+2007-05-18 Francesco Potortì <pot@gnu.org>
+
+ * etags.c: Extern definitions of some more pointer functions for
+ standalone compilation, especially important for 64bit platforms.
+ (main, print_help): --members is now the default for etags.
+ (C_entries): Parse start of C comment as a space == end of token.
+ This is not necessary for C++ comment, already parsed as newline.
+
+2007-02-05 Francesco Potortì <pot@gnu.org>
+
+ * etags.c (default_C_help, Cplusplus_help, PHP_help, print_help)
+ (main): Now --members is the default for etags, not for ctags yet.
+
+2007-01-02 Francesco Potortì <pot@gnu.org>
+
+ * etags.c (longopts): New undocumented option --no-duplicates.

+
+2006-12-28 Francesco Potortì <pot@gnu.org>
+
+ * etags.c (readline): When creating a relative file name from a
+ #line directive, leave the file name alone. The previous
+ behaviour was to make it relative to the tags file directory,
+ under the hypothesis that the #line directive file name was
+ relative to the directory of the tagged file. That hypothesis is
+ wrong with Cpp and Lex.
+
+2006-12-20 Francesco Potortì <pot@gnu.org>
+
+ * etags.c (C_entries): DEFUN names were longer by one: corrected.
+ (Makefile_targets): Do not include spaces in tag names.

+2006-08-12 Kevin Ryde <user42@zip.com.au>
+
+ * etags.c (readline): Check for double quote after #line.

+
+2006-08-12 Francesco Potortì <pot@gnu.org>
+
+ * etags.c (readline): lno is unsigned.
+ (TeX_commands): Use p++ (rather than *p++) to increment p.
+ (Lua_functions): Explicitely discard LOOKING_AT's return value.
+
+2006-08-07 Masatake YAMATO <jet@gyve.org>
+
+ * etags.c (TEX_mode): Check getc retruns EOF.
+ File ended without newline causes infinite loop.
+
+2002-07-14 Adrian Aichner <adrian@xemacs.org> (tiny change)
+
+ * etags.c: It's XEmacs, not Xemacs: change all the occurences.

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

+ the second argument is indeed a literal string.
+ (main): In append mode, sort the tags file after writing it.
+
+2005-09-27 Emanuele Giaquinta <emanuele.giaquinta@gmail.com> (tiny change)
+
+ * etags.c (longopts, print_help, main): The -a (--append) option
+ can be used in ctags also; for one, the Linux make file uses it.
+
+2004-09-13 Francesco Potortì <pot@gnu.org>
+
+ * etags.c (main): When relative file names are given as argument,
+ make them relative to the current working dir, rather than
+ relative to the output tags file, if the latter is in /dev.
+
+2004-09-13 David A. Capello <dacap@users.sourceforge.net> (tiny change)
+
+ * etags.c: (Lua_suffixes, Lua_help, lang_names, Lua_functions):
+ Support the Lua scripting language <http://www.lua.org>.
+
+2004-09-13 Francesco Potortì <pot@gnu.org>
+
+ * etags.c [EXIT_SUCCESS, EXIT_FAILURE]: Define them when no
+ <stdlib.h> is available.
+ (enum sym_type): New st_C_attribute value for parsing
+ gcc's __attribute__. Deleted st_C_typespec value.

+
+2004-09-08 Francesco Potortì <pot@gnu.org>
+
+ * etags.c: Add arch taglines
+ [LONG_OPTIONS]: make it TRUE (ifdef) or FALSE for ease of use.
+ [GOOD, BAD]: renamed to EXIT_SUCCESS, EXIT_FAILURE.
+ (suggest_asking_for_help): Fix having macros in a printf statement.
+ (consider_token): check C++ `operator' only when the token len is
+ long enough.
+
+2003-01-09 Francesco Potortì <pot@gnu.org>

+ (print_help): Now takes an argument and possibly prints lang help.
+ (print_help): Some help strings corrected. Documents
+ language-specific help.
+ (main): Only print help after having parsed all the arguments.
+
+2002-09-03 Francesco Potorti` <pot@gnu.org>

+ string that cannot be freed.
+
+2002-08-30 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (consider_token, C_entries): Switch to C++ parsing when
+ auto-detection is enabled and the `::' qualifier is met.
+ (consider_token, C_entries): Several bugs corrected that tagged
+ some declarations even though --declarations was not used.
+ (plainc): New macro.
+ (C_entries): Use it.
+ (C_entries): Several cosmetic changes.
+ (C_entries): Invalidate the token is some cases.
+
+2002-08-29 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (C_entries): Corrected a problem with const C++ funcs.

