Glyphium

A GPU-rendered terminal emulator in Rust, built on libghostty-vt.

Status: early development. Milestone 1 is closed: the desktop app builds and passes real-window end-to-end scripts, and the core passes fuzz tests. See docs/PROGRESS.md and docs/adr/0001-core.md.

Install with Homebrew

brew trust gitguy268/tap
brew install gitguy268/tap/glyphium

This builds Ghostty's terminal core and glyphium from source on macOS (a few minutes; Rust and Zig are fetched as build tools). Then run glyphium.

Run it locally, step by step

Install Rust and Zig, which builds the terminal core.

Get the code:

git clone https://github.com/Gitguy268/glyphium.git
cd glyphium

Build the terminal core from Ghostty:

git clone https://github.com/ghostty-org/ghostty.git .tools/ghostty
git -C .tools/ghostty checkout cec8b92
(cd .tools/ghostty && zig build -Demit-lib-vt -Doptimize=ReleaseFast)

Build and start the desktop app:
```
cargo run --release -p glyphium
```
Quit by closing the window. The first build takes several minutes.
