GNU Global NEWS - User visible changes.
At least, you should search '[INCOMPATIBLE CHANGES]' for each version.

Version 6.6.15 -  June 15, 2026

[INCOMPATIBLE CHANGES]
o global(1): Now "--path-style=through" option ignores
  GTAGSLIBPATH environment variable. The original purpose of this
  option was to allow external programs to do the path manipulation
  that global(1) does. However, it has no meaning in library paths.

[FIXED BUGS]
o universal-ctags.la: This plug-in parser was broken by ctags
  settings. For example, the following setting will prevent the
  parser from processing C language.

  [~/.ctags.d/any.ctags]
  +----------------------
  |--languages=-C
  +----------------------

  Now it works. The --languages option is ignored when used under
  gtags(1).

Version 6.6.14 -  December 11, 2024

[CHANGES]
New functions:
o gtags: Added support for 'record' (java).

Version 6.6.13 - July 2 2024

[FIXED BUGS]
o htags: took the input provided in the dbpath option (-d) and
  appended it to a command string that will later be executed by
  system() function, without any escaping, leading to a command
  injection vulnerability (CVE-2024-38448).

	$ rm -f /tmp/w
	$ htags -g -q -d '$(pwd>/tmp/w)'
	$ cat /tmp/w
	/tmp/global/htags

  Now it just outputs an error:

	$ rm -f /tmp/w
	$ htags -g -q -d '$(pwd>/tmp/w)'
	gtags: directory '/tmp/global/htags/$(pwd>' not found.
	$ cat /tmp/w
	cat: /tmp/w: No such file or directory

o gtags: Pygments plug-in parser with Python3 does not work,
  if 'ctagscom' is not set. If it is not set, default path obtained
  by configure script should be used.
        
	$ cat > gtags.conf
	default:\
		:ctagscom=:\
		:langmap=C\:.c.h:\
		:gtags_parser=C\:/usr/local/lib/gtags/pygments-parser.la:
	$ gtags
	$ global -x '.*'
	$ _                             # no tags

	Now it works.

Version 6.6.12 - March 5 2024

[CHANGES]
global: Added new option 'limit' for the --completion command.
  If limit option is given, print up to the limit lines.
	$ global --completion=100 -P lib

[FIXED BUGS]
o global: The -c command with the --from-here option brings segmentation fault.
	$ global -c --from-here='158:libutil/find.c'
  Now it works (--from-here is ignored).

o htags: If the environment happens to be large, it fails with an obscure
  error message:
	$ htags ...
	htags: Negative exec line limit = -80951
  Now it mostly works since the limit has been loosened.

Version 6.6.11 - November 20 2023

[CHANGE IN SUPPORT STATUS]
Exuberant Ctags as a plug-in parser is no longer supported.
Please use Universal Ctags 6.0.0 or later instead. The same
applies to Pygments plug-in parser.

[FIXED BUGS]
o gtags('pygments-parser.la'): The following setting of Universal Ctags
  caused no tag output. Same result if the value is not 'no'.

        [$HOME/.config/conf.ctags]
        +---------------------------
        |--tag-relative=always

  Now it works.

Version 6.6.10 - May 9 2023

[INCOMPATIBLE CHANGES]
o configure: Auto-detection of python in the config stage is no longer done.
  '$datadir/gtags/script/pygments_parser.py' will have '#!/usr/bin/env python' by default.
  You can specify the path using the following option:
  (Assuming python is located in /usr/local3/bin)

	./configure --with-python-interpreter=/usr/local3/bin/python

o configure: The --with-pread-pwrite option no longer exists.
  Now configure automatically uses pread(2) and pwrite(2) if they are available.

[FIXED BUGS]
o gtags(C++ parser): did not recognize 'namespace name1::name2::name3' syntax.
  Now it picks up 'name2' and 'name3' in addition to 'name1' in the next example:

	namespace name1::name2::name3 { /*...*/ }

o gtags('universal-ctags.la'): The following setting of Universal Ctags caused no tag output.
  Same result if the value is not 'no'.

	[$HOME/.config/conf.ctags]
	+---------------------------
	|--tag-relative=always

  Now it works. This fix applies to 'exuberant-ctags.la' as well.

Version 6.6.9 - December 12 2022

[FIXED BUGS]
o gtags(C++ parser): did not recognize 'final' keyword. Now it works.
o Fixed a couple of bugs in MinGW.
- Fixed unknown type sigset_t error in MinGW.
- Fixed pointer to integer cast warnings in MinGW.

Version 6.6.8 - December 17 2021

[CHANGES]
o gtags: Now you can write comments in '.notfunction' file.
  Lines starting with ';' are comment lines.

	[.notfunction]
	+---------------------------
	|;
	|; This is a comment.
	|;
	|main

o configure: Now you can build Global with external SQLite3 library.
  --with-sqlite3[=dir]    By default, the embedded version is used.

[NEW DOCUMENT]
o plugin-factory/PLUGIN_HOWTO.universal-ctags:
  Added a howto document: 'How to get Universal Ctags to handle references'

[FIXED BUGS]
o global: The --print0 option was ignored when using the --completion command.
  Now it works.
o gtags: The --file option could cause segmentation fault.
  Now it works.

Version 6.6.7 - July 1 2021

[FIXED BUGS]
o Pygments-enabled gtags failed to start. Now it works.
  (Changed the shebang of pygments_parser.py.in from '#!/usr/bin/env python'
  to '#!@PYTHON@'.)

Version 6.6.6 - May 2 2021

[CHANGES]
New facilities:
o gtags.el: Added native support for TRAMP.
  'global-client' command is no longer needed to use TRAMP.

  Required:
    GNU Emacs version 25.1 or later (Tested on version 26).
    If you don't use 'gtags-visit-rootdir' then version 22 is good enough.
    You also need to install Global at the remote site.
  Limitations: gtags-path-style: 'root is automatically converted to 'relative.

o gtags.el: New custom variable 'gtags-path-order'.
  value: 'alphabet (default) or 'nearness.

[DEPRECATED]
o gtags: environment variable GTAGSFORCECPP is deprecated.

[FIXED BUGS]
o configure: configure script failed with an error 'realpath not found.' on MacOS 11.1.
  Now, it works.
o gtags: If GTAGSFORCECPP was defined and --explain was used and the first file is a
  '*.h', gtags crashed. Now it works.

Version 6.6.5 - September 3 2020

[INCOMPATIBLE CHANGES]
o gtags: Now gtags_hook is not executed when the following options are specified:
  --version, --help, --config, --dump.
  This change might be considered a bug fix.

[CHANGES]
New facilities:
o gtags: Added new option: -C (--directory)
  Change the directory before doing all the work including parameter analysis.

[DEPRECATED]
o gtags: the built-in C++ parser is deprecated, since it is not well maintained.
  Currently, it is hard to say that Global supports C++ language.

Version 6.6.4 - December 24 2019

[INCOMPATIBLE CHANGES]
o htags: Now the -g, --suggest and --suggest2 option does not make ID
  database, since mkid(1) often fails on some systems. If mkid works
  in your system, you can use ID database by the following command line:
	$ gtags -I		# create ID database explicitly
	$ htags --suggest2

[CHANGES]
New facilities:
o gtags.vim: New custom variable 'Gtags_Emacs_Like_Mode'.
  If this variable is 1, use the tag files of the project to which the current
  file belongs. By default, use the tag files of the current project.

