Jinja Modelica

Syntax highlighting for Jinja2 templates that generate Modelica code.

Features

Layers Jinja2 delimiter highlighting on top of Modelica syntax:

• {{ ... }} — variable expressions
• {% ... %} — tags / control flow
• {# ... #} — comments

Supported File Extensions

Prerequisites

This extension depends on an external Modelica grammar for the embedded Modelica highlighting. Install one of:

• SimplyDanny.modelica
• JamesGoppert.rumoca-modelica

If neither is installed, Jinja2 delimiters will still be highlighted — only the Modelica tokens outside them won't be colored.

Python syntax (used for Jinja2 expression content) is provided by VS Code's built-in Python extension.

Development

Run locally (no build step)

1. Open this repo in VS Code: code .
2. Press F5 (or Fn+F5 on Mac) — launches an Extension Development Host window with the extension loaded from source
3. Open any .mo.jinja2 file in that window to test highlighting

To iterate: edit the grammar in syntaxes/jinja-modelica.tmLanguage.json, then in the dev host window run Ctrl+Shift+P → Developer: Reload Window.

Inspect token scopes

Place the cursor on any token and run Ctrl+Shift+P → Developer: Inspect Editor Tokens and Scopes to verify which TextMate scopes are applied.

Build a .vsix for local install

npm install
npm run package
code --install-extension jinja-modelica-0.1.0.vsix

Manual File Association

If VS Code doesn't automatically recognize your files, add this to your settings.json:

{
  "files.associations": {
    "*.mo.jinja2": "jinja-modelica",
    "*.mo.j2": "jinja-modelica",
    "*.mo.jinja": "jinja-modelica"
  }
}
