== See diffs when editing commit message with VIM ==

'''NOTE:''' This instruction is no more actual. Recent versions of [[hgeditor]] do everything below automatically.

Make a private copy of the [[hgeditor]] script provided with Mercurial and replace the call to the editor with following command:

{{{
vim "+e $HGTMP/diff" '+set buftype=help filetype=diff' "+vsplit $HGTMP/msg" || exit $?
}}}

This will start up VIM in vertical split mode with commit message in the left pane and diff in the right pane. The {{{buftype=help}}} setting for diff window tells vim to exit when all other windows are closed, so when you write and quit the log with {{{:x}}} ({{{:wq}}} - they are equivalent), vim exits. If you have syntax highlight set up, the diff will be properly highlighted.

This setting is suitable for wide terminals. If you have a narrow terminal, you may want to replace the {{{+vsplit}}} above with {{{+split}}} or add {{{nowrap}}} to the {{{+set}}}.
