It supports Exuberant Ctags 59 and Universal Ctags. 60 61 [usage] 62 perl maps2conf.pl <ctags-path> <plugin-path> [<label>] 63 64 The default of <label> is 'default'. You can use this script to make 65 'gtags.conf' file for ctags plug-in parser. Please try this: 66 67 $ perl maps2conf.pl /usr/local/bin/ctags '$libdir/gtags/universal-ctags.la' >gtags.conf 68 $ gtags # use Universal Ctags as a parser 69 70 It assumed that '/usr/local/bin/ctags' above is Universal Ctags. 71 72 August 30 2017, Shigio YAMAGUCHI 73 74 [libutil/find.c] 75 In addition to the skip by regular expression, the following 76 files are skipped in ignore() function previously now. 77 o Files which start with '.' 78 o Tag files (GPATH, GTAGS, GRTAGS) 79 80 The regular expression is left, because xxx_filelist() functions 81 require it. 82 83 December 30 2016, Shigio YAMAGUCHI 84 85 Added taint mode to the following CGI scripts: 86 global.cgi.in 87 completion.cgi.in 88 89 December 21 2016, Shigio YAMAGUCHI 90 91 Rewrote the following functions without popen(3) in order not to cause 92 unnecessary security anxiety. 93 completion_idutils() 94 idutils() 95 96 These functions are called from CGI scripts of htags(1). 97 98 December 16 2016, Shigio YAMAGUCHI 99 100 Rewrote the following CGI scripts using perl5 syntax: 101 global.cgi.in 102 completion.cgi.in 103 104 There were many perl5.* incompatible with each other in the past. 105 Even then perl4 syntax always worked correctly. But this problem 106 was a thing of the past. Perl4 syntax is now meaningless. 107 108 October 22 2016, Shigio YAMAGUCHI 109 110 Removed the following files: 111 BOKIN_MODEL 112 BOKIN_MODEL_FAQ 113 114 BOKIN model was finished. Now GLOBAL is not a BOKINware. 115 116 October 8 2016, Shigio YAMAGUCHI 117 118 Added the following library source code. Though it's a GNU version, 119 I derived them from the latest Universal Ctags archive not to make 120 differences. 121 122 libglibc/fnmatch.c 123 libglibc/fnmatch.h 124 125 March 9 2016, Shigio YAMAGUCHI 126 127 Now, the following files in datadir are static. 128 - completion.cgi 129 - global.cgi 130 - jscode_suggest 131 - jscode_treeview 132 - style.css 133 134 February 3 2016, Shigio YAMAGUCHI 135 136 [Plug-in parser] 137 Added new plug-in parser 'universal-ctags.la'. 138 It is made using exuberant-ctags.c and -DUSE_EXTRA_FIELDS compile option. 139 140 [gtags.conf] 141 Added new entry 'universal-ctags'. 142 Added new variables 'ctagscom'. 143 144 [Plug-in interface] 145 Added new plug-in interface function getconf(). 146 You can access config variables of gtags(1) from plug-in parsers. 147 148 Nov 30 2015, Shigio YAMAGUCHI 149 150 Replaced @libdir_QUOTED@ with configuration variable in gtags.conf.in. 151 152 Nov 21 2015, Shigio YAMAGUCHI 153 154 Removed ctags-5.8.patch, because Universal Ctags supports reference tags 155 by itself now. 156 Added new test for Universal Ctags. 157 158 Oct 14 2015, Shigio YAMAGUCHI 159 160 [configure.ac] 161 Replaced @prefix_QUOTED@ with @libdir_QUOTED@ in gtags.conf.in. 162 From now on, you can use the --prefix, --exec-prefix and --libdir 163 options to set a value of @libdir_QUOTED@. This was done by Kevin Farshaw. 164 165 [libparser/parser.c] 166 Changed dynamic loading code using ld_dlopenext(). 167 (Fedora packaging guidelines prohibit .la files) 168 169 if (ld_dlopen('foo.la') == FAILED) 170 error_and_exit(); 171 | 172 v 173 if (ld_dlopen('foo.la') == FAILED) 174 if (ld_dlopenext('foo') == FAILED) 175 error_and_exit(); 176 177 From now on, extension of DLL is needless. 178 179 June 22 2015, Shigio YAMAGUCHI 180 181 To recover easiness of reading source code, removed Doxygen tags 182 in the source code except for the followings: 183 ('description' should be plain text) 184 185 /**< description */ 186 187 /** 188 * description 189 * @param[in] var description 190 * @param[out] var description 191 * @param[in,out] var description 192 * @return description 193 */ 194 195 November 10 2014, Shigio YAMAGUCHI 196 197 Included SQLite3 version 3.8.7.1 into 'libglibc'. 198 199 November 7 2014, Shigio YAMAGUCHI 200 201 Added support of Sqlite3 API for tag files (alpha quality). 202 If you will test the code then please do as follows: 203 204 [building phase] 205 $ ./configure --with-sqlite3 206 207 [executing phase] 208 $ gtags --sqlite3 209 210 June 28 2014, Shigio YAMAGUCHI 211 212 New environment variable GTAGSLOGICALPATH was added. 213 If it is set then GLOBAL use logical path (PWD), else 214 physical path. This variable is now undocumented. 215 216 March 17 2014, Shigio YAMAGUCHI 217 218 libutil/pathconvert.c module was divided into the following two modules: 219 o libutil/encodepath.c 220 o global/convert.c 221 According to the change, the function of the --path command of gtags(1) 222 (undocumented) was moved to global(1)'s --path-convert command. 