Language server for Odin. This project is still in early development.
Note: This project is made to be up to date with the master branch of Odin.
cd ols
# for windows
./build.bat
# for linux and macos
./build.shIn order for the language server to index your files, it must know about your collections.
To do that you can either configure ols via an ols.json file (it should be located at the root of your workspace).
Or you can provide the configuration via your editor of choice.
Example of ols.json:
{
"$schema": "https://raw.githubusercontent.com/DanielGavin/ols/master/misc/ols.schema.json",
"collections": [
{ "name": "custom_collection", "path": "c:/path/to/collection" }
],
"enable_semantic_tokens": false,
"enable_document_symbols": true,
"enable_hover": true,
"enable_snippets": true,
"profile": "default",
"profiles": [
{ "name": "default", "checker_path": ["src"]},
{ "name": "linux_profile", "os": "linux", "checker_path": ["src/main.odin"]},
{ "name": "windows_profile", "os": "windows", "checker_path": ["src"]}
]
}You can also set ODIN_ROOT environment variable to the path where ols should look for core and vendor libraries.
Options:
enable_format: Turns on formatting with odinfmt. (Enabled by default)
enable_hover: Enables hover feature
enable_snippets: Turns on builtin snippets
enable_semantic_tokens: Turns on syntax highlighting.
enable_document_symbols: Turns on outline of all your global declarations in your document.
enable_fake_methods: Turn on fake methods completion. This is currently highly experimental.
enable_inlay_hints: Turn on inlay hints for editors that support it.
enable_procedure_snippet: Use snippets when completing procedures—adds parenthesis after the name. (Enabled by default)
enable_checker_only_saved: Turns on only calling the checker on the package being saved.
enable_references: Turns on finding references for a symbol. (Experimental)
enable_rename: Turns on renaming a symbol. (Experimental)
odin_command: Allows you to specify your Odin location, instead of just relying on the environment path.
checker_args: Pass custom arguments to odin check.
verbose: Logs warnings instead of just errors.
profile: What profile to currently use.
profiles: List of different profiles that describe the environment ols is running under.
Odinfmt reads configuration through odinfmt.json.
Example:
{
"$schema": "https://raw.githubusercontent.com/DanielGavin/ols/master/misc/odinfmt.schema.json",
"character_width": 80,
"tabs": true,
"tabs_width": 4
}Options:
character_width: How many characters it takes before it line breaks it.
spaces: How many spaces is in one indentation.
newline_limit: The limit of newlines between statements and declarations.
tabs: Tabs or spaces.
tabs_width: How many characters one tab represents
sort_imports: A boolean that defaults to true, which can be set to false to disable sorting imports.
Support Language server features:
- Completion
- Go to definition
- Semantic tokens
- Document symbols
- Rename
- References

Install the extension https://marketplace.visualstudio.com/items?itemName=DanielGavin.ols
Install the package https://github.com/sublimelsp/LSP
Configuration of the LSP:
{
"clients": {
"odin": {
"command": [
"/path/to/ols"
],
"enabled": false, // true for globally-enabled, but not required due to 'Enable In Project' command
"selector": "source.odin",
"initializationOptions": {
"collections": [
{
"name": "collection_a",
"path": "/path/to/collection_a"
}
],
"enable_semantic_tokens": true,
"enable_document_symbols": true,
"enable_hover": true,
"enable_snippets": true,
"enable_format": true,
}
}
}
}Install Coc.
Configuration of the LSP:
{
"languageserver": {
"odin": {
"command": "ols",
"filetypes": ["odin"],
"rootPatterns": ["ols.json"]
}
}
}Neovim has a builtin support for LSP.
There is a plugin that turns easier the setup, called nvim-lspconfig. You can install it with you prefered package manager.
A simple configuration to use with Odin would be like this:
local lspconfig = require('lspconfig')
lspconfig.ols.setup({});; With odin-mode (https://github.com/mattt-b/odin-mode) and lsp-mode already added to your init.el of course!.
(setq-default lsp-auto-guess-root t) ;; if you work with Projectile/project.el this will help find the ols.json file.
(defvar lsp-language-id-configuration '((odin-mode . "odin")))
(lsp-register-client
(make-lsp-client :new-connection (lsp-stdio-connection "/path/to/ols/executable")
:major-modes '(odin-mode)
:server-id 'ols
:multi-root t)) ;; This is just so lsp-mode sends the "workspaceFolders" param to the server.

Install the LSP plugin
Configure the plugin in micro's settings.json:
{
"lsp.server": "c=clangd,go=gopls,odin=ols"
}First, make sure you have the LSP plugin enabled. Then, you can find LSP settings for Kate in Settings -> Configure Kate -> LSP Client -> User Server Settings.
You may have to set the folders for your Odin home path directly, like in the following example:
{
"servers": {
"odin": {
"command": [
"ols"
],
"filetypes": [
"odin"
],
"url": "https://github.com/DanielGavin/ols",
"root": "%{Project:NativePath}",
"highlightingModeRegex": "^Odin$",
"initializationOptions": {
"collections": [
{
"name": "core",
"path": "/path/to/Odin/core"
},
{
"name": "vendor",
"path": "/path/to/Odin/vendor"
},
{
"name": "shared",
"path": "/path/to/Odin/shared"
},
{
"name": "src", // If your project has src-collection in root folder,
"path": "src" // this will add it as a collection
},
{
"name": "collection_a",
"path": "/path/to/collection_a"
}
],
"odin_command": "path/to/Odin",
"verbose": true,
"enable_document_symbols": true,
"enable_hover": true
}
}
}
}Kate can infer inlay hints on its own when enabled in LSP settings, so enabling it separately in the server config can cause some weird behavior.
