@node Top
@top Autotyping

  Under certain circumstances you will find yourself typing similar things
over and over again.  This is especially true of form letters and programming
language constructs.  Project-specific header comments, flow-control
constructs or magic numbers are essentially the same every time.  Emacs has
various features for doing tedious and repetitive typing chores for you
in addition to the Abbrev features (@pxref{(emacs)Abbrevs}).

  One solution is using skeletons, flexible rules that say what to
insert, and how to do it.  Various programming language modes offer some
ready-to-use skeletons, and you can adapt them to suit your needs or
taste, or define new ones.

  Another feature is automatic insertion of what you want into empty files,
depending on the file-name or the mode as appropriate.  You can have a file or
a skeleton inserted, or you can call a function.  Then there is the
possibility to have Un*x interpreter scripts automatically take on a magic
number and be executable as soon as they are saved.  Or you can have a
copyright notice's year updated, if necessary, every time you save a
file.  Similarly for time stamps in the file.

  URLs can be inserted based on a word at point.  Flexible templates can
be defined for inserting and navigating between text more generally.  A
sort of meta-expansion facility can be used to try a set of alternative
completions and expansions of text at point.

@node Using Skeletons
@chapter Using Skeletons
@cindex skeletons
@cindex using skeletons

  When you want Emacs to insert a form letter or a typical construct of the
programming language you are using, skeletons are a means of accomplishing
this.  Normally skeletons each have a command of their own, that, when called,
will insert the skeleton.  These commands can be issued in the usual ways
(@pxref{(emacs)Commands}).  Modes that offer various skeletons will often
bind these to key-sequences on the @kbd{C-c} prefix, as well as having
an @cite{Insert} menu and maybe even predefined abbrevs for them
(@pxref{Skeletons as Abbrevs}).

  The simplest kind of skeleton will simply insert some text indented
according to the major mode and leave the cursor at a likely place in the
middle.  Interactive skeletons may prompt you for a string that will be part
of the inserted text.

  Skeletons may ask for input several times.  They even have a looping
mechanism in which you will be asked for input as long as you are willing to
furnish it.  An example would be multiple ``else if'' conditions.  You can
recognize this situation by a prompt ending in @key{RET}, @kbd{C-g}
or @kbd{C-h}.  This
means that entering an empty string will simply assume that you are finished.
Typing quit on the other hand terminates the loop but also the rest of the
skeleton, e.g. an ``else'' clause is skipped.  Only a syntactically necessary
termination still gets inserted.



@node Wrapping Skeletons
@chapter Wrapping Skeletons Around Existing Text
@cindex wrapping skeletons

  Often you will find yourself with some code that for whatever reason
suddenly becomes conditional.  Or you have written a bit of text and want to
put it in the middle of a form letter.  Skeletons provide a means for
accomplishing this, and can even, in the case of programming languages,
reindent the wrapped code for you.

  Skeleton commands take an optional numeric prefix argument
(@pxref{(emacs)Arguments}).  This is interpreted in two different ways depending
on whether the prefix is positive, i.e. forwards oriented or negative,
i.e. backwards oriented.

  A positive prefix means to wrap the skeleton around that many
following words.  This is accomplished by putting the words there where
the point is normally left after that skeleton is inserted (@pxref{Using
Skeletons}).  The point (@pxref{(emacs)Point}) is left at the next
interesting spot in the skeleton instead.

  A negative prefix means to do something similar with that many precedingly
marked interregions (@pxref{(emacs)Mark}).  In the simplest case, if you type
@kbd{M--} just before issuing the skeleton command, that will wrap the
skeleton around the current region, just like a positive argument would have
wrapped it around a number of words.

  Smaller negative arguments will wrap that many interregions into successive
interesting spots within the skeleton, again leaving the point at the next one.
We speak about interregions rather than regions here, because we treat them in
the order they appear in the buffer, which coincides with successive regions
only if they were marked in order.

  That is, if you marked in alphabetical order the points A B C [] (where []
represents the point) and call a skeleton command with @kbd{M-- 3}, you will
wrap the text from A to B into the first interesting spot of the skeleton, the
text from B to C into the next one, the text from C to the point into the
third one, and leave the point in the fourth one.  If there are less marks in
the buffer, or if the skeleton defines less interesting points, the surplus is
ignored.

  If, on the other hand, you marked in alphabetical order the points [] A C B,
and call a skeleton command with @kbd{M-- 3}, you will wrap the text from
point to A, then the text from A to C and finally the text from C to B.  This
is done because the regions overlap and Emacs would be helplessly lost if it
tried to follow the order in which you marked these points.



