffer. A rule like the escape-matcher will append to the +buffer the meaning of the escape sequence rather than the literal text +in `yytext'. In this way, `yytext' does not need to be modified at all. + + +File: flex.info, Node: Why do flex scanners call fileno if it is not ANSI compatible?, Next: Does flex support recursive pattern definitions?, Prev: How do I expand backslash-escape sequences in C-style quoted strings?, Up: FAQ + +Why do flex scanners call fileno if it is not ANSI compatible? +============================================================== + +Flex scanners call `fileno()' in order to get the file descriptor +corresponding to `yyin'. The file descriptor may be passed to +`isatty()' or `read()', depending upon which `%options' you specified. +If your system does not have `fileno()' support, to get rid of the +`read()' call, do not specify `%option read'. To get rid of the +`isatty()' call, you must specify one of `%option always-interactive' or +`%option never-interactive'. + + +File: flex.info, Node: Does flex support recursive pattern definitions?, Next: How do I skip huge chunks of input (tens of megabytes) while using flex?, Prev: Why do flex scanners call fileno if it is not ANSI compatible?, Up: FAQ + +Does flex support recursive pattern definitions? +================================================ + +e.g., + + + %% + block "{"({block}|{statement})*"}" + + No. You cannot have recursive definitions. The pattern-matching +power of regular expressions in general (and therefore flex scanners, +too) is limited. In particular, regular expressions cannot "balance" +parentheses to an arbitrary degree.

This is because `flex' uses an entirely +different matching technique ("deterministic finite automata") that +actually does all of the matching simultaneously, in parallel. (Seems +impossible, but it's actually a fairly simple technique once you +understand the principles.) + + A side-effect of this parallel matching is that when the input +matches more than one rule, `flex' scanners pick the rule that matched +the _most_ text. This is explained further in the manual, in the +section *Note Matching::. + + If you want `flex' to choose a shorter match, then you can work +around this behavior by expanding your short rule to match more text, +then put back the extra: + + + data_.* yyless( 5 ); BEGIN BLOCKIDSTATE; + + Another fix would be to make the second rule active only during the +`' start condition, and make that start condition +exclusive by declaring it with `%x' instead of `%s'. + + A final fix is to change the input language so that the ambiguity for +`data_' is removed, by adding characters to it that don't match the +identifier rule, or by removing characters (such as `_') from the +identifier rule so it no longer matches `data_'.

This means you +can safely use `select()' at the point and only call `yylex()' for +another token if `select()' indicates there's data available. + + That is, move the `select()' out from the input function to a point +where it determines whether `yylex()' gets called for the next token. + + With this approach, you will still have problems if your input can +arrive piecemeal; `select()' could inform you that the beginning of a +token is available, you call `yylex()' to get it, but it winds up +blocking waiting for the later characters in the token. + + Here's another way: Move your input multiplexing inside of +`YY_INPUT'. That is, whenever `YY_INPUT' is called, it `select()''s to +see where input is available. If input is available for the scanner, +it reads and returns the next byte. If input is available from another +source, it calls whatever function is responsible for reading from that +source. (If no input is available, it blocks until some input is +available.)

The reason is +that `flex' block-buffers the input it reads from `yyin'. This means +that the "outermost" `yylex()', when called, will automatically slurp +up the first 8K of input available on yyin, and subsequent calls to +other `yylex()''s won't see that input. You might be tempted to work +around this problem by redefining `YY_INPUT' to only return a small +amount of text, but it turns out that that approach is quite difficult. +Instead, the best solution is to combine all of your scanners into one +large scanner, using a different exclusive start condition for each. + + +File: flex.info, Node: How can I match text only at the end of a file?, Next: How can I make REJECT cascade across start condition boundaries?, Prev: Can I build nested parsers that work with the same input file?, Up: FAQ + +How can I match text only at the end of a file? +=============================================== + +There is no way to write a rule which is "match this text, but only if +it comes at the end of the file". You can fake it, though, if you +happen to have a character lying around that you don't allow in your +input. Then you redefine `YY_INPUT' to call your own routine which, if +it sees an `EOF', returns the magic character first (and remembers to +return a real `EOF' next time it's called).