223 224 December 18 2013, Shigio YAMAGUCHI 225 226 The following paths were removed from the candidate list of configuration file. 227 228 /etc/global.conf (OLD_GTAGSCONF) 229 /etc/gtags/global.conf (OLD_DEBIANCONF) 230 231 These paths were not documented once. 232 233 November 17 2013, Shigio YAMAGUCHI 234 235 Added two functions: copyfile(), copydirectory(). They remove the necessity 236 of external command 'cp'. 237 238 June 17 2013, Shigio YAMAGUCHI 239 240 Dependence to dbop.c module was eliminated from assoc.c module. 241 242 June 12 2013, Shigio YAMAGUCHI 243 244 File 'HTML/sitekey' (--system-cgi option) was removed since it is unnecessary. 245 246 December 11 2012, Shigio YAMAGUCHI 247 248 Some Automake macros were changed as follows to avoid warning messages. 249 o INCLUDES was changed to AM_CPPFLAGS 250 o AC_PROG_RANLIB was removed. 251 252 December 3 2012, Shigio YAMAGUCHI 253 254 [global/literal.c] 255 Included fgrep's code of 4.3BSD. 256 257 October 20 2012, Shigio YAMAGUCHI 258 259 Added support for type string of ctags. 260 Configure script detects whether ctags has --gtags option or not. 261 However, I don't know whether the ctags which has this option will be released. 262 263 Exuberant Ctags with --gtags option: 264 $ ctags --gtags -x ... 265 D main 320 global/global.c main(int argc, char **argv) 266 R NULL 325 global/global.c const char *av = NULL; 267 = 268 ^-- Type string (D: definition, R: other than definition) 269 270 October 13 2012, Shigio YAMAGUCHI 271 272 Comments were rewritten in the Doxygen style. Submitted by Simon Dommett. 273 To generate a document, please invoke make command in the root directory 274 of the project like follows: 275 276 $ make doxygen 277 278 doxygen 1.8.2 is required. 279 280 June 9 2012, Shigio YAMAGUCHI 281 282 Added BUILD_TOOLS file, which includes the list of version numbers 283 of the building tools used for building GLOBAL. It is automatically 284 generated by reconf.sh. 285 286 March 15 2011, Shigio YAMAGUCHI 287 288 Included cscope's source code. 289 290 [Added source files] [cscope-15.7] 291 m4/check_curses.m4 configure.in 292 gtags-cscope/manual.in doc/cscope.1 293 gtags-cscope/alloc.c src/alloc.c 294 gtags-cscope/alloc.h src/alloc.h 295 gtags-cscope/basename.c src/basename.c 296 gtags-cscope/build.c src/build.c 297 gtags-cscope/build.h src/build.h 298 gtags-cscope/command.c src/command.c 299 gtags-cscope/constants.h src/constants.h 300 gtags-cscope/display.c src/display.c 301 gtags-cscope/edit.c src/edit.c 302 gtags-cscope/exec.c src/exec.c 303 gtags-cscope/global-cscope.h src/global.h 304 gtags-cscope/gtags-cscope.c src/main.c 305 gtags-cscope/help.c src/help.c 306 gtags-cscope/history.c src/history.c 307 gtags-cscope/input.c src/input.c 308 gtags-cscope/library.h src/library.h 309 gtags-cscope/logdir.c src/logdir.c 310 gtags-cscope/mouse.c src/mouse.c 311 gtags-cscope/mygetenv.c src/mygetenv.c 312 gtags-cscope/mypopen.c src/mypopen.c 313 gtags-cscope/version-cscope.h src/version.h 314 315 February 4 2011, Shigio YAMAGUCHI 316 317 Configure.ac was modified to detect POSIX sort program automatically. 318 319 August 30 2010, Shigio YAMAGUCHI 320 321 Renamed the style sheet file in the source package from style.css to 322 style.css.tmpl, because to follow the custom of naming of other templates. 323 324 August 12 2010, Shigio YAMAGUCHI 325 326 Modification of the -S option. 327 328 o Renamed from '-S(--secure-cgi)' to '--system-cgi' because the 329 parameter is changed. 330 o Changed the site key directory from 'datadir' to 'localstatedir' 331 because 'datadir' is for read-only data. 332 o Changed the permission of the site key directory from 773 to 775. 333 334 These most was suggested by Ron Lee. 335 336 June 27 2010, Shigo YAMAGUCHI 337 338 Modification of the -S option. 339 340 1. New htags requires a unique key as the parameter of the -S option. 341 (It is a incompatible change.) 342 2. Htags makes a file whose name is the key in shared area, and 343 put the path of the HTML directory in it. 344 3. To make the file name unique, a key that already exists 345 is not allowed without --over-write option. 346 347 [in /var/src] 348 $ htags ... -S key1 349 ==== 350 | 351 +----------------+-----+ 352 v | 353 [/usr/local/share/gtags/sitekeys/key1] | 354 +-------------------------------- | 355 |/var/src/HTML | ...

