Vim - show diff on commit in mercurial;
- by JackLeo
In my .hgrc I can provide an editor or a command to launch an editor with options on commit.
I want to write a method or alias that launches $ hg ci, it would not only open up message in Vim, but also would split window and there print out $ hg diff.
I know that I can give parameters to vim by using +{command} option. So launching $ vim "+vsplit" does the split but any other options goes to first opened window. So I assume i need a specific function, yet I have no experience in writing my own Vim scripts.
The script should:
Open new vertical split with empty buffer (with vnew possibly)
In empty buffer launch :.!hg diff
Set empty buffer file type as diff :set ft=diff
I've written such function:
function! HgCiDiff()
vnew
:.!hg diff
set ft=diff
endfunction
And in .hgrc I've added option: editor = vim "+HgCiDiff()"
It kind of works, but I would like that splited window would be in right side (now it opens up in left) and mercurial message would be focused window. Also :wq could be setted as temporary shortcut to :wq<CR>:q! (having an assumption that mercurial message is is focused).
Any suggestions to make this a bit more useful and less chunky?
UPDATE: I found vim split guide so changing vnew with rightbelow vnew opens up diff on the right side.
