rl-lang - VS Code
Full language support for rl-lang, a statically typed interpreted language built in Rust: syntax highlighting, diagnostics/hover via the language server, and commands to run, check, and scaffold projects - all in one extension.
Features
- Syntax highlighting - keywords, operators, literals, strings, and comments, via a TextMate grammar that works with any theme
- Language server - real-time diagnostics for type errors, undefined variables, and syntax errors, plus hover information for identifiers
- Commands:
rl: Run File - run the current .rl file with rl runrl: Check File - type-check the current file with rl checkrl: Dev (run project) - run the current project with rl dev (requires an rl.toml in the workspace root)rl: New Project - scaffold a new project with rl newrl: Restart Language Server - restart the LSP client without reloading the window
Usage
Install the extension and open any .rl file. Highlighting and the language server activate automatically. Run, check, and dev buttons appear in the editor title bar, and are also available by right-clicking a .rl file in the Explorer sidebar.
To create a new project, open the command palette (Ctrl+Shift+P) and run rl: New Project, then enter a name. The extension will offer to open the new folder automatically.
All command output goes to the rl-lang Output Channel at the bottom of the editor.
If VS Code doesn't detect the language, select RL from the language picker in the bottom status bar.
Example
dec int x = 10
dec string name = "rl-lang"
fn greet(string name) {
println("Hello, ", name)
}
greet(name)
Requirements
No separate installation needed. The rl binary is bundled with the extension for Linux and Windows (x86_64).