@node Skeletons as Abbrevs
@chapter Skeletons as Abbrev Expansions
@cindex skeletons as abbrevs

  Rather than use a key binding for every skeleton command, you can also
define an abbreviation (@pxref{(emacs)Defining Abbrevs}) that will expand
(@pxref{(emacs)Expanding Abbrevs}) into the skeleton.

  Say you want @samp{ifst} to be an abbreviation for the C language if
statement.  You will tell Emacs that @samp{ifst} expands to the empty string
and then calls the skeleton command.  In Emacs Lisp you can say something like
@code{(define-abbrev c-mode-abbrev-table "ifst" "" 'c-if)}.  Or you can edit
the output from @kbd{M-x list-abbrevs} to make it look like this:

@example
(c-mode-abbrev-table)
"if"	       0    ""	       c-if
@end example

@noindent
(Some blank lines of no semantic significance, and other abbrev tables,
have been omitted.)



@node Skeleton Language
@chapter Skeleton Language
@cindex skeleton language

@findex skeleton-insert
  Skeletons are an shorthand extension to the Lisp language, where various
atoms directly perform either actions on the current buffer or rudimentary
flow control mechanisms.  Skeletons are interpreted by the function
@code{skeleton-insert}.

  A skeleton is a list starting with an interactor, which is usually a
prompt-string, or @code{nil} when not needed, but can also be a Lisp
expression for complex read functions or for returning some calculated value.
The rest of the list are any number of elements as described in the following
table:

@table @asis
@item @code{"@var{string}"}, @code{?@var{c}}, @code{?\@var{c}}
@vindex skeleton-transformation
Insert string or character.  Literal strings and characters are passed through
@code{skeleton-transformation} when that is non-@code{nil}.
@item @code{?\n}
@c ??? something seems very wrong here.
Insert a newline and align under current line.  Use newline character
@code{?\n} to prevent alignment.
@item @code{_}
Interesting point.  When wrapping skeletons around successive regions, they are
put at these places.  Point is left at first @code{_} where nothing is wrapped.
@item @code{>}
Indent line according to major mode.  When following element is @code{_}, and
there is a interregion that will be wrapped here, indent that interregion.
@item @code{&}
Logical and.  Iff preceding element moved point, i.e. usually inserted
something, do following element.
@item @code{|}
Logical xor.  Iff preceding element didn't move point, i.e. usually inserted
nothing, do following element.
@item @code{-@var{number}}
Delete preceding number characters.  Depends on value of
@code{skeleton-untabify}.
@item @code{()} or @code{nil}
Ignored.
@item @var{lisp-expression}
Evaluated, and the return value is again interpreted as a skeleton element.
@item @code{str}
A special variable that, when evaluated the first time, usually prompts
for input according to the skeleton's interactor.  It is then set to the
return value resulting from the interactor.  Each subskeleton has its local
copy of this variable.
@item @code{v1}, @code{v2}
Skeleton-local user variables.
@item @code{'@var{expression}}
Evaluate following Lisp expression for its side-effect, but prevent it from
being interpreted as a skeleton element.
@item @var{skeleton}
Subskeletons are inserted recursively, not once, but as often as the user
enters something at the subskeletons interactor.  Thus there must be a
@code{str} in the subskeleton.  They can also be used non-interactively, when
prompt is a lisp-expression that returns successive list-elements.
@item @code{resume:}
Ignored.  Execution resumes here if the user quits during skeleton
interpretation.
@item @code{quit}
A constant which is non-@code{nil} when the @code{resume:} section was entered
because the user quit.
@end table

@findex skeleton-further-elements
  Some modes also use other skeleton elements they themselves defined.  For
example in shell script mode's skeletons you will find @code{<} which does a
rigid indentation backwards, or in CC mode's skeletons you find the
self-inserting elements @code{@{} and @code{@}}.  These are defined by the
buffer-local variable @code{skeleton-further-elements} which is a list of
variables bound while interpreting a skeleton.

@findex define-skeleton
  The macro @code{define-skeleton} defines a command for interpreting a
skeleton.  The first argument is the command name, the second is a
documentation string, and the rest is an interactor and any number of skeleton
elements together forming a skeleton.  This skeleton is assigned to a variable
of the same name as the command and can thus be overridden from your
@file{~/.emacs} file (@pxref{(emacs)Init File}).



@node Inserting Pairs
@chapter Inserting Matching Pairs of Characters
@cindex inserting pairs
@cindex pairs

  Various characters usually appear in pairs.  When, for example, you insert
an open parenthesis, no matter whether you are programming or writing prose,
you will surely enter a closing one later.  By entering both at the same time
and leaving the cursor inbetween, Emacs can guarantee you that such
parentheses are always balanced.  And if you have a non-qwerty keyboard, where
typing some of the stranger programming language symbols makes you bend your
fingers backwards, this can be quite relieving too.

@findex skeleton-pair-insert-maybe
@vindex skeleton-pair
  This is done by binding the first key (@pxref{(emacs)Rebinding}) of
the pair to @code{skeleton-pair-insert-maybe} instead of
@code{self-insert-command}.  The ``maybe'' comes from the fact that
this at-first surprising behavior is initially turned off.  To enable
it, you must set @code{skeleton-pair} to some non-@code{nil} value.
And even then, a positive argument (@pxref{(emacs)Arguments}) will
make this key behave like a self-inserting key
(@pxref{(emacs)Inserting Text}).

@vindex skeleton-pair-on-word
  While this breaks with the stated intention of always balancing pairs, it
turns out that one often doesn't want pairing to occur, when the following
character is part of a word.  If you want pairing to occur even then, set
@code{skeleton-pair-on-word} to some non-@code{nil} value.

@vindex skeleton-pair-alist
  Pairing is possible for all visible characters.  By default the
parenthesis @samp{(}, the square bracket @samp{[}, the brace
@samp{@{}, the pointed bracket @samp{<} and the backquote @samp{`} all
pair with the symmetrical character.  All other characters pair
themselves.  This behavior can be modified by the variable
@code{skeleton-pair-alist}.  This is in fact an alist of skeletons
(@pxref{Skeleton Language}), with the first part of each sublist
matching the typed character.  This is the position of the interactor,
but since pairs don't need the @code{str} element, this is ignored.

  Some modes have bound the command @code{skeleton-pair-insert-maybe}
to relevant keys.  These modes also configure the pairs as
appropriate.  For example, when typing english prose, you'd expect the
backquote (@samp{`}) to pair with the quote (@samp{'}), while in Shell
script mode it must pair to itself.  They can also inhibit pairing in
certain contexts.  For example an escaped character stands for itself.



@node Autoinserting
@chapter Autoinserting Text in Empty Files
@cindex autoinserting

@findex auto-insert
  @kbd{M-x auto-insert} will put some predefined text at the beginning of
the buffer.  The main application for this function, as its name suggests,
is to have it be called automatically every time an empty, and only an
empty file is visited.  This is accomplished by putting @code{(add-hook
'find-file-hook 'auto-insert)} into your @file{~/.emacs} file
(@pxref{(emacs)Init File}).

@vindex auto-insert-alist
  What gets inserted, if anything, is determined by the variable
@code{auto-insert-alist}.  The @sc{car}s of this list are each either
a mode name, making an element applicable when a buffer is in that
mode.  Or they can be a string, which is a regexp matched against the
buffer's file name.  In that way different kinds of files that have
the same mode in Emacs can be distinguished.  The @sc{car}s may also
be cons cells consisting of mode name or regexp as above and an
additional descriptive string.

  When a matching element is found, the @sc{cdr} says what to do.  It may
be a string, which is a file name, whose contents are to be inserted, if
that file is found in the directory @code{auto-insert-directory} or under a
absolute file name.  Or it can be a skeleton (@pxref{Skeleton Language}) to
be inserted.

  It can also be a function, which allows doing various things.  The function
can simply insert some text, indeed, it can be skeleton command (@pxref{Using
Skeletons}).  It can be a lambda function which will for example conditionally
call another function.  Or it can even reset the mode for the buffer. If you
want to perform several such actions in order, you use a vector, i.e. several
of the above elements between square brackets (@samp{[@r{@dots{}}]}).

  By default C and C++ headers insert a definition of a symbol derived from
the filename to prevent multiple inclusions.  C and C++ sources insert an
include of the header.  Makefiles insert the file makefile.inc if it exists.

  TeX and bibTeX mode files insert the file tex-insert.tex if it exists, while
LaTeX mode files insert a typical @code{\documentclass} frame.  Html
files insert a skeleton with the usual frame.

  Ada mode files call the Ada header skeleton command.  Emacs lisp
source files insert the usual header, with a copyright of your
environment variable @env{$ORGANIZATION} or else the FSF, and prompt
for valid keywords describing the contents.  Files in a @file{bin}
directory for which Emacs could determine no specialized mode
(@pxref{(emacs)Choosing Modes}) are set to Shell script mode.

@findex define-auto-insert
  In Lisp (@pxref{(emacs)Init File}) you can use the function
@code{define-auto-insert} to add to or modify
@code{auto-insert-alist}.  See its documentation with @kbd{C-h f
define-auto-insert}.

@vindex auto-insert
  The variable @code{auto-insert} says what to do when @code{auto-insert} is
called non-interactively, e.g. when a newly found file is empty (see above):
@table @asis
@item @code{nil}
Do nothing.
@item @code{t}
Insert something if possible, i.e. there is a matching entry in
@code{auto-insert-alist}.
@item other
Insert something if possible, but mark as unmodified.
@end table

@vindex auto-insert-query
  The variable @code{auto-insert-query} controls whether to ask about
inserting something.  When this is @code{nil}, inserting is only done with
@kbd{M-x auto-insert}.  When this is @code{function}, you are queried
whenever @code{auto-insert} is called as a function, such as when Emacs
visits an empty file and you have set the above-mentioned hook.  Otherwise
you are alway queried.

@vindex auto-insert-prompt
  When querying, the variable @code{auto-insert-prompt}'s value is used as a
prompt for a y-or-n-type question.  If this includes a @samp{%s} construct,
that is replaced by what caused the insertion rule to be chosen.  This is
either a descriptive text, the mode-name of the buffer or the regular
expression that matched the filename.



@node Copyrights
@chapter Inserting and Updating Copyrights
@cindex copyrights

@findex copyright
  @kbd{M-x copyright} is a skeleton inserting command, that adds a copyright
notice at the point.  The ``by'' part is taken from your environment variable
@env{$ORGANIZATION} or if that isn't set you are prompted for it.  If the
buffer has a comment syntax (@pxref{(emacs)Comments}), this is inserted as a comment.

@findex copyright-update
@vindex copyright-limit
@vindex copyright-current-year
  @kbd{M-x copyright-update} looks for a copyright notice in the first
@code{copyright-limit} characters of the buffer and updates it when necessary.
The current year (variable @code{copyright-current-year}) is added to the
existing ones, in the same format as the preceding year, i.e. 1994, '94 or 94.
If a dash-separated year list up to last year is found, that is extended to
current year, else the year is added separated by a comma.  Or it replaces
them when this is called with a prefix argument.  If a header referring to a
wrong version of the GNU General Public License (@pxref{(emacs)Copying}) is found,
that is updated too.

  An interesting application for this function is to have it be called
automatically every time a file is saved.  This is accomplished by
putting @code{(add-hook 'before-save-hook 'copyright-update)} into
your @file{~/.emacs} file (@pxref{(emacs)Init File}).  Alternative,
you can do @kbd{M-x customize-variable @key{RET} before-save-hook
@key{RET}}.  @code{copyright-update} is conveniently listed as an
option in the customization buffer.

@vindex copyright-query
  The variable @code{copyright-query} controls whether to update the
copyright or whether to ask about it.  When this is @code{nil} updating is
only done with @kbd{M-x copyright-update}.  When this is @code{function}
you are queried whenever @code{copyright-update} is called as a function,
such as in the @code{before-save-hook} feature mentioned above.  Otherwise
you are always queried.



@node Executables
@chapter Making Interpreter Scripts Executable
@cindex executables

@vindex executable-prefix
@vindex executable-chmod
  Various interpreter modes such as Shell script mode or AWK mode will
automatically insert or update the buffer's magic number, a special
comment on the first line that makes the @code{exec} systemcall know
how to execute the script.  To this end the script is automatically
made executable upon saving, with @code{executable-chmod} as argument
to the system @code{chmod} command.  The magic number is prefixed by
the value of @code{executable-prefix}.

@vindex executable-magicless-file-regexp
  Any file whose name matches @code{executable-magicless-file-regexp} is not
furnished with a magic number, nor is it made executable.  This is mainly
intended for resource files, which are only meant to be read in.

@vindex executable-insert
  The variable @code{executable-insert} says what to do when
@code{executable-set-magic} is called non-interactively, e.g. when file has no
or the wrong magic number:
@table @asis
@item @code{nil}
Do nothing.
@item @code{t}
Insert or update magic number.
@item other
Insert or update magic number, but mark as unmodified.
@end table

@findex executable-set-magic
@vindex executable-query
  The variable @code{executable-query} controls whether to ask about
inserting or updating the magic number.  When this is @code{nil} updating
is only done with @kbd{M-x executable-set-magic}.  When this is
@code{function} you are queried whenever @code{executable-set-magic} is
called as a function, such as when Emacs puts a buffer in Shell script
mode.  Otherwise you are alway queried.

@findex executable-self-display
  @kbd{M-x executable-self-display} adds a magic number to the buffer, which
will turn it into a self displaying text file, when called as a Un*x command.
The ``interpreter'' used is @code{executable-self-display} with argument
@samp{+2}.

