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.
