Some haphazard tools for cross-checking results between ICU4C and Babel. These are not meant to be production-ready or e.g. guaranteed to not leak memory in any way.

This worked on my macOS – on a Linux machine, you shouldn't need the PKG_CONFIG_PATH environment variable.

env PKG_CONFIG_PATH="/opt/homebrew/opt/icu4c@76/lib/pkgconfig" make bin/icu4c_date_format

E.g.

env TEST_TIMEZONES=Pacific/Honolulu TEST_LOCALES=en_US,en,en_GB TEST_TIME_FORMAT="YYYY-MM-dd H:mm zz" bin/icu4c_date_format
