Action fails when add or remove only contain a space

[xenoterracide]

I suppose what I could do here is simply have 2 steps with conditionals, but that would end up with 2 commits which seems less elegant. Might be nice if it checked for empty and then did nothing on empty (except maybe log a warning).

seems like this would be a problem for me with add as well if I had only deleted files

Hi, thanks for the report! You're right, you could do separate steps with checks, but it's really counter-intuitive that an empty string causes the action to fail, also because the default value for remove is actually an empty string.
The problem comes from the fact that that string technically isn't empty, but it contains a space character ' '. I'll solve this by trimming the add and remove strings, so that strings like that will become empty.

hmm, strange... it's not just that maybe, I split it into 2 actions, and add still blows up, trim might still fix it though.

I'm going to bed, too tired to know what I'm talking about, but in the event it helps, this is my current full source code (in this branch) https://github.com/xenoterracide/iw-ppm-backend/tree/ccushing/plantuml . this comment will of course eventually be stale.

I think I fixed the issue.
The problem was not with the empty string, but with the one that was not: looking at your run logs I saw that the input string contained multiple spaces, and that was causing the action to parse some elements as empty strings. When the package that handles git commands saw one of these, it would complain about it being empty, even though your input was not.
I solved it by replacing the current parsing system (which only used split(' ') with a proper regex to parse paths and arguments.

The fix is currently on the master branch, and works with the test workflow I used to reproduce the issue. Can you try to see if that solves your problem too? Just use the action from that branch with

sorry I haven't tested this yet (sort of) I've been tracking down other bugs whilst trying to ensure this is working... and found many in my code. Not certain if this is part of this though, but it's kind of frustrating that something is being passed, but the build is not failing when it's missing.

The action will not stop if git commands fail because they don't match any file, this is intended behavior.
If you want the workflow run to fail in this situation you'll have to either run a custom command or use an action like [this].(https://github.com/marketplace/actions/file-existence)

Please test EndBug/add-and-commit@master as soon as you can, thank you.

Oh, I got it tested last night finally. It seems to work now
