GNU GLOBAL source code tagging system GNU GLOBAL is a software which makes your hack and review efficient by adding indexes to your software souce code. You can locate specified symbols in the source files and move there quickly. It is useful for hacking a large project containing many subdirectories, many #ifdef and many main() functions. It is similar to ctags or etags but is different from them at the point of indeppendence of any editor. GNU GLOBAL is Free Software based on GNU GPLv3 and a commercial software based on BOKIN model . We are [NEW] recruiting commercial licensees . BOKIN Model GNU GLOBAL Project Home Page Download GNU GLOBAL GNU GLOBAL Tutorial (2011/9/14) We are going to exhibit a book of the title 'GNU GLOBAL handbook'. It is not a mere manual but a book which explains the concepts and usages of GLOBAL in detail. The publication will be a schedule of the beginning next year.  Motive We planned an source code tagging system which meets the following requirement: Available from diverse environments Though there are a lot of tools which support analysis of source code, most of them are designed on the assumption of the use from original user interface and are not implemented to combine with other tools. As a result, if you select a certain tool then you must throw away other tools or alternately use them without the relation. Then we decided that we should make a pure tagging system which can be called from diverse environments. Applicable to large-scale projects Though the scale of software increases more day by day, most conventional tagging systems are made on the assumption of a comparatively small-scale project. Therefore we planned to make a new tagging system which can quickly find objects in a large-scale project, and can treat deep directory structure.  Feature work as a source code tagging system in various environments. find the locations of a specified object quickly. locate not only object definitions but also object references. locate also path which includes specified pattern. treat a source tree containing subdirectories as a logical scope. search not only in a source tree but also in library paths. understand POSIX 1003.2 regular expressions. the functions of grep(1) is built-in. support external search engine id-utils(1). generate hypertext of source code (XHTML ready). tag files are independent of machine architecture. plugged-in parser is available to treat new language. compact format is available to save disk space. support incremental updating of tag files. support customizing with gtags.conf and style.css. generate completion list for completing input method. Please see "Comparison with Similar Tools" page in the OpenGrok project site for comparison with other tools.  Support environment Supported OS GNU system - Debian, Fedora, Suse BSD system - FreeBSD, NetBSD, OpenBSD, MacOSX Various POSIX compatible system Support language: C C++ Yacc Java PHP4 Support environment Shell command line Bash shell Various Vi editor(nvi,elvis,vim) Emacs editor(emacs, mule, xemacs) Less viewer Various Web browser Doxygen documentation system  Ralated links GNU GLOBAL Project Home Page GNU GLOBAL Tutorial Sample of hypertext generated by GNU GLOBAL  Outside related links GNU GLOBAL Tutorial to read source code pleasantly[japanese only]  License Distribution condition: You can redistribute this software freely under the GNU GPLv3 (General Public License).
