Yes, let's do that for now. I'll get an account if this becomes a habit. Thanks for your help!

I thought this phabricator review served as a push request? How can I push the revision myself? Can I push directly on annongit.kde.org? (Sorry for being yet again a newb!)

Will do. Thanks!

I... git cloned ktexteditor and ran cmake .? Is there a better way? Sorry, I'm a real newb in this as you can probably tell! I'm not a dev by training.

OK. So, that'll require compile ktexteditor from source. I should be able to manage that (I guess?). I'll report here if it gives me too many headaches. I tried today, but gave up because of an issue with ECM (?) version. I got:

That's the thing: I don't know how to run the test. If it requires dealing with cmake and stuff, that's take me a while to figure out. Is there any simple documentation about it?

So, basically, I just write a bunch of tests, commit them here and we'll debug them if needed from here?

Say that I have the files for a unit test (origin, input.js and expected). How can I check the code for the unit test? Is there a way to simply execute the javascript code and verify it does what I expect? It would be a shame to have the unit test fail because of the code test itself.

I might get to that around September (no promise). If people are willing to help, my not-unit-at-all test code for indentation can be found here:

Just to say: this didn't fall off my radar. I'm just incredibly busy nowadays and it never quite make it to the top of my todo list... But I think about doing it regularly, which is a good sign it'll happen!

I will have a go at it. It doesn't seem very complicated indeed, but I just don't have much time right now for this.

I think this is very cool. But there is one thing we require for new indenters: unit tests.

There is a subfolder autotest in the KTextEditor git module. Could you have a look into this? Without such automated tests, we will likely introduce regressions in future updates of the indenter. If you need help, please let us know :-)
