Function arguments autocomplete for Odin LSP server

[CortexReaver]

Subj, recently I tried to setup LSP for Odin on Cudatext and overall it worked, but still I cannot figure out how to enable API functions auto suggestions. Seems like Odin LSP does support it, because I've seen how it working with LSP in Sublime:

or it can suggests some variables

But no such suggestions in Cudetext. Is this will be even possible to implement or not?

Does Sublime have some settings for Odin server, maybe in some config file? Maybe Sublime uses some middleware python code to configure Odin server? I cannot find it in the PackageControl.io site.

[CortexReaver]

So it does work for other languages? Because I've tried it only with C and Odin.
I will try Odin LSP with Sublime later.

[Alexey-T]

Yes, Cud's LSP plugin works good with many languages eg C++ and Python, as documented in the wiki page "cudatext plugins".

I asked for help at the Github issue linked above this post. Maybe you should click Cud's LSP sidebar icon, panel will be shown at the bottom. Read its log. Maybe LSP server was not inited ok?

[CortexReaver]

This is how it looks for me:

syntaxis suggestions works perfectly, that for sure. Is it supposed to be like this? Maybe I've hide the log somehow?

[CortexReaver]

My lsp_odin.json in the "cudatext\settings" folder:

{
  "lexers": {
    "Odin": "odin"
  },
    "cmd_windows": [
    "ols.exe"
  ],
	"enable_semantic_tokens": true,
	"enable_document_symbols": true,
	"enable_hover": true,
	"enable_snippets": true
}

Do I need to copy it anywhere else?

Installed LSP plugin with Lexer Odin on clean version or Cudatext:

No result.

I cannot make Odin server showing anything, so cannot help.+

• installed MS Build Tools 2022
• unzipped Odin last release, added dir to PATH
• unzipped LSP server, added it to PATH, renamed .exe file to ols.exe
• made settings/lsp_odin.json

{
  "lexers": {
    "Odin": "odin"
  },
  "cmd_windows": [ "C:\\Work\\odin_server\\ols.exe" ],
	"enable_semantic_tokens": true,
	"enable_document_symbols": true,
	"enable_hover": true,
	"enable_snippets": true,
	"enable_format": true,
	"log_stderr": true
}

from Console, odin.exe works, ols.exe works somehow too.
now from Cud, I see in Console panel

LSP: starting server - Odin; root: None
Init: cuda_runner
Init: cudatext
LSP: Odin - process exited

and now autocompletion don't work for your file 'new.odin' here: prin|t. LSP panel in Cud shows only 1 error:

stderr: D:/a/ols/ols/src/server/requests.odin(1450:58) Index 0 is out of range 0..<0

Is "MS Build Tools 2022" a requeirment?
Bcause I've used this script: https://gist.github.com/mmozeiko/7f3162ec2988e81e56d5c4e22cde9977
Since this is in the oficial Odin guide: https://odin-lang.org/docs/install/

[Alexey-T]

I am not sure MSBuildTools are used during lsp action.
I think this Console line

LSP: Odin - process exited

means that lsp server exits. So it dont work for me. If you have idea how to fix it, tell me.

[Alexey-T]

I found why 'process exited'! reason: I did not create PROJECT with tst.odin file which I edit. after I made the project and saved it as tst.cuda-proj in the same dir as tst.odin, completions work!

tst.odin

package tst;

import "core:fmt";

main :: proc(){
	value: u128;
	using fmt;
	print()
}

proof that it works:

my settings/lsp_odin.json.

{
  "lexers": {
    "Odin": "odin"
  },
  "cmd_windows": [ "ols.exe" ]
}

note that I copied ols.exe to the same dir as odin.exe.

I wrote my results to the wiki.
https://wiki.freepascal.org/CudaText_plugins#LSP_server_for_Odin

[Alexey-T]

Functions call-tooltip works too! good! I press Ctrl+Shift+Space here:

print(|)

[CortexReaver]

No luck, now I've got this error when I try to press shft+ctrl+space inside function parentheses:

[Alexey-T]

This error log shows that you have very old LSP_Client plugin! it is using already deleted api. update LSP_Client from 'plugins / addon manager / update'.

[CortexReaver]

Ok, now it works. One more thing: "base" folder from odin main folder must be included in a project (root nodes -> add folder) in order for LSP to work correctly.

Added this info to the wiki topic.
