Without such a tool you often end up @command{grep}ing through dozens or even hundreds of files. @item Once you are productive, it would be nice to have a tool that knows your sources and can help you while you are editing source code. Imagine to be able to jump to the definition of an identifier while you are editing, or something that can complete long identifier names because it knows what identifiers are defined in your program@dots{}. @end itemize The design of Ebrowse reflects these two needs. How does it work? @cindex parser for C++ sources A fast parser written in C is used to process C++ source files. The parser generates a data base containing information about classes, members, global functions, defines, types etc.@: found in the sources. The second part of Ebrowse is a Lisp program. This program reads the data base generated by the parser. It displays its contents in various forms and allows you to perform operations on it, or do something with the help of the knowledge contained in the data base. @cindex major modes, of Ebrowse buffers @dfn{Navigational} use of Ebrowse is centered around two types of buffers which define their own major modes: @cindex tree buffer @dfn{Tree buffers} are used to view class hierarchies in tree form. They allow you to quickly find classes, find or view class declarations, perform operations like query replace on sets of your source files, and finally tree buffers are used to produce the second buffer form---member buffers. @xref{Tree Buffers}. @cindex member buffer Members are displayed in @dfn{member buffers}. Ebrowse distinguishes between six different types of members; each type is displayed as a member list of its own: @itemize @bullet @item Instance member variables; @item Instance member functions; @item Static member variables; @item Static member functions; @item Friends/Defines. The list of defines is contained in the friends list of the pseudo-class @samp{*Globals*}; @item Types (@code{enum}s, and @code{typedef}s defined with class scope).@refill @end itemize You can switch member buffers from one list to another, or to another class. You can include inherited members in the display, you can set filters that remove categories of members from the display, and most importantly you can find or view member declarations and definitions with a keystroke. @xref{Member Buffers}. These two buffer types and the commands they provide support the navigational use of the browser. The second form resembles Emacs' Tags package for C and other procedural languages. Ebrowse's commands of this type are not confined to special buffers; they are most often used while you are editing your source code. To list just a subset of what you can use the Tags part of Ebrowse for: @itemize @bullet @item Jump to the definition or declaration of an identifier in your source code, with an electric position stack that lets you easily navigate back and forth. @item Complete identifiers in your source with a completion list containing identifiers from your source code only. @item Perform search and query replace operations over some or all of your source files. @item Show all identifiers matching a regular expression---and jump to one of them, if you like. @end itemize @node Generating browser files, Loading a Tree, Overview, Top @comment node-name, next, previous, up @chapter Processing Source Files @cindex @command{ebrowse}, the program @cindex class data base creation Before you can start browsing a class hierarchy, you must run the parser @command{ebrowse} on your source files in order to generate a Lisp data base describing your program. @cindex command line for @command{ebrowse} The operation of @command{ebrowse} can be tailored with command line options. Under normal circumstances it suffices to let the parser use its default settings. If you want to do that, call it with a command line like: @example ebrowse *.h *.cc @end example @noindent or, if your shell doesn't allow all the file names to be specified on the command line, @example ebrowse --files=@var{file} @end example @noindent where @var{file} contains the names of the files to be parsed, one per line. @findex --help When invoked with option @samp{--help}, @command{ebrowse} prints a list of available command line options.