@unnumberedsubsec NAME
gtags-parser - print cross reference list for gtags.
@unnumberedsubsec SYNOPSIS

@end quotation
@unnumberedsubsec DESCRIPTION
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 @samp{-x} option.

Depending upon the options provided to gtags-parser,
objects will consist of function definitions, function references
and other symbols.

Files whose names end in @file{.c} or @file{.h} are assumed to be C
source files and are searched for C style routine and macro definitions.
Files whose names end in @file{.c++} @file{.cc} @file{.cpp}
@file{.cxx} @file{.hxx} @file{.hpp} @file{.C} @file{.H} are assumed to be C++
source files.
Files whose names end in @file{.y} are assumed to be YACC source files.
Files whose names end in @file{.java} are assumed to be Java source files.
Files whose names end in @file{.php} @file{.php3} @file{.phtml} are
assumed to be PHP source files.
Files whose names end in @file{.s} or @file{.S} are assumed to be
Assembler 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.
@unnumberedsubsec OPTIONS
The following options are available:
@table @asis
@item @samp{-b}, @samp{--begin-block}
Force level 1 block to begin when reach a left brace at the first column.
(C only)
@item @samp{-d}, @samp{--define}
Pick up not only function but also macro without argument
as a definition.
@item @samp{-e}, @samp{--end-block}
Force level 1 block to end when reach a right brace at the first column.
(C only)
@item @samp{-n}, @samp{--no-tags}
Suppress output of tags. It is useful to use with @samp{-w} option.
@item @samp{-r}, @samp{--reference}
Locate function references instead of function definitions.
@file{GTAGS} is needed at the current directory.
(C, C++ and Java source only)
By default, locate function definitions.
@item @samp{-s}, @samp{--symbol}
Collect symbols other than functions.
By default, locate function definitions.
@item @samp{-t}, @samp{--typedef}
Pick up not only function but also typedef name and enum member
as a definition.
@item @samp{-v}, @samp{--verbose}
Verbose mode.
@item @samp{-w}, @samp{--warning}
Print warning message.
@item @samp{--langmap}=map
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,cpp:.c++.cc.cpp.cxx.hxx.hpp.C.H,php:.php.php3.phtml'.
@end table

The @samp{-r} and @samp{-s} options override each other;
the last one specified determines the method used.
@unnumberedsubsec DIAGNOSTICS
Gtags-parser exits with a non 0 value if an error occurred, 0 otherwise.
Duplicate objects are not considered errors.

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

Assembler support is far from complete.
Probably valid only for FreeBSD and Linux kernel source.