(1) 361 ==== 362 363 The center CGI script can know the path of the HTML directory by the following 364 method. 365 366 (1) get a unique key from the variable 'id' 367 => 'key1' 368 (2) read directory name from '/usr/local/share/gtags/sitekeys/' + 'key1' 369 => '/var/src/HTML' 370 371 This mechanism conceals the real path name of the HTML directory. 372 373 May 21 2010, Shigo YAMAGUCHI 374 375 * Removed support for command layer plug-in parser(gtags-parser/). 376 377 May 20 2010, Shigo YAMAGUCHI 378 379 * Changed the architecture of gtags(1) from 2 pass to 1 pass. 380 381 [Old] 382 383 Pass 1: +-------+ 384 source files =============>| gtags |============> GTAGS 385 | |============> GPATH 386 | |============> temporary file 387 +-------+ 388 Pass 2: +-------+ 389 temporary file ============>| gtags |============> GRTAGS 390 GTAGS ============>| |============> GSYMS 391 +-------+ 392 [New] 393 394 Pass 1: +-------+ 395 source files =============>| gtags |============> GPATH 396 | |==>[sort]===> GTAGS 397 | |==>[sort]===> GRTAGS 398 +-------+ 399 (1) 1 pass architecture 400 GLOBAL doesn't use GSYMS any longer. Symbols stored there before are 401 put into GRTAGS instead. The divergence to GRTAGS and GSYMS is done 402 in referring stage (gtags_first() and gtags_next()) not in generating 403 stage. This change removes complexity from the program very much. 404 405 (2) Sorted writing 406 The (1) brings a big GRTAGS and decrease at the writing speed. 407 To avoid it, the records written to tag files are sorted beforehand. 408 This function becomes effective if DBOP_SORTED_WRITE flag is specified 409 for function dbop_open(). It uses an external POSIX sort program. 410 411 Note: In the new method, temporary file doesn't become unnecessary. 412 Because the external sort program also uses temporary files for its job. 413 414 This small work greatly depends on the big work by Hideki IWAMOTO on February 1 2010. 415 416 April 27 2010, Shigo YAMAGUCHI 417 418 * Changed the cache format (htags/cache.c) like follows: 419 420 (1) Duplicate tag file 421 +--------------------+ +---------------------+ 422 | <fid> <frequency>\0| -> | <fid>\0<frequency>\0| 423 +--------------------+ +---------------------+ 424 'D/<fid>.html' 425 (2) Tag definition 426 +---------------------------+ +----------------------+ 427 |<line number> <file name>\0| -> |<line number>\0<fid>\0| 428 +---------------------------+ +----------------------+ 429 'S/<fid>.html#<line number>' 430 431 March 8 2010, Shigio YAMAGUCHI 432 433 * Changed the default parser of gtags(1) from gtags-parser(1) to libgloparser.a. 434 Config parameter 'use_builtin_parser' is not used any longer. If the config 435 variable GTAGS is defined then gtags(1) use the command layer parser specified 436 by the variable as well as before. But it is obsolete. 437 438 February 27 2010, Hideki IWAMOTO 439 440 * Added support of function layer plugin parser. 441 Libtool 2.2.6b or later is required to build CVS version. 442 443 February 3 2010, Shigio YAMAGUCHI 444 445 * Use invisible temporary files instead of visible files (htags/assoc.c). 446 447 February 1 2010, Hideki IWAMOTO 448 449 * Added built-in parser to improve the performance of making tag files. 450 451 When the built-in parser is used, the source files are parsed only once. 452 The candidate of reference and other symbols are written to the temporary 453 file in Pass1, and read in Pass2. 454 455 Pass 1: 456 +-------+ 457 source files =============>| gtags |============> GTAGS 458 | |============> GPATH 459 | | tag record 460 | |============> temporary file 461 +-------+ 462 Pass 2: 463 tag record +-------+ 464 temporary file ============>| gtags |============> GRTAGS 465 | | 466 GTAGS ============>| |============> GSYMS 467 +-------+ 468 469 February 18 2009, Shigio YAMAGUCHI 470 471 * Rewrote the stack in libutil/find.c using the varray (libutil/varray.c) 472 instead of static array. 473 * Changed gtags(1) not to do useless inspection for the files in the 474 directories which are listed in the skip list. 475 476 September 27 2008, by Shigio YAMAGUCHI 477 478 * Changed the default cache size of DB library from 5M to 50M bytes. 479 * Recovered the code in which pread/pwrite is used in BSD db library. 480 However, this code is not automatically used. To include the code, 481 please invoke configure script with the --with-pread-pwrite option. 482 The original code was written by Hideki IWAMOTO. 483 484 July 14 2008, by Shigio YAMAGUCHI 485 486 * Changed gtags(1) to skip all files whoes first character of name is '.'. 487 488 The following path was deleted from the DEFAULTSKIP in configure.ac, since new 489 rule covers them. 490 491 .notfunction 492 .gdbinit 493 .cvsrc 494 .cvsignore 495 .gitignore 496 .cvspass 497 .cvswrappers 498 .deps/ 499 .snprj/ 500 .svn/ 501 .git/ 502 503 April 21 2008, by Shigio YAMAGUCHI 504 505 * gtags.vim: Stopped use of temporary file. 506 507 March 25 2008, by Shigio YAMAGUCHI 508 509 * gtags.vim, gtags.pl: rewritten using new '--from-here' option of global(1). 