@node Timestamps
@chapter Maintaining Timestamps in Modified Files
@cindex timestamps

@findex time-stamp
@vindex before-save-hook
The @code{time-stamp} command can be used to update automatically a
template in a file with a new time stamp every time you save the file.
Customize the hook @code{before-save-hook} to add the function
@code{time-stamp} to arrange this.  It you use Custom to do this,
then @code{time-stamp} is conveniently listed as an option in the
customization buffer.

@vindex time-stamp-active
@vindex time-stamp-format
@vindex time-stamp-start
The time stamp is updated only if the customizable variable
@code{time-stamp-active} is on, which it is by default; the command
@code{time-stamp-toggle-active} can be used to toggle it.  The format of
the time stamp is set by the customizable variable
@code{time-stamp-format}.

@vindex time-stamp-line-limit
@vindex time-stamp-end
@vindex time-stamp-count
@vindex time-stamp-inserts-lines
The variables @code{time-stamp-line-limit}, @code{time-stamp-start},
@code{time-stamp-end}, @code{time-stamp-count}, and
@code{time-stamp-inserts-lines} control finding the template.  Do not
change these in your init file or you will be incompatible with other
people's files.  If you must change them, do so only in the local
variables section of the file itself.

Normally the template must appear in the first 8 lines of a file and
look like one of the following:

@example
Time-stamp: <>
Time-stamp: " "
@end example

The time stamp is written between the brackets or quotes:

@example
Time-stamp: <1998-02-18 10:20:51 gildea>
@end example

@node QuickURL
@chapter QuickURL: Inserting URLs Based on Text at Point

@vindex quickurl-url-file
@findex quickurl
@cindex URLs
@kbd{M-x quickurl} can be used to insert a URL into a buffer based on
the text at point.  The URLs are stored in an external file defined by
the variable @code{quickurl-url-file} as a list of either cons cells of
the form @code{(@var{key} . @var{URL})} or
lists of the form @code{(@var{key} @var{URL} @var{comment})}.  These
specify that @kbd{M-x quickurl} should insert @var{URL} if the word
@var{key} is at point, for example:

@example
(("FSF"      "http://www.fsf.org/" "The Free Software Foundation")
 ("emacs"  . "http://www.emacs.org/")
 ("hagbard"  "http://www.hagbard.demon.co.uk" "Hagbard's World"))
@end example

@findex quickurl-add-url
@findex quickurl-list
@kbd{M-x quickurl-add-url} can be used to add a new @var{key}/@var{URL}
pair.  @kbd{M-x quickurl-list} provides interactive editing of the URL
list.

@node Tempo
@chapter Tempo: Flexible Template Insertion

@cindex templates
The Tempo package provides a simple way to define powerful templates, or
macros, if you wish.  It is mainly intended for, but not limited to,
programmers to be used for creating shortcuts for editing
certain kinds of documents.

@findex tempo-backward-mark
@findex tempo-forward-mark
A template is defined as a list of items to be inserted in the current
buffer at point.  Some can be simple strings, while others can control
formatting or define special points of interest in the inserted text.
@kbd{M-x tempo-backward-mark} and @kbd{M-x tempo-forward-mark} can be
used to jump between such points.

More flexible templates can be created by including Lisp symbols, which
will be evaluated as variables, or lists, which will be evaluated
as Lisp expressions.  Automatic completion of specified tags to expanded
templates can be provided.

@findex tempo-define-template
See the documentation for @code{tempo-define-template} for the different
items that can be used to define a tempo template with a command for
inserting it.

See the commentary in @file{tempo.el} for more information on using the
Tempo package.

@node Hippie Expand
@chapter `Hippie' Expansion

@findex hippie-expand
@kindex M-/
@vindex hippie-expand-try-functions-list
@kbd{M-x hippie-expand} is a single command providing a variety of
completions and expansions.  Called repeatedly, it tries all possible
completions in succession.

Which ones to try, and in which order, is determined by the contents of
the customizable option @code{hippie-expand-try-functions-list}.  Much
customization of the expansion behavior can be made by changing the
order of, removing, or inserting new functions in this list.  Given a
positive numeric argument, @kbd{M-x hippie-expand} jumps directly that
number of functions forward in this list.  Given some other argument (a
negative argument or just @kbd{C-u}) it undoes the tried completion.

See the commentary in @file{hippie-exp.el} for more information on the
possibilities.

Typically you would bind @code{hippie-expand} to @kbd{M-/} with
@code{dabbrev-expand}, the standard binding of @kbd{M-/}, providing one
of the expansion possibilities.
