Author	SHA1	Message	Date
Behdad Esfahbod	f4a579bc42	Add internal API for buffer var allocation	13 years ago
Behdad Esfahbod	651e8dd79e	Start cleaning up buffer var allocation ... I've messed up a lot of stuff recently, different parts of the shaping process are stumbling on eachother's toes because manually tracking what's in which buffer var is hard. I'm going to add some internal API to track those such that mistakes are discovered as soon as they are introduced.	13 years ago
Behdad Esfahbod	c86f932015	Move code around	13 years ago
Behdad Esfahbod	18c42850c9	Shrink space used for ligature ids ... This frees 16bits in the glyph_info struct during the ot_layout process. We can use the freed space in the shapers now.	13 years ago
Behdad Esfahbod	d8787493c9	Minor	13 years ago
Behdad Esfahbod	c311d85208	Keep Unicode props updated as we go so we avoid a scan later	13 years ago
Behdad Esfahbod	5389ff4dbc	Implement the Unicode Canonical Composition algorithm ... Fallback normalization is complete and working now!	13 years ago
Behdad Esfahbod	dcdc51cdc0	Handle singleton decompositions	13 years ago
Behdad Esfahbod	34c22f8168	Implement Unicode Canonical Reordering Algorithm	13 years ago
Behdad Esfahbod	4ff0d2d9df	Decomposition works now!	13 years ago
Behdad Esfahbod	468e9cb25c	Move buffer methods into the object	13 years ago
Behdad Esfahbod	45412523dc	More normalization kick	13 years ago
Behdad Esfahbod	63c0ef4a07	Fix decompose() implementations to work with non-starter non-composables ... Add tests.	13 years ago
Behdad Esfahbod	5d90a342e3	Document normalization design	13 years ago
Behdad Esfahbod	02cdf743c2	Add prefer_decomposed() complex-shaper callback ... This allows the Indic shaper to request decomposed characters. This will handle split matra for free. Other shapers prefer precomposed characters.	13 years ago
Behdad Esfahbod	d6b9c6d200	More kicking	13 years ago
Behdad Esfahbod	192445aef2	Remove intermittent_glyph() ... Lets not worry about performance for now...	13 years ago
Behdad Esfahbod	d63adfc7d0	No need to handle variation-selectors seperately, they are GC=Mn	13 years ago
Behdad Esfahbod	aa7264123a	Only form clusters if we are reversing ... This produces more accurate cluster mappings. Cluster mappings are minimal now. Combining marks get their own cluster value most of the time.	13 years ago
Behdad Esfahbod	5c6f5982d7	Towards normalization	13 years ago
Behdad Esfahbod	ad903e66b1	s/COMBINING_MARK/SPACING_MARK/ here too. Oops!	13 years ago
Behdad Esfahbod	cf7f43ec33	Remove stale comment	13 years ago
Behdad Esfahbod	54d1a0d2b2	Form clusters before ensuring native direciton ... This is essential as ensure_native_direction uses cluster info that is set by form_clusters().	13 years ago
Behdad Esfahbod	9111b21ef9	Add _hb_buffer_output_glyph() and _hb_buffer_skip_glyph()	13 years ago
Behdad Esfahbod	655586fe5e	Towards normalization	13 years ago

Behdad Esfahbod	dd89d958c1	Fix cluster calculation for non-LTR text	13 years ago
Behdad Esfahbod	4a68684654	When forming clusters, participate all mark types	13 years ago
Behdad Esfahbod	5157e12a55	Rename HB_UNICODE_GENERAL_CATEGORY_COMBINING_MARK to HB_UNICODE_GENERAL_CATEGORY_SPACING_MARK ... Spacing_Mark is the current Unicode long-name for this property value. The previous name was wrongly carried from glib.	13 years ago
Behdad Esfahbod	7b08b0a7f2	Minor	13 years ago
Behdad Esfahbod	498e1a9be6	[icu] Implement compose()/decompose()	13 years ago
Behdad Esfahbod	ffd4a436f7	Add tests for compose()/decompose() ... Adjust glib fallback implementation. The tests are not hooked up for ICU yet.	13 years ago
Behdad Esfahbod	fca0923b04	Minor	13 years ago
Behdad Esfahbod	26b6024962	[glib] Use g_unicode_script_to/from_iso15924() if available	13 years ago
Behdad Esfahbod	22fdc66712	[glib] Add compose() and decompose() implementations with fallback	13 years ago
Behdad Esfahbod	a54a5505a3	Minor	13 years ago
Behdad Esfahbod	23db8d5c92	[test] Work around glib <= 2.30 API	13 years ago
Behdad Esfahbod	22989c5ffc	Distribute hb-ot-shape-complex-indic-machine.rl	13 years ago
Behdad Esfahbod	f6fd3780e1	Let shapers decide when to apply ccmp and locl ... Instead of always applying those two features before the complex shaper, let the complex shaper decide whether they should be applied first. Also add stub for Indic's final_reordering().	13 years ago
Behdad Esfahbod	c4641723fb	[API] Add compose() and decompose() unicode funcs, rename other ones ... Add compose() and decompose() unicode funcs. These implement pair-wise canonical composition/decomposition. The glib/icu implementations are lacking for now. We are adding API for this to glib, but I cannot find any useful API in ICU. May end of implementing these in-house. Changed all unicode_funcs callback names to remove the "_get" part. Eg, hb_unicode_get_script_func_t is now hb_unicode_script_func_t, and hb_unicode_get_script() is hb_unicode_script() now.	13 years ago
Behdad Esfahbod	d05dded167	More code generation through preprocessor	13 years ago
Behdad Esfahbod	891c4755ba	Humm, undo some shuffling ... In preparation for adding more advanced unicode funcs.	13 years ago
Behdad Esfahbod	4b6317c4f4	More code shuffling	13 years ago
Behdad Esfahbod	3361c9a323	Minor	13 years ago
Behdad Esfahbod	76f76812ac	Shuffle code around, remove shape_plan from complex shapers	13 years ago
Behdad Esfahbod	e88bff9b4d	Minor, use function typedefs	13 years ago
Behdad Esfahbod	359dcaa0d3	Update copyright headers	13 years ago
Behdad Esfahbod	d8d0c480c8	Refactor some code common to GSUB and GPOS	13 years ago
Behdad Esfahbod	b70c96dbe4	Enable applying GSUB/GPOS features in multiple segments ... Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=644184 among others. Shapers now can request segmented feature application by calling add_gsub_pause() or add_gpos_pause(). They can also provide a callback to be called at the pause. Currently the Arabic shaper uses pauses to enforce certain feature application. The Indic shaper can use the same facility to pause and do reordering in the callback.	13 years ago