It has to do +with how the scanner detects that it must be finished scanning a token. +For interactive scanners, after scanning each character the current +state is looked up in a table (essentially) to see whether there's a +chance of another input character possibly extending the length of the +match. If not, the scanner halts. For non-interactive scanners, the +end-of-token test is much simpler, basically a compare with 0, so no +memory bus cycles. Since the test occurs in the innermost scanning +loop, one would like to make it go as fast as possible. + + Still, it seems reasonable to allow the user to choose to trade off +a bit of performance in this area to gain the corresponding +flexibility.

Better is to either introduce a separate parser, or to +split the scanner into multiple scanners using (exclusive) start +conditions. + + You might have a separate start state once you've seen the `BEGIN'. +In that state, you might then have a regex that will match `END' (to +kick you out of the state), and perhaps `(.|\n)' to get a single +character within the chunk ... + + This approach also has much better error-reporting properties. + + +File: flex.info, Node: Memory leak - 16386 bytes allocated by malloc., Next: How do I track the byte offset for lseek()?, Prev: Why doesn't flex have non-greedy operators like perl does?, Up: FAQ + +Memory leak - 16386 bytes allocated by malloc. +============================================== + +UPDATED 2002-07-10: As of `flex' version 2.5.9, this leak means that +you did not call `yylex_destroy()'.

That is, (8192 * 2 + 2) for the +read-buffer, and about 40 for `struct yy_buffer_state' (depending upon +alignment). The leak is in the non-reentrant C scanner only (NOT in the +reentrant scanner, NOT in the C++ scanner). Since `flex' doesn't know +when you are done, the buffer is never freed. + + However, the leak won't multiply since the buffer is reused no +matter how many times you call `yylex()'. + + If you want to reclaim the memory when you are completely done +scanning, then you might try this: + + + /* For non-reentrant C scanner only. */ + yy_delete_buffer(YY_CURRENT_BUFFER); + yy_init = 1; + + Note: `yy_init' is an "internal variable", and hasn't been tested in +this situation.

The first is that +it's possible that `flex' will request less than `YY_READ_BUF_SIZE' +during an invocation of `YY_INPUT' (or that your input source will +return less even though `YY_READ_BUF_SIZE' bytes were requested). The +second problem is that when refilling its internal buffer, `flex' keeps +some characters from the previous buffer (because usually it's in the +middle of a match, and needs those characters to construct `yytext' for +the match once it's done). Because of this, `yy_c_buf_p - +YY_CURRENT_BUFFER->yy_ch_buf' won't be exactly the number of characters +already read from the current buffer. + + An alternative solution is to count the number of characters you've +matched since starting to scan.

When using +`flex', however, the `.l' files are the sources, and the generated `.c' +files (along with the `.o' files) are the intermediate files. This +requires you to carefully plan your Makefile. + + Modern `make' programs understand that `foo.l' is intended to +generate `lex.yy.c' or `foo.c', and will behave accordingly(1)(2). The +following Makefile does not explicitly instruct `make' how to build +`foo.c' from `foo.l'. Instead, it relies on the implicit rules of the +`make' program to build the intermediate file, `scan.c': + + + # Basic Makefile -- relies on implicit rules + # Creates "myprogram" from "scan.l" and "myprogram.c" + # + LEX=flex + myprogram: scan.o myprogram.o + scan.o: scan.l + + For simple cases, the above may be sufficient. For other cases, you +may have to explicitly instruct `make' how to build your scanner. The +following is an example of a Makefile containing explicit rules: + + + # Basic Makefile -- provides explicit rules + # Creates "myprogram" from "scan.l" and "myprogram.c" + # + LEX=flex + myprogram: scan.o myprogram.o + $(CC) -o $@ $(LDFLAGS) $^ + + myprogram.o: myprogram.c + $(CC) $(CPPFLAGS) $(CFLAGS) -o $@ -c $^ + + scan.o: scan.c + $(CC) $(CPPFLAGS) $(CFLAGS) -o $@ -c $^ + + scan.c: scan.l + $(LEX) $(LFLAGS) -o $@ $^ + + clean: + $(RM) *.o scan.c + + Notice in the above example that `scan.c' is in the `clean' target. +This is because we consider the file `scan.c' to be an intermediate +file. + + Finally, we provide a realistic example of a `flex' scanner used +with a `bison' parser(3). There is a tricky problem we have to deal +with. Since a `flex' scanner will typically include a header file +(e.g., `y.tab.h') generated by the parser, we need to be sure that the +header file is generated BEFORE the scanner is compiled. We handle this +case in the following example: + + + # Makefile example -- scanner and parser. + # Creates "myprogram" from "scan.l", "parse.y", and "myprogram.c" + # + LEX = flex + YACC = bison -y + YFLAGS = -d + objects = scan.o parse.o myprogram.o + + myprogram: $(objects) + scan.o: scan.l parse.c + parse.o: parse.y + myprogram.o: myprogram.c + + In the above example, notice the line, + + + scan.o: scan.l parse.c + + , which lists the file `parse.c' (the generated parser) as a +dependency of `scan.o'. We want to ensure that the parser is created +before the scanner is compiled, and the above line seems to do the +trick. Feel free to experiment with your specific implementation of +`make'. + + For more details on writing Makefiles, see *Note Top: (make)Top. + + ---------- Footnotes ---------- + + (1) GNU `make' and GNU `automake' are two such programs that provide +implicit rules for flex-generated scanners. + + (2) GNU `automake' may generate code to execute flex in +lex-compatible mode, or to stdout. If this is not what you want, then +you should provide an explicit rule in your Makefile.am + + (3) This example also applies to yacc parsers. + + +File: flex.info, Node: Bison Bridge, Next: M4 Dependency, Prev: Makefiles and Flex, Up: Appendices + +A.2 C Scanners with Bison Parsers +================================= + +This section describes the `flex' features useful when integrating +`flex' with `GNU bison'(1). Skip this section if you are not using +`bison' with your scanner. Here we discuss only the `flex' half of the +`flex' and `bison' pair. We do not discuss `bison' in any detail. For +more information about generating `bison' parsers, see *Note Top: +(bison)Top. + + A compatible `bison' scanner is generated by declaring `%option +bison-bridge' or by supplying `--bison-bridge' when invoking `flex' +from the command line. This instructs `flex' that the macro `yylval' +may be used. The data type for `yylval', `YYSTYPE', is typically +defined in a header file, included in section 1 of the `flex' input +file. For a list of functions and macros available, *Note +bison-functions::. + + The declaration of yylex becomes, + + + int yylex ( YYSTYPE * lvalp, yyscan_t scanner ); + + If `%option bison-locations' is specified, then the declaration +becomes, + + + int yylex ( YYSTYPE * lvalp, YYLTYPE * llocp, yyscan_t scanner ); + + Note that the macros `yylval' and `yylloc' evaluate to pointers. +Support for `yylloc' is optional in `bison', so it is optional in +`flex' as well.

