Configuration

Project Configuration

Set project specific configuration. Project is specified with $GTAGSROOT if configured,
otherwise with result of fnamemodify('.', ':p'), usually current dir described as absolute path '/' added.

Following items are configured for each project:

  • treelize (0 or 1): show Unite's items in tree format or not
  • absolute_path (0 or 1): add -a option to global command or not
  • gtags_libpath (list of string): join with ':' and use it as GTAGSLIBPATH
  • through_all_tags (0 or 1): add --through option to global command or not

You can set default configuration with specifying _ as project name.

Configuration Example:

g:unite_source_gtags_project_config = {
  \ '/home/foo/project1/': { 'treelize': 0 },
  \ '_':                   { 'treelize': 1 }
  \ }
" specify your project path as key.
" '_' in key means default configuration.

treelize

When treelize = 1, unite result is grouped by filepath and enable you to select a candidate with tree like interface.
This format is effective when filepath is too long string.

Default format:

sample1/foo.rb  |2|  def hoge
sample1/foo.rb  |6|    hoge
sample2/bar.rb  |4|    hoge

Tree format:

[path] sample1/foo.rb
|2|  def hoge
|6|    hoge
[path] sample2/bar.rb
|4|    hoge

absolute_path

When absolute_path = 1, unite-gtags add -a option to global command.
Path in unite's items changes to absolute path format.

Relative path (default):

sample1/foo.rb |2|   def hoge
sample1/foo.rb |6|     hoge
sample2/bar.rb |4|     hoge

Absolute path:

/home/foo/sample1/foo.rb |2|   def hoge
/home/foo/sample1/foo.rb |6|     hoge
/home/foo/sample2/bar.rb |4|     hoge

gtags_libpath

When gtags_libpath is specified with list of string,
unite-gtags joins them with ':' and use the joined string as GTAGSLIBPATH.
(This feature is only available in *nix system.)

Example:

When configure gtags_libpath with following

let g:unite_source_gtags_project_config[<cur_dir>] = {
\ 'gtags_libpath': ['/usr/include/', '/home/foo/include/']
\ }

unite-gtags executes global with temporary environment variable GTAGSLIBPATH like below

GTAGSLIBPATH=$GTAGSLIBPATH:/usr/include/:/home/foo/include/ global ...

through_all_tags

By default, a search is ended without go through all the tag files listed in GTAGSLIBPATH when tags are found in a project's tag file. This behavior may be unintended if there are definitions with the same name as the one defined in a project.

When through_all_tags = 1, unite-gtags adds --through option to global command and it makes a search go through all the tag files listed in GTAGSLIBPATH. This option is ignored when either -s, -r or -l option is specified.

Syntax Highlight