[FIXED BUGS]
o gtags.vim: Gtags command discarded all unsaved changes. Now it brings
  the following error: E37: No write since last change (add ! to override).
o gtags: Now gtags skips java annotations (@...[(...)]).

Version 6.6.3 - December 17 2018

[CHANGES]
New facilities:
o gtags: New --skip-symlink option.
  This option skips symbolic links.
  --skip-symlink[=type]
  If type is 'f' then skip only symbolic links for file, else if 'd' then skip
  only symbolic links for directory. The default value is 'a' (all symbolic links).
o gtags-cscope: 'Find assignments to this symbol:' was implemented.
  In vim, you can use it as ':cs find a <pattern>' or ':cs find 9 <pattern>'.
o gtags-cscope.vim: the following key assignment was added.
	<C-\>a, <C-@>a, <C-@><C-@>a

[FIXED BUGS]
o pygments_parser.py.in: This plug-in parser failed with the handling of file names
  with mixed case on Windows. Now it works.
o gtags-cscope: Fixed a wrong description in the online manual.
  Find this function definition: -> Find this global definition:

Version 6.6.2 - February 9 2018

[INCOMPATIBLE CHANGES]
o gozilla: Deleted the following undocumented functions to reduce or eliminate
  possibility of future security risks. These were inherently unnecessary as
  source code tagging system.

  $HOME/.gozillarc
        Alias file. Please read the source code for details.
  BUGS
        Gozilla can accept not only source files but also text files,
        directories, HTML files and even URLs, because it is omnivorous.

[FIXED BUGS]
o geco.rc: gecoless always failed with a message 'geco: percol, peco or fzf is required.'
  Now, it works.
o gtags-cscope: did not accept function '9' in the line mode. This caused vim8 to hang.
  Now it accepts function '9' and reports an error message.

Version 6.6.1 - December 16 2017

[FIXED BUG]
o gozilla: A critical vulnerability (CVE-2017-17531) was found in a unknown
  function of gozilla(1). It allows remote attackers to execute arbitrary
  code via a crafted URL. All gozilla(1) before Global-6.6.1 have the vulnerability.
  Now it is fixed.

- What is the unknown function?
Gozilla accepts a URL as an argument, and invokes a web browser with the URL.
Though it is undocumented, it is implied in the online manual as follows:

> BUGS
>         Gozilla can accept not only source files but also text files,
>         directories, HTML files and even URLs, because it is omnivorous.

Version 6.6 - December 12 2017

[CHANGES]
New facilities:
o gtags: Added support for glob patterns in langmap variable in gtags.conf(5).
  Now, you can treat source files without extension like ctags(1).
  (e.g. :langmap=Make\:.mak.mk([Mm]akefile):)

Changed:
o gozilla: Changed the default browser from 'mozilla' to 'firefox'.
o gtags.conf.in: Updated to adapt to the latest ctags(s).
  Removed: common-ctags-maps
  Updated: exuberant-ctags, universal-ctags

[INCOMPATIBLE CHANGES]
o universal-ctags.la: The --extra option in Exuberant-ctags is renamed
  to --extras (plural) in Universal-ctags for making consistent with
  --kinds-<LANG> and --fields.

[FIXED BUGS]
o gtags: (parser error) picked up a typedef name as both of definition
  and reference. Now it works.
	Input:
	[a.h]
	typedef struct a A;

	$ global -x A
	A                   1 a.h              typedef struct a A;
	$ global -x A -r
	(global-6.5.7)
	A                   1 a.h              typedef struct a A;
	(global-6.6)
	no output

o global: the -i option does not work correctly in some conditions.
  Now it works.
o global: didn't accept pattern as a string literal with the --from-here
  option, even if the --literal option was specified. Now, global(1)
  accepts pattern as a string literal with the --literal option.
o libdb: there was 4 Gbyte limitation on the system where `off_t' is 64 bits
  and `long' is 32 bits. Now it is eliminated.
o libparser: php parser was not reset state for each source file.
  So, it was producing unintelligible results. Now it is fixed.
o gozilla: with wrong argument caused segmentation violation.
	$ gozilla -d
	Segmentation fault: 11
  Now it displays usage.

Version 6.5.7 - 15 May 2017

[CHANGES]
o global: Now global(1) accept a file as --nearness option.
  If it is a file, tags in the file are shown first.
o global: Added aliases for MAKEOBJDIR and MAKEOBJDIRPREFIX.
  GTAGSOBJDIR: alias for MAKEOBJDIR
  GTAGSOBJDIRPREFIX: alias for MAKEOBJDIRPREFIX
  These aliases are given higher priority than the originals.
o global: New command --print=<name>.
  <name> may be one of: root, dbpath or conf.
  This is a generic version of the -p (--print-dbpath) command.
	'global -p' is equal to 'global --print=dbpath'
	'global -pr' is equal to 'global --print=root'
o gtags: Updated the built-in PHP parser to support namespaces and traits,
  which were introduced in PHP5. The following keywords have been removed:
	- failure: not a keyword
	- header: normal built-in function
	- is_array: normal built-in function
	- is_set: typo -> isset
	- printf: normal built-in function
	- setcookie: normal built-in function
	- success: not a keyword

[FIXED BUGS]
o globash: Echo command with -n option didn't work on some OS. Now it works.
o global: The --nearness option without -x option brought segmentation fault.
	$ global --nearness=. main
	Segmentation fault: 11
  Now it works.
o global: --from-here with -i option did not ignore case of function name
  in the context. Now it works.
	Input:
	[main.c]
	1: main() {
	2:         func();
	3:         Func();
	4: }
	5: func() {}
	6: Func() {}

	$ global -xi --from-here=6:main.c func
	(global-6.5.6)
	Func                6 main.c           Func() {}
	func                5 main.c           func() {}
	(global-6.5.7)
	Func                3 main.c            Func();
	func                2 main.c            func();

[INCOMPATIBLE CHANGES]
o gtags.conf: Added new candidate path.
        (1) --gtagsconf file
        (2) $GTAGSCONF
        (3) [project root]/gtags.conf
        (4) [project root]/[objdir]/gtags.conf       <- [NEW]
        (5) $HOME/.globalrc
        (6) /etc/gtags.conf
        (7) [sysconfdir]/gtags.conf

        The default of [objdir] is 'obj'. You can change it by
        the environment variables (GTAGSOBJDIR or MAKEOBJDIR).

Version 6.5.6 - December 19 2016

[CHANGES]
New facilities:
o htags-server: New --retry[=n] option.
  If the port is already in use, retry n times with incrementing the port number.
  The default of n is 20.
o htags: Changed the format of function header (--show-position) to make copying
  text easier.
o geco.rc: Added 'fzf' as a selector candidate.
o gtags: New configuration variable 'gtags_hook'.
  gtags_hook=<command line>
	Specify a command line which should be executed at the beginning of gtags(1).
	Leading "./" in any path is always means the project root directory, since
	gtags(1) is always invoked there.
  GTAGS_COMMANDLINE environment variable (read only)
	You can get the effective command line of gtags(1) from the hook. It includes
	both $GTAGS_OPTIONS and real arguments.

