x doesn't work like in evil about evil-smartparens

[blaenk]

Hmmm, I see it seems to be because it gets bound to sp-delete-char here https://github.com/expez/evil-smartparens/blob/master/evil-smartparens.el#L128 That function should probably take a parameter to specify whether to kill/copy the text or not, like delete-char does, but I guess that's not an issue of this project. It could probably be worked-around though by copying the text before calling that function.

Making x and X work like they do in evil-mode is going to be more work that its worth for me right now. These functions also allow you to select a region to delete, and registers, but that's also not supported atm.

I suppose I'm not a very advanced vim user (coming to it from emacs). I only ever hit x when I want to delete a single char :/ It actually never occurred to me that I could use the combination xp to transpose a char--that's awesome!

If you want to take a dive into extending evil, then a pull request would be most welcome.

[blaenk]

No worries, it's not that big of a deal and can easily be worked around.

[expez]

Let me know if this does the trick or not! I'd love it if you gave this a try before I tagged a release for melpa-stable.

[blaenk]

I'll check it out!

It seems to work! not sure if this is normal, but when I try to press 'x' on a closing paren I get this:

Yeah, this is expected when deleting the paren would result in an unbalanced buffer. I should probably change the error to user-error, though.

[expez]

erroring out like that is consistent with how evil-sp works when you try to do something objectionable using the other operators (e.g. visually selecting an unbalanced region and hitting d). The message is a little inappropriate in this case, though, because you're unlikely to be action on a region.

[blaenk]

That's fine, was just letting you know in case it wasn't expected. Nice work!

[expez]

Thanks for giving this a spin!
