I built a simple tool called Lumina to solve a personal annoyance: I wanted Fish-style command suggestions in my terminal without switching my entire shell environment or dealing with heavy configurations.
What it does
Lumina acts as a wrapper for your existing shell. It records your command history into a local JSON file and provides inline ghost text suggestions based on that history as you type.
Key Features
- History-based Autocomplete: Suggestions are pulled directly from your persistent JSON storage.
- Built-in Validation: If you try to run a command that doesn't exist, it lets you know (with a bit of personality).
-
Lightweight: Built with Python and
prompt_toolkit. - Portable: Easy to install and runs on top of your current system shell.
I originally built this just for my own workflow, but I’ve open-sourced it in case anyone else finds it useful or wants to build upon it.
