Warnings for empty folders triggered when using "elvis git-branch" about elvis_core HOT 6 OPEN

Hi, @cdyb-kivra. Thanks for the report.

I'm not sure what "using the git-branch subcommand to elvis" means 😕, though.

In any case, when the warning is issued, is it correct? (i.e. are the folders empty or non-existing?)

It was, indeed, not a concern of mine when developing it to assume different behaviours using branches, but I can revisit that.

Since it's a warning, and not an error (we did discussed it being an error, but didn't go that route) what would you suggest we do differently?

The git-branch subcommand is used to only run elvis on those files that have been changed compared to a given git branch. So, for example, my elvis.config points at three directories, src, test and include. Most of the time I work on a feature branch and change files in src and test. I then run the elvis git-branch command to get it to check only those files I have actually edited (compared to our main branch). With the latest elvis version, I then always get a warning about there being no files in include and that I should update my configuration. Which is not true. Since it's a warning, it's not really a problem, but it is annoying and it teaches to ignore warnings from elvis.

I haven't looked at how this is implemented, but offhand it feels like the check that triggers the warning should be applied before the git-branch filtering is done. Or, possibly, that the warning should just be suppressed entirely when the git-branch subcommand is running.

I agree it's no good.

I didn't know about elvis git-branch. I use elvis only as a plug-in, which is why I didn't consider that "edge" case.

I'm pulling @elbrujohalcon to this issue, since this'll probably also include changes to elvis.

This is the bit that seems to need some kind of tweaking in the code. elvis is "aware" of elvis_core but not the other way around, though they should play nice.

It's been ages since I last saw git-branch anywhere. I think that, instead of myself, you should pull @jfacorro here, @paulo-ferraz-oliveira.
Sorry, but I can help as much or even less than you on this topic.

At the company I work for (Kivra), we use elvis git-branch as part of our CI/CD pipeline. So it's not just me personally :-)

Sure. Let's wait for @jfacorro's input, then. We either have to silence elvis_core via an API variable, an option or, ... another thing (?)
