attyctl

A lightweight controller for handling the configurations of several terminal applications:

• macOS’s native Terminal
• Alacritty’s TOML settings (still a work in progress)
• WezTerm’s configuration (not yet)

This project forms a component of an evaluation of three alternatives, concentrating mainly on their energy usage to pinpoint the most eco‑friendly choice. 🍃

Its inception was a spur‑of‑the‑moment idea—I was looking for a simple, fast way to manage the terminal font.

Dependencies

• Use fzf to get an interactive, fuzzy‑search style font‑selection experience.
• Use system_profiler to retrieve a list of all installed font family names on macOS (see man system_profiler).

Setup

The setup step runs only when the ~/.local/fonts.txt file is missing, and you need to execute attyctl -setup each time you want to use newly installed fonts.

Alacritty support

Currently, testing has been limited to altering the [font.normal].family property.

I've created a tool that lets me adjust the font on the fly. Since I'm on a Mac, I use systemprofiler to generate a JSON list of all installed fonts, parse it for the family names, and cache that list in ~/.local/fonts.txt.
