benchmark-harf

This builds one benchmark-harf executable containing the shaping benchmark twice: once against HarfBuzz's <hb.h> API and once against HarfRust's <hr-hb.h> compatibility API. The HarfBuzz compilation registers its native OpenType shaper and, when available, its built-in HarfRust shaper. The output suffixes are:

• hb: HarfBuzz's native OpenType shaper
• hr: HarfRust through its C API
• hb-hr: HarfRust through HarfBuzz's shaper integration

The default paths expect release builds in ~/hb/build and ~/hr/target/release. Configure and build with:

meson setup build
meson compile -C build

Run the default workload corpus with:

./build/benchmark-harf

As with HarfBuzz's perf/benchmark-shape, custom inputs are font/text pairs:

./build/benchmark-harf font.ttf text.txt \
  --benchmark_min_time=.1s --benchmark_repetitions=5

The HarfBuzz, HarfBuzz build, HarfRust, and HarfRust build paths can be overridden at setup time:

meson setup build \
  -Dhb_root=/path/to/harfbuzz \
  -Dhb_build=/path/to/harfbuzz/build \
  -Dhr_root=/path/to/harfrust \
  -Dhr_build=/path/to/harfrust/target/release
