.githooks/pre-push

 1#!/bin/sh
 2# Build the macOS binaries when a version tag is pushed.
 3#
 4# gitbay's runner is Linux and has no platform targeting, so the darwin tarballs
 5# cannot be built in CI. They are built here instead, on the Mac doing the push,
 6# and this is the better place for the gate: a build failure aborts the push, so
 7# a tag whose Mac binaries do not compile is never published. GitHub Actions
 8# found that out only after the tag was already public.
 9#
10# Uploading has to wait: `release asset add` needs the release, and the release is
11# created by the CI job this push triggers. So the upload is handed to a detached
12# helper that waits for the release to appear. Its log, and the tarballs, stay in
13# dist/macos/<tag>/ — rerun .githooks/upload-macos <tag> if it fails.
14#
15# Wired up with: git config core.hooksPath .githooks
