Doom-emacs: Cannot backspace-delete in web mode

[skosch]

When in web-mode, RJSX, or similar, I occasionally cannot delete characters using backspace.

For instance, create a new file, turn on web-mode, and enter (| is your cursor):

(
<|>
)
<>

then hit backspace. Instead of deleting the <, I get an error Args out of range: #("<" 0 1 (part-side jsx ....

If this is an issue with one of the mode packages, I'll close this issue and ask there.

Thanks :)

This is certainly a configuration issue on Doom's side. Doom tries very hard to tame smartparens, but there will always be edge cases like these.

Please try the following and let me know if that fixes your issue.

(after! smartparens-html
  (setq sp-navigate-consider-sgml-tags nil))

[skosch]

Yes, that fixes it :)

@hlissner I'm getting a similar issue with elixir-mode, but the error is:

sp--skip-match-p: Symbol's function definition is void: sp-elixir-skip-def-p

If you'd like, I can open a new issue for it, since it is a bit different.

[skosch]

Oh yeah, that elixir-mode error looks awfully familiar to me as well ...

[hlissner]

Could you try removing this line in modules/lang/elixir/config.el (line 12) and see if that fixes that issue?

[bitwalker]

@hlissner That does fix it! I hadn't tried that since I figured it was needed, but so far I haven't noticed any issues. If something comes up I'll open a new issue. Thanks!

[hlissner]

Alright, both the original and new sp-elixir-skip-def-p issues should be resolved as of cba5270. Let me know if that isn't the case!
