IUI Programming Language

IUI CLI

To run iui code, use a command like the following:

node iui one.iui

VSCode Extension

The VSCode extension supports syntax highlighting and adds a file icon to iui files.

Developing the Extension

• Open just the extension folder in VSCode.
• Use the VSCode launcher to open a VSCode window with the current version of the extension running.
• Use cmd + p to run Developer: reload window when making any changes.
• When making changes to the grammar, run node syntaxes/generate.js to generate the json.

Deploying the Extension

• Open just the extension folder in VSCode.
• Increment the semantic version number in package.json.
• Update vsce to the latest version with npm install --global @vscode/vsce
• Run vsce publish. This publishes to VSCode's marketplace.
• Run vsce package. This generates a .vsix file.
• Upload the .vsix file to https://open-vsx.org/ so it appears in Cursor. Click "Publish" and click "Publish Extension". Then select the .vsix file.

Runtime

Development

Any changes or new dependencies should be added to the compiler/generateRuntime.js script. After running that file with Node it will build an updated runtime/runtime.js file.