@refill @menu * Input files:: Specifying which files to parse * Output file:: Changing the output file name * Structs and unions:: Omitting @code{struct}s and @code{union}s * Matching:: Setting regular expression lengths * Verbosity:: Getting feedback for lengthy operations @end menu @comment name, next, prev, up @node Input files, Output file, Generating browser files, Generating browser files @section Specifying Input Files @table @samp @cindex input files, for @command{ebrowse} @item file Each file name on the command line tells @command{ebrowse} to parse that file. @cindex response files @findex --files @item --files=@var{file} This command line switch specifies that @var{file} contains a list of file names to parse. Each line in @var{file} must contain one file name. More than one option of this kind is allowed. You might, for instance, want to use one file for header files, and another for source files. @cindex standard input, specifying input files @item standard input When @command{ebrowse} finds no file names on the command line, and no @samp{--file} option is specified, it reads file names from standard input. This is sometimes convenient when @command{ebrowse} is used as part of a command pipe. @findex --search-path @item --search-path=@var{paths} This option lets you specify search paths for your input files. @var{paths} is a list of directory names, separated from each other by a either a colon or a semicolon, depending on the operating system. @end table @cindex header files @cindex friend functions It is generally a good idea to specify input files so that header files are parsed before source files. This facilitates the parser's work of properly identifying friend functions of a class. @comment name, next, prev, up @node Output file, Structs and unions, Input files, Generating browser files @section Changing the Output File Name @table @samp @cindex output file name @findex --output-file @cindex @file{BROWSE} file @item --output-file=@var{file} This option instructs @command{ebrowse} to generate a Lisp data base with name @var{file}. By default, the data base is named @file{BROWSE}, and is written in the directory in which @command{ebrowse} is invoked. If you regularly use data base names different from the default, you might want to add this to your init file: @lisp (add-to-list 'auto-mode-alist '(@var{NAME} . ebrowse-tree-mode)) @end lisp @noindent where @var{NAME} is the Lisp data base name you are using. @findex --append @cindex appending output to class data base @item --append By default, each run of @command{ebrowse} erases the old contents of the output file when writing to it. You can instruct @command{ebrowse} to append its output to an existing file produced by @command{ebrowse} with this command line option. @end table @comment name, next, prev, up @node Structs and unions, Matching, Output file, Generating browser files @section Structs and Unions @cindex structs @cindex unions @table @samp @findex --no-structs-or-unions @item --no-structs-or-unions This switch suppresses all classes in the data base declared as @code{struct} or @code{union} in the output. This is mainly useful when you are converting an existing C program to C++, and do not want to see the old C structs in a class tree. @end table @comment name, next, prev, up @node Matching, Verbosity, Structs and unions, Generating browser files @section Regular Expressions @cindex regular expressions, recording The parser @command{ebrowse} normally writes regular expressions to its output file that help the Lisp part of Ebrowse to find functions, variables etc.@: in their source files. You can instruct @command{ebrowse} to omit these regular expressions by calling it with the command line switch @samp{--no-regexps}. When you do this, the Lisp part of Ebrowse tries to guess, from member or class names, suitable regular expressions to locate that class or member in source files. This works fine in most cases, but the automatic generation of regular expressions can be too weak if unusual coding styles are used. @table @samp @findex --no-regexps @item --no-regexps This option turns off regular expression recording. @findex --min-regexp-length @cindex minimum regexp length for recording @item --min-regexp-length=@var{n} The number @var{n} following this option specifies the minimum length of the regular expressions recorded to match class and member declarations and definitions. The default value is set at compilation time of @command{ebrowse}. The smaller the minimum length, the higher the probability that Ebrowse will find a wrong match. The larger the value, the larger the output file and therefore the memory consumption once the file is read from Emacs. @findex --max-regexp-length @cindex maximum regexp length for recording @item --max-regexp-length=@var{n} The number following this option specifies the maximum length of the regular expressions used to match class and member declarations and definitions. The default value is set at compilation time of @command{ebrowse}. The larger the maximum length, the higher the probability that the browser will find a correct match, but the larger the value the larger the output file and therefore the memory consumption once the data is read. As a second effect, the larger the regular expression, the higher the probability that it will no longer match after editing the