the LSP isn't exactly working for me? Autocomplete, docs for word under cursor?
Is this still work under progress?
Luke Boswell (Sep 28 2026 at 11:23):Yes the LSP is still being developed and lots of rough edges right now.
Luke Boswell (Sep 28 2026 at 11:24):Feel free to make GH Issues if you notice anything specific and have a nice repro :smile:
Adityavarman Manjunath (Sep 28 2026 at 11:24):wow, okay, but I love the language syntax.. also could you point me to any active discussion thread for the LS?
Luke Boswell (Sep 28 2026 at 11:29):None super recent.. I think this was the latest
A few different people have been chipping away at it and making PRs.
This week @notramo has made some GH Issues I think and Richard has already resolved those... so things ars moving fast.
Adityavarman Manjunath (Sep 28 2026 at 11:30):Got it!.. thanks @Luke Boswell
Luke Boswell (Sep 28 2026 at 11:31):Heres an example I guess

@Adityavarman Manjunath, I use Helix too, and these are working for me in the nightly-2026-09-27-a3ce7f1 version. From the screenshot, I see you are using this version also.
notramo (Sep 28 2026 at 13:44):Richard pushed some more fixes yesterday, which should make it into today's nightly, but those are around error diagnostics. The hover info fixes are already in the latest nightly.
Adityavarman Manjunath (Sep 28 2026 at 13:48):yea i just got the hover info working.. i had to restart helix for it and change a few things..
Adityavarman Manjunath (Sep 28 2026 at 18:56):just got a good base setup for helix if someone is looking for it:
use-grammars = { only = ["roc"] }
[language-server.roc-lsp]
command = "roc"
args = ["experimental-lsp", "--stdio"]
[[language]]
name = "roc"
scope = "source.roc"
injection-regex = "roc"
file-types = ["roc"]
shebangs = ["roc"]
roots = []
comment-token = "#"
language-servers = ["roc-lsp"]
indent = { tab-width = 4, unit = " " }
formatter = { command = "roc", args = ["fmt", "--stdin"] }
auto-format = true
[language.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
[[grammar]]
name = "roc"
source = { git = "https://github.com/faldor20/tree-sitter-roc.git", rev = "master"}
