68 | @chapter Introduction | |
69 | ||
70 | When working in software projects using C++, I frequently missed | |
71 | software support for two things: | |
72 | ||
73 | @itemize @bullet | |
74 | @item | |
75 | When you get a new class library, or you have to work on source code you | |
76 | haven't written yourself (or written sufficiently long ago), you need a | |
77 | tool to let you navigate class hierarchies and investigate | |
78 | features of the software. Without such a tool you often end up | |
79 | @command{grep}ing through dozens or even hundreds of files. | |
80 | ||
81 | @item | |
82 | Once you are productive, it would be nice to have a tool that knows your | |
83 | sources and can help you while you are editing source code. Imagine to | |
84 | be able to jump to the definition of an identifier while you are | |
85 | editing, or something that can complete long identifier names because it | |
86 | knows what identifiers are defined in your program@dots{}. | |
87 | @end itemize | |
88 | ||
89 | The design of Ebrowse reflects these two needs. | |
90 | ||
91 | How does it work? | |
92 | ||
93 | @cindex parser for C++ sources | |
94 | A fast parser written in C is used to process C++ source files. | |
95 | The parser generates a data base containing information about classes, | |
96 | members, global functions, defines, types etc.@: found in the sources. | |
97 | ||
98 | The second part of Ebrowse is a Lisp program. This program reads | |
99 | the data base generated by the parser. It displays its contents in | |
100 | various forms and allows you to perform operations on it, or do | |
101 | something with the help of the knowledge contained in the data base. | |
102 | ||
103 | @cindex major modes, of Ebrowse buffers | |
104 | @dfn{Navigational} use of Ebrowse is centered around two | |
105 | types of buffers which define their own major modes: | |
106 | ||
107 | @cindex tree buffer | |
108 | @dfn{Tree buffers} are used to view class hierarchies in tree form. | |
109 | They allow you to quickly find classes, find or view class declarations, | |
110 | perform operations like query replace on sets of your source files, and | |
111 | finally tree buffers are used to produce the second buffer form---member | |
112 | buffers. @xref{Tree Buffers}. | |
113 | ||
114 | @cindex member buffer | |
115 | Members are displayed in @dfn{member buffers}. Ebrowse | |
116 | distinguishes between six different types of members; each type is | |
117 | displayed as a member list of its own: | |
118 | ||
119 | @itemize @bullet | |
120 | @item | |
121 | Instance member variables; | |
122 | ||
123 | @item | |
124 | Instance member functions; | |
125 | ||
126 | @item | |
127 | Static member variables; | |
128 | ||
129 | @item | |
130 | Static member functions; | |
131 | ||
132 | @item | |
133 | Friends/Defines. The list of defines is contained in the friends | |
134 | list of the pseudo-class @samp{*Globals*}; | |
135 | ||
136 | @item | |
137 | Types (@code{enum}s, and @code{typedef}s defined with class | |
138 | scope).@refill | |
139 | @end itemize | |
140 | ||
141 | You can switch member buffers from one list to another, or to another | |
142 | class. You can include inherited members in the display, you can set | |
143 | filters that remove categories of members from the display, and most | |
144 | importantly you can find or view member declarations and definitions | |
145 | with a keystroke. @xref{Member Buffers}. | |
146 | ||
147 | These two buffer types and the commands they provide support the | |
148 | navigational use of the browser. The second form resembles Emacs' Tags | |
149 | package for C and other procedural languages. Ebrowse's commands of | |
150 | this type are not confined to special buffers; they are most often used | |
151 | while you are editing your source code. | |
152 | ||
153 | To list just a subset of what you can use the Tags part of Ebrowse for: | |
154 | ||
155 | @itemize @bullet | |
156 | @item | |
157 | Jump to the definition or declaration of an identifier in your source | |
158 | code, with an electric position stack that lets you easily navigate | |
159 | back and forth. | |
160 | ||
161 | @item | |
162 | Complete identifiers in your source with a completion list containing | |
163 | identifiers from your source code only. | |
164 | ||
165 | @item | |
166 | Perform search and query replace operations over some or all of your | |
167 | source files. | |
168 | ||
169 | @item | |
170 | Show all identifiers matching a regular expression---and jump to one of | |
171 | them, if you like. | |

180 | ||
181 | @cindex @command{ebrowse}, the program | |
182 | @cindex class data base creation | |
183 | Before you can start browsing a class hierarchy, you must run the parser | |
184 | @command{ebrowse} on your source files in order to generate a Lisp data | |
185 | base describing your program. | |
186 | ||
187 | @cindex command line for @command{ebrowse} | |
188 | The operation of @command{ebrowse} can be tailored with command line | |
189 | options. Under normal circumstances it suffices to let the parser use | |
190 | its default settings. If you want to do that, call it with a command | |
191 | line like: | |
192 | ||
193 | @example | |
194 | ebrowse *.h *.cc | |
195 | @end example | |
196 | ||
197 | @noindent | |
198 | or, if your shell doesn't allow all the file names to be specified on | |
199 | the command line, | |
200 | ||
201 | @example | |
202 | ebrowse --files=@var{file} | |
203 | @end example | |
204 | ||
205 | @noindent | |
206 | where @var{file} contains the names of the files to be parsed, one | |
207 | per line. | |
208 | ||
209 | @findex --help | |
210 | When invoked with option @samp{--help}, @command{ebrowse} prints a list of | |
211 | available command line options.@refill | |