file. @end table @node Verbosity, , Matching, Generating browser files @comment node-name, next, previous, up @section Verbose Mode @cindex verbose operation @table @samp @findex --verbose @item --verbose When this option is specified on the command line, @command{ebrowse} prints a period for each file parsed, and it displays a @samp{+} for each class written to the output file. @findex --very-verbose @item --very-verbose This option makes @command{ebrowse} print out the names of the files and the names of the classes seen. @end table @node Loading a Tree, Tree Buffers, Generating browser files, Top @comment node-name, next, previous, up @chapter Starting to Browse @cindex loading @cindex browsing You start browsing a class hierarchy parsed by @command{ebrowse} by just finding the @file{BROWSE} file with @kbd{C-x C-f}. An example of a tree buffer display is shown below. @example | Collection | IndexedCollection | Array | FixedArray | Set | Dictionary @end example @cindex mouse highlight in tree buffers When you run Emacs on a display which supports colors and the mouse, you will notice that certain areas in the tree buffer are highlighted when you move the mouse over them. This highlight marks mouse-sensitive regions in the buffer. Please notice the help strings in the echo area when the mouse moves over a sensitive region. @cindex context menu A click with @kbd{Mouse-3} on a mouse-sensitive region opens a context menu. In addition to this, each buffer also has a buffer-specific menu that is opened with a click with @kbd{Mouse-3} somewhere in the buffer where no highlight is displayed. @comment **************************************************************** @comment *** @comment *** TREE BUFFERS @comment *** @comment **************************************************************** @node Tree Buffers, Member Buffers, Loading a Tree, Top @comment node-name, next, previous, up @chapter Tree Buffers @cindex tree buffer mode @cindex class trees Class trees are displayed in @dfn{tree buffers} which install their own major mode. Most Emacs keys work in tree buffers in the usual way, e.g.@: you can move around in the buffer with the usual @kbd{C-f}, @kbd{C-v} etc., or you can search with @kbd{C-s}. Tree-specific commands are bound to simple keystrokes, similar to @code{Gnus}. You can take a look at the key bindings by entering @kbd{?} which calls @code{M-x describe-mode} in both tree and member buffers. @menu * Source Display:: Viewing and finding a class declaration * Member Display:: Showing members, switching to member buffers * Go to Class:: Finding a class * Quitting:: Discarding and burying the tree buffer * File Name Display:: Showing file names in the tree * Expanding and Collapsing:: Expanding and collapsing branches * Tree Indentation:: Changing the tree indentation * Killing Classes:: Removing class from the tree * Saving a Tree:: Saving a modified tree * Statistics:: Displaying class tree statistics * Marking Classes:: Marking and unmarking classes @end menu @node Source Display, Member Display, Tree Buffers, Tree Buffers @comment node-name, next, previous, up @section Viewing and Finding Class Declarations @cindex viewing, class @cindex finding a class @cindex class declaration You can view or find a class declaration when the cursor is on a class name. @table @kbd @item SPC This command views the class declaration if the database contains informations about it. If you don't parse the entire source you are working on, some classes will only be known to exist but the location of their declarations and definitions will not be known.@refill @item RET Works like @kbd{SPC}, except that it finds the class declaration rather than viewing it, so that it is ready for editing.@refill @end table The same functionality is available from the menu opened with @kbd{Mouse-3} on the class name. @node Member Display, Go to Class, Source Display, Tree Buffers @comment node-name, next, previous, up @section Displaying Members @cindex @samp{*Members*} buffer @cindex @samp{*Globals*} @cindex freezing a member buffer @cindex member lists, in tree buffers Ebrowse distinguishes six different kinds of members, each of which is displayed as a separate @dfn{member list}: instance variables, instance functions, static variables, static functions, friend functions, and types. Each of these lists can be displayed in a member buffer with a command starting with @kbd{L} when the cursor is on a class name. By default, there is only one member buffer named @dfn{*Members*} that is reused each time you display a member list---this has proven to be more practical than to clutter up the buffer list with dozens of member buffers. If you want to display more than one member list at a time you can @dfn{freeze} its member buffer. Freezing a member buffer prevents it from being