2
3 * etags.c: (longopts): New undocumented option --no-duplicates.
4 (no_duplicates): Static variables for the above option.
5 (print_help): Do not print help for --no-warn, now undocumented.
6 (add_node): Allow duplicate tags in ctags mode unless --no-duplicates.
7 (main): Pass the -u option to sort in ctags mode.
8
9 2006-12-28 Francesco Potortì <pot@gnu.org>
10
11 * etags.c (readline): When creating a relative file name from a
12 #line directive, leave the file name alone. The previous
13 behaviour was to make it relative to the tags file directory,
14 under the hypothesis that the #line directive file name was
15 relative to the directory of the tagged file. That hypothesis is
16 wrong with Cpp and Lex.
17
18 2006-12-20 Francesco Potortì <pot@gnu.org>
19
20 * etags.c (C_entries): DEFUN names were longer by one: corrected.

26
27 2006-08-12 Jan Djärv <jan.h.d@swipnet.se>

30
31 2006-08-12 Francesco Potortì <pot@gnu.org>
32
33 * etags.c (readline): lno is unsigned.
34 (TeX_commands): Use p++ (rather than *p++) to increment p.
35 (Lua_functions): Explicitely discard LOOKING_AT's return value.
36
37 2006-08-07 Masatake YAMATO <jet@gyve.org>
38
39 * etags.c (TEX_mode): Check getc retruns EOF.
40 File ended without newline causes infinite loop.
41
42 2002-07-14 Adrian Aichner <adrian@xemacs.org> (tiny change)
43
44 * etags.c: It's XEmacs, not Xemacs: change all the occurences.
45
46 2006-07-10 Francesco Potortì <pot@gnu.org>
47
48 * etags.c [ETAGS_REGEXPS]: #ifdef's deleted, define unconditionally.

63
64 2005-11-18 Hideki IWAMOTO <h-iwamoto@kit.hi-ho.ne.jp> (tiny change)
65
66 * etags.c (main): Cxref mode writes to stdout: do not close tagf,
67 which was never opened.
68
69 2005-09-27 Francesco Potortì <pot@gnu.org>
70
71 * etags.c: Preliminary Forth support.
72 (prolog_pr): Cast strlen to int before comparison.

83
84 * etags.c (main): When relative file names are given as argument,

97 (enum sym_type): New st_C_attribute value for parsing
98 gcc's __attribute__. Deleted st_C_typespec value.
99 (gperf, in_word_set): Use gperf 3, options changed. Added the
100 __attribute__ keyword, removed all the st_C_typespec keywords,

149 (consider_token, C_entries): Several bugs corrected that tagged
150 some declarations even though --declarations was not used.
151 (plainc): New macro.
152 (C_entries): Use it.
153 (C_entries): Several cosmetic changes.
154 (C_entries): Invalidate the token is some cases.
155
156 2002-08-29 Francesco Potorti` <pot@gnu.org>
157
158 * etags.c (C_entries): Corrected a problem with const C++ funcs.

182
183 2002-06-21 Francesco Potorti` <pot@gnu.org>
184
185 * etags.c (fdesc): New member `written'.
186 (readline, process_file): Initialise it.
187 (put_entries): Set it.
188 (main): Use it to create entries for files without tags.
189 (total_size_of_entries): Do not count invalid tags.

204 2002-06-20 Francesco Potorti` <pot@gnu.org>
205
206 * etags.c: Use, together with etags.el, an optimised form of tags,
207 which are almost always unnamed. etags.el looks for an explicit
208 tag name, then for an implicit one. See make_tag for details.
209 The change is both forwards and backwards compatible.
210 (make_tag): New function (was the disabled function new_pfnote).
211 (make_C_tag): Use it.
212

240 is now a modifier to the regexp. All callers changed.
241 (add_regex): Manage the regexp modifiers.
242 (regex_tag_multiline): New function. Reads from filebuf.
243 (readline_internal): If necessary, copy the whole file into filebuf.

246 2002-06-11 Francesco Potorti` <pot@gnu.org>
247
248 * etags.c (add_regex): Better check for null regexps.

255 2002-06-07 Francesco Potorti` <pot@gnu.org>
256
257 * etags.c (scan_separators): Support all character escape
258 sequences supported by gcc.
259 (find_entries): rewind unconditionally.
260 (find_entries): Do not call language functions directly, now calls
261 itself.
262 (find_entries): Do general initialisations here.
263 (CNL_SAVE_DEFINEDEF, C_entries, LOOP_ON_INPUT_LINES, F_getit)
264 (Ada_getit, Pascal_functions, Pascal_functions)
265 (prolog_skip_comment): Do not do them here.
266 (readline_internal): Increment lineno here.

287 (TeX_commands): Shorten the tag to the brace after the name.
288 (TeX_commands): Allow for names with embedded spaces.
289 (TeX_commands): Names now include the initial backslash.

291 (TeX_commands): Correct line char number in tags.
292 (TEX_tabent, TEX_token): Deleted.
293 (TeX_commands, TEX_decode_env): Streamlined.
294
295 2002-05-31 Paul Eggert <eggert@twinsun.com>
296
297 * etags.c (main): Use `sort -o TAGFILE TAGFILE' instead of
298 `sort TAGFILE -o TAGFILE', as POSIX 1003.1-2001 disallows
299 the latter usage.
300
301 2002-04-22 Francesco Potorti` <pot@gnu.org>
302
303 * etags.c: (last_node): Make it a global variable.
304 (process_file): Print the tags from the nodes as soon as

306 occupancy as etags to almost the same level as when the #line
307 directives were not parsed.

