gen_tags.vim

Async plugin for Vim/NeoVim to ease the use of ctags/gtags.
It is used for generate and maintain tags for you with multiple platform support, tested on Windows/Linux/macOS.

gen_tags.vim will detect SCM(git, hg, svn) root and use it as the project root path. But you can also create a folder named as .root to specify a directory as the project root path.

Generate/Update ctags and gtags will run in background.

Difference between ctags and gtags

GNU global(aka gtags) is more powerful than ctags, which support definition, reference, calling, called, include, string and etc, but ctags only support definition.

As we can use GNU global why did I still support ctags in this plugin?
That's because GNU global only support 6 languages (C, C++, Yacc, Java, PHP4 and assembly) natively.
ctags can support more languages(41 showed on the website).

Actually global can support more languages with Pygments plugin parser, for more details please refer PLUGIN_HOWTO.pygments in global document.