227 | ||
228 | @table @samp | |
229 | @cindex input files, for @command{ebrowse} | |
230 | @item file | |
231 | Each file name on the command line tells @command{ebrowse} to parse | |
232 | that file. | |
233 | ||
234 | @cindex response files | |
235 | @findex --files | |
236 | @item --files=@var{file} | |
237 | This command line switch specifies that @var{file} contains a list of | |
238 | file names to parse. Each line in @var{file} must contain one file | |
239 | name. More than one option of this kind is allowed. You might, for | |
240 | instance, want to use one file for header files, and another for source | |
241 | files. | |
242 | ||
243 | @cindex standard input, specifying input files | |
244 | @item standard input | |
245 | When @command{ebrowse} finds no file names on the command line, and no | |
246 | @samp{--file} option is specified, it reads file names from standard | |
247 | input. This is sometimes convenient when @command{ebrowse} is used as part | |
248 | of a command pipe. | |
249 | ||
250 | @findex --search-path | |
251 | @item --search-path=@var{paths} | |
252 | This option lets you specify search paths for your input files. | |
253 | @var{paths} is a list of directory names, separated from each other by a | |
254 | either a colon or a semicolon, depending on the operating system. | |
255 | @end table | |
256 | ||
257 | @cindex header files | |
258 | @cindex friend functions | |
259 | It is generally a good idea to specify input files so that header files | |
260 | are parsed before source files. This facilitates the parser's work of | |
261 | properly identifying friend functions of a class. | |

271 | @findex --output-file | |
272 | @cindex @file{BROWSE} file | |
273 | @item --output-file=@var{file} | |
274 | This option instructs @command{ebrowse} to generate a Lisp data base with | |
275 | name @var{file}. By default, the data base is named @file{BROWSE}, and | |
276 | is written in the directory in which @command{ebrowse} is invoked. | |
277 | ||
278 | If you regularly use data base names different from the default, you | |
279 | might want to add this to your init file: | |
280 | ||
281 | @lisp | |
282 | (add-to-list 'auto-mode-alist '(@var{NAME} . ebrowse-tree-mode)) | |
283 | @end lisp | |
284 | ||
285 | @noindent | |
286 | where @var{NAME} is the Lisp data base name you are using. | |
287 | ||
288 | @findex --append | |
289 | @cindex appending output to class data base | |
290 | @item --append | |
291 | By default, each run of @command{ebrowse} erases the old contents of the | |
292 | output file when writing to it. You can instruct @command{ebrowse} to | |
293 | append its output to an existing file produced by @command{ebrowse} | |
294 | with this command line option. | |

308 | @item --no-structs-or-unions | |
309 | This switch suppresses all classes in the data base declared as | |
310 | @code{struct} or @code{union} in the output. | |
311 | ||
312 | This is mainly useful when you are converting an existing | |
313 | C program to C++, and do not want to see the old C structs in a class | |
314 | tree. | |

322 | @section Regular Expressions | |
323 | ||
324 | @cindex regular expressions, recording | |
325 | The parser @command{ebrowse} normally writes regular expressions to its | |
326 | output file that help the Lisp part of Ebrowse to find functions, | |
327 | variables etc.@: in their source files. | |
328 | ||
329 | You can instruct @command{ebrowse} to omit these regular expressions by | |
330 | calling it with the command line switch @samp{--no-regexps}. | |
331 | ||
332 | When you do this, the Lisp part of Ebrowse tries to guess, from member | |
333 | or class names, suitable regular expressions to locate that class or | |
334 | member in source files. This works fine in most cases, but the | |
335 | automatic generation of regular expressions can be too weak if unusual | |
336 | coding styles are used. | |
337 | ||
338 | @table @samp | |
339 | @findex --no-regexps | |
340 | @item --no-regexps | |
341 | This option turns off regular expression recording. | |
342 | ||
343 | @findex --min-regexp-length | |
344 | @cindex minimum regexp length for recording | |
345 | @item --min-regexp-length=@var{n} | |
346 | The number @var{n} following this option specifies the minimum length of | |
347 | the regular expressions recorded to match class and member declarations | |
348 | and definitions. The default value is set at compilation time of | |
349 | @command{ebrowse}. | |
350 | ||
351 | The smaller the minimum length, the higher the probability that | |
352 | Ebrowse will find a wrong match. The larger the value, the | |
353 | larger the output file and therefore the memory consumption once the | |
354 | file is read from Emacs. | |
355 | ||
356 | @findex --max-regexp-length | |
357 | @cindex maximum regexp length for recording | |
358 | @item --max-regexp-length=@var{n} | |
359 | The number following this option specifies the maximum length of the | |
360 | regular expressions used to match class and member declarations and | |
361 | definitions. The default value is set at compilation time of | |
362 | @command{ebrowse}. | |
363 | ||
364 | The larger the maximum length, the higher the probability that the | |
365 | browser will find a correct match, but the larger the value the larger | |
366 | the output file and therefore the memory consumption once the data is | |
367 | read. As a second effect, the larger the regular expression, the higher | |
368 | the probability that it will no longer match after editing the file. | |

