LEO: Auto-typing Tool for Teaching Coding

LEO is a teaching assistant for windows that auto-types code from a lesson plan.

📦 Installation

Quickest way to get LEO running is using the stable release.

Alternatively, you can install the dependencies in order:

1. Python 3.12.2
2. AutoHotkey v1.1.37.02
3. python_ahk – A Python wrapper for AutoHotkey

🔧 VS Code Setup (Optional)

If you don’t have a preferred code editor, I recommend VS Code It comes with advanced features that help experienced coders. These (may) interfere with LEO lesson plans. You can disable them by loading the VS Code settings provided in the settings folder.

How to Apply Settings:

1. Open VS Code.
2. Press Ctrl + Shift + P.
3. Search for “Open User Settings (JSON)”.
4. Paste the contents of the desired JSON file into the settings and save.

📝 Notes

• 🪟 Windows only.

• 💻 Most of the code is written in Python.

• ⚙️ Requires some understanding of AutoHotkey (AHK).

• ❗Current version of AHK (v1.1.37.02) is now deprecated (still works at the moment)

• To create a new installation binary, use InnoSetup. Open LEOinstaller.iss, press compile on the toolbar, and it will create an exe file in the Output folder.

• screen.ahk provides optional window management shortcuts:

• Ctrl + Shift + Space: Keep window on top.

• Ctrl + Shift + T: Toggle window transparency.

• kill.bat stops all AHK scripts (check system tray for active ones).
