some content in. Enable using --enable-gtk-doc.
|
|
|
|
GObject and Introspection:
|
|
- Added harfbuzz-gobject library (hb-gobject.h) that has type
|
|
bindings for all HarfBuzz objects and enums. Enable using
|
|
--with-gobject.
|
|
- Added gobject-introspection boilerplate. Nothing useful
|
|
right now. Work in progress. Gets enabled automatically if
|
|
--with-gobject is used. Override with --disable-introspection.
|
|
|
|
OpenType shaper:
|
|
- Apply 'mark' in Myanmar shaper.
|
|
- Don't apply 'dlig' by default.

Overview of changes leading to 0.9.19
|
|
Tuesday, July 16, 2013

|

|
Overview of changes leading to 0.9.18
|
|
Tuesday, May 28, 2013
|
|
=====================================
|
|
|
|
New build system:
|
|
|
|
- All unneeded code is all disabled by default,
|
|
|
|
- Uniscribe and CoreText shapers can be enabled with their --with options,
|
|
|
|
- icu_le and old shapers cannot be enabled for now,
|
|
|
|
- glib, freetype, and cairo will be detected automatically.
|
|
They can be force on/off'ed with their --with options,
|
|
|
|
- icu and graphite2 are default off, can be enabled with their --with
|
|
options,
|
|
|
|
Moreover, ICU support is now build into a separate library:
|
|
libharfbuzz-icu.so, and a new harfbuzz-icu.pc is shipped for it.
|
|
Distros can enable ICU now without every application on earth
|
|
getting linked to via libharfbuzz.so.
|
|
|
|
For distros I recommend that they make sure they are building --with-glib
|
|
--with-freetype --with-cairo, --with-icu, and optionally --with-graphite2;
|
|
And package harfbuzz and harfbuzz-icu separately.
|
|
|
|

|
Arabic font, this release is over 3x faster than previous

Overview of changes leading to 0.9.13
|
|
Thursday, February 25, 2013
|
|
=====================================
|
|
|
|
- Build fixes.
|
|
- Ngapi HarfBuzz Hackfest in London (February 2013):
|
|
* Fixed all known Indic bugs,
|
|
* New Win8-style Myanmar shaper,
|
|
* New South-East Asian shaper for Tai Tham, Cham, and New Tai Lue,
|
|
* Smartly ignore Default_Ignorable characters (joiners, etc) wheb
|
|
matching GSUB/GPOS lookups,
|
|
* Fix 'Phags-Pa U+A872 shaping,
|
|
* Fix partial disabling of default-on features,
|
|
* Allow disabling of TrueType kerning.
|
|
- Fix possible crasher with broken fonts with overlapping tables.
|
|
- Removed generated files from git again. So, one needs ragel to
|
|
bootstrap from the git tree.
|
|
|
|
API changes:
|
|
- hb_shape() and related APIs now abort if buffer direction is
|
|
HB_DIRECTION_INVALID. Previously, hb_shape() was calling
|
|
hb_buffer_guess_segment_properties() on the buffer before
|
|
shaping. The heuristics in that function are fragile. If the
|
|
user really wants the old behvaior, they can call that function
|
|
right before calling hb_shape() to get the old behavior.
|
|
- hb_blob_create_sub_blob() always creates sub-blob with
|
|
HB_MEMORY_MODE_READONLY. See comments for the reason.