   [Usage]
   You can update 'gtags.files' before gtags(1) read it.

	[gtags.conf]
	+----------------------------------------
	|...
	|:gtags_hook=find src lib -print >gtags.files:

   You can refer the effective arguments of gtags(1) from the hook using
   environment variable GTAGS_COMMANDLINE.

	[gtags.conf]
	+----------------------------------------
	|...
	|:gtags_hook=./gen.sh:\
	|:GTAGS_OPTIONS=-c:\

	[gen.sh]
	+----------------------------------------
	|#!/bin/sh
	|echo ">>> $GTAGS_COMMANDLINE"		# show effective command line

	$ gtags -O
	>>> gtags -c -O
	$ _

[INCOMPATIBLE CHANGES]
o htags: Now --cvsweb option always insert 'view=log' to the generated URLs.
  Because it seems to be almost always a desirable specification.

[FIXED BUGS]
o gtags: Gtags often aborts with a message "buffer overflow. strlimcpy" when
  it encounters a long token (> 152 bytes). Now gtags always ignores it with
  a message "symbol name is too long. (Ignored)".
o htags: Old packages included two CGI scripts (completion.cgi, global.cgi)
  generated in the release manager's machine by mistake. They have some literal
  path like '/opt/local/bin/perl' which works only with MacPorts.
  Now, they are generated in the target (your) machine.

Version 6.5.5 - Sep 21 2016

This is a bug fix release.

[FIXED BUGS]
o exuberant-ctags.la: The path name of ctags command couldn't changed.
  Now, it can be changed by configuration variable 'ctagscom'.
o Tag files got corrupted when the built-in C++ parser gave up parsing and aborted.
  Now, it is avoided.

o Some inappropriate error messages were changed.

  Error1: NULL file (file size == 0)

	$ cp /dev/null GTAGS
	$ global -x main

	(Global-6.5.4)	global: /tmp/test/GTAGS seems older format. Please remake tag files.
	(Global-6.5.5)	global: /tmp/test/GTAGS seems to be corrupted.

  Error2: Corrupted file

	$ echo aaa >GTAGS
	$ global -x main

	(Global-6.5.4)	global: GTAGS not found.
	(Global-6.5.5)	global: /tmp/test/GTAGS seems to be corrupted.

Version 6.5.4 - Mar 27 2016

This is a bug fix release.

[CHANGES]
Changed:
o gtags.conf: The entries which include '.xml' were commented out,
  because they require libxml.a. If you use them, please uncomment them.

[FIXED BUGS]
Serious bug:
o universal-ctags.la: Universal ctags plug-in parser did not work
  on almost files. Now it works.

	$ echo 'void a() {}' >a.inl
	$ echo 'void b() {}' >b.cpp
	$ gtags --gtagslabel=new-ctags
	$ global -x '.*'
	a                   1 a.inl            void a() {}
	(b.cpp was ignored.)

Version 6.5.3 - Mar 18 2016

[CHANGES]
New facilities:
o Added new plug-in parser 'universal-ctags.la'.
o gtags.conf:
  - Added new entry 'universal-ctags'.
  - Added new variable 'ctagscom'. You can overwrite the path of ctags(1)
    dynamically for exuberant-ctags.la, universal-ctags.la and pygments-parser.la.

Changed:
o gtags.conf: Added the following patterns to the skip list.
  '*.o,*.a,*.so,*.lo,*.zip,*.gz,*.bz2,*.xz,*.lzh,*.Z,*.tgz,*.min.js,*min.css'
o gtags: Added some explanations for the --explain option.

[FIXED BUGS]
o global: Global generated incorrect path with the --color option.
  Now, it works well.

        [bad case]
	+- GTAGS
	+- hi/
	    |- foo.cpp
	    +- what/

	$ cd hi/what
	$ global -P hi/foo.cpp --color
	foo.cpp         # It should be '../foo.cpp'.

o global: Global aborted in obstack_free() in some cases. Now it works well.
o htags: Htags ended abnormally when there is a file which includes single
  quote characters in its file name. Now, it works.

Version 6.5.2 - Dec 16 2015

[CHANGES]
New facilities:
o Improvements of gtags.conf
  - Including from another file: Label syntax is expanded. (:tc=label[@file]:)
  - Variable substitution: B shell like variable substitution is available.
  - Addition of variables: 'bindir', 'datadir', 'libdir' and 'localstatedir'.
    By default, these variables has a value given by the configure script.
  - gtags.conf(5): Online manual of the configuration file.
o global: Now the -N(--nearness) option also works with the -P and -g command
  as well as the tag search command.
o gtags.vim: New custom variable 'Gtags_Close_When_Single' (default 0).
  If this variable is set to 1, quickfix window is closed when single tag.

Changed:
o gtags-cscope: Title changed to reduce misunderstanding.
  Find locations calling this function: -> Find references of this function:

[FIXED BUGS]
o gtags.el: a strange error message in gtags-visit-rootdir was fixed.

	$ cp /dev/null main.c
	$ ls
	main.c
	$ emacs -f gtags-mode main.c
	[Emacs mini buffer]
	M-x gtags-visit-rootdir[ENTER]
	Visit root directory: /tmp/test/[ENTER]
	/tmp/test/main.c is not directory.      <= STRANGE ERROR

o gtags (C, C++): Gtags couldn't handle enums in the case that there are
  newlines between "enum" and " {". Now it can handle correctly.

	+-------------
	|typedef enum 
	|{
	|  E_FIRST = 1,
	|  E_SECOND
	|} FIRST_SECOND;
	+-------------
	$ global -x '.*'
	E_FIRST             3 test.h             E_FIRST = 1,
	FIRST_SECOND        5 test.h           } FIRST_SECOND;	<= E_SECOND not found
	$ _

	+-------------
	|enum
	|tag
	|{ ... };
	+-------------
	$ global -x '.*'
	$ _			<= tag not found

o gtags.conf: some part of a comment line (start with '#') was not skipped
  when the line is very large. Now it is skipped correctly.
o gtags: If the DLL path includes ':', loading failed. Now it works.

Version 6.5.1 - Sep 15 2015

[CHANGES]
New facilities:
o gtags(c, c++): New environment variable GTAGSFORCEENDBLOCK.
  If this variable is set, each '}' at the first column brings
  end of all blocks.
o gtags: New --skip-unreadable option.
  If this option is specified, gtags skips unreadable files
  instead of exiting the command.

[FIXED BUGS]
o gtags: There was a difference of interpretation of the langmap
  between gtags and ctags. Now there is no difference.

o gtags (C++): Gtags did not pick up 'my_type1' as a definition
  in the following example:
	[xxx.cpp]
	+------------------------
	|using my_type1 = double;
  Now it picks up the symbol as a definition.

o gtags (C++): gtags picked up 'DomainId_t' as a definition
        in the following example:
	[xxx.cc]
	+------------------------
        |typedef std::map<DomainId_t, int> map_t2;
  Now it does not pick up it as a definition.

o gtags (C, C++): Gtags did not pick up 'pr_debug' as a definition
  in the following example:
	[xxx.h]
	+------------------------
	|extern void dump_stack(void) __cold;
	|#define pr_debug() printk()
  Now it picks up it as a definition.

o gtags (PHP): Gtags did not treat back-quote correctly.
	[xxx.php]
	+------------------------
	|<?php `ls $echo ~/*`; ?>
  Now it works.