+
+2002-08-28 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (HTML_labels): Tag ID= also.
+
+2002-08-27 Francesco Potorti` <pot@gnu.org>

+
+2002-06-21 Francesco Potorti` <pot@gnu.org>

+ (get_tag): Prototype changed, all callers changed.
+
+2002-06-20 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c: Use, together with etags.el, an optimised form of tags,
+ which are almost always unnamed. etags.el looks for an explicit
+ tag name, then for an implicit one. See make_tag for details.
+ The change is both forwards and backwards compatible.
+ (make_tag): New function (was the disabled function new_pfnote).
+ (make_C_tag): Use it.
+
+2002-06-19 Francesco Potorti` <pot@gnu.org>

+ (readline): Conditionally undo readline_internal increment.
+ (readline): Do not return a value.
+
+2002-06-06 Francesco Potorti` <pot@gnu.org>

+
+2002-05-31 Paul Eggert <eggert@twinsun.com>
+
+ * etags.c (main): Use `sort -o TAGFILE TAGFILE' instead of
+ `sort TAGFILE -o TAGFILE', as POSIX 1003.1-2001 disallows
+ the latter usage.
+
+2002-04-22 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c: (last_node): Make it a global variable.
+ (process_file): Print the tags from the nodes as soon as
+ possible, and delete the nodes. This brings down the memory
+ occupancy as etags to almost the same level as when the #line
+ directives were not parsed.
+ (free_fdesc): New function.
+ (find_entries): Use it.
+ (invalidate_nodes): In etags mode, do not just mark the nodes as
+ invalid, do delete them.

+
+2002-04-13 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (find_entries): Delete tags previously obtained from
+ file xxx.c's #line directives when parsing file xxx.y. This is
+ generally done for automatically generated files containing
+ #line directives. This handles the case when xxx.y is tagged
+ before xxx.c, and the entries of xxx.c pointing to xxx.y should
+ be discarded.
+ (language): Added the metasource member. Initializers changed.
+ (invalidate_nodes): New function.
+
+2002-03-21 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (readline): Discard lines after having found a #line
+ directive pointing to an already tagged file. This handles the
+ case when xxx.y is tagged before xxx.c, and the entries of
+ xxx.c pointing to xxx.y should be discarded.
+
+2002-03-15 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (fdesc): New structure for keeping track of input files.
+ (fdesc): Remove `file' member (a string) and use instead a pointer
+ to a file description structure.
+ (curfile, curfiledir, curtagfname, curlang, nocharno,
+ forced_lang): Global variables removed in favor of fdhead and
+ curfdp, pointers to file description strucures.
+ (longopts, main, print_help): Use the CTAGS conditional to include
+ or exclude options that work on etags or ctags only.
+ (process_file, find_entries, pfnote, add_node, put_entries,
+ readline): Use fdhead and curfdp.
+ (process_file, find_entries): Do not take an arg string, all
+ callers changed.
+
+2002-03-13 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (longopts, print_help, main): Test CTAGS to disallow
+ options that are not right for either etags or ctags.
+
+2002-03-12 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (number_len, total_size_of_entries): Define them also
+ in CTAGS mode, because gcc does not compile all refs away.
+ (Python_functions, PHP_functions): Name tags, for ctags' sake.
+ (TeX_commands): Name tags. Correction of old disabled code.
+
+2002-03-06 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (Python_functions): Consider indented "def" and "class".
+
+2002-03-05 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (curfiledir, curtagfname): New global variables.
+ (process_file): Initialise them.
+ (readline): Canonicalize the name found in #line directive.
+
+2002-03-05 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c: Honour #line directives.
+ (no_line_directive): New global var; set it for old behaviour.
+ (main): Remove some #ifdef in the getopt switch.
+ (add_node, put_entries): Code added to merge different chunks of
+ nodes referring to the same file. Currently the tags are just
+ appended, without any check for duplicates.
+ (Perl_functions): Do not special case ctags.
+ (readline): Identify #line directives and do the right thing.
+ (nocharno, invalidcharno): New global vars.
+ (process_file): Reset nocharno.
+ (readline): Set nocharno.
+ (pfnote): Read nocharno and maybe put invalidcharno in node.
+ (total_size_of_entries, put_entries): Use invalidcharno.
+
+2002-03-04 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c: Keep the whole tag table in memory, even in etags mode.

