GNU GLOBAL source code tag system

GNUGLOBAL是一款跨环境的源代码标记系统,适用于C、C++、Yacc、Java和PHP4等多种语言,可在多种编辑器及浏览器中使用。它支持查找对象定义和引用,适用于大型项目,并能理解正则表达式。此外,GNUGLOBAL还能生成源代码的超文本版本。
GNU GLOBAL is a source code tagging system that works the same wayacross diverse environments (emacs, vi, less, bash, web browser, etc).You can locate objects in source files and move there easily.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 ofindependence of any editor.It runs on a UNIX(POSIX) compatible operating system like GNU and BSD.

GNU GLOBAL is part of the GNU project,and is free software.You can freely copy, modify and redistribute this program underGNU GPL.

GNU GLOBAL is also commercial (for-profit) software based onBOKIN model.

GNU GLOBAL has following features:

  • support C, C++, Yacc, Java and PHP4.
  • work the same way across diverse environments. Currently, the following environments are supported:
    • Generic shell command line
    • Bash shell
    • Vi clone editor (nvi, elvis, vim)
    • Emacs editor
    • Less viewer
    • Web browser(See UNIX kernel source tour!.)
    • Doxygen documentation system
  • find locations of the specified object quickly.
  • locate not only object definitions but also object references.
  • allow duplicate objects.
  • locate paths which matches to the specified pattern.
  • treat a source tree containing subdirectories as a project.
  • search not only in a project but also in library paths.
  • understand POSIX 1003.2 regular expressions.
  • external search engine (grep and idutils) is available.
  • generate a hypertext of source code (XHTML ready).
  • tag files are independent of machine architecture.
  • plugged-in parser is available to treat new language.
  • compact format to save disk space.
  • incremental updating of tag files.
  • customizing with a configuration file (gtags.conf).
  • generate completion list for completing input method.
Please also see "Comparison with Similar Tools"in the OpenGrok project site for comparison with other tools.

If you have a plan to make a yet another editor with tag facility,you can use GLOBAL as the tag system.

Unless there is only one argument in the function and it is clear. # # * Never use macros. They allow overwriting global variables and this # makes variable declarations hard to locate. # # * If a target from add_custom_* is set in a function, explicitly pass it # as an output argument so that the target name is clear to the user. # # * Avoid use of global variables in functions. Functions in a nested # scope may use global variables, but this makes it difficult to # reuse functions. # # Included CMake Files # --------------------------------------------------------------------------- # # * All variables in config files must have the prefix "config_". # # * Never set global variables in an included cmake file, # you may only define functions. This excludes config and Toolchain files. # This makes it clear to the user when variables are being set or targets # are being created. # # * Setting a global variable in a CMakeLists.txt file is ok, because # each CMakeLists.txt file has scope in the current directory and all # subdirectories, so it is not truly global. # # * All toolchain files should be included in the cmake # directory and named Toolchain-"name".cmake. # # Misc # --------------------------------------------------------------------------- # # * If referencing a string variable, don't put it in quotes. # Don't do "${PX4_PLATFORM}" STREQUAL "posix", # instead type ${PX4_PLATFORM} STREQUAL "posix".