510 * Added htags/ghtml.cgi.tmpl. 511 * Described the method of apache setting as a comment in htags/global.cgi.tmpl.in. 512 * Modifications to allow symbolic link. 513 To realize it, normalize_path() and abs2rel() in libutil/abs2rel.c module is used 514 instead of realpath(3) library function. 515 * gtags.el and gtags.vim are rewritten using new '--from-here' option of global(1). 516 517 October 26 2007, by Shigio YAMAGUCHI 518 519 * Added file 'DONORS' which includes the list of donations to GNU GLOBAL. 520 * Idset module: Performance improvement of idset module by using "unsigned long" 521 instead of "unsigned int" for bitmask. This is necessary to use 64 bit processor 522 effectively. 523 524 July 6 2007, by Shigio YAMAGUCHI 525 526 * Migrated to GPLv3 and LGPLv3. 527 * gtags.conf.in: Migrated to simple all-permissive license. 528 529 May 5 2007, by Shigio YAMAGUCHI 530 531 * New files: BOKIN_MODEL, BOKIN_MODEL_FAQ, DONORS 532 533 March 10 2007, Shigio YAMAGUCHI 534 535 * gtags.el: Added (provide 'gtags). 536 * libutil/env.c: Use putenv(3) if it is available else use setenv(3). 537 Some systems don't have setenv(3). 538 539 January 29 2007, Shigio YAMAGUCHI 540 541 * Further compression of tag file (format version 5). 542 - Tag name is compressed. 543 - Each line number might be expressed as difference from the previous 544 line number except for the head. 545 ex: 11,3,2 means '11 14 16'. 546 - In addition, successive line numbers are expressed as range (n1-n2). 547 ex: 11-3 means '11 12 13 14'. 548 549 * global(1): Sort filter was moved from the output filter to the input filter. 550 551 ( input ) | ( m a i n ) | ( o u t p u t ) 552 gtagsop | global | tagsort | pathconvert 553 ---------------+---------------------+------------+-------------- 554 expand tag +------------+ sort tag convert path 555 | | 556 +-------------------------------------+ 557 v v 558 sort tag expand tag convert path 559 560 Instead, the processing of expanding tag was moved to the main module. 561 This improves the performance when compact format is used, since 562 sorting is done before expanding. 563 564 Recent architecture (GLOBAL-5.0 - 5.3) 565 566 +===========================================+ 567 |global(write)->[sort filter]->[path filter]|->[stdout] 568 +===========================================+ 569 570 New architecture (GLOBAL-5.4 -) 571 572 +===========================================+ 573 |[sort filter]->global(write)->[path filter]|->[stdout] 574 +===========================================+ 575 576 * Removed some code which call the following method: 577 putenv utimes 578 They are not natural method today. 579 pread pwrite 580 They are risky since they are not used so much and are not 581 often so tested. It was found that the pread and pwrite in cygwin 582 are buggy. Though it is not our business, user is not guilty too. 583 strdup 584 It is not needed since we use check_strdup() instead. 585 * Added some new modules. 586 pool - allocate and free memory for temporary use. 587 fileop - operation for opening and closing file. 588 * Added some new methods. 589 strmake module - strcmp_withterm() 590 * Removed some modules. 591 global/filter, libutil/tagsort 592 * idset module: 593 - Added new functions idset_first(), idset_next() and idset_empty(). 594 - Changed bitmask from char(8 bits) to integer (maybe 32 or 64 bits) 595 to improve performance. 596 597 November 20 2006, Shigio YAMAGUCHI 598 599 * gtags.el: 600 - gtags-make-complete-list is deprecated. 601 Added gtags-completing-gtags, gtags-completing-gsyms and gtags-completing. 602 - Throw away the output of gozilla in 'gtags-display-browser'. 603 604 August 8 2006, Shigio YAMAGUCHI 605 606 * htags/fileindex.c: Rewritten using recursive call instead of stack structures. 607 * gozilla.c: Fixed getURL() according to new GPATH. 608 * Replaced malloc(), realloc() and stdup() with check_xxxx() functions. 609 * Added icon files (icons/*png). 610 611 June 10 2006, Shigio YAMAGUCHI 612 613 * Recovered original texinfo file names (.txi -> .texi). 614 615 April 21 2006, Shigio YAMAGUCHI 616 617 Change in tag format: 618 * Moved to new tag format. New tag format is as follows. 619 GTAGS (with compress option) 620 <file id> <tag name> <line number> <compressed line image> 621 GRTAGS, GSYMS (with compact option) 622 <file id> <tag name> <line number>[,...] 623 * Now, GPATH has path names of not only source files but 624 also other text files. The following commands no longer 625 traverse file system. They read GPATH instead. 626 global(1) with the --other option. 627 htags(1) with the --other option. 628 629 Change in architecture: 630 * Changed the filtering architecture of global(1). 