Behdad Esfahbod 2e7c716511 [buffer] Add an assert 
See if it helps debugging https://bugs.chromium.org/p/chromium/issues/detail?id=895117

David Corbett a03f5f4dfb Replace "ISO 639" with "BCP 47" 
`hb_language_from_string` accepts not only ISO 639 but also BCP 47. Not
all ISO 639 codes are valid BCP 47 tags but the function does not accept
overlong language subtags anyway.

Behdad Esfahbod 14ebf8af0c [buffer] Improve shift_forward() 
"Improve" is a strong word in this case though, I understand.

Behdad Esfahbod 55bae6825e [docs] A few improvements 
If we wrote just this much every day...
 2018-09-24 10:43:06 -04:00
Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert() 
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

This reverts commit 94bfea0ce6.
This reverts commit 4e62627831.
 2018-09-16 19:34:39 +02:00
Behdad Esfahbod 4e62627831 Enforce single-param static_assert() only 
So we don't accidentally break it again.
 2018-09-16 18:09:36 +02:00
Behdad Esfahbod c77ae40852 Rename hb-*private.hh to hb-*.hh 
Sorry for the noise, downstream custom builders.  Please adjust.

Behdad Esfahbod f0ef096b8c Don't add reference in get_unicode_funcs() functions 
Users don't expect a new reference returned from a get() function.
Indeed, all users of that API I foud where NOT destroying the reference.
Just change the implementations to NOT return a reference.

This applies to the following APIs:
hb_unicode_funcs_get_default()
hb_glib_get_unicode_funcs()
hb_icu_get_unicode_funcs()

Towards possibly using Null pool for some nil objects.

Behdad Esfahbod f673cfbd64 Support scripts that are written both LTR and RTL 
Right now only Old Italic is marked as such.

Behdad Esfahbod cc1e0840ba [buffer] Tweak diff re glyph_flags again 
We expect the buffer to have no flags that the reference doesn't...
Meh. Makes MORX tests pass now. Need to better define the behavior.
 2018-02-06 10:20:48 -05:00
Ebrahim Byagowi d49ae5154e Fix hb-buffer logic error 2018-02-06 10:13:11 -05:00
Behdad Esfahbod 54e6efadd6 [aat] Fix unsafe-to-break 
At any position, if state is not zero, mark unsafe-to-break before,
unless we can reason it safe.

At any position, if there's an action entry for end-of-text, mark
unsafe to break.

Also changes buffer diff impl to allow for flag differences as long
as the buffer glyph flags are superset of reference glyph flags.

With this, all MORX tests pass.
 2018-02-04 17:18:54 -05:00
Behdad Esfahbod baf7779d2d Limit how much recursion GSUB/GPOS does 
This only counts recursions right now.  Good start.

Hopefully...

Behdad Esfahbod d03f11f246 Fix buffer_diff for empty buffers 
If buffers are empty, content type should be ignored.

This fixes last of the failing tests: fuzzed.tests.  Green again!

Behdad Esfahbod 099472e08b hb_buffer_diff() tweak 
I like to have a mode where CONTAINS_NOTDEF and CONTAINS_DOTTEDCIRCLE are not
returned.  Abused a value of -1 for that.  hb-shape now uses it.  Fixes two
of the six tests failing with --verify in test/shaping/run-tests.sh.

Emil A Eklund (eae) 91770e1c56 Fix signed/unsigned warning (#522) 
Change hb_buffer_diff to explicitly cast result of abs to unsigned when
comparing with position_fuzz to avoid unsafe signed/unsigned comparions
warnings on windows.

Jonathan Kew 331d66c7fe Add function to compare two buffers 
Based on patch from Jonathan Kew.

Needs more cleaning up and documentation.

New API:

hb_buffer_diff()

Behdad Esfahbod 05fabbd03e [unsafe-to-break] Towards verifying unsafe-to-break in --verify 
We break and shape fