Zed extension that adds Tonel Smalltalk support:

Language server integration for Tonel Smalltalk

Current features

Syntax highlighting for .st files
"Go to definition" for class names
"Find references" for class names

Language server

The language server (tonel-smalltalk-language-server) is automatically downloaded when the extension is installed — no manual setup or PATH configuration is required.

The extension resolves the language server in this order:

Use tonel-smalltalk-language-server from your PATH if present
Otherwise download the latest release from mumez/tonel-smalltalk-language-server automatically

Supported platforms and their expected release asset names:

tonel-smalltalk-language-server-aarch64-apple-darwin.tar.gz
tonel-smalltalk-language-server-x86_64-apple-darwin.tar.gz
tonel-smalltalk-language-server-aarch64-unknown-linux-gnu.tar.gz
tonel-smalltalk-language-server-x86_64-unknown-linux-gnu.tar.gz
tonel-smalltalk-language-server-aarch64-pc-windows-msvc.zip
tonel-smalltalk-language-server-x86_64-pc-windows-msvc.zip

macOS/Linux assets use .tar.gz; Windows assets use .zip.

If the asset for your platform is missing from the latest release, Zed will show an installation error.

Specifying the binary path explicitly

As an alternative to the automatic resolution above, you can point directly to a tonel-smalltalk-language-server binary in your Zed settings.json. Download a binary for your platform from the releases page and configure its path, for example on Windows:

{
  "lsp": {
    "tonel-smalltalk-language-server": {
      "binary": {
        "path": "C:\\Users\\someone\\bin\\tonel-smalltalk-language-server.exe",
        "arguments": [],
      },
    },
  }
}