[INCOMPATIBLE CHANGES]
o gozilla: Now, gozilla invokes firefox as a generic browser, that is, using
  command line 'firefox url'. Because firefox have removed the -remote command
  since version 39.

Version 6.5 - June 10 2015

[CHANGES]
New facilities:
o global: New -N (--nearness=[start]) option.
        Nearness sort method is available for the output of tag search command.
	The result of nearness sort is concatenation of the followings ([1]-[n])
	in this order. The default of 'start' is the current directory.
        [1] Output of local search in the 'start' directory.
        [2] Output of local search in the parent directory except for [1].
        [3] Output of local search in the grandparent directory except for [1]-[2].
        (repeat until the project root directory)
        [n] Output of local search in the project root directory except for [1]-[n-1].
        In each directory, they are sorted by alphabetical order.
o global: Now the --literal option also works with the tag search command,
        -P command and -I command as well as the -g command.

[FIXED BUGS]
o htags: The -c and -x option of htags(1) were still available in the help
  message, even though they had actually been removed. Now, these options
  are removed completely.
o gtags (PHP): Against the following source code, gtags(1) aborted with a message
  'short of memory'. Now it works.
        [nullstring.php]
        +----------------
        |<?php
        |define('');
        |?>
        +----------------

        $ gtags
        gtags: failed to parse template [+1 ./a.hh].
o gtags (C, C++): Gtags(1) couldn't pick up 'E2' as a definition. Now it works.
        [test.c]
        +----------------

Version 6.4 - March 24 2015

[CHANGES]
New facilities:
o gtags: Now --sqlite3 option is supported formally. This option uses
  SQLite3 API instead of BSD/DB API for making tag files.
  To use this option, you need to invoke configure script with
  --with-sqlite3 in the build phase.

        [configuration phase]
        $ ./configure --with-sqlite3    # use sqlite3 API

        [execution phase]
        $ gtags --sqlite3               # make sqlite3 tag files

o gtags: --single-update option supports deletion of a file.
  Now the next command line works well.

	$ rm test.c
	$ gtags --single-update=test.c

o gtags: New --explain option. This option explains handling files.
  You can know the following information:
  - Skipped reason for each skipped files.
  - Used parser and its library path for each source file.

[FIXED BUGS]
o global: global(1) could not pick up source code from source files
  in library projects (GTAGSLLIBPATH) if their tag files are compact
  format. Now it works.

[INCOMPATIBLE CHANGES]
The following features of htags(1) were removed.
o The -c (--compact) option.
o The --system-cgi option.
o The --overwrite-key option.
o The -x (--xhtml[=version]) option.
  All files are 1.0.
o The following configuration variables:
  colorize-warned-line (substitute: --colorize-warned-line)
  gzipped_suffix (substitute: not available)
  htags_options (substitute: HTAGS_OPTIONS)
  ncol (substitute: -n, --line-number [n])
  normal_suffix (always '.html')
  no_order_list (substitute: --no-order-list)
  script_alias (substitute: not available)
  tabs (substitute: --tabs n)
  xhtml_version (always 1.0)

Version 6.3.4 - February 2 2015

  a lower alphabetic character ()" in some condition. Now it is fixed.
o gozilla/Makefile.am: Installation made a directory outside of the DESTDIR.
  Now it is fixed.

	$ gozilla -d main	# shows definitions of main()

o vim74-gtags-cscope.patch: New patch for vim + gtags-cscope to treat
  file names which include spaces correctly. Please see README.PATCHES.

Release for beta test:
o Added --sqlite3 option which uses SQLite3 API instead of BSD/DB API for
  making tag files.

o gtags-cscope.vim: There was a calling to undefined function.
  Now it works.

Version 6.3.2 - September 4 2014

[CHANGES]
New facilities:
o Pygments plug-in parser by Yoshitaro MAKISE.
  By this parser, you can apply gtags(1) to wide variety of programming
  languages supported by Pygments. The method of plug-in is very simple.
  See 'plugin-factory/PLUGIN_HOWTO.pygments' for details.
  It should mention especially that Pygments plug-in parser can treat both 
  definitions and references using Exuberant Ctags together.

              v
    $ geco main [ENTER]
    QUERY> init         # narrowing down
    (less's screen)

    The same options are available on the both prompts:
    $ geco <options> arg
    :tag <options> arg

[INCOMPATIBLE CHANGES]

  Instead, idutils 4.5 or later is required.

[FIXED BUGS]
o global: With combination of the --invert-match and --literal, it did not match
  the last line of files. Now it works.
o global: Literal search with the -i option printed an unmatched tag in a certain
  kind of case. Now it works.

  completely. So, ./configure failed when there is no curses library.
  Now it avoids building gtags-cscope completely.
o htags: Imported a patch to fix htags on Windows Vista+ (tmpfile wants to create
  its file in the root directory, which is not writable by normal users).

  datadir(/usr/local/share) to localstatedir(/usr/local/var) because
  datadir should be used for read-only data.
  By default, you must execute "cd HTML; sh bless.sh" as a root user,
  since the site key directory can not be written except for root user.

Version 5.9.1 - July 19 2010

[CHANGES]
New facilities:
o gtags: New gtags.files file.

  If a file called 'gtags.files' exists in the current directory,

  $ gtags -i -f files
  
  $ cp files gtags.files
  $ gtags
  $ gtags -i

The latter has an advantage that 'global -u' can use the mechanism too.

o htags: New --auto-completion option.
  Enables completion input method for the search form (requires http server).
o htags: New --tree-view option.
  Use tree view for the file index.
o htags: New --suggest2 option
  --suggest - use popular options without frame, CGI and javascript.
  --suggest2 - use frame, CGI and javascript in addition to the --suggest.

The --auto-completion and --tree-view option requires javascript language
in your browser.  If your browser is one of the followings, it will work.

        * GNOME web browser
        * firefox
        * chrome

o global: Allows -I option for the -c command.

[FIXED BUGS]
o gtags.el: The following commands fail with a message 'Beginning of buffer'
  when the cursor is at the head of the buffer.
        gtags-find-tag, gtags-find-rtag, gtags-find-symbol,
        gtags-find-tag-from-here, gtags-find-with-idutils, gtags-find-with-grep

[INCOMPATIBLE CHANGES]
o Safe-CGI mechanism was modified.
  The parameter of the -S option was changed.

Version 5.9 - June 8 2010

			*** Caution ***

This version of Global doesn't support tag files of the former version.
If you install this version, you should remake all tag files again using
gtags(1) in this package. Though new gtags's speed has improved very much,
you need not hurry up to upgrade it if you have a lot of tag files of
former version. Thank you for your cooperation.

[CHANGES]
New facilities:
o global: New --encode-path option.
  This option is to support path names which includes blanks.
o globash: New command.
o global: Accept the -r and -s option at the same time.
o gtags, global, htags: Allows path name which includes blanks.
  This is experimental operation. You can use this function by setting
  environment variable 'GTAGSALLOWBLANK'. Please try and send us bug reports.
o gtags: Speed-up using 'sorted writing'.
  It uses external POSIX sort program (/usr/bin/sort). If your system's path
  is different from /usr/bin/sort, you will see the following message:

    Warning: POSIX sort program not found. If available, the program will be speed up.

