Vlang syntax not work by default

[linc01]

Summary

Although there are some configurations available for Vlang in the languages.toml file by default, they do not seem to work as documented. Please advise on how to enable vlang-lsp, as it is working well with my Vim environment.

Thanks!

Thanks for opening an issue. Can you check if https://github.com/helix-editor/helix/wiki/Troubleshooting#missing-syntax-highlighting addresses your problem?

[linc01]

Thanks kirawi, here is:

Configured language server: vls
Binary for language server: Not found in $PATH
Configured debug adapter: None
Highlight queries: ✓
Textobject queries: ✘
Indent queries: ✘

and the vls $PATH(export PATH=~/.vls/bin/vls_linux_x64:$PATH) is there, but it's not found in the above check.

@linc01 PATH is a Unix environment variable that lists directories to search for binaries when running them by name. You can't add a binary directly to PATH.

Edit: I'm assuming bin/vls_linux_x64 is a binary, not a directory, just by convention. Apologies if that's not right.

[linc01]

@askreet Thank you for your response! Unfortunately, I have already attempted using the bin file at first, but not work.

Unfortunately, I have already attempted using the bin file at first, but not work.

When you added only the bin directory to your path, did hx --health v continue to show "Not found in $PATH"? If you have a binary called vls_linux_x64 in a directory called bin that will not work, as (per the output of --health) Helix is looking to find a binary called vls.

And it's not affect the syntax highlight, right?

Correct, the language server has nothing to do with syntax highlighting. The fact that your output shows Highlight queries: ✓ indicates the treesitter queries exist for the language and should be highlighting. Does the correct filetype show when you use :set-language?

I don't know anything about V or Vue, but hx --health v appears to want a language server called v while hx --health vue wants one called vls -- which type of file are you working with?

[linc01]

.v file for Vlang

this is the current highlight:

seems the highlight works, but not very well.

[kirawi]

That's quite different from "doesn't work by default." The highlighting queries for V result in simple highlighting: https://github.com/helix-editor/helix/blob/master/runtime/queries/v/highlights.scm

Someone would need to put in the work to get more detailed highlighting.

@linc01 do you by chance have the vue lsp setup on helix as well. I just V setup on my machine and saw the same thing you do but it looks like both vue lsp and V lsp are called vls and I think that is leading to a bug in helix

@linc01 @bfg-coding

Use ":lang" to get language id.

Probably this error is caused by a file type conflict， v and verilog both use v as the file suffix.

v

helix/languages.toml

Lines 1614 to 1617 in 3d230e7

	[[language]]
	name = "v"
	scope = "source.v"
	file-types = ["v", "vv"]

verilog

helix/languages.toml

Lines 1629 to 1632 in 3d230e7

	[[language]]
	name = "verilog"
	scope = "source.verilog"
	file-types = ["v", "vh", "sv", "svh"]

Custom configurations can be solved, append to .config/helix/languages.toml like this:

[[language]]
name = "v"
file-types = ["v", "vv"]

[[language]]
name = "verilog"
file-types = ["vh", "sv", "svh"]

there has remove "v" from verilog.

We can config statusline to show language id.

@askreet @bfg-coding @erasin @kirawi
:lang shows Bad arguments and :set-language v for vlang's .v file works. I've changed the languages.toml file and all looks good, it is the file type conflict.

Thanks guys!

[erasin]

:lang shows Bad arguments

Because I use the master branch，in new version,:lang is short of :set-language, when not input parameters, it will return the current language ID.

---

@kirawi There are have type conflicts in the languages.toml default configuration.

Thanks, looking forward to using the upcoming version. Helix is awesome!