631 632 Old architecture (- GLOBAL-4.7.8) 633 634 process1 process2 process3 635 +=============+ +===========+ +===========+ 636 |global(write)|->|sort filter|->|path filter|->[stdout] 637 +=============+ +===========+ +===========+ 638 639 New architecture (GLOBAL-5.0 -) 640 641 1 process 642 +============================================+ 643 |global(write) ->[sort filter]->[path filter]|->[stdout] 644 +============================================+ 645 646 For the convenience of debugging, the old architecture is 647 also available. If macro EXTERNAL_FILTER is defined in filter.c 648 old architecture is selected. 649 650 The following options are also offered. (These options will be 651 deleted perhaps sooner or later.) 652 653 gtags --path={absolute|relative} --format={path|ctags|ctags-x|grep} 654 gtags --sort --format={path|ctags|ctags-x|grep} [--unique] 655 global --nofilter=[{path|sort}] 656 global --filter=[{path|sort}] 657 global --nosource 658 659 Moved the processing by which various formats are generated from 660 the main body of global(1) to the path filter. The main body 661 generates only two formats: path and ctags-x. 662 Path filter generates various formats which are given by the 663 --result=<format> option. 664 665 Change in CGI mechanism: 666 * The 'cgi-bin/' directory which generated by htags(1) doesn't 667 have any tag files. CGI script uses the tag files in the root 668 directory of a source project instead. 669 670 New modules: 671 * Added strhash module (strhash.c and strhash.h) to libutil. 672 Replaced the hash mechanism for compact format with this module. 673 * Added xargs module (xargs.c and xargs.h) to libutil. 674 Replaced the xargs(1) like mechanism with this module. 675 * Added pathconvert module (pathconvert.c and pathconvert.h) to libutil. 676 This module composes a part of an internal pipeline. 677 * Added tagsort module (tagsort.c and tagsort.h) to libutil. 678 Replaced external sort filter (gnusort) with internal one 679 (tagsort module). Gnusort was removed. As a result, GLOBAL 680 became free from dependence on external commands. 681 * Included GLIBC files obstack.c, obstack.h, hash-string.c and 682 hash-string.h. 683 684 Internal options: 685 * Removed two hidden options, --find and --other from gtags(1), 686 since they are no longer used. 687 * Added new internal format 'ctags-xid' of global(1). 688 The anchor generation method of the global.cgi was changed. 689 Global.cgi script was modified to use the --result=ctags-xid 690 option of global(1) 691 * Removed the -cc, -ccc, -cccc option of gtags(1). 692 These options were undocumented and only for testing. 693 * Removed two hidden options, --find and --other from gtags(1), 694 since they are no longer used. 695 696 Coding style: 697 * End of support of K&R. 698 * Changed function declarations to ANSI C style. 699 700 September 30 2005, Shigio YAMAGUCHI 701 702 * Updated GNU Free Documentation License.(1.1->1.2) 703 * Updated doc/texinfo.tex using texinfo-4.8. 704 * BSD advertising clause was deleted, according to the declaration 705 by UCB. 706 * Added new module idset. 707 * Added new function exec_line_limit() in env.c. 708 * Added new function find_open_filelist() for the --file=xxx option. 709 Find_read() and find_close() is shared by both find_open_filelist() 710 and find_open(). 711 * Added new config option --with-db185-compat[=DIR]. 712 This is not for normal use, but for debugging. 713 * Decreased use of popen() by moving the conversion from tabs to 714 spaces into htags. 715 * Reimplemented 'gtags --sort' without gnusort. 716 * The default cache size was changed from 500000 to 5000000. 717 Though I was assuming the machine equipped with 32-64MB, 718 in a recent machine, even small one has 256-512MB memory. 719 720 May 12 2005, Shigio YAMAGUCHI 721 722 * htags: New macro TOPDIR and SUBDIR added for readability. 723 * htags: Quoted the "&" in attribute value. 724 * Changed the address of FSF for each file. 725 726 April 19 2005, Shigio YAMAGUCHI 727 728 * htags: Added new functions to generate anchor tag. 729 For <a href=*** ...> 730 - gen_href_begin_with_title_target() 731 - gen_href_begin_simple() 732 - gen_href_begin() 733 - gen_href_begin_with_title() 734 - gen_href_end() 735 For <a name=***> 736 - gen_name_number() 737 - gen_name_string() 738 * htags, gtags-parser: Defined lex name generation rule. 739 - Change prefix * to *_. 740 - New lex name generation rule. 741 - New macro definition (LEXTEXT, LEXLENG, ...)) 742 * Added new macro STATIC_STRBUF(sb). 743 * Added new macros (PART_TAG, PART_LNO, PART_PATH, PART_LINE). 744 * strbuf.[ch]: Memory management was made more efficient. 745 * Added const prefix to char * if it is suitable. 