|

" Script: autotags.vim
|
||||
" Author: Basil Gor <basil.gor at gmail.com>
|

" Homepage: http://github.com/basilgor/vim-autotags
|
||||
" Version: 1.0 (10 Oct 2012)
|
||||
" License: Redistribute under the same terms as Vim itself
|
||||
" Purpose: ctags and cscope tags handling
|
||||
" Documentation:
|
||||
" This script is a wrapper for ctags and cscope, so tags for all languages
|
||||
" supported by ctags can be build (cscope is additionally used for C/C++).
|
||||
"
|
||||
" Features
|
||||
" 1. No configuration needed
|
||||
" 2. Build/rebuild index for project with a single key stroke
|
||||
" 3. Tags are loaded then automatically when a file is opened anywhere in
|
||||
" project tree
|
||||
" 4. Tags are stored in a separate directory and don't clog you project tree
|
||||
" 5. Extra directories (like library source or includes) can be added with a
|
||||
" single key stroke too
|
||||
"
|
||||
" Put autotags.vim in your ~/.vim/plugin directory, open source code and
|
||||
" press F4 (map AutotagsUpdate to change it).
|
||||
"
|
||||
" You can reindex sources by pressing F4 again.
|
||||
"
|
||||
" To build and load additional tags for another directory (i.e. external
|
||||
" project or library code you want to navigate to) press F3 (or map
|
||||
" AutotagsAdd).
|
||||
"
|
||||
" Script builds and loads ctags and cscope databases via a single command.
|
||||
" All ctags and cscope files are stored in separate directory ~/.autotags by
|
||||
" default. You can set it via
|
||||
" let g:autotagsdir = $HOME."/boo"
|
||||
"
|
||||
" Project root directory will be asked when indexing new project. After that
|
||||
" tags will be loaded automatically when source files somewhere in project
|
||||
" tree are opened (if path contains project root).
|
||||
"
|
||||
" Exact tags location:
|
||||
" ~/.autotags/byhash/<source dir name hash>/<ctags and cscope files>
|
||||
"
|
||||
" Also `origin` symlink points back to source dir
|
||||
" ~/.autotags/byhash/<source dir name hash>/origin
|
||||
"
|
||||
" `include_*` symlinks point to additional tags for external directories
|
||||
" ~/.autotags/byhash/<source dir name hash>/include_*
|
||||
"
|
||||
" Tags for non-existing source directories are removed automatically
|
||||
" (checked at startup)
|
||||
"
|
||||
" Also ctags file ~/.autotags/global_tags is built for /usr/include once
|
||||
"
