GhosttyKit for Waycar

This repository publishes GhosttyKit.xcframework.zip, the libghostty terminal core from Ghostty that the Waycar iOS app links through Swift Package Manager. It is built without GNU gettext (libintl).

Upstream's Apple builds statically link GNU gettext, which is LGPL. Waycar does not need translated strings from the core, so this build turns internationalization off and leaves libintl out completely. Nothing else changes: the inputs are the ones the libghostty-spm 1.6.20260909 release used.

Compared with upstream's asset for the same Ghostty commit, every archive has the same headers and loses exactly 30 members, all of them gettext and gnulib objects. No slice has any gettext symbol, defined or referenced.

Use it from a package manifest:

.binaryTarget(
    name: "libghostty",
    url: "https://github.com/otreva/ghosttykit/releases/download/1.6.20260909-82938b6-nointl.1/GhosttyKit.xcframework.zip",
    checksum: "d64018c8fad48bf84a32622c653d33ef0d40ed154e2a760304924497b79c7de9"
)

Release names

Tags read <libghostty-spm release>-<Ghostty short commit>-nointl.<n>. For example, 1.6.20260909-82938b6-nointl.1 is the first build without gettext from libghostty-spm 1.6.20260909 and Ghostty 82938b6. n goes up when the same inputs are built again, for example with a newer Xcode. A rebuild always has a new checksum, because the zip records file times.

Rebuilding

You need macOS with Xcode, Zig 0.16.0, git and curl. Then run:

Scripts/build-libghostty.sh /path/to/work-dir

The script clones both projects at the pinned commits, adds the patch, and builds all slices, which takes about 30 minutes. It fails if a slice is missing or still contains gettext, and otherwise collects LICENSES/ and prints the zip's path and checksum.

Licenses

The core contains code from Ghostty, libghostty-spm and the libraries and fonts they build in. LICENSES/ has every license text, and LICENSES/README.txt lists each component. The release also attaches the same folder as LICENSES.zip. One component is copyleft: z2d (MPL-2.0). Its source is at https://deps.files.ghostty.org/z2d-7dbae85c81784dba9988320bf9543ed9a81350c8.tar.gz.