746 * Install gtags.el into the $datadir/gtags directory instead of 747 the site lisp directory because the installation procedure 748 fails when the site lisp directory doesn't exist. 749 750 February 26 2005, Shigio YAMAGUCHI 751 752 * Required version of autotools was updated. 753 - Autoconf 2.59 754 - Automake 1.9.3 755 Configure.ac was modified according to the new style. 756 * Install gtags.el into the site lisp directory. 757 * When child process terminates abnormally, the program 758 execution is ended. 759 * The gctags directory was renamed to gtags-parser according to 760 the renaming of the command. 761 * gtags-parser: Modified to use a switch table for switching 762 language. 763 764 November 11 2004, Shigio YAMAGUCHI 765 766 * Assembly language parser rewritten using Yacc. 767 * libutil/strmake.c: strtrim() added. 768 * libutil/varray.c added. 769 770 Decrease in dependency to external commands: 771 * The sed(1), sort(1) and find(1) are not necessary any longer. 772 * The support of find(1) as a method of directory traversing 773 was ended. As a result, dirent(3) became indispensable. 774 The configuration phase was changed like follows: 775 776 if dirent(3) exist then 777 use dirent(3) 778 else if find(1) exist then 779 use find(1) 780 else 781 ERROR 782 | 783 v 784 if dirent(3) exist then 785 use dirent(3) 786 else 787 ERROR 788 * Htags.pl was removed completely. Therefore, the --date, --pwd, 789 --write and --scandb option of gtags(1) which was used internally 790 by htags.pl, were removed. 791 * Includes GNU sort as part of GLOBAL package. 792 This solves following troubles: 793 - A certain operating system has another 'sort' command 794 that specification is different from GNU sort. Unluckily, 795 the command is often invoked for GLOBAL. 796 - Multi-language version of sort is often very slow. Since GLOBAL 797 doesn't support multi-language, the slowness is quite meaningless. 798 - In the past, the specification of sort command was changed. 799 800 October 6 2004, Shigio YAMAGUCHI 801 802 * libutil/langmap.c, langmap.h added. 803 Config variable 'langmap' will be added officially sooner or later. 804 * gctags/asm_res.in and htags/asm.l added. 805 * fileindex.c: makeincludeindex() was cut out from makefileindex() 806 for statistic. 807 * The priority of the method selection for directory traversing 808 was changed like follows: 809 810 if find(1) exist then 811 use find(1) 812 else 813 use dirent(3) 814 | 815 v 816 if dirent(3) exist then 817 use dirent(3) 818 else if find(1) exist then 819 use find(1) 820 else 821 ERROR 822 823 * gozilla: removed the Win32 version of sendbrowser, using a direct 824 call to ShellExecute (since the browser probably isn't on the path, 825 and -remote doesn't seem to work on Windows). 826 * htags/src2html.c: Modified to use a switch table for switching 827 language. 828 829 August 26 2004, Shigio YAMAGUCHI 830 831 * Moved function now() from gtags.c to libutil/date.c. 832 * htags: Changed so that the path passed to CGI might be encoded to %xx. 833 * htags: Rewritten in C language. 834 * htags: The use of the 'gtags --write' was stopped. 835 * die.c: New function sethandler() and warning() added. 836 * gctags/reserved.pl: The use of the --key-positions option of gperf(1) 837 was stopped. We need gperf-3.0.1 instead. 838 839 June 1 2004, Shigio YAMAGUCHI 840 841 * htags: Function usable() was changed to the same specification 842 as usable() in libutil/usable(). 843 * htags: Execution path of global(1) was changed to the absolute path. 844 * htags: Write FILEMAP file for reference from external system. 845 * conf.c: New config variable 'bindir' and 'datadir' added. 846 * w32/ directory removed. 847 848 Feb 1 2004, Shigio YAMAGUCHI 849 850 * Rewrite strbuf_putn() without snprintf(). 851 * Created datadir, the default is '/usr/local/share/gtags'. 852 The following files are installed into the directory: 853 AUTHORS COPYING ChangeLog FAQ INSTALL LICENSE NEWS README THANKS 854 globash.rc gtags.conf gtags.el gtags.pl gtags.vim nvi-1.79-gtags.diff 855 856 Oct 3 2003, Shigio YAMAGUCHI 857 858 * gtags.conf.in, libutil/conf.h.in: Now gtags.conf and conf.h 859 are generated by Autoconf. 860 * The priority of the method of directory traverse was reversed again, 861 because, in some GNU/Linux, struct dirent has a member d_type but 862 always return 0. As the result, if find(1) is available then use it, 863 otherwise use dirent(3). 864 865 July 2 2003, Shigio YAMAGUCHI 866 867 * gctags: If you want to build this parser from original source in 868 CVS repository then it is necessary to install flex(1) and gperf(1) 869 in your environment. (Since both of them are GNU software, 870 you can get them from GNU ftp site.) 871 * reserved.pl: Generate C and Perl code for locating reserved words. 