gtags-parser: print cross reference list for gtags.

NAME

gtags-parser - print cross reference list for gtags.

SYNOPSIS

gtags-parser [-bdenqrstvw] file ...

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 -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.

OPTIONS

The following options are available:
-b, --begin-block
Force level 1 block to begin when reach the left brace at the first column. (C only)
-e, --end-block
Force level 1 block to end when reach the right brace at the first column. (C only)
-n, --no-tags
Suppress output of tags. It is useful to use with -w option.
-q, --quiet
Quiet mode.
-r, --reference
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.
-s, --symbol
Collect symbols other than object definitions and references. By default, locate object definitions.
-v, --verbose
Verbose mode.
-w, --warning
Print warning message.
--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'.

The -r and -s options override each other; the last one specified determines the method used.

ENVIRONMENT

The following environment variables affect the execution of gtags-parser:
GTAGSFORCECPP
If this variable is set, each file whose suffix is 'h' is treated as a C++ source file.

DIAGNOSTICS

Gtags-parser exits with a non 0 value if an error occurred, 0 otherwise. Duplicate objects are not considered errors.

BUG

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