gr

A git history viewer in Rust and egui, based on gitk.

• src/lib.rs – UI-free core: history loading, graph layout, commit details and diffs, find, goto, history. Shells out to git.
• src/main.rs – the egui UI.
• fonts/ – Lyth Mono (SIL OFL), embedded and used where Menlo, loaded from macOS, is missing.
• themes/ – colour themes from iTerm2-Color-Schemes (MIT), in Ghostty's format; only those whose own licence is known and fits GPL-3.0-or-later, listed with licence and source in themes/licenses.yml and with each author's licence text in themes/NOTICES.md.
• vendor/winit/ – winit 0.30.13 (Apache-2.0), patched so the macOS press-and-hold accent menu works in text fields.

Run with cargo run --release -- [repo] [git log args] [-- paths], pinned to rustc 1.95 via rust-toolchain.toml.