872 * gtags.c: The --createdb and the --readdb option which used for anchor 873 database were removed, because there is no necessity any longer. 874 875 June 5 2003, Shigio YAMAGUCHI 876 877 * libutil/env.c: replace putenv() and setenv() with set_env(); 878 * libutil/char.c,char.h: New files. 879 * libutil/find.c: Skip symbolic links to eliminate the difference 880 between find(1) version and dirent(3) version. 881 * htags.in: Remove tag name and line image from cache record. 882 This made cache file smaller. 883 * htags.in: Stop using anchor db. Up to now, only gtags had called 884 the parser. But hereafter, the parser will be called by both 885 gtags and htags. 886 * global.c: About the -g option, implementation using grep + xargs 887 was removed. 888 * libutil/find.c: The priority of the method of directory traverse 889 was reversed. If dirent(3) is available, then use it to traverse 890 directory tree. Otherwise use find(1). 891 * configure.ac: --with-cflags=[=VAL] was removed. 892 Please use ./configure CFLAGS=VAL instead. 893 * reconf.sh: --configure, --make and --install option added. 894 895 March 29 2003, Shigio YAMAGUCHI 896 897 * C.c,Cpp.c: move some code into condition_macro. 898 * C.h, Cpp.h, java.h: replace #define macro with enum member 899 for representing reserved words. 900 * htags.in: add reserved words. 901 * htags/manual.in: add description about configuration variable 902 'table_begin' and 'tabel_end'. 903 * htags.in, manual.in: add configuration variables 904 'colorize_warned_line', 'warned_line_begin', 'warned_line_end'. 905 * dbop.c: environment variable GTAGSCACHE added. 906 907 November 9 2002, Shigio YAMAGUCHI 908 909 * gtags.c: --convert/--createdb/--readdb/--scandb option added. 910 * btreeop: replaced with gtags and removed. 911 * split.c: use SPLIT structure which manage sub-string. 912 * gtagsop.c: now format version is 3 (pathindex format). 913 * configure.ac: fixed for Autoconf-2.53 and renamed. 914 * acconfig.h: removed because it is considered to be obsoleted. 915 * gctags: inittable() added for each parser, which set up reserved 916 word table. 917 * doc/*.texi: renamed from *.texi to *.txi for djgpp. 918 * libutil: linetable.[ch] added. 919 920 July 4 2002, Shigio YAMAGUCHI 921 922 * gctags.c: allows second argument in *ENTRY for 4.3BSD. 923 * split.c: splitting function added. 924 * strlimcpy.c: replaced strcpy() and strncpy() with strlimcpy(). 925 * strbuf.c: strbuf_putn() added. 926 * conf.c find.c: shut buffer overflow. 927 * gtags, htags: './' removed from path name in verbose message. 928 * *.c, *.h: copyright year fixed. 929 * configure.in: macro AG_BYTE_ORDER recovered. 930 * htags: sort command replaced with gtags --sort in makedupindex() 931 so that sort can treat smaller number of tag lines. 932 * htags: makedupindex() rewritten for performance. 933 934 March 30 2002, Shigio YAMAGUCHI 935 936 * conf.c: added GPATH,GTAGS,GRTAGS,GSYMS,tags,TAGS,ID to DEFAULTSKIP. 937 * find.c: decreased dependency on find(1). 938 removed length argument from find_read(). 939 * global.texi: documentation reconstructed. 940 * globash.rc: --no-wait option added to emacsclient. 941 * gozilla: gozilla directory added. 942 * abs2rel.c: added for path conversion. pathfilter with sed(1) 943 is replaced gtags(1) --relative or --absolute. 944 * global: use lid(1) rather than gid(1). 945 * usable.c: locate command for BINDIR before PATH. 946 * htags: bless.sh remove cgi-bin/global.cgi because it is not needed. 947 * htags: changed open into 'open + exec' to avoid command substitutions 948 in pattern. 949 950 January 22 2002, Shigio YAMAGUCHI 951 952 * htags: build trouble fixed. 953 global.cgi wasn't generated correctly. 954 955 January 10 2002, Shigio YAMAGUCHI 956 957 * DJGPP support code added. 958 Jason Hood ported Global-4.0.1 into DJGPP environment. 959 I have merged his code into this version. 960 * gtags.pl added. 961 * Convert.pl added. From now on, usage, help, man, info are 962 generated automatically by this script from */manual.in files. 963 * gtags, global: make exit code rule: 964 0:normal, 1:exception, 2:usage, 3:GTAGS not found. 965 966 November 23 2001, Shigio YAMAGUCHI 967 968 * gtags: format char for strftime() changed (%e -> %d). 969 * gtags: the path of gctags changed from 'gctags' to '$bindir/gctags'. 970 * htags: use gtags --date and gtags --pwd instead of date and pwd. 971 Above changes are for Windows 32 environment. 972 * rename file: pathop.[ch] -> gpathop.[ch]. 973 * rename functions: pathxxx -> gpath_xxx, gtagsxxx -> gtags_xxx. 974 * rename functions: ffindxxx -> find_xxx, gfindxxx -> gfind_xxx. 975 * libglibc/snprintf.c added. 976 * move gfind_xxx from libutil/find.c to libutil/gpathop.c. 977 978 July 31 2001, Shigio YAMAGUCHI 979 980 * VERSION: removed. 