  In that case, please rebuild Global with the --with-posix-sort option.

    $ ./configure --with-posix-sort=<path of POXIS sort program in your system>

[FIXED BUGS]
o gtags-cscope: When using gtags-cscope with the -C argument to ignore case,
  it passes malformed arguments to global which prevents it from looking
  up the definition points of the requested identifier.
o global: The -I command with the --result option fails.

[INCOMPATIBLE CHANGES]
o Global shifted to new architecture and new tag files. Global doesn't use
  GSYMS tag file any longer. New Global doesn't support older tag files.
  When you use older tag files, you will see the following message:

	global: /*/GTAGS seems older format. Please remake tag files.

o Removed undermentioned config variables:

Removed config variable         replacement
-------------------------------------------------------------------------
definition_header(position)     -h, --func-header[=position]
disable_grep                    --disable-grep

-------------------------------------------------------------------------
  *1 Please note that '--disable-idutils' is opposite to 'enable_idutils'.

If you use above removed variables in your configuration file, please
use config variable 'htags_options' instead.

For example:
:definition_header=before:full_path:other_files:table_flist:flist_fields#3:disable_grep:\
        |
        v
:htags_options=--func-header=before --full-path --other --table-flist=3 --disable-grep:\

Version 5.8.2 - April 1 2010

[CHANGES]
o gtags, htags: Changed the algorithm for detecting binary file.
  If the first 512 bytes contain any character of 0-7, 14-26,28-31,
  the file is basically considered to be a binary. New method can correctly
  treat multi-byte text file too. This is suggested by Erik Jonsson.
o global: Changed the -i option to be effective with the -c command.

[INCOMPATIBLE CHANGES]
o gtags: the built-in parser in function layer has become the default.
  Config parameter 'use_builtin_parser' is not used any longer.
o htags: Changed the default output from HTML to XHTML.
  In older htags,
        no option: HTML
        --xhtml: XHTML
  In new htags,
        no option: XHTML
        --xhtml: XHTML
        --html(new option): HTML

Version 5.8.1 - March 6 2010

[CHANGES]
New facilities:
o gtags: Added support of function layer plug-in parser by Hideki IWAMOTO.
  This includes exuberant-ctags shared library, an example of plug-in
  parser using Exuberant ctags. To use this, please try the following:
  (It assumed that Exuberant ctags exists in "/usr/local/bin".)
        $ ./configure --with-exuberant-ctags=/usr/local/bin/ctags
        $ make
        $ sudo make install
        $ gtags --gtagsconf=/usr/local/share/gtags/gtags.conf --gtagslabel=plugin-example
  Please see plugin-example/README for the detail.
o htags: Added call-tree facility using cflow(1).
  Please try this:
        $ gtags
        $ cflow --tree --format=posix `global -P` >cflow.out
        $ htags --cflow=cflow.out
  Input file must be POSIX format(use the --format=posix).
  GNU cflow is available at: http://www.gnu.org/software/cflow/

[FIXED BUGS]
gtags-parser: Input of long token(>= 512bytes) brings buffer overflow.

[INCOMPATIBLE CHANGES]
gtags: Gtags using function layer plug-in parser always makes all tag files
even if some of them are empty. Old style command layer plug-in parser makes
only specified tag files. The new specification is better than old one for the
reason that tag files of different parsers don't mix.
If you want to know whether a tag file is empty or not, please use the following
commands:
        $ global '.*' -r                # GRTAGS is empty?
        $ global '.*' -s                # GSYMS is empty?

Version 5.8 - February 5 2010

[CHANGES]
New facilities:
o gtags: Built-in parser by Hideki IWAMOTO.
  This improvement has shortened the processing time to about 1/3.
  Built-in parser is not effective by default in this version.
  To use built-in parser, please define 'use_builtin_parser' in your
  configuration file like follows:

	$ cp /usr/local/share/gtags/gtags.conf $HOME/.globalrc
	$ vi $HOME/.globalrc
	+------------------------------------
	|...
	|default:\
	|       :tc=gtags:tc=htags:use_builtin_parser:	<= ADD THIS

  In the near future, built-in parser will become effective by default.
o gtags.el: Single 'GTAGS SELECT MODE' buffer of gtags.el by Yushi Oka.
  If "gtags-select-buffer-single" is non-nil, then 'GTAGS SELECT MODE'
  buffer is kept single.
o gtags-cscope.vim: Plug-in script which integrates Global and vim editor
  using cscope interface. Since this script makes vim think Global is cscope,
  you can use the tag stack facility of vim like cscope. Gtags-cscope can
  coexist with gtags.vim.

[FIXED BUGS]
o gtags.el: the completion read in the gtags-find-file fails into endless
  loop when the input string is NULL.

[INCOMPATIBLE CHANGES]
o gtags(built-in parser): In the existing parser (gtags-parser), some symbols
  were stored in both GRTAGS and GSYMS. In the built-in parser, all the symbols
  defined in GTAGS have been moved from GSYMS to GRTAGS. New specification
  is more consistent, and useful for efficiency improvement. If you feel this
  a problem, please inform bug mailing list of your insistence.

Version 5.7.7 - December 19 2009

[CHANGES]
o htags: More accurate statistics mechanism using gettimeofday(2) and getrusage(2).
o gtags: New --statistics option.
o gtags.el: Added completion support for the 'gtags-find-file'.
o global: Allows tag files in the system's root directory.
  This does not recommend tag files to be put on the system's root directory.
  In some systems except UNIX, putting tag files there might be suitable.
[FIXED BUGS]
o The --from-here option didn't work with compact format GTAGS (gtags -c).

Version 5.7.6 - October 6 2009

[CHANGES]
New options:
o gtags: --single-update=file
  Update tag files for single file. It is considered that the file was updated,
  and other files were not updated. This option implies the -i option.
  If the file is new then --single-update is ignored, and the processing is
  automatically switched to the normal incremental updating.
o gtags: --dump=tag-files
  Dump a tag file. Output format is 'key<tab>data'.

Version 5.7.5 - March 14 2009

[CHANGES]
Change of gtags:
o Revived the -c option.
  If this option is specified, gtags uses compact format for GTAGS.
  This option does not influence GRTAGS and GSYMS, because they are always
  made using compact format.
  If you think that GTAGS is too big, please use this option.
o Removed the limitation of the depth of the directory hierarchy. 
o Changed not to do useless inspection for the files in the directories
  which are listed in the skip list.

Version 5.7.4 - January 5 2009

[CHANGES]
o global: In compact format, operation to non-existent lines was changed
	to avoid needless abnormal termination.

	-- Delete lines 20-last from the test.c.
	$ global -xr func

	(OLD)
	func      10 test.c           func(a);
	global: unexpected end of file. './test.c: 19/20'
	$ echo $?
	1                                       <- abnormal termination

	(NEW)
	func      10 test.c           func(a);
	func      20 test.c                     <- plain space means non-existence
	$ echo $?
	0                                       <- normal termination

[FIXED BUGS]
o gtags-parser: Gtags-parser had overlooked objects in 'extern "C" {...}'(C, C++).
  Now, it can pick up them.
o gtags-parser: Gtags-parser was not able to recognize the following definitions.
  Now, it can pick up them.

        int invisible /* COMMENT */ ()
        {
        }

        int also_invisible // COMMENT
        ()
        {
        }

        int visible () // COMMENT
        {
        }
o gtags-parser: Gtags-parser had overlooked 'Foo' in the following construct.
  Now, it can pick up them.

        namespace
        Foo
        { ...

