Xojo Syntax Highlighting for VS Code

A lightweight syntax highlighting extension for the Xojo programming language.

Features

.xojo_window: Window → Controls → Events/Methods/Properties/MenuHandlers
- Hierarchical control layout based on InitialParent attribute
- Display child controls under container controls like DesktopTabPanel
- #tag Events blocks with hierarchical support (correctly associates events with nested controls)
.xojo_code: Class/Module/Interface/Structure/Enum → Methods/Properties/Events/Constants
- Automatically applies appropriate group structure for each object type
- Supports both #tag blocks and free-form declarations
.xojo_menu: Menu → DesktopMenuItem → (Submenu items)
- Recursively parses menu hierarchies
- Displays Text attribute as menu item details
- Special handling for separators (Text = "-")
Generic code files: Flat list of Sub/Function/Method/Event/Delegate declarations

Open this folder in VS Code
Start debugging the extension from Run and Debug (F5)
In the new VS Code window, open .xojo_code / .xojo_script files to verify syntax highlighting

To use the extension in normal mode without debugging, create and install a VSIX package.

With Node.js installed, you can create the package with npx. Run from the project root:

cd vscode_xojo_syntax
npx @vscode/vsce package

On success, xojo-syntax-<version>.vsix will be generated in the project root.

From VS Code Command Palette → "Extensions: Install from VSIX…" and select the .vsix file
Or from CLI:

code --install-extension xojo-syntax-0.1.0.vsix

To reinstall the same version, add --force:

code --install-extension xojo-syntax-0.1.0.vsix --force

Increment the version in package.json before repackaging to allow updates without --force.
If you plan to publish to the Marketplace in the future, adjust .vscodeignore to include the README and other documentation (currently excluded).
