gtags-parser - print cross reference list for gtags.
gtags-parser [-bdenqrstvw] file ...
Gtags-parser print cross reference list for gtags(1) from the specified
C, C++, yacc, java, PHP and Assembly source to standard output. Each
line of output contains the object name, the line number which it
appears, the file in which it is defined, and a line image separated by
white-space. It’s same with the output of ctags(1) with -x option.
Depending upon the options provided to gtags-parser, objects will
consist of object definitions, object references and other symbols.
Files whose names end in ´.c´ or ´.h´ are assumed to be C source files.
Files whose names end in ´.c++´ ´.cc´ ´.cpp´ ´.cxx´ ´.hxx´ ´.hpp´ ´.C´
´.H´ are assumed to be C++ source files. Files whose names end in ´.y´
are assumed to be YACC source files. Files whose names end in ´.java´
are assumed to be Java source files. Files whose names end in ´.php´
´.php3´ ´.phtml´ are assumed to be PHP source files. Files whose names
end in ´.s´ or ´.S´ are assumed to be Assembly source files. Other
files are searched for C style definitions.
Yacc files each have a special tag. yyparse is the start of the second
section of the yacc file.
This command is the default parser of GLOBAL source code tag system.
The following options are available:
Force level 1 block to begin when reach the left brace at the
first column. (C only)
Force level 1 block to end when reach the right brace at the
first column. (C only)
Suppress output of tags. It is useful to use with -w option.
Locate object references instead of object definitions. ´GTAGS´
is needed at the current directory. (C, C++ and Java source
only) By default, locate object definitions.
Collect symbols other than object definitions and references.
By default, locate object definitions.
Print warning message.
Language mapping. Each comma-separated map consists of the
language name, a colon, and a list of file extensions. Default
mapping is ’c:.c.h,yacc:.y,asm:.s.S,java:.java,
The -r and -s options override each other; the last one specified
determines the method used.
The following environment variables affect the execution of gtags-
If this variable is set, each file whose suffix is ’h’ is
treated as a C++ source file.
Gtags-parser exits with a non 0 value if an error occurred, 0
otherwise. Duplicate objects are not considered errors.

Gtags-parser relies on the input being well formed, and any syntactical
errors will completely confuse it.