We merely provide some glue +to ease development of your parser-scanner pair. + + +File: flex.info, Node: M4 Dependency, Next: Common Patterns, Prev: Bison Bridge, Up: Appendices + +A.3 M4 Dependency +================= + +The macro processor `m4'(1) must be installed wherever flex is +installed. `flex' invokes `m4', found by searching the directories in +the `PATH' environment variable. Any code you place in section 1 or in +the actions will be sent through m4. Please follow these rules to +protect your code from unwanted `m4' processing. + + * Do not use symbols that begin with, `m4_', such as, `m4_define', + or `m4_include', since those are reserved for `m4' macro names. If + for some reason you need m4_ as a prefix, use a preprocessor + #define to get your symbol past m4 unmangled. + + * Do not use the strings `[[' or `]]' anywhere in your code. The + former is not valid in C, except within comments and strings, but + the latter is valid in code such as `x[y[z]]'. The solution is + simple. To get the literal string `"]]"', use `"]""]"'. To get the + array notation `x[y[z]]', use `x[y[z] ]'. Flex will attempt to + detect these sequences in user code, and escape them. However, + it's best to avoid this complexity where possible, by removing + such sequences from your code. + + + `m4' is only required at the time you run `flex'. The generated +scanner is ordinary C or C++, and does _not_ require `m4'. + + ---------- Footnotes ---------- + + (1) The use of m4 is subject to change in future revisions of flex. +It is not part of the public API of flex. Do not depend on it. + + +File: flex.info, Node: Common Patterns, Prev: M4 Dependency, Up: Appendices + +A.4 Common Patterns +=================== + +This appendix provides examples of common regular expressions you might +use in your scanner. + +* Menu: + +* Numbers:: +* Identifiers:: +* Quoted Constructs:: +* Addresses:: + + +File: flex.info, Node: Numbers, Next: Identifiers, Up: Common Patterns + +A.4.1 Numbers +------------- + +C99 decimal constant + `([[:digit:]]{-}[0])[[:digit:]]*' + +C99 hexadecimal constant + `0[xX][[:xdigit:]]+' + +C99 octal constant + `0[0123456]*' + +C99 floating point constant + + {dseq} ([[:digit:]]+) + {dseq_opt} ([[:digit:]]*) + {frac} (({dseq_opt}"."{dseq})|{dseq}".") + {exp} ([eE][+-]?{dseq}) + {exp_opt} ({exp}?) + {fsuff} [flFL] + {fsuff_opt} ({fsuff}?) + {hpref} (0[xX]) + {hdseq} ([[:xdigit:]]+) + {hdseq_opt} ([[:xdigit:]]*) + {hfrac} (({hdseq_opt}"."{hdseq})|({hdseq}".")) + {bexp} ([pP][+-]?{dseq}) + {dfc} (({frac}{exp_opt}{fsuff_opt})|({dseq}{exp}{fsuff_opt})) + {hfc} (({hpref}{hfrac}{bexp}{fsuff_opt})|({hpref}{hdseq}{bexp}{fsuff_opt})) + + {c99_floating_point_constant} ({dfc}|{hfc}) + + See C99 section 6.4.4.2 for the gory details. + + + +File: flex.info, Node: Identifiers, Next: Quoted Constructs, Prev: Numbers, Up: Common Patterns + +A.4.2 Identifiers +----------------- + +C99 Identifier + + ucn ((\\u([[:xdigit:]]{4}))|(\\U([[:xdigit:]]{8}))) + nondigit [_[:alpha:]] + c99_id ([_[:alpha:]]|{ucn})([_[:alnum:]]|{ucn})* + + Technically, the above pattern does not encompass all possible C99 + identifiers, since C99 allows for "implementation-defined" + characters.

It has to do -with how the scanner detects that it must be finished scanning a token. -For interactive scanners, after scanning each character the current -state is looked up in a table (essentially) to see whether there's a -chance of another input character possibly extending the length of the -match. If not, the scanner halts. For non-interactive scanners, the -end-of-token test is much simpler, basically a compare with 0, so no -memory bus cycles. Since the test occurs in the innermost scanning -loop, one would like to make it go as fast as possible. - - Still, it seems reasonable to allow the user to choose to trade off -a bit of performance in this area to gain the corresponding -flexibility.

The second - pattern matches a single instance of `foo' or a single instance of - `bar' followed by one or more `r's, e.g., it matches the text - `barrrr' . - - * A `.' inside `[]''s just means a literal`.' (period), and NOT "any - character except newline". - - * Remember that `.' matches any character EXCEPT `\n' (and `EOF'). - If you really want to match ANY character, including newlines, - then use `(.|\n)' Beware that the regex `(.|\n)+' will match your - entire input! - - * Finally, if you want to match a literal `.'