overwritten the next time you display a member list. You can toggle this buffer status at any time. Every member list display command in the tree buffer can be used with a prefix argument (@kbd{C-u}). Without a prefix argument, the command will pop to a member buffer displaying the member list. With prefix argument, the member buffer will additionally be @dfn{frozen}. @table @kbd @cindex instance member variables, list @item L v This command displays the list of instance member variables. @cindex static variables, list @item L V Display the list of static variables. @cindex friend functions, list @item L d Display the list of friend functions. This list is used for defines if you are viewing the class @samp{*Globals*} which is a place holder for global symbols. @cindex member functions, list @item L f Display the list of member functions. @cindex static member functions, list @item L F Display the list of static member functions. @cindex types, list @item L t Display a list of types. @end table These lists are also available from the class' context menu invoked with @kbd{Mouse-3} on the class name. @node Go to Class, Quitting, Member Display, Tree Buffers @comment node-name, next, previous, up @section Finding a Class @cindex locate class @cindex expanding branches @cindex class location @table @kbd @cindex search for class @item / This command reads a class name from the minibuffer with completion and positions the cursor on the class in the class tree. If the branch of the class tree containing the class searched for is currently collapsed, the class itself and all its base classes are recursively made visible. (See also @ref{Expanding and Collapsing}.)@refill This function is also available from the tree buffer's context menu. @item n Repeat the last search done with @kbd{/}. Each tree buffer has its own local copy of the regular expression last searched in it. @end table @node Quitting, File Name Display, Go to Class, Tree Buffers @comment node-name, next, previous, up @section Burying a Tree Buffer @cindex burying tree buffer @table @kbd @item q Is a synonym for @kbd{M-x bury-buffer}. @end table @node File Name Display, Expanding and Collapsing, Quitting, Tree Buffers @comment node-name, next, previous, up @section Displaying File Names @table @kbd @cindex file names in tree buffers @item T f This command toggles the display of file names in a tree buffer. If file name display is switched on, the names of the files containing the class declaration are shown to the right of the class names. If the file is not known, the string @samp{unknown} is displayed. This command is also provided in the tree buffer's context menu. @item s Display file names for the current line, or for the number of lines given by a prefix argument. @end table Here is an example of a tree buffer with file names displayed. @example | Collection (unknown) | IndexedCollection (indexedcltn.h) | Array (array.h) | FixedArray (fixedarray.h) | Set (set.h) | Dictionary (dict.h) @end example @node Expanding and Collapsing, Tree Indentation, File Name Display, Tree Buffers @comment node-name, next, previous, up @section Expanding and Collapsing a Tree @cindex expand tree branch @cindex collapse tree branch @cindex branches of class tree @cindex class tree, collapse or expand You can expand and collapse parts of a tree to reduce the complexity of large class hierarchies. Expanding or collapsing branches of a tree has no impact on the functionality of other commands, like @kbd{/}. (See also @ref{Go to Class}.)@refill Collapsed branches are indicated with an ellipsis following the class name like in the example below. @example | Collection | IndexedCollection... | Set | Dictionary @end example @table @kbd @item - This command collapses the branch of the tree starting at the class the cursor is on. @item + This command expands the branch of the tree starting at the class the cursor is on. Both commands for collapsing and expanding branches are also available from the class' object menu. @item * This command expands all collapsed branches in the tree. @end table @node Tree Indentation, Killing Classes, Expanding and Collapsing, Tree Buffers @comment node-name, next, previous, up @section Changing the Tree Indentation @cindex tree indentation @cindex indentation of the tree @table @kbd @item T w This command reads a new indentation width from the minibuffer and redisplays the tree buffer with the new indentation It is also available from the tree buffer's context menu. @end table @node Killing Classes, Saving a Tree, Tree Indentation, Tree Buffers @comment node-name, next, previous, up @section Removing Classes from the Tree @cindex killing classes @cindex class, remove from tree @table @kbd @item C-k This command removes the class the cursor is on and all its derived classes from the tree.