981 * compat.h: moved to libdb/. 982 * machine/: removed. 983 * htags: WWW link in hypertext was modified. 984 * gtags.c, global.c: rewrite code for putenv(3) using malloc(3). 985 986 July 12 2001, Shigio YAMAGUCHI 987 988 * config variable HAVE_SNPRINTF and AC_FUNC_ALLOCA added. 989 * stop using MAXENVLEN because it brings buffer overflow. 990 * htags.pl: the value of id changed from src directory 991 to HTML directory. 992 * libutil/conf.c: error check added. 993 * libutil/gtagsop.c: replace notnamechar() with isregex(). 994 * put '#assert' into reserved word. 995 * reconf.sh: command for generating configure added. 996 * Copyright notice added for short files that are not important 997 enough to worry about copylefting. 998 * libdb/db.h: typdefs pgno_t, indx_t and recno_t changed into macros. 999 * gctags/{C.c,Cpp.c}: memory violation fixed. 1000 * libutil/getopt* and libregex/* moved to new libglibc/ directory. 1001 1002 September 26 2000, Shigio YAMAGUCHI 1003 1004 * htags.pl: use generated path of perl for global.cgi. 1005 * global.1, htags.1, btreeop.1: fix missing .El. 1006 * make version number 'major.minor.fixed'. 1007 1008 September 3 2000, Shigio YAMAGUCHI 1009 1010 * license changed from BSD-style to GPL. 1011 * now generated automatically by Automake and Autoconf. 1012 * nvi-1.79-gtags.diff: put into the public domain. 1013 * htags.pl: command path in global.cgi becomes generated 1014 at execution time. usable() changed to return path. 1015 * htags.pl: optimized about temporary database. 1016 * htags.pl: most code which depend on javascript are removed 1017 because most of browsers don't support the language. 1018 * mgets.c: now belongs strbuf.c as strbuf_fgets(). 1019 * strbuf.c: new argument 'initial buffer size' of strbuf_open(). 1020 * global.conf: one line script for ctags-exuberant fixed. 1021 * Cpp.h, java.h: MAXCLASSSTACK changed from 10 to 100. 1022 * use snprintf(3) instead of sprintf(3). 1023 * replace Henry Spencer's regex(3) with GNU's one. 1024 * gctags/C.c: ignore 'extern' to treat 'extern func() { ...}'. 1025 * global.c: use grep(1) if grep and xargs(1) are available. 1026 * global.c: use find(1) if find is available. 1027 * gtags.el: re-implement as a minor mode (gtags-mode) and 1028 a major mode (gtags-select-mode) to work with other major mode 1029 like c-mode. 1030 prefix 'gtags-' added to all functions to avoid conflicts with 1031 other packages.. 1032 1033 December 23, 1999, Shigio YAMAGUCHI 1034 1035 * htags.pl: change the process of removing cache file. 1036 * global.c, gtagsop.c, dbop.c: processing of regular expression 1037 is moved from command level (global.c) to library level 1038 (gtagsop.c) for optimizing -s option. 1039 * find.c: gfindopen(), gfindread(), gfindclose() added for 1040 optimizing -g option. 1041 1042 November 3, 1999, Shigio YAMAGUCHI 1043 1044 * htags: stop memory cache. 1045 * token.c: change buffer type from char to unsigned char. 1046 1047 September 17, 1999, Shigio YAMAGUCHI 1048 1049 * compat.h: macro for solaris added. 1050 * Makefile.bsd: delete libregex.a target because BSD has it in libc. 1051 1052 August 29, 1999, Shigio YAMAGUCHI 1053 1054 * gozilla: add DDE communication code in Windows 32. 1055 1056 August 26, 1999, Shigio YAMAGUCHI 1057 1058 * Cygwin support code added. 1059 David Aspinwall ported Global-3.44 into cygwin32 environment. 1060 I referred his code but I didn't use it in as is style, because it 1061 conflicted against Dan Fandrich's Windows 32 code. I wrote new 1062 code for cygwin32 borrowing David's idea. 1063 So any bugs in this area are therefore my fault, not David's. 1064 * htags: stop using cp(1). 1065 1066 August 23, 1999, Shigio YAMAGUCHI 1067 1068 * Windows 32 support code added. 1069 Dan Fandrich ported Global-3.44 into Windows 32 environment. 1070 I have included his code into this version (3.5) and altered them 1071 for some (mainly licensing) reasons, so any bugs in this area 1072 are therefore my fault, not Dan's. 1073 * copyright notice of Tama Communications Corporation added. 1074 * Henry Spencer's regex(3) imported. 1075 * gtags.el: now detect XEmacs. 1076 * htags: rewrite header #!/usr/bin/perl -> #!/usr/bin/env perl 1077 * find.c: USEFIND undefined by default. 1078 1079 March 22, 1999, Shigio YAMAGUCHI 1080 1081 * htags: internal path changed for ISO9660 file system. 1082 * htags: --action=url, --id=id and --nocgi options added to realize 1083 Ron Lee's htmake. (internal use only - undocumented) 1084 * Makefile.generic: DESTDIR macro added. 1085 * db(3) 1.85 imported to keep machine independence in generic make. 1086 'dbpatches' already has been applied. 1087 1088 January 20, 1999, Shigio YAMAGUCHI 1089 1090 * wrong copyright notice fixed.
