Behdad Esfahbod 7aad53657e [config] Add HB_NO_OT_SHAPE / HB_NO_OT 
Part of https://github.com/harfbuzz/harfbuzz/issues/1652

Eric Muller 44a67ddeb8 Fix coding style. 2019-03-11 16:06:41 -07:00
Eric Muller 30d7c40f8c Add a flag to hb_buffer_t to prevent the insertion of dotted circles on incorrect character sequences. 
Current behavior unchanged if this flag is not set (and it isn't by default).

Behdad Esfahbod 35d410f2ba Remove ASSERT_POD 
Newer compilers / language allows structs with constructor in union.
So, this was not actually testing anything.  Indeed, the recent
change in DISALLOW_COPY *is* making some of our types non-POD.
That broke some bots.

Just remove this since it wasn't doing much, and I'd rather have
DISALLOW_COPY.

Behdad Esfahbod 39bd07aed5 Fix bunch of unused parameter warnings 
Show up with gcc -O0.

There's a few more but those are functions that need to be filled in.

Maybe this is a lost battle...

Behdad Esfahbod 00adf9c8a4 Minor 
Should be enough to get -hangul.cc out of SOURCES in Firefox build:
https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/moz.build

No one else should care!

Behdad Esfahbod e2b878055b Disable OTL processing for Hebrew if GPOS doesn't have Hebrew subtable 
New approach to fix this:
69f9fbc420

Previous approach was reverted as it was too broad.  See context:
https://github.com/behdad/harfbuzz/issues/347#issuecomment-267838368

With U+05E9,U+05B8,U+05C1,U+05DC and Arial Unicode, we now (correctly) disable
GDEF and GPOS, so we get results very close to Uniscribe, but slightly different
since our fallback position logic is not exactly the same:

Before:		[gid1166=3+991|gid1142=0+737|gid5798=0+1434]
After:		[gid1166=3+991|gid1142=0@402,-26+0|gid5798=0+1434]
Uniscribe:	[gid1166=3+991|gid1142=0@348,0+0|gid5798=0+1434]

Micro-test added.

Behdad Esfahbod 7627100f42 Mark unsigned integer literals with the u suffix 
Simplifies hb_in_range() calls as the type can be inferred.
The rest is obsessiveness, I admit.

Jonathan Kew 7244b3fc3b [hangul] Reorder Hangul tone mark to beginning of syllable, unless font implements it using a zero-width glyph. 2014-01-20 10:35:51 +00:00

Behdad Esfahbod 32478656ce [hangul] Tighten up character categories 
I had tried to expand to fill the blocks, but that sounds wrong in
retrospect.

Behdad Esfahbod 3d6ca0d32e [ot] Simplify normalization_preference again 
No shaper has more than one behavior re this, so no need for a callback.
 2013-12-31 16:35:37 +08:00
Behdad Esfahbod c98b7183f7 [ot] Add Hangul shaper 
Not exhaustively tested, but I think I got the intended logic
right.

The logic can perhaps be simplified.  Maybe we should disabled
normalization with this shaper.  Then again, for now focusing on
correctness.