This is useful after classes have been deleted from a tree. @item C-x C-w Writes the tree to a file whose name is read from the minibuffer. @end table @node Statistics, Marking Classes, Saving a Tree, Tree Buffers @comment node-name, next, previous, up @cindex statistics for a tree @cindex tree statistics @cindex class statistics @table @kbd @item x Display statistics for the tree, like number of classes in it, number of member functions, etc. This command can also be found in the buffer's context menu. @end table @node Marking Classes, , Statistics, Tree Buffers @comment node-name, next, previous, up @cindex marking classes @cindex operations on marked classes Classes can be marked for operations similar to the standard Emacs commands @kbd{M-x tags-search} and @kbd{M-x tags-query-replace} (see also @xref{Tags-like Functions}.)@refill @table @kbd @cindex toggle mark @item M t Toggle the mark of the line point is in or for as many lines as given by a prefix command. This command can also be found in the class' context menu. @cindex unmark all @item M a Unmark all classes. With prefix argument @kbd{C-u}, mark all classes in the tree. Since this command operates on the whole buffer, it can also be found in the buffer's object menu. @end table Marked classes are displayed with an @code{>} in column one of the tree display, like in the following example @example |> Collection | IndexedCollection... |> Set | Dictionary @end example @c **************************************************************** @c *** @c *** MEMBER BUFFERS @c *** @c **************************************************************** @node Member Buffers, Tags-like Functions, Tree Buffers, Top @comment node-name, next, previous, up @chapter Member Buffers @cindex members @cindex member buffer mode @cindex class members, types @cindex types of class members @dfn{Member buffers} are used to operate on lists of members of a class.

If you invoke this function with a prefix argument, the declaration is searched. If more than one class contains a member with the given name you can select the class with completion. If there is a scope declaration in front of the member name, this class name is used as initial input for the completion. @item C-c b F Find the declaration of the member around point. @item C-c b v View the definition of the member around point. @item C-c b V View the declaration of the member around point. @item C-c b 4 f Find a member's definition in another window. @item C-c b 4 F Find a member's declaration in another window. @item C-c b 4 v View a member's definition in another window. @item C-c b 4 V View a member's declaration in another window. @item C-c b 5 f Find a member's definition in another frame. @item C-c b 5 F Find a member's declaration in another frame. @item C-c b 5 v View a member's definition in another frame. @item C-c b 5 V View a member's declaration in another frame. @end table @node Position Stack, Search & Replace, Finding and Viewing, Tags-like Functions @comment node-name, next, previous, up @section The Position Stack @cindex position stack When jumping to a member declaration or definition with one of Ebrowse's commands, the position from where you performed the jump and the position where you jumped to are recorded in a @dfn{position stack}. There are several ways in which you can quickly move to positions in the stack:@refill @table @kbd @cindex return to original position @item C-c b - This command sets point to the previous position in the position stack. Directly after you performed a jump, this will put you back to the position where you came from. The stack is not popped, i.e.@: you can always switch back and forth between positions in the stack. To avoid letting the stack grow to infinite size there is a maximum number of positions defined. When this number is reached, older positions are discarded when new positions are pushed on the stack. @item C-c b + This command moves forward in the position stack, setting point to the next position stored in the position stack. @item C-c b p Displays an electric buffer showing all positions saved in the stack. You can select a position by pressing @kbd{SPC} in a line.

When you invoke one of the following functions and more than one class tree is loaded, you must choose a class tree to use from an electric tree menu. If the selected tree contains marked classes, the following commands operate on the files mentioned in the marked classes only. Otherwise all files in the class tree are used. @table @kbd @item C-c b s This function performs a regular expression search in the chosen set of files. @item C-c b u This command performs a search for calls of a given member which is selected in the usual way with completion. @item C-c b % Perform a query replace over the set of files. @item C-c b , All three operations above stop when finding a match.

This command can be very useful if you remember only part of a member name, and not its beginning. A special buffer is popped up containing all identifiers matching the regular expression, and what kind of symbol it is (e.g.@: a member function, or a type). You can then switch to this buffer, and use the command @kbd{C-c b f}, for example, to jump to a specific member. @node Symbol Completion, Member Buffer Display, Apropos, Tags-like Functions @comment node-name, next, previous, up @section Symbol Completion @cindex completion @cindex symbol completion The command @kbd{C-c b TAB} completes the symbol in front of point. @node Member Buffer Display, , Symbol Completion, Tags-like Functions @section Quick Member Display @cindex member buffer, for member at point You can quickly display a member buffer containing the member the cursor in on with the command @kbd{C-c b m}. @node Concept Index, , Tags-like Functions, Top @unnumbered Concept Index @printindex cp @contents @bye @ignore arch-tag: 52fe78ac-a1c4-48e7-815e-0a31acfad4bf @end ignore
