Install

Orgstar is built from source; there are no prebuilt downloads yet.

Requirements

• macOS 26 or later.
• Xcode 27 (the Swift 6.2 toolchain).
• Optional: GNU Emacs, for the features that hand work to it on the Mac (Emacs Lisp code blocks that need full Emacs, Lisp table formulas the built-in interpreter can't run, and export to PDF, LaTeX, ODT and other formats). See Working alongside Emacs and other tools.

The Mac app

git clone https://gitbay.org/krz/orgstar.git
cd orgstar
scripts/build-app.sh
open .build/app/Orgstar.app

scripts/build-app.sh builds a release binary and assembles .build/app/Orgstar.app with its Quick Look and Spotlight extensions, signed ad hoc for use on your own Mac. Move it to /Applications to keep it. Pass a version number as the first argument to stamp the bundle (scripts/build-app.sh 1.0.0); the default is 0.1.0.

Once the app has been launched, Finder opens .org files with it, Quick Look shows them formatted, and Spotlight indexes their headings and text.

The iOS app

The iOS app (iOS 26 or later) currently builds for the Simulator:

scripts/build-ios-app.sh
xcrun simctl install booted .build/ios-app/Orgstar.app

See iPhone and iPad for what it does.

Updating

Pull and build again:

git pull
scripts/build-app.sh

Your settings live in ~/.config/orgstar/ and survive rebuilds.

Uninstalling

Delete Orgstar.app. To remove your settings as well, delete ~/.config/orgstar/. Your org files are never stored inside the app.