+ (process_file): Do not call put_entries after parsing each file.
+ (process_file): Canonicalise file names even for ctags.
+ (process_file): Set curfile here...
+ (find_entries): ... not here any more.
+ (add_node): In etags mode, build a linked list of entries (on
+ right pointer) for each file, and link the first entry of each
+ file on left nodes.
+ (put_entries): Print here the name of the file.
+ (put_entries): Print the entries starting from the first file.
+ (number_len, total_size_of_entries): Define these only iin etags
+ mode, make the second work only on the right nodes.
+
+2002-01-03 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c: Make all global variables static.

+ [HAVE_CONFIG_H]: Let config.h deal with __P.
+ [__STDC__] [!HAVE_CONFIG_H]: Define PTR as in config.h.
+ [!__STDC__] [!HAVE_CONFIG_H]: Do not undefine static, because
+ gperf code needs it.
+ [HAVE_CONFIG_H] [!PTR]: Define PTR (for use with Xemacs).
+ [HAVE_CONFIG_H] [!__P]: Define __P (for use with Xemacs).
+ (xmalloc, xrealloc): Use PTR instead of long *.
+ (bool): Make it a define, not a typedef, for C++ compilers.

+ (get_language_from_langname): Use const argument.
+
+2001-12-12 Francesco Potorti` <pot@gnu.org>
+

+ heavily adapted by me, for parsing PHP.
+ (LOOKING_AT): New macro.
+ (Perl_functions, Python_functions, PHP_functions)
+ (Scheme_functions, Texinfo_nodes): Use it.
+ (Perl_functions): Use strneq.
+ (prolog_pred): Renamed to prolog_pr.
+ (prolog_pr): Recognise Prolog rules (thanks to Geert Kloosterman)
+ in addition to predicates.
+ [ETAGS_REGEXPS] [!HAVE_CONFIG_H] [__CYGWIN__]: Prevent
+ unmodified compile, as Cygwin's regex.h is incompatible with us
+ (thanks to Markus Hoenicka).
+ [!HAVE_CONFIG_H] [!__STDC__]: #define const as the empty string.
+
+2001-05-11 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (add_regex): Reset the whole newly allocated pattern
+ buffer instead of the individual members. It's safer and works
+ with Xemacs.
+
+2001-02-23 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c (enum sym_type): New label st_C_template.

+
+2001-01-31 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c: [NDEBUG] #undef assert and #define it as ((void)0), for
+ the sake of some buggy assert.h (e.g. in MinGW and sunos4 pcc).
+ (C_entries): Tag token renamed to still_in_token because sunos4
+ pcc wants to expand it as the token() macro even though it has no
+ arguments.
+
+2001-01-30 Francesco Potorti` <pot@gnu.org>
+
+ * etags.c: [WIN32-NATIVE]: #undef MSDOS, #undef WINDOWSNT and
+ #define it for the sake of Xemacs.
+ [WINDOWSNT]: #undef HAVE_NTGUI even if built without
+ HAVE_CONFIG_H. This change only affects a standalone etags.
+ [WINDOWSNT]: #undef DOS_NT and #define it even if built with
+ HAVE_CONFIG_H. This change does nothing in Emacs, as DOS_NT is
+ always defined when HAVE_CONFIG_H and WINDOWS are both defined.
+ [!HAVE_UNISTD_H]: use defined(WINDOWSNT) instead of the bare
+ WINDOWSNT, as this is the correct way to use it.
+
+2001-01-28 Francesco Potorti` <pot@gnu.org>

+ (C_entries): Tag C++ forward declarations if --declarations.
+ (C_entries): Don't be fooled by things like XDEFUN.
+ (consider_token): Discard asm pseudo function.
+
