# Run the Windows test suites under Wine (x86_64-pc-windows-gnu + mingw-w64).
#
# Usage: scripts/windows-wine-test.sh [cargo test args, default: the core crates]
#
# First run builds expat + FreeType + fontconfig for mingw into
# target/wine-deps/prefix (like Ghostty, from source; needs network for the
# expat tarball unless EXPAT_TARBALL points at one, and the fontconfig source
# from the zig package cache or FONTCONFIG_SRC). A dedicated WINEPREFIX lives in
# target/wine-prefix. Headless: no display is needed for console tests.
# See docs/rewrite/notes/windows-wine.md.
