Oyui: A modern TUI merge tool and staging interface for Jujutsu

[emilien-jegou]

Hey everyone,

I’ve been loving Jujutsu, but I found the built-in jj split-editing experience to be a
bit limited for reviewing commits.

So I built Oyui to replace it. You get the same core features with left/right inversion, partial staging and hunk sub-splitting, but now you also get:

• 🖥️ A Command Palette: For those annoying cases where you need bulk staging you can just run :add **/*rs.
• 🎨 40+ Built-in Themes: Catppuccin, Dracula, Gruvbox, Nord, Ayu...
• 🔧 Scriptable Config: The config uses Rune and supports
  hot-reloading so you can see theme or keybind changes live. e.g.:

pub fn config() {
  theme::set("quaoar");
  theme::bg::set("#000000");
  theme::file_staged_highlight::set(LineHighlightMode::Gradient(0.25));

  // You can nest config per view with on_mode:
  on_mode("file", || {
    // keybind can take modifiers: "ctrl", "shift" or "alt"
    keybind("ctrl-j", || view::file::cursor::down(5));
    keybind("ctrl-k", || view::file::cursor::up(5));
  });

  on_mode("tree", || {
    keybind("ctrl-j", || view::tree::cursor::down(5));
    keybind("ctrl-k", || view::tree::cursor::up(5));
  });
}

Installable via flakes, github releases or cargo:

cargo install oyui

I'd love feedback or feature requests, I have ideas going forward but they are mostly for my
own workflow! Ask yourself “what is the tool missing” and share.

Also would love to know what tools you are using right now for handling jj split.
