1. INTRO *HGRevIntro*
HGRev is a small plugin that can find the current buffer's revision ID from a
Mercurial repository. For more information on Mercurial, see:
http://mercurial.selenic.com/
It is intended for use in the |statusline|- here's an example to enable it:
set statusline=[r%{HGRev()}] ~
HGRev exports the 'HGRev()' function (for use in the statusline), and a
command called
>
:RefreshMercurialRev
Which you can use to manually update the revision information for the current
buffer. If you've added HGRev() to your statusline, you'll see the file
revision, branch, tags, and file status reflected -- if you used the
statusline example above, you should see something like this:
[r192+ default tip M] ~
The information displayed can be easily customized, and HGRev can also
automatically update the status line on file changes. (This behavior is
disabled by default.)
==============================================================================
2. CONFIGURATION-OPTIONS *HGRevOptions*
Here are the available configuration options and their defaults:
>
let g:hgrevFlags = '-nbt'
let g:hgrevAddStatus = 1
let g:hgrevAutoUpdate = 0
let g:hgrevNoRepoChar = '-'
------------------------------------------------------------------------------
2.1 *g:hgrevFlags*
These are the flags passed directly to 'hg id'. The flags "-nbt" are passed
by default, which show a local rev id, branch, and tags.
If you wanted to show the global rev hash (and nothing else) as an example,
you can set this to:
>
let g:hgrevFlags = '-i'
------------------------------------------------------------------------------
2.2 *g:hgrevAddStatus*
This settings will append the current file status to the output, by running
'hg stat'. I find it useful, so it is enabled by default -- you can disable
it like so:
>
let g:hgrevAddStatus = 0
>
------------------------------------------------------------------------------
2.3 *g:hgrevAutoUpdate*
>
When this option is enabled, some |autocmd-events| are added that
automatically call :RefreshMercurialRev on file changes -- when a buffer is
read, written to, or modified outside of Vim. This is disabled by default, as
the additional time needed (however small) to system() to hg for every
read/write outweighs running :RefreshMercurialRev manually for my tastes.
Yours tastes, of course, may vary, so you can enable it like so:
>
let g:hgrevAutoUpdate = 1
Alternatively, you can leave it disabled, and add your own |autocmd| events
for :RefreshMercurialRev to what works best for you.
------------------------------------------------------------------------------
2.4 *g:hgrevNoRepoChar*
>
If the current buffer doesn't seem to be a member of a Mercurial repository,
HGRev() returns this character instead of a revision ID.
Some examples:
>
let g:hgrevNoRepoChar = '-' (default)
set statusline=[r%{HGRev()}]
This will output something like '[r12+ default tip M]' for repo files,
and '[r-]' for non-repo.
>
let g:hgrevNoRepoChar = ''
set statusline=%{HGRev()?'[r'.HGRev().']':''}
This will output something like '[r512 default tip]' for repo files, and
nothing at all for non-repo.
