#
# build-parser.sh — Compile the Nova-compatible tree-sitter-zig parser.
#
# Purpose:
#   Build vendor/tree-sitter-zig/src/parser.c into a universal macOS dylib
#   that Nova loads via its private SyntaxKit framework.
#
# What it does:
#   - clang -dynamiclib for arm64 + x86_64
#   - links against Nova’s SyntaxKit framework (from /Applications/Nova.app)
#   - sets rpath @loader_path/../Frameworks so the dylib finds SyntaxKit
#     when Nova loads it from the bundled extension
#   - ad-hoc codesigns the dylib (Gatekeeper requirement)
#   - writes the result to Syntaxes/libtree-sitter-zig.dylib
#
# Usage:
#   ./Scripts/build-parser.sh
#
# Environment overrides:
#   NOVA_APP   Path to Nova.app (default: /Applications/Nova.app)
#   SDKROOT    macOS SDK path   (default: `xcrun --show-sdk-path`)
#
# Requirements:
#   macOS, Xcode Command Line Tools (clang + xcrun), Nova installed.
