GitHub Tray

A native macOS menu bar app that keeps your GitHub pull requests visible at a glance.

GitHub Tray shows PRs in focused sections and lets you jump straight to each PR from the menu bar.

What It Does

• Shows Review Requested PRs in your menu bar.
• Splits your authored PRs into:
  • Awaiting Reviewer
  • Approved
  • Returned to You
  • My Open PRs (everything else)
• Shows PRs where you are Mentioned In.
• Displays per-PR status indicators for checks (pending, success, failure).
• Supports optional launch-at-login (Autostart).

Tech Stack

• Rust core (github-tray-core) for GitHub API access and app state.
• UniFFI for Rust Swift bindings.
• Swift/AppKit macOS menu bar UI (SwiftApp).
• Tokio + Reqwest for async GitHub calls.

Prerequisites

• macOS
• Xcode + Xcode Command Line Tools
• Rust (stable)
• just
• xcodegen

Install helpers:

cargo install just
brew install xcodegen

Configuration

Create config file:

just setup-config

This creates:

• ~/Library/Application Support/github-tray/config.toml

Example:

github_token = "ghp_xxx"
refresh_interval_secs = 300
autostart = true

Token notes:

• Use a GitHub Personal Access Token.
• repo scope is required for private repositories.

Build & Run

First time

just gen-xcode
just fresh

Day-to-day

just run

Build only

just build-app

App bundle output:

• SwiftApp/build/Build/Products/Release/GitHubTray.app

Development Commands

just check       # cargo check
just test        # cargo test
just lint        # cargo clippy -- -D warnings
just fmt         # cargo fmt
just ci          # fmt-check + lint + test + check

Useful:

just clean       # clear Rust + Xcode build artifacts
just rebuild     # clean + build app
just open-bundle # open existing built app

How It Works

1. Swift app starts GitHubTrayCore (Rust).
2. Rust loads config from ~/Library/Application Support/github-tray/config.toml.
3. Rust fetches PRs from GitHub GraphQL API on an interval.
4. Rust sends AppState updates via UniFFI callback trait.
5. Swift rebuilds the menu UI from the latest state.

Troubleshooting

“Config file not found”

Run:

just setup-config

“Failed to parse config” or token errors

Verify github_token is set and not placeholder text.

Xcode project missing

Run:

just gen-xcode

Swift/UI not reflecting Rust changes

Run a full rebuild:

just rebuild

Open app manually

open SwiftApp/build/Build/Products/Release/GitHubTray.app
