LeekScript for VS Code

Language support for LeekScript in Visual Studio Code: syntax highlighting, diagnostics, hover (inferred types), go to definition, find references, and more via the leekscript-lsp language server.

Requirements

• leekscript-lsp must be built and available on your PATH, or you must set its path in settings.

Build the LSP from the parsing workspace:

cd /path/to/parsing
cargo build -p leekscript-lsp
# Ensure target/debug/leekscript-lsp (or release) is on PATH, or set leekscript.server.path

Installation

Option A: Install from VSIX

1. Build the VSIX (from the leekscript-vscode folder):

   npm install && npm run compile && npx vsce package --no-dependencies
   

   This creates leekscript-0.1.0.vsix.

2. In VS Code:

   • Press Ctrl+Shift+P (Mac: Cmd+Shift+P) to open the Command Palette.
   • Run “Extensions: Install from VSIX…”.
   • Choose the leekscript-0.1.0.vsix file.
   • Reload the window if prompted.

   Alternatively, drag leekscript-0.1.0.vsix onto the Extensions sidebar.

Option B: Run from source (development)

1. Open the extension folder: File > Open Folder → select leekscript-vscode.
2. Press F5 to launch a new window with the extension loaded (Development Host).
3. Open a .leek file to activate; you should get diagnostics and hover if the LSP is running.

Settings

For local development, set a full path, for example:

{
  "leekscript.server.path": "/path/to/parsing/target/debug/leekscript-lsp"
}

Features

• Syntax highlighting for .leek files (keywords, strings, numbers, comments).
• Diagnostics from the language server (parse errors, type errors, deprecations).
• Hover showing inferred types for expressions and variables.
• Go to Definition (F12): jump to the definition of variables, functions, and classes.
• Find References (Shift+F12): list all references to the symbol under the cursor.
• Code Lens: reference count above functions, classes, and methods (e.g. “3 references”); click to run Find All References. Enable with leekscript.codeLens.references and ensure Editor: Code Lens is on.
