问题
I use the following command in my vimrc to auto commit on save. I find this very useful. However I do not like that I am stuck with the same commit message every time.
autocmd BufWritePost * execute ':silent ! if git rev-parse --git-dir > /dev/null 2>&1 ; then git add % ; git commit -m "Auto-commit: saved %"; fi > /dev/null 2>&1'
What I would like is to receive a prompt when saving that allows me to either provide a commit message or press enter and use the "Auto-commit: saved %" as a default when I am in a hurry.
I played around with input() and didnt have any luck within this particular command.
I also attempted to use a value returned by a function but could not get that to work either.
回答1:
input() is a built-in function, you assign its result to a variable, and can then insert (with proper escaping) its contents into your external shell command:
autocmd BufWritePost * let message = input('Message? ', 'Auto-commit: saved ' . expand('%')) | execute ':silent ! if git rev-parse --git-dir > /dev/null 2>&1 ; then git add % ; git commit -m ' . shellescape(message, 1) . '; fi > /dev/null 2>&1'
This one will query on every save. With an added conditional, you could make it abort the commit when no message is given.
