auto-pairs: underscore _

[Indyandie]

Summary

It seems that underscores (_) don't seem to work for pairing.

Reproduction Steps

I tried this:

1. updated my config.toml

[editor.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
'`' = '`'
'<' = '>'
'*' = '*'
"_" = "_"
'~' = '~'

I expected an auto pair (__) when I tap the _ key

The * and ~ auto pair as expected.

Instead, a single _ appears.

I can't reproduce this unless I switch to a language that already has custom auto-pairs set, for example Rust:

helix/languages.toml

Lines 183 to 199 in 090ed97

	[[language]]
	name = "rust"
	scope = "source.rust"
	injection-regex = "rust"
	file-types = ["rs"]
	roots = ["Cargo.toml", "Cargo.lock"]
	auto-format = true
	comment-token = "//"
	language-servers = [ "rust-analyzer" ]
	indent = { tab-width = 4, unit = " " }
	[language.auto-pairs]
	'(' = ')'
	'{' = '}'
	'[' = ']'
	'"' = '"'
	'`' = '`'

For that case you should add new auto-pairs like _ to that language config.

🙇 Thanks for confirming @the-mikedavis and my apologies looks like it's working as expected. Not sure if it was a reboot or if I'm just blind.

To your point on adding the auto-pairs to the language config, that was my first attempt using markdown. Unfortunately, that didn't seem to work and I took the editor.auto-pairs route.

[[language]]
name = "markdown"
scope = "source.markdown"

[language.auto-pairs]
"_" = "_"
'*' = '*'