415 | @cindex mouse highlight in tree buffers | |
416 | When you run Emacs on a display which supports colors and the mouse, you | |
417 | will notice that certain areas in the tree buffer are highlighted | |
418 | when you move the mouse over them. This highlight marks mouse-sensitive | |
419 | regions in the buffer. Please notice the help strings in the echo area | |
420 | when the mouse moves over a sensitive region. | |
421 | ||
422 | @cindex context menu | |
423 | A click with @kbd{Mouse-3} on a mouse-sensitive region opens a context | |
424 | menu. In addition to this, each buffer also has a buffer-specific menu | |
425 | that is opened with a click with @kbd{Mouse-3} somewhere in the buffer | |
426 | where no highlight is displayed. | |

442 | Class trees are displayed in @dfn{tree buffers} which install their own | |
443 | major mode. Most Emacs keys work in tree buffers in the usual way, | |
444 | e.g.@: you can move around in the buffer with the usual @kbd{C-f}, | |
445 | @kbd{C-v} etc., or you can search with @kbd{C-s}. | |
446 | ||
447 | Tree-specific commands are bound to simple keystrokes, similar to | |
448 | @code{Gnus}. You can take a look at the key bindings by entering | |
449 | @kbd{?} which calls @code{M-x describe-mode} in both tree and member | |

511 | starting with @kbd{L} when the cursor is on a class name. By default, | |
512 | there is only one member buffer named @dfn{*Members*} that is reused | |
513 | each time you display a member list---this has proven to be more | |
514 | practical than to clutter up the buffer list with dozens of member | |
515 | buffers. | |
516 | ||
517 | If you want to display more than one member list at a time you can | |
518 | @dfn{freeze} its member buffer. Freezing a member buffer prevents it | |
519 | from being overwritten the next time you display a member list. You can | |
520 | toggle this buffer status at any time. | |
521 | ||
522 | Every member list display command in the tree buffer can be used with a | |
523 | prefix argument (@kbd{C-u}). Without a prefix argument, the command will | |
524 | pop to a member buffer displaying the member list. With prefix argument, | |
525 | the member buffer will additionally be @dfn{frozen}. | |
526 | ||

793 | @dfn{Member buffers} are used to operate on lists of members of a class. | |
794 | Ebrowse distinguishes six kinds of lists: | |
795 | ||
796 | @itemize @bullet | |
797 | @item | |
798 | Instance variables (normal member variables); | |

808 | Types (@code{enum}s and @code{typedef}s defined with class scope. | |
809 | Nested classes will be shown in the class tree like normal classes. | |
810 | @end itemize | |
811 | ||
812 | Like tree buffers, member buffers install their own major mode. Also | |
813 | like in tree buffers, menus are provided for certain areas in the | |
814 | buffer: members, classes, and the buffer itself. | |
815 | ||

1275 | If more than one class contains a member with the given name you can | |
1276 | select the class with completion. If there is a scope declaration in | |

1318 | @section The Position Stack | |
1319 | @cindex position stack | |
1320 | ||
1321 | When jumping to a member declaration or definition with one of | |
1322 | Ebrowse's commands, the position from where you performed the | |
1323 | jump and the position where you jumped to are recorded in a | |
1324 | @dfn{position stack}. There are several ways in which you can quickly | |
1325 | move to positions in the stack:@refill | |
1326 | ||
1327 | @table @kbd | |
1328 | @cindex return to original position | |
1329 | @item C-c C-m - | |
1330 | This command sets point to the previous position in the position stack. | |
1331 | Directly after you performed a jump, this will put you back to the | |
1332 | position where you came from. | |
1333 | ||
1334 | The stack is not popped, i.e.@: you can always switch back and forth | |
1335 | between positions in the stack. To avoid letting the stack grow to | |
1336 | infinite size there is a maximum number of positions defined. When this | |
1337 | number is reached, older positions are discarded when new positions are | |
1338 | pushed on the stack. | |
1339 | ||
1340 | @item C-c C-m + | |
1341 | This command moves forward in the position stack, setting point to | |
1342 | the next position stored in the position stack. | |
1343 | ||
1344 | @item C-c C-m p | |
1345 | Displays an electric buffer showing all positions saved in the stack. | |
1346 | You can select a position by pressing @kbd{SPC} in a line. You can | |
1347 | view a position with @kbd{v}. | |

1360 | Ebrowse allows you to perform operations on all or a subset of the files | |
1361 | mentioned in a class tree. When you invoke one of the following | |
1362 | functions and more than one class tree is loaded, you must choose a | |
1363 | class tree to use from an electric tree menu. If the selected tree | |
1364 | contains marked classes, the following commands operate on the files | |

1414 | ||
1415 | A special buffer is popped up containing all identifiers matching the | |
1416 | regular expression, and what kind of symbol it is (e.g.@: a member | |
1417 | function, or a type). You can then switch to this buffer, and use the | |
