Is there any way to hook saving in Vim up to commiting in git?

Question

I am new to the world of Vim, and I want to make it so that every time I save a file it is commited to version control. Is this possible?

Answer 1

I use a vim autocommand which I place in my .vimrc. The command first does a crude check that we're working in a git directory (by checking existence of a .git directory), then uses git -a -m % so that only files that have previously been added are staged and committed.

autocmd BufWritePost * execute '! if [ -d .git ]; then git commit -a -m %; fi

Answer 2

You surely could to this whit a macro or with command remapping.

(Check http://stackoverflow.com/questions/117150/can-i-re-map-commands-in-vim)

I'm not sure it's a good option though. I'm not proficient in git for now and I know it's sometimes different from svn. But I wouldn't do this auto-commit with svn. Commit needs to be meaningful and not some save at regular time.

You normally commit because you added a function, fixed a bug, ... not just because you worked on a file. You won't end up with non compiling project or unfinished function.

Answer 3

You could use Vim's autocommands:

:autocmd BufWritePost * execute '!git add % && git commit -m %'

That's untested but it should add the file and commit it with the filename as commit message.
You want BufWritePost as this is triggered after the file is written. I'd imagine there are a lot of irksome or unsafe edge cases though.

Answer 4

You may want to look into the fugitive plugin, it's a very powerful git plugin for vim. You can also setup an autocmd as donothingsuccessfully suggests, but have it pop up :Gcommit or :Gstatus (from which you can cherry pick changes to add to the git index)

Answer 5

Building on the answers others have provided:

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'

This is completely transparent. You won't get the "Press enter to continue" message (but if the commit didn't work, you won't know it failed).
