Most of the changes in this release were made by laurmaedje.

0.2.0 - 2020-07-25

Ported

  • All complex shapers.
  • Tables: CBDT, CFF, CFF2, HVAR, MVAR, OS/2, SVG, VORG, VVAR, avar, cmap, fvar, glyf, gvar, hhea, hmtx, post, sbix, vhea, vmtx.
  • hb_buffer_t
  • hb_script_t
  • hb_feature_t
  • hb_variation_t
  • hb_language_t
  • hb_font_t
  • hb-ot-metrics
  • Unicode functions and tables.
  • Buffer serialization.

Changed

  • Update to HarfBuzz 2.7.0
  • Rename Font::from_data into Font::from_slice.
  • Font is parsed via ttf-parser first. And if the parsing fails, the Font will not be created. harfbuzz allows malformed fonts.

Removed

  • hb_font_funcs_t. Only the embedded TrueType implementation is used.
  • hb_unicode_funcs_t. Only the embedded Unicode implementation is used.
  • Font::set_scale/hb_font_set_scale/--font-size. Shaping is always in font units now. This simplifies the code quite a lot.
  • Shaping plan caching.
  • Fallback shaper.
  • Unused hdmx table.

0.1.1 - 2020-07-04

Fixed

  • Compilation with an old XCode.

0.1.0 - 2020-07-04

At this point, this is just a simple Rust bindings to a stripped down harfbuzz.

Added

  • An absolute minimum Rust API.
  • harfbuzz's shaping test suite had been ported to Rust.

Changed

  • harfbuzz source code was reformatted using clang-format.

Removed

  • Subsetting. This is probably a bit controversial, but I want to port only the shaper for now. This is also removes around 7000 LOC.
  • Arabic fallback shaper. Since it requires subsetting.
  • Unused TrueType tables: BASE, COLR, CPAL, JSTF, MATH, STAT, bsln, fdsc, gasp, just, lcar, ltag, meta, name, opbd.
  • All external dependencies: coretext, directwrite, freetype, gdi, glib, gobject, graphite, icu, uniscribe. Embedded harfbuzz relies only on internal TrueType implementation.
  • Most of the non-shaping harfbuzz API.