  However, this works:

        namespace Foo
        { ...

Version 5.7.3 - October 29 2008

[FIXED BUGS]
gtags: Gtags with the -f option caused segmentation fault if a file in the
file list is not in the working directory or its sub-directories.
gtags.pl: Version test was failed.

Version 5.7.2 - September 30 2008

[CHANGES]
New functions:
o gtags: New -O(--objdir) option.
o gtags.el: New commands: gtags-select-tag-other-window and gtags-find-tag-other-window.
o htags: Picks up the words 'include', 'required' and 'required_once' statement in PHP
  source files. Htags makes a link to the file described in above statements if it is
  accessible from the current directory.

[INCOMPATIBLE CHANGES]
o gtags: Changed to skip all files whose first character of name is '.'.
  The following paths were deleted from the DEFAULTSKIP list in configure.ac,
  since new rule covers them.

        .notfunction
        .gdbinit
        .cvsrc
        .cvsignore
        .gitignore
        .cvspass
        .cvswrappers
        .deps/
        .snprj/
        .svn/
        .git/

o gtags.el: Changed so that the visited files are left after invoking
  the 'gtags-pop-stack' command. If you hope old specification,
  please set gtags-pop-delete to true like follows:

        [$HOME/.emacs]
        (setq gtags-mode-hook
          '(lambda ()
                (setq gtags-pop-delete t)))

Version 5.7.1 - April 21 2008

[CHANGES]
New functions:
o gtags-parser: Picks up symbols in #{if,elif,ifdef,ifndef} line in assembly source.

Other changes:
o gtags.conf: Added new skip files: cscope.po.out,cscope.in.out
o gtags.vim: Added error check for the -f option.

[FIXED BUGS]
o Fixed imperfect symbolic link support.
  - global: Global didn't work with the -f option.
  - gozilla: Gozilla couldn't convert paths which include symbolic link.

Version 5.7 - March 25 2008

[CHANGES]
New functions:
o gtags: Allows symbolic links which point to a directory.
  In older version, such symbolic links were ignored with warning messages.

	[Example]

	/tmp
	  +-global
	  |  +-GTAGS
	  |  +-gtags ----+ (symbolic link to ../work/gtag2)
	  |  +-htags --+ | (symbolic link to ../work/htag2)
	  |            | |
	  +-work       | |
	     +-gtag2 <-+ |
	     |  +-gtags.c|
	     |           |
	     +-htag2 <---+
		+-htags.c

	Old version
	===========
	$ cd /tmp/global
	$ gtags
	Warning: './gtags' is a directory. (Ignored)
	Warning: './htags' is a directory. (Ignored)
	...
	$ global -f gtags/gtags.c
	'/tmp/work/gtags/gtags.c' is out of source tree.

	New version
	===========
	$ cd /tmp/global
	$ gtags
	$ global -f gtags/gtags.c
	usage              91 gtags/gtags.c  usage(void)
	help               98 gtags/gtags.c  help(void)
	...
	$ global -f gtags/../htags/htags.c
	mkdir              61 htags/htags.c  #define mkdir(path,mode) mkdir(path)
	link               62 htags/htags.c  #define link(one,two) (-1)
	...
	% cd gtags                                      <= get out of the source tree
	$ global -f gtags.c
	global: GTAGS not found.
	$ pwd
	/tmp/work/gtags

	Though the symbolic link to a directory might confuse users,
	it is originally as such. They should understand the characteristic.

o gtags-parser: Picks up the names of struct, union, enum and enum member
  as definitions.
o gtags.el, gtags.vim, gtags.pl: More accurate, language independent context jump
  using new --from-here option of global(1).
o gtags.el: Customizable path style in the [GTAGS SELECT MODE].
  You can select one of the followings:
	root		relative from the root of the project (Default)
	relative	relative from the current directory
	absolute	absolute (=relative from the system root directory)

New options and variables:
o global: New --from-here option. This option is used by context jump facility. 
o gtags,htags,gtags-parser: New environment variable GTAGSFORCECPP.
  If this variable is set, each file whose suffix is 'h' is treated as
  a C++ source file.
o gtags.el: Added new variable for customizing the path style in the
  [GTAGS SELECT MODE].

Other changes:
o global.texi: Added descriptions about gtags-cscope (fake cscope).

[INCOMPATIBLE CHANGES]
o gtags.el: Changed the default path style in [GTAGS SELECT MODE] relative
  from the root of the current project. In older version, it was absolute
  by default.
o nvi-1.79-gtags.diff: The support for nvi-1.79 ended. This nvi is an very
  old program, and is not distributed any longer.
o gtags-parser: Removed the -d(--define) and -t(--typedef) option, because they
  have already been the default operation.

[FIXED BUGS]
o gtags: Failed to process new GCC source code.
o gtags.vim: Completion facility didn't work with the -f option of Gtags.
o htags: Self-referred links.

Version 5.6.2 - October 26 2007

[CHANGES]
* gtags-parser: In C++ source code, now ignores forward definitions of classes
  (e.g. "class name;")

Version 5.6.1 - August 11 2007

[CHANGES]
* gtags.conf: Added '.git/' to the DEFAULTSKIP list.

[FIXED BUGS]
* global: Global(1) with the -t option didn't print correct line number.
  Gtags.vim also didn't work correctly due to this bug. This bug was
  introduced in Global-5.4.

Version 5.6 - July 6 2007

[INCOMPATIBLE CHANGES]
* All commands: According to the GNU coding standard, the --version option
  shows always verbose message without --verbose option.

[CHANGES]
* Migrated to GNU GPLv3 and GNU LGPLv3.
* gtags-parser: Added support for assembler directive ".macro" and ".equ".

[FIXED BUGS]
* global(1): Fixed a memory leak.

Version 5.5 - May 5 2007

* GNU Global became a BOKINware.

* gtags-parser: Added support for 'enum' (java).
* gtags.el: Changed to work without event-point function.

Version 5.4.1 - March 10 2007

[CHANGES]
* htags: New --item-order option.
  Specify the order of items in the top page. The spec is a string
  which consists of item signs in order. Each sign means as follows:
  c: caution, s: search form, m: mains, d: definition, f: files.
  The default is 'csmdf'.

[FIXED BUGS]
* htags: didn't extract some '#include' correctly.

Version 5.4 - January 29 2007

[INCOMPATIBLE CHANGES]
* Further compression of tag files (format version 5).
  Though new global can read older tag file since version-5.0, older
  global cannot read new format. It might say like follows:
	"GTAGS seems new format. Please install the latest Global."

[OTHER CHANGES]
* global: Improved performance when the -x option is not specified.
* globash.rc: New option -l for tag search command (x,r,s,g,P,I,f).
  This option invokes less(1) directly without using tag stack.
* Verbose messages are unified.
  P option      file not found
		<n> files located
  others        object not found
		path format: <n> files located
		other format:<n> objects located

[FIXED BUGS]
* Gtags(1) and global(1) didn't work well in the system root directory('/').

