|
|
Saturday, August 13, 2014
|
|
|
|
=====================================
|
|
|
|
|
|
|
|
- Fix major shape-plan caching bug when more than one shaper were
|
|
|
|
provided to hb_shape_full() (as exercised by XeTeX).
|
|
|
|
http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1246370.html
|
|
|
|
- Fix Arabic fallback shaping regression. This was broken in 0.9.32.
|
|
|
|
- Major hb-coretext fixes. That backend is complete now, including
|
|
|
|
respecing buffer direction and language, down to vertical writing.
|
|
|
|
- Build fixes for Windows CE. Should build fine now.
|
|
|
|
- Misc fixes:
|
|
|
|
Use atexit() only if it's safe to call from shared library
|
|
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=82246
|
|
|
|
Mandaic had errors in its Unicode Joining_Type
|
|
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=82306
|
|
|
|
- API changes:
|
|
|
|
|
|
|
|
* hb_buffer_clear_contents() does not reset buffer flags now.
|
|
|
|
|
|
|
|
After 763e5466c0a03a7c27020e1e2598e488612529a7, one doesn't
|
|
|
|
need to set flags for different pieces of text. The flags now
|
|
|
|
are something the client sets up once, depending on how it
|
|
|
|
actually uses the buffer. As such, don't clear it in
|
|
|
|
clear_contents().
|
|
|
|
|
|
|
|
I don't expect any changes to be needed to any existing client.

Overview of changes leading to 0.9.34
|
|
|
|
Saturday, August 2, 2014
|
|
|
|
=====================================
|
|
|
|
|
|
|
|
- hb_feature_from_string() now accepts CSS font-feature-settings format.
|
|
|
|
- As a result, hb-shape / hb-view --features also accept CSS-style strings.
|
|
|
|
Eg, "'liga' off" is accepted now.
|
|
|
|
- Add old-spec Myanmar shaper:
|
|
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=81775
|
|
|
|
- Don't apply 'calt' in Hangul shaper.
|
|
|
|
- Fix mark advance zeroing for Hebrew shaper:
|
|
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=76767
|
|
|
|
- Implement Windows-1256 custom Arabic shaping. Only built on Windows,
|
|
|
|
and requires help from get_glyph(). Used by Firefox.
|
|
|
|
https://bugzilla.mozilla.org/show_bug.cgi?id=1045139
|
|
|
|
- Disable 'liga' in vertical text.
|
|
|
|
- Build fixes.
|
|
|
|
- API changes:
|
|
|
|
|
|
|
|
* Make HB_BUFFER_FLAG_BOT/EOT easier to use.
|
|
|
|
|
|
|
|
Previously, we expected users to provide BOT/EOT flags when the
|
|
|
|
text *segment* was at paragraph boundaries. This meant that for
|
|
|
|
clients that provide full paragraph to HarfBuzz (eg. Pango), they
|
|
|
|
had code like this:
|
|
|
|
|
|
|
|
hb_buffer_set_flags (hb_buffer,
|
|
|
|
(item_offset == 0 ? HB_BUFFER_FLAG_BOT : 0) |
|
|
|
|
(item_offset + item_length == paragraph_length ?
|
|
|
|
HB_BUFFER_FLAG_EOT : 0));
|
|
|
|
|
|
|
|
hb_buffer_add_utf8 (hb_buffer,
|
|
|
|
paragraph_text, paragraph_length,
|
|
|
|
item_offset, item_length);
|
|
|
|
|
|
|
|
After this change such clients can simply say:
|
|
|
|
|
|
|
|
hb_buffer_set_flags (hb_buffer,
|
|
|
|
HB_BUFFER_FLAG_BOT | HB_BUFFER_FLAG_EOT);
|
|
|
|
|
|
|
|
hb_buffer_add_utf8 (hb_buffer,
|
|
|
|
paragraph_text, paragraph_length,
|
|
|
|
item_offset, item_length);
|
|
|
|
|
|
|
|
Ie, HarfBuzz itself checks whether the segment is at the beginning/end
|
|
|
|
of the paragraph. Clients that only pass item-at-a-time to HarfBuzz
|
|
|
|
continue not setting any flags whatsoever.
|
|
|
|
|
|
|
|
Another way to put it is: if there's pre-context text in the buffer,
|
|
|
|
HarfBuzz ignores the BOT flag. If there's post-context, it ignores
|
|
|
|
EOT flag.

Thursday, July 17, 2014
|
|
|
|
=====================================
|
|
|
|
|
|
|
|
- Apply Arabic shaping features in spec order exactly.
|
|
|

Overview of changes leading to 0.9.31
|
|
|
|
Wednesday, July 16, 2014
|
|
|
|
=====================================
|
|
|
|
|
|
|
|
- Only accept valid UTF-8/16/32; we missed many cases before.
|
|
|
|
- Better shaping of invalid UTF-8/16/32. Falls back to
|
|
|
|
U+FFFD REPLACEMENT CHARACTER now.
|
|
|
|
- With all changes in this release, the buffer will contain fully
|
|
|
|
valid Unicode after hb_buffer_add_utf8/16/32 no matter how
|
|
|
|
broken the input is. This can be overriden though. See below.
|
|
|
|
- Fix Mongolian Variation Selectors for fonts without GDEF.
|
|
|
|
- Fix minor invalid buffer access.
|
|
|
|
- Accept zh-Hant and zh-Hans language tags. hb_ot_tag_to_language()
|
|
|
|
now uses these instead of private tags.
|
|
|
|
- Build fixes.
|
|
|
|
- New API:
|
|
|
|
* hb_buffer_add_codepoints(). This does what hb_buffer_add_utf32()
|
|
|
|
used to do, ie. no validity check on the input at all. add_utf32
|
|
|
|
now replaces invalid Unicode codepoints with the replacement
|
|
|
|
character (see below).
|
|
|
|
* hb_buffer_set_replacement_codepoint()
|
|
|
|
* hb_buffer_get_replacement_codepoint()
|
|
|
|
Previously, in hb_buffer_add_utf8 and hb_buffer_add_utf16, when
|
|
|
|
we detected broken input, we replaced that with (hb_codepoint_t)-1.
|
|
|
|
This has changed to use U+FFFD now, but can be changed using these
|
|
|
|
new API.

|
|
|
|
- Added gobject-introspection boilerplate. Nothing useful
|
|
|

right now. Work in progress. Gets enabled automatically if

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

|
|

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.
