E++ Language Plus

This extension adds basic syntax highlighting for E++ files (.epp) in Visual Studio Code.

Install locally

1. Open the epp-vscode folder in VS Code.
2. Press F5 to launch a development extension host.
3. Open an .epp file in the new window and the syntax highlighting will apply.

Supported highlighting

• E++ keywords: function, with, do, end, if, then, else, while, return, print, input, text, endtext
• Operators: equals, plus, minus, times, divided, by, and, or, not
• Boolean constants: true, false
• Numbers, strings, comments, and punctuation

Debugging

This extension provides syntax highlighting and a simple Debug Adapter Protocol (DAP) debugger.

• Open the project root in VS Code.
• Use the launch configuration named E++: Launch current file in Run & Debug.
• Set breakpoints in .epp source and start the debugger.

You can still run the CLI debugger manually if needed:

./epp --debug path/to/file.epp

The DAP debugger supports source-level breakpoints, step/continue, and variable inspection.
