GNU GLOBAL 5.7.1 (Default branch)
04-21-2008
GNU GLOBAL is a source code tagging system thatworks the same way across diverse environments(such as emacs, vi, less, bash, or a Web browser).It allows you to locate specified objects insource files and move there easily. It is usefulfor hacking a large project containing manysubdirectories, many #ifdef directives, and manymain() functions. It is similar to ctags or etags,but differs by being independent of any editor.|

GTAGS-PARSER(1) General Commands Manual GTAGS-PARSER(1) 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. SEE ALSO

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