@ -394,16 +394,20 @@ Example:
g:tagbar_ctags_options
Default: undefined
Use this option to specify the '--options' flag for the ctags executable,
reading in an additional ctags configuration file. This is similar to the
deffile key for tagbar type extensions, see |tagbar-extend|, but acts
globally.
Use this option to specify a list of filenames to pass to ctags with the
'--options' flag. This is similar to the deffile key for tagbar type
extensions, see |tagbar-extend|, but acts globally. The special value 'NONE'
as the first entry disables reading of the default configuration files (e.g.
~/.ctags). Without this, if ~/.ctags and other files listed in
g:tagbar_ctags_options include some of the same patterns, tagbar might show
duplicate entries.
Example:
>
let g:tagbar_ctags_options = split(&rtp,",")[0].'/ctags.cnf'
let g:tagbar_ctags_options = ['NONE', split(&rtp,",")[0].'/ctags.cnf']
This makes sure that ctags is called with options from ~/.vim/ctags.cnf
This causes ctags to use settings from ~/.vim/ctags.cnf, ignoring other
configuration files.
