#!/usr/bin/env bash
# Produce a fully-wired macOS .app bundle for openpencil-desktop.
#
# `cargo-bundle` 0.10.0 ignores most of our `[package.metadata.bundle]`
# entries (CFBundleName / CFBundleIdentifier / CFBundleIconFile come
# out blank or set to the package name, Resources/ is never created,
# and the UTI-based file-association keys aren't emitted at all). On
# macOS 10.10+ the document-binding lookup is UTI-based (.fig files
# are tagged `com.figma.document`), so without `LSItemContentTypes` +
# an `UTImportedTypeDeclarations` claim the OS will not route .fig
# double-clicks to our bundle even if `CFBundleTypeExtensions`
# contains "fig".
#
# This script:
#   1. Builds the release binary.
#   2. Runs cargo-bundle.
#   3. Renames the produced `.app` to `OpenPencil.app`.
#   4. Backfills the Info.plist with CFBundleName / CFBundleIdentifier
#      / CFBundleIconFile / CFBundleShortVersionString /
#      CFBundleDocumentTypes (with UTI binding) /
#      UTImportedTypeDeclarations.
#   5. Copies the icon into Resources/.
#   6. Re-registers the bundle with LaunchServices so Finder picks up
#      the .fig binding.
#
# Idempotent: re-running on a refreshed binary overwrites the patched
# fields without compounding them (PlistBuddy `Set` replaces; `Add`
# would duplicate, so this script clears the entries it rewrites
# first).