309 (find_entries): Use it.
310 (invalidate_nodes): In etags mode, do not just mark the nodes as

322 comparison if called with appropriate args.
323 (find_entries): Try with case insensitive match.
324 (process_file): Bug fixed.
325
326 2002-04-13 Francesco Potorti` <pot@gnu.org>
327
328 * etags.c (find_entries): Delete tags previously obtained from
329 file xxx.c's #line directives when parsing file xxx.y. This is
330 generally done for automatically generated files containing
331 #line directives. This handles the case when xxx.y is tagged
332 before xxx.c, and the entries of xxx.c pointing to xxx.y should
333 be discarded.
334 (language): Added the metasource member. Initializers changed.
335 (invalidate_nodes): New function.
336
337 2002-03-21 Francesco Potorti` <pot@gnu.org>
338
339 * etags.c (readline): Discard lines after having found a #line
340 directive pointing to an already tagged file. This handles the
341 case when xxx.y is tagged before xxx.c, and the entries of

343
344 2002-03-15 Francesco Potorti` <pot@gnu.org>
345
346 * etags.c (fdesc): New structure for keeping track of input files.
347 (fdesc): Remove `file' member (a string) and use instead a pointer
348 to a file description structure.
349 (curfile, curfiledir, curtagfname, curlang, nocharno,
350 forced_lang): Global variables removed in favor of fdhead and
351 curfdp, pointers to file description strucures.
352 (longopts, main, print_help): Use the CTAGS conditional to include
353 or exclude options that work on etags or ctags only.
354 (process_file, find_entries, pfnote, add_node, put_entries,
355 readline): Use fdhead and curfdp.
356 (process_file, find_entries): Do not take an arg string, all
357 callers changed.
358
359 2002-03-13 Francesco Potorti` <pot@gnu.org>
360
361 * etags.c (longopts, print_help, main): Test CTAGS to disallow
362 options that are not right for either etags or ctags.
363
364 2002-03-12 Francesco Potorti` <pot@gnu.org>
365
366 * etags.c (number_len, total_size_of_entries): Define them also
367 in CTAGS mode, because gcc does not compile all refs away.
368 (Python_functions, PHP_functions): Name tags, for ctags' sake.
369 (TeX_commands): Name tags. Correction of old disabled code.
370
371 2002-03-06 Francesco Potorti` <pot@gnu.org>
372
373 * etags.c (Python_functions): Consider indented "def" and "class".
374
375 2002-03-05 Francesco Potorti` <pot@gnu.org>
376
377 * etags.c (curfiledir, curtagfname): New global variables.
378 (process_file): Initialise them.
379 (readline): Canonicalize the name found in #line directive.
380
381 2002-03-05 Francesco Potorti` <pot@gnu.org>
382
383 * etags.c: Honour #line directives.
384 (no_line_directive): New global var; set it for old behaviour.
385 (main): Remove some #ifdef in the getopt switch.
386 (add_node, put_entries): Code added to merge different chunks of
387 nodes referring to the same file. Currently the tags are just
388 appended, without any check for duplicates.
389 (Perl_functions): Do not special case ctags.
390 (readline): Identify #line directives and do the right thing.
391 (nocharno, invalidcharno): New global vars.
392 (process_file): Reset nocharno.

400 (main): Call put_entries here even in CTAGS mode.
401 (main, process_file): Check the return values of fclose and pclose.
402 (process_file): Do not call put_entries after parsing each file.
403 (process_file): Canonicalise file names even for ctags.
404 (process_file): Set curfile here...
405 (find_entries): ... not here any more.
406 (add_node): In etags mode, build a linked list of entries (on
407 right pointer) for each file, and link the first entry of each
408 file on left nodes.
409 (put_entries): Print here the name of the file.
410 (put_entries): Print the entries starting from the first file.
411 (number_len, total_size_of_entries): Define these only iin etags
412 mode, make the second work only on the right nodes.
413
414 2002-01-03 Francesco Potorti` <pot@gnu.org>
415
416 * etags.c: Make all global variables static.

438 (Lisp_functions, L_getit): Clarified.
439
440 2001-12-17 Francesco Potorti` <pot@gnu.org>
441
442 * etags.c: [P_]: Renamed to __P for consistency with config.h.
443 [HAVE_CONFIG_H]: Let config.h deal with __P.
444 [__STDC__] [!HAVE_CONFIG_H]: Define PTR as in config.h.
445 [!__STDC__] [!HAVE_CONFIG_H]: Do not undefine static, because
446 gperf code needs it.
447 [HAVE_CONFIG_H] [!PTR]: Define PTR (for use with Xemacs).
448 [HAVE_CONFIG_H] [!__P]: Define __P (for use with Xemacs).
449 (xmalloc, xrealloc): Use PTR instead of long *.

468 [!HAVE_CONFIG_H] [!__STDC__]: #define const as the empty string.
469
470 2001-05-11 Francesco Potorti` <pot@gnu.org>
471
472 * etags.c (add_regex): Reset the whole newly allocated pattern
473 buffer instead of the individual members. It's safer and works

495 pcc wants to expand it as the token() macro even though it has no
496 arguments.

503 HAVE_CONFIG_H. This change only affects a standalone etags.
504 [WINDOWSNT]: #undef DOS_NT and #define it even if built with
505 HAVE_CONFIG_H. This change does nothing in Emacs, as DOS_NT is
506 always defined when HAVE_CONFIG_H and WINDOWS are both defined.
507 [!HAVE_UNISTD_H]: use defined(WINDOWSNT) instead of the bare
508 WINDOWSNT, as this is the correct way to use it.

582
583 * etags.c (iswhite): Redefined not to consider '\0' as white
