Mac App Store
The App Store listing is called Glassine Writer — the name “Glassine” alone was already reserved there. The app itself, its window, its icon and its files are all still Glassine. Glassine Writer on the Mac App Store — free; the store updates it. The store has version 0.2.3; what came after it in the direct download (the settings, sync with GitHub, the rule fix) follows in the next store build.Direct download
Glassine.dmg — notarized, signed with a Developer ID, so it opens without a warning. Open it and drag Glassine to Applications. Every version is under Releases on GitHub. The direct version updates itself: once a day it checks a feed at glassine.ink, and when there is a newer version it says so, downloads it, verifies its signature and installs it in place, relaunching into the new one. Help → Check for Updates… asks now; Settings → General turns the daily check off.Build from source
You need Xcode, free from the App Store. Its command-line tools are all the build uses; the Xcode app itself never has to open.1

Build and install
Glassine.app into /Applications, and opens it. If a copy is already running it is asked to quit first.3
Update later
./build.sh builds into build/Glassine.app without installing, ./build.sh --run builds and opens it from there, ./build.sh --debug compiles faster while you are changing the code, and ./build.sh --appstore builds the sandboxed App Store flavor locally. Opening Package.swift in Xcode and pressing Run works too and is handy for debugging, but the assembled app from build.sh is the one to use day to day: it has the icon and a stable identity for macOS permissions.
First launch
macOS asks whether Glassine may reach files in iCloud Drive; the prompt says what for — the Glassine folder, read to list your documents and written to as you type. Say yes; that is where the library lives. A Glassine folder appears at the top level of iCloud Drive with a welcome document inside it, and you are in the editor. The App Store version cannot read iCloud Drive directly, so it keeps its documents in an iCloud folder of its own. Finder shows that folder as Glassine in iCloud Drive as well, with the app’s icon. If you would rather it used the same folder as the direct version, or any other folder, point it there under Settings → General; the permission is remembered.If iCloud Drive is turned off on the Mac, documents stay local. Everything else works.