Version 5.3 - November 20 2006

[INCOMPATIBLE CHANGES]
* global: Changed not to locate other symbols (-s) in GTAGSLIBPATH.
  This is the original specification of Global.
* global: Discontinued sorting when the -I(--idutils) option specified.
  The output of gid(idutils) is sorted by the suitable way. Though the order is
  slightly differ from global(1), it need not be sorted again.

[OTHER CHANGES]
* global:  New -O(--only-other) option.
* htags: Added some new options and new arguments which are synonyms of
  configuration variable. This decreases dependence on configuration file.

  new option              | configuration variable
  ------------------------+-------------------------
  --disable-grep          | disable_grep
  --table-list            | table_list
  --tabs=<n>              | tabs
  --full-path             | full_path

  new argument            | configuration variable
  ------------------------+-------------------------
  --line-number [columns] | ncol
  --func-header [position]| definition_header
  --xhtml [version]       | xhtml_version

	(*=default)
	position: before, right, *after
	version: *1.0, 1.1

* htags: Changed to use each 'CVS/Repository' file to generate URLs if it is available.
* htags: Added '.gitignore' to the DEFAULTSKIP list.

* gtags.el:
  - Shorten path names in [GTAGS SELECT MODE]:
    If the project directory is specified using 'gtags-visit-rootdir', gtags.el print path
    using the relative path name from the project directory, else print absolute path name.
  - Support dynamic completing-read of tag name.
    gtags-make-complete-list is deprecated. You can enjoy tag name completion without
    invoking this command.

[FIXED BUGS]
* gtags: gtags had exited when it encountered dead symbolic link.

Version 5.2 - August 8 2006

* htags: Added new options:
  - -h(--func-header) option.
  - -I(--icon) option.
  - -T(table-flist[=fields]) option.
  Suggested options:
	$ htags -vsanohIT
* htags: Changed the default color of braces from blue to red to make them stand out.
* htags: Always enable 'Grep pattern' form when the -f(--form) option specified.
  Removed configuration variable 'enable_grep' since it became meaningless. Instead, added
  a new variable 'disable_grep'.
* htags: Added more profitable tips in the file browser.
  - File        size of bytes
  - Directory   number of files in the directory.

Version 5.1 - June 10 2006

[INCOMPATIBLE CHANGES]
* Changed the priority about the --result option to make the format
  specification easy. The --result option is now given to priority
  more than the -t and -x option. (This option appeared in version 5.0.)

[OTHER CHANGES]
* New program 'gtags-cscope'.
  Gtags-cscope is a pseudo cscope which implements the line-oriented
  interface. You can use this command for various clients instead of
  true cscope.
* Added new format 'cscope' to the argument of --result=<format>.

Version 5.0 - April 21 2006

[INCOMPATIBLE CHANGES]
* Moved to new tag format. (GTAGS, GRTAGS, GSYMS, GPATH)
  The purpose is as follows:
  o Allows path name including blanks, at least in tag files.
    (Global still doesn't support the path name which contains blanks.)
  o Decrease disk space used.
  o Make tag format simpler.
  o Realize stable performance.

  Hereafter, older tag format is not supported.
  Compact format was progressively canceled with the adoption of
  the new tag format. The -c(--compact) option of gtags(1) was removed.

  The following error messages are displayed in wrong combinations:
  - older global and new tag file
    $ global -x main
    GTAGS seems new format. Please install the latest Global.
  - new global and older tag file
    $ global -x main
    GTAGS seems older format. Please remake tag files.

  Known problem:
  - older global and new tag file
    Global(1) with the -g or -P command will always work as if invoked
    with the -o option. There is no way to avoid this problem.

New requirement:
* Added new requirement of plug-in parser
  Plug-in parser must process the arguments in the order they are given
  in the command line. In each file, any order is acceptable.
  Exuberant Ctags with the -xu option meets this requirement.
  (See global.info for the detail.)

Removed options:
* gtags(1): Removed the -c(--compact) option.
  Compact format was progressively canceled with the adoption of new
  tag format.
* gtags(1): Removed the -o(--omit-gsyms) option.
  This option was necessary in the past to use the program in a incompetent
  machine with a small hard disk. Since most recent machines has powerful
  CPU and mass hard disk. This options might already be unnecessary.
* htags(1): Removed the --style-sheet option.
  This was a really halfway option, and now nobody might need it because
  the --xhtml option became available.

[OTHER CHANGES]
New options:
* global: New --result=<format> option. Grep format became available.

  <format>: path,ctags,ctags-x,grep
        
  conventional option | newly added option
  --------------------+---------------------
  (none)              | --result=path
  -t                  | --result=ctags
  -x                  | --result=ctags-x
                      | --result=grep
        
  The -t and -x option are given to priority more than the --result
  option.

Version 4.8.7 - September 30 2005

New options:
* gtags: New --file <file list> option.
  Using this option, you can give the file set which should be
  processed to gtags.

        % find . -type f -print >/tmp/list
        % gtags --file=/tmp/list
        or
        % find . -type f -print | gtags --file=-

* gtags: New --max-args option.

Improvement of efficiency:
* Gtags was improved of performance by changing algorithm of the
  incremental updating. Along with it, the verbose message was
  greatly changed.
* Gtags was improved of performance by decreasing the frequency
  of the parser invoking. Under the influence of it, the verbose
  message is not necessarily real-time. If you dislike this behavior,
  use the --max-args option of gtags. You can control the frequency
  of the invoking with the option. With --max-args=1, the program
  does the same behavior as older version.
* Htags was improved of performance by decreasing the frequency
  of the parser invoking.
* Htags was improved of performance by omitting flushing temporary
  files to the disk.

Fixed bugs:
* Htags didn't treat here document (<<<word) of PHP source code correctly.
  Now it is treated correctly.
* Htags didn't treat HTML part of PHP source code correctly.
  Now it is treated correctly.

Other facilities:
* Added 'Htags Hyper-text Reference Kit'.
  The hypertext generated by htags(1) is now available from external
  programs. This kit helps you to convert the path of the source
  file into the URL in the hypertext.

* doc/global.txi: Added the usage of Doxygen using Global.

Version 4.8.6 - May 12 2005

[INCOMPATIBLE CHANGES]
* htags: Changed the value of id attribute and name attribute of
  the anchor of each line like follows:
	<a id='100' name='100'> => <a id='L100' name='L100'>
  It is because XHTML prohibits the id attribute which starts
  with a digit. If you refer these anchors from outer system,
  please rewrite them.

[OTHER CHANGES]
* htags: New option --insert-header and --insert-footer.

Version 4.8.5 - April 19 2005

* htags: Added the support for XHTML (--xhtml).
  If the --frame option is specified then generates XHTML-1.0 Frameset,
  else if configuration variable 'xhtml_version' is set to 1.1 then generates
  XHTML-1.1 else XHTML 1.0 Transitional.
  You can customize the appearance using style sheet file 'style.css'.
* htags: Added configuration variable 'xhtml_version'.
* htags: Added 'html/' to the fault skip list.
  It is the output directory of doxygen document.
* gtags-parser: Added yacc directives introduced in bison-2.0.
  %default-prec(%default_prec)
  %expect-rr(%expect_rr)
  %initial-action
  %no-default-prec(%no_default_prec,%no_default-prec,%no-default_prec)
  %nondeterministic-parser

Version 4.8.4 - March 4 2005

Fixed bugs:
* gtags-parser: C and C++ parser was broken.
* gnusort: Couldn't be compiled in Solaris environment.

