🚀 How to Run

Clone the repo and open it in Xcode. You can build and run the app on macOS 14+.

git clone https://git.24unix.net/tracer/iKeyMon
cd iKeyMon
open iKeyMon.xcodeproj

Local release build

Use the helper script to produce distributables in dist/:

./scripts/build_release.sh

It cleans previous artifacts, builds the Release configuration, and drops both iKeyMon-<version>.zip and iKeyMon-<version>.dmg into the dist folder (ignored by git). To enable codesigning + notarization, copy signing.env.example to .signing.env, fill in your Developer ID identity, Apple ID, team ID, and app-specific password. The script sources that file locally (it remains gitignored) and performs signing/notarization when the values are present.

To auto-publish the artifacts as a Gitea release, extend .signing.env with:

GITEA_TOKEN="..."
GITEA_OWNER="tracer"
GITEA_REPO="iKeyMon"
# optional: GITEA_API_BASE="https://git.24unix.net/api/v1"
# optional: GITEA_TARGET_COMMIT="master"
# optional: GITEA_PRERELEASE="false"   # defaults to true until preferences are done
# optional Sparkle feed helpers:
# SPARKLE_EDDSA_KEY_FILE="$HOME/.config/Sparkle/iKeyMon.key"
# SPARKLE_DOWNLOAD_BASE_URL="https://git.24unix.net/tracer/iKeyMon/releases/download"
# SPARKLE_DOWNLOAD_VERSION_PREFIX="v"   # optional
# SPARKLE_APPCAST_OUTPUT="$ROOT_DIR/Sparkle/appcast.xml"  # default

GITEA_TARGET_COMMIT defaults to the current HEAD commit, so overriding it lets you publish from another branch if needed. Whenever those variables are set, the script will create (or reuse) tag v<version> and upload both ZIP and DMG as release assets automatically.

If you re-run the release script for the same version, it removes any existing assets with the same filenames before uploading, so you never end up with duplicate ZIP/DMG files on the release page.

Sparkle updates

iKeyMon uses Sparkle for macOS-safe updates.

Generate an EdDSA key pair once (./Packages/Sparkle/bin/generate_keys). Store the private key on-disk (for example ~/.config/Sparkle/iKeyMon.key, which the build script expects) and copy the public key into the SUPublicEDKey entry (see Info.plist notes below).
./scripts/build_release.sh signs the ZIP with Sparkle’s sign_update tool and invokes generate_appcast automatically when the Sparkle variables are present. The generated feed is written to Sparkle/appcast.xml, so commit that file after every release. Set SPARKLE_DOWNLOAD_BASE_URL to your release-download root (e.g. https://git.24unix.net/tracer/iKeyMon/releases/download) and, if your host groups assets under versioned folders, set SPARKLE_DOWNLOAD_VERSION_PREFIX (defaults to v, producing URLs like /download/v26.0.20/...). The feed stays inside the repo (it is not uploaded as a release asset).
Set SUFeedURL in Info.plist (or the corresponding build setting) to the raw URL of Sparkle/appcast.xml inside this repo (e.g. https://git.24unix.net/tracer/iKeyMon/raw/branch/master/Sparkle/appcast.xml).

Preferences expose Sparkle’s built-in toggles for “Automatically check” and “Automatically download”, and the toolbar button simply calls Sparkle’s “Check for Updates…” sheet.

./scripts/build_release.sh will call generate_appcast for you when SPARKLE_EDDSA_KEY_FILE and either SPARKLE_DOWNLOAD_BASE_URL (optionally with SPARKLE_DOWNLOAD_VERSION_PREFIX) or SPARKLE_DOWNLOAD_BASE_TEMPLATE are set. It tries to locate Sparkle’s CLI in DerivedData automatically, but you can override the path via SPARKLE_GENERATE_APPCAST. The resulting feed is written to SPARKLE_APPCAST_OUTPUT (defaults to Sparkle/appcast.xml).

Build settings include INFOPLIST_KEY_SUFeedURL and INFOPLIST_KEY_SUPublicEDKey. Make sure to fill both before shipping a build so Sparkle knows where to fetch updates and how to verify them.

Automated release push

If you want git push origin master to build/sign/notarize/upload automatically, enable the provided pre-push hook:

git config core.hooksPath hooks

The hook (see hooks/pre-push) watches for pushes that include refs/heads/master, automatically bumps marketing_version (incrementing the last component), runs scripts/build_release.sh, stages version.json, iKeyMon.xcodeproj/project.pbxproj, and Sparkle/appcast.xml, then creates a commit chore: release <version>. It performs its own git push behind the scenes and cancels the original push command so you don't upload the same refs twice—once you see “Release … pushed. Original push cancelled”, you're done (Git will report the original push failed; that's expected). To skip the automation temporarily, prepend SKIP_RELEASE=1 to your git push command.

The bumping logic lives in scripts/bump_version.sh (feel free to run it manually if you need to create a release without pushing).

Versioning workflow

The canonical marketing version lives in version.json and follows the format YY.major.minor (example: 26.1.2). Update that file manually whenever you cut a new release branch.
The build number is derived automatically from the git commit count on the current branch (you can override it by exporting BUILD_NUMBER before running the script if needed).
Run ./scripts/sync_version.sh anytime after editing version.json (the release script already calls it). The helper updates MARKETING_VERSION and CURRENT_PROJECT_VERSION inside iKeyMon.xcodeproj, keeping Xcode, the app bundle, and release artifacts in sync.
scripts/build_release.sh reads the same version.json for naming the generated ZIP/DMG, so the artifact names, Info.plist values, and UI displays all stay aligned.

📦 License

MIT — see LICENSE for details.

You're free to build and use this app however you want, but please don't upload an unchanged version to the App Store under the same name. Once it's stable, I may release it on the App Store for a small fee (1–2€) to cover my Apple Developer account.
