Krypton

Keyboard-driven terminal emulator. Rust + Tauri v2, TypeScript + xterm.js.

One transparent native window. Terminals are DOM windows with custom chrome. Tiling workspaces, vim-style modes, and an ACP harness for running several coding agents side by side.

npm install
make dev       # run
make build     # bundle
make install   # macOS: /Applications + kryptonctl

Config: ~/.config/krypton/krypton.toml. Specs: docs/.

GitHub Releases

The release workflow runs when an annotated vX.Y.Z tag is pushed. It checks the version files and tests, builds signed and notarized macOS DMGs for Apple Silicon and Intel, builds four krypton-remote binaries, and publishes one GitHub Release after all assets pass verification. The DMG does not install kryptonctl, krypton-bridge, or the browser extension.

Before tagging, update package.json, package-lock.json, src-tauri/tauri.conf.json, src-tauri/Cargo.toml, and src-tauri/remote-runtime/Cargo.toml to the same X.Y.Z, then refresh src-tauri/Cargo.lock. Merge the release commit to master and run:

python3.12 scripts/verify-release.py version --tag vX.Y.Z
git fetch origin master
git tag -a vX.Y.Z origin/master -m "Release vX.Y.Z"
git push origin vX.Y.Z

The repository must have GitHub Actions secrets APPLE_CERTIFICATE (base64 Developer ID Application .p12), APPLE_CERTIFICATE_PASSWORD, KEYCHAIN_PASSWORD, APPLE_ID, APPLE_PASSWORD (Apple app-specific password), and APPLE_TEAM_ID. Missing signing or notarization credentials fail the build; the workflow does not publish an ad hoc build. Check the workflow run and the Release's DMGs, remote binaries, and SHA-256 files before announcing the version. See spec 295 for the release gates.