Version 4.8.3 - February 26 2005

[INCOMPATIBLE CHANGES]
* The support for DOS and Windows 32 ended.
  But it doesn't mean the deletion of the code for DOS and Windows 32.
  We leave the support to outside projects and accept their code as is.
  Therefore, anything has not been changed substantially up to now.
* Renamed gctags(1) to gtags-parser(1) because some systems have
  another 'gctags' which does not relate to Global.
* Changed gtags-parser(1) to decide language type of the source files
  only by the suffix. In older version, *.h files were considered to be
  C++ source files if they include token 'class'. New version considers
  *.h files always to be C source files. If you want gtags-parser to
  consider them C++ then you must redefine new configuration variable
  'langmap'.
  
[OTHER CHANGES]
Fixed bugs:
* htags: The --gtagsconf and --gtagslabel option didn't work correctly.
* htags: Buffer overflow occurred in dupindex.c:makedupindex().
* htags: Could not ignore path name which includes blank correctly.
New features:
* gtags,htags: New configuration variable 'langmap'.
  This variable is used for customizing the mapping of languages and the
  parsers, and it includes the function of obsoleted 'suffixes' variable.
  If you use 'suffixes' then it is effective else Global internally
  generates the value of 'suffixes' from the 'langmap'.
  The reason to continue 'suffixes' is that it is needed for plug-in parser.
  If you don't use plug-in parser then you should use 'langmap' instead.
* htags: New configuration variable 'copy_files'.
  With the -f option, htags makes links of tag files in the 'cgi-bin'
  directory by default. With this variable, htags copy them instead of
  linking.

Version 4.8.2 - November 11 2004

[INCOMPATIBLE CHANGES]
* The support for postgres ended.
* Removed htags.pl (older version of htags written by Perl) completely.
* Removed configuration variables: sed_command and sort_command.
  Sed(1) and sort(1) are not necessary any longer.

[OTHER CHANGES]
Fixed bugs:
* Fixed wrong output of 'global -Po'.

New features:
* gctags(assembly language):
  - In addition to `call', `jsr' is recognized as call instruction.
    Although various call instructions exist like `bl' or `calls',
    only `call' and `jsr' are used widely.
  - Macros like ENTRY or EXT are taken up as reference,
    when definitions exist in somewhere else.
  - Warning is displayed when a comment is not closed.
  - C_SYMBOL_NAME and C_ENTRY are recognized as a macro
    which shows the start of a function.
  - The string which is not closed finishes at the end of line.
    This behavior is the same as GNU C pre-processor.
  - The check of correspondence of "#if" and "#endif" was deleted.
    This did not exist in version 4.8.
* Added '.snprj/' directory to the DEFAULTSKIP list.
  This is the tag directory for the Source-Navigator.

Version 4.8.1 - October 6 2004

Fixed bugs:
* htags: The -d option of htags didn't work. Now it works well.
* htags: Didn't recognize continued line and null directive(#).
  Now it works well.

New features:
* htags: Configurable suffix list for include file.
  (See man htags(1). configuration variables: include_file_suffixes)
* htags: Uses environment variable TMP if TMPDIR doesn't exist.(only DJGPP)
* htags: Warns about unknown pre-processing directive. As the exception,
  when unknown preprocessing directive appears in assembly source,
  it will be recognized as the start of a shell comment.  
* htags: Added all yacc directives supported by bison-1.875.

Version 4.8 - August 26 2004

* Htags(1) was rewritten in C language completely. It is compatible
  with the perl version and the performance has been improved greatly.
  The perl version is left in the package for the time being as
  '/usr/local/bin/htags.pl' by default.
* htags: In PHP source code, now picks up variables in strings ("${aaa}").
* gctags: Added __thread to the reserved word list of C and C++.

Version 4.7.2 - June 7 2004

Fixed bugs:
* Fixed obsolete style option for sort(1).

Version 4.7.1 - June 1 2004

New features:
* Added support for home_etc(3) facility on PLD Linux/GNU.
* gctags: Now picks up external defined functions as symbols.

Fixed bugs:
* Global(1) didn't work with the GNU sort(1) based on POSIX 1003.1-2001.
  GNU sort(1) with the latest glibc doesn't accept obsolete +POS1[-POS2]
  style option. Now global(1) works well with it.
* Global-4.3 and the later couldn't treat shadow tree. Now it works well.

Version 4.7 - Feb 1 2004

* gtags.vim: Plug-in script which integrates Global and vim editor.
* global.txi: Added the usage of gtags.vim script.
* global: The -o option is now available with the -P command.
* gctags: Fixed a bug: Gctags couldn't recognize the definitions
  in namespace block. Now it can recognize them.
* Changed to install gtags.conf and other files to $datadir/gtags.
* Borland C++ compiler support in Windows32 ended because
  - Now, Cygwin environment is widely used.
  - Borland C++ compiler is not free software.

  The w32/ directory is left in this release but will be removed in the
  future release.

Version 4.6.1 - Oct 3 2003

* gtags, htags, gctags: Added '.hpp' to the suffix list of C++ source file.

Version 4.6 - July 2 2003

[INCOMPATIBLE CHANGES]
* Changed the default value of configuration variable 'definition_header' to 'no',
  because definition header is unsightly according to the place, especially
  in class definition.

[OTHER CHANGES]
* Added support for PHP language.
  (Known problems in htags)
  - Variables in string cannot be recognized.(global can recognize that.)
  - In HTML, character strings which are same spelling with the reserved
    word of PHP are recognized as reserved words of PHP.
  Htags(1) should be rewritten greatly to solve above problems in the future.
* Added support for SCM_DEFINE macro which is part of guile-snarf.
* Added 'right' as a value of configuration variable 'definition_header'.
* Added some tool tips.
  - Alphabet in the alphabetical definition index shows the count of definitions.
  - File name in the file index shows the full path name.
  - Anchor in the duplicate index shows the number of duplicated objects.
* Added .cvsrc,.cvsignore,.cvspass,.cvswrappers,autom4te.cache/
  to the DEFAULTSKIP list.

Always thanks to Hideki Iwamoto san for his contribution.

[INCOMPATIBLE CHANGES]

* htags: Tool tip is now implemented by title attribute instead of javascript.
* htags: Removed the --no-javascript option because it is already unnecessary.
* global: Argument pattern is now always interpreted as an extended regular expression.
  In older version, it was interpreted as a basic or extended regular expression.
  It depended on the build environment. In the new version, if you want pattern
  to be interpreted as a basic regular expression, please specify the -G option.

[OTHER CHANGES]

New features:

htags:
* Added CVS REPOSITORY link (the --cvsweb and --cvsweb-cvsroot option).
* Added tooltips in some anchors.

  With this option, htags prints statistics information to standard error.

global:
* New -e(--regexp) option like grep(1).
* New -G(--basic-regexp) option like egrep(1).

Performance tuning:

htags:
* Reduced the size of cache file by removing unnecessary information.

  the source code.

Other modifications:

* Shut a security hole.
* Added '{arch}' and '.notfunction' to the DEFAULTSKIP list.