It analyzes the input rules to construct equivalence classes for - those characters that always make the same transitions. It then - rewrites the NFA using equivalence classes for transitions instead - of characters. This cuts down the NFA->DFA computation time - dramatically, to the point where, for uncompressed DFA tables, the - DFA generation is often I/O bound in writing out the tables. - - 2. It maintains hash values for previously computed DFA states, so - testing whether a newly constructed DFA state is equivalent to a - previously constructed state can be done very quickly, by first - comparing hash values. - - -File: flex.info, Node: How can I use more than 8192 rules?, Next: How do I abandon a file in the middle of a scan and switch to a new file?, Prev: How does flex compile the DFA so quickly?, Up: FAQ - -How can I use more than 8192 rules? -=================================== - -`Flex' is compiled with an upper limit of 8192 rules per scanner. If -you need more than 8192 rules in your scanner, you'll have to recompile -`flex' with the following changes in `flexdef.h': - - - < #define YY_TRAILING_MASK 0x2000 - < #define YY_TRAILING_HEAD_MASK 0x4000 - -- - > #define YY_TRAILING_MASK 0x20000000 - > #define YY_TRAILING_HEAD_MASK 0x40000000 - - This should work okay as long as your C compiler uses 32 bit -integers.

When using -`flex', however, the `.l' files are the sources, and the generated `.c' -files (along with the `.o' files) are the intermediate files. This -requires you to carefully plan your Makefile. - - Modern `make' programs understand that `foo.l' is intended to -generate `lex.yy.c' or `foo.c', and will behave accordingly(1)(2). The -following Makefile does not explicitly instruct `make' how to build -`foo.c' from `foo.l'. Instead, it relies on the implicit rules of the -`make' program to build the intermediate file, `scan.c': - - - # Basic Makefile -- relies on implicit rules - # Creates "myprogram" from "scan.l" and "myprogram.c" - # - LEX=flex - myprogram: scan.o myprogram.o - scan.o: scan.l - - For simple cases, the above may be sufficient. For other cases, you -may have to explicitly instruct `make' how to build your scanner. The -following is an example of a Makefile containing explicit rules: - - - # Basic Makefile -- provides explicit rules - # Creates "myprogram" from "scan.l" and "myprogram.c" - # - LEX=flex - myprogram: scan.o myprogram.o - $(CC) -o $@ $(LDFLAGS) $^ - - myprogram.o: myprogram.c - $(CC) $(CPPFLAGS) $(CFLAGS) -o $@ -c $^ - - scan.o: scan.c - $(CC) $(CPPFLAGS) $(CFLAGS) -o $@ -c $^ - - scan.c: scan.l - $(LEX) $(LFLAGS) -o $@ $^ - - clean: - $(RM) *.o scan.c - - Notice in the above example that `scan.c' is in the `clean' target. -This is because we consider the file `scan.c' to be an intermediate -file. - - Finally, we provide a realistic example of a `flex' scanner used -with a `bison' parser(3). There is a tricky problem we have to deal -with. Since a `flex' scanner will typically include a header file -(e.g., `y.tab.h') generated by the parser, we need to be sure that the -header file is generated BEFORE the scanner is compiled. We handle this -case in the following example: - - - # Makefile example -- scanner and parser. - # Creates "myprogram" from "scan.l", "parse.y", and "myprogram.c" - # - LEX = flex - YACC = bison -y - YFLAGS = -d - objects = scan.o parse.o myprogram.o - - myprogram: $(objects) - scan.o: scan.l parse.c - parse.o: parse.y - myprogram.o: myprogram.c - - In the above example, notice the line, - - - scan.o: scan.l parse.c - - , which lists the file `parse.c' (the generated parser) as a -dependency of `scan.o'. We want to ensure that the parser is created -before the scanner is compiled, and the above line seems to do the -trick. Feel free to experiment with your specific implementation of -`make'. - - For more details on writing Makefiles, see *Note Top: (make)Top. - - ---------- Footnotes ---------- - - (1) GNU `make' and GNU `automake' are two such programs that provide -implicit rules for flex-generated scanners. - - (2) GNU `automake' may generate code to execute flex in -lex-compatible mode, or to stdout. If this is not what you want, then -you should