CALPUFF INP Syntax Highlighter

This extension provides syntax highlighting for CALPUFF .inp files using a custom TextMate grammar.

Features

• Highlights lines of the form ! VARIABLE = VALUE ! in different colors (variable vs. value).
• Treats lines starting with ! as comments.

Installation

1. Install Node.js, then run npm install -g vsce.
2. In this folder, run vsce package.
3. In VS Code, go to Extensions → “Install from VSIX...” → select the generated .vsix.
4. Open any .inp file to see the highlighting.

Configuration

To customize the highlighting colors, add this to your user settings.json:
