🔨 Odin Language Support for Zed

This project provides Odin programming language support, featuring syntax highlighting and code navigation via Tree-sitter, Language Server capabilities like autocompletion and diagnostics, and full debugging support.

Tree Sitter: tree-sitter-odin
Language Server: @DanielGavin/ols
Debug Adapters: LLDB (Built-in)

Language Server

This extension automatically updates to the latest OLS (Odin Language Server) monthly build on each startup.

Using a Custom OLS Binary

If you want to use a specific OLS version or a locally built binary, you can override the automatic download:

{
  "lsp": {
    "ols": {
      "binary": {
        "path": "/path/to/your/ols",
        "arguments": []
      }
    }
  }
}

Binary Resolution Order

The extension searches for the OLS binary in the following priority order:

Custom binary path - If configured in settings (see above)
System PATH - Checks if ols is available in your system PATH
Cached binary - Uses previously downloaded version if available
GitHub download - Downloads latest release from DanielGavin/ols

Configuration

Configure via Zed Settings (Recommended)

Add OLS configuration directly in your Zed settings.json. This approach works project-wide and doesn't require additional files:

{
  "lsp": {
    "ols": {
      "initialization_options": {
        "enable_hover": true,
        "enable_snippets": true,
        "enable_procedure_snippet": true,
        "enable_completion_matching": true,
        "enable_references": true,
        "enable_document_symbols": true,
        "enable_format": true,
        "enable_document_links": true,
        "collections": [
          {
            "name": "shared",
            "path": "/path/to/shared"
          }
        ]
      }
    }
  }
}

Use `ols.json` in Workspace Root

Alternatively, create an ols.json file at the root of your workspace.For more configuration options, see the OLS documentation.

Snippets

You can define custom code snippets to speed up your Odin development workflow.

Creating Snippets

Open the command palette (Cmd/Ctrl+Shift+P)
Run snippets: configure snippets
Create or edit odin.json in the snippets directory
Add your snippets in JSON format

Example snippet:

{
  "Main procedure": {
    "prefix": "main",
    "body": [
      "package main",
      "",
      "import \"core:fmt\"",
      "",
      "main :: proc() {",
      "\t$0",
      "}"
    ],
    "description": "Creates a main package with imports"
  }
}

For detailed information about creating and using snippets, see Zed's snippet documentation.

Debugging

This extension supports debugging Odin applications using LLDB.