provide an explicit rule in your Makefile.am - - (3) This example also applies to yacc parsers. - - -File: flex.info, Node: Bison Bridge, Next: M4 Dependency, Prev: Makefiles and Flex, Up: Appendices - -A.2 C Scanners with Bison Parsers -================================= - -This section describes the `flex' features useful when integrating -`flex' with `GNU bison'(1). Skip this section if you are not using -`bison' with your scanner. Here we discuss only the `flex' half of the -`flex' and `bison' pair. We do not discuss `bison' in any detail. For -more information about generating `bison' parsers, see *Note Top: -(bison)Top. - - A compatible `bison' scanner is generated by declaring `%option -bison-bridge' or by supplying `--bison-bridge' when invoking `flex' -from the command line. This instructs `flex' that the macro `yylval' -may be used. The data type for `yylval', `YYSTYPE', is typically -defined in a header file, included in section 1 of the `flex' input -file. For a list of functions and macros available, *Note -bison-functions::. - - The declaration of yylex becomes, - - - int yylex ( YYSTYPE * lvalp, yyscan_t scanner ); - - If `%option bison-locations' is specified, then the declaration -becomes, - - - int yylex ( YYSTYPE * lvalp, YYLTYPE * llocp, yyscan_t scanner ); - - Note that the macros `yylval' and `yylloc' evaluate to pointers. -Support for `yylloc' is optional in `bison', so it is optional in -`flex' as well. The following is an example of a `flex' scanner that is -compatible with `bison'. - - - /* Scanner for "C" assignment statements... sort of. */ - %{ - #include "y.tab.h" /* Generated by bison. */ - %} - - %option bison-bridge bison-locations - % - - [[:digit:]]+ { yylval->num = atoi(yytext); return NUMBER;} - [[:alnum:]]+ { yylval->str = strdup(yytext); return STRING;} - "="|";" { return yytext[0];} - . {} - % - - As you can see, there really is no magic here. We just use `yylval' -as we would any other variable. The data type of `yylval' is generated -by `bison', and included in the file `y.tab.h'. Here is the -corresponding `bison' parser: - - - /* Parser to convert "C" assignments to lisp. */ - %{ - /* Pass the argument to yyparse through to yylex. */ - #define YYPARSE_PARAM scanner - #define YYLEX_PARAM scanner - %} - %locations - %pure_parser - %union { - int num; - char* str; - } - %token STRING - %token NUMBER - %% - assignment: - STRING '=' NUMBER ';' { - printf( "(setf %s %d)", $1, $3 ); - } - ; - - ---------- Footnotes ---------- - - (1) The features described here are purely optional, and are by no -means the only way to use flex with bison. We merely provide some glue -to ease development of your parser-scanner pair. - - -File: flex.info, Node: M4 Dependency, Next: Common Patterns, Prev: Bison Bridge, Up: Appendices - -A.3 M4 Dependency -================= - -The macro processor `m4'(1) must be installed wherever flex is -installed. `flex' invokes `m4', found by searching the directories in -the `PATH' environment variable. Any code you place in section 1 or in -the actions will be sent through m4. Please follow these rules to -protect your code from unwanted `m4' processing. - - * Do not use symbols that begin with, `m4_', such as, `m4_define', - or `m4_include', since those are reserved for `m4' macro names. If - for some reason you need m4_ as a prefix, use a preprocessor - #define to get your symbol past m4 unmangled. - - * Do not use the strings `[[' or `]]' anywhere in your code. The - former is not valid in C, except within comments and strings, but - the latter is valid in code such as `x[y[z]]'. The solution is - simple. To get the literal string `"]]"', use `"]""]"'. To get the - array notation `x[y[z]]', use `x[y[z] ]'. Flex will attempt to - detect these sequences in user code, and escape them. However, - it's best to avoid this complexity where possible, by removing - such sequences from your code. - - - `m4' is only required at the time you run `flex'. The generated -scanner is ordinary C or C++, and does _not_ require `m4'. - - ---------- Footnotes ---------- - - (1) The use of m4 is subject to change in future revisions of flex. -It is not part of the public API of flex.
