Is your feature request related to a problem? Please describe.
Commit with gitui allow only one commit line, without commit description (like is allowed with commit -m command)

Describe the solution you'd like
Allow to add a description to the commit: with a new description field, or simply with a multi-line commit

If you press the Open editor key (default is ^e) while the commit window is open, you can edit the commit message using a text editor (similar to what git commit does).

Yes it did the trick thank you :)

Better to do that! Hope will be merged soon :D

I'm here for this same reason. A message in the commit window saying the user to press ctrl+e for multi-line commits, while we make something better, wouldn't hurt.

[extrawurst]

marking as good first issue, since its just about finishing the draft PR #509

Any updates on this? @extrawurst

I'll have a look to see if I can finish off #1309.

@extrawurst - are you open to assessing https://github.com/rhysd/tui-textarea/ for this purpose? I ask not yet knowing the gitui codebase (hence implications) nor your attitude to deps. I've tried a couple of the examples and it seems nice on the face of it not to have to roll-your-own scrolling & cursor etc. It might also have other uses within gitui perhaps?

If you're open to it I'll explore that route first briefly as a test of fit and report back. If not I'll disinter the above PR and see what I might do with it.

Ah. I see now there's an issue already suggesting use of tui-textarea, which should give us multiline input for free. So never mind for now. I'll keep an eye on that issue in case help's needed at any stage. It would be a good one to get over the line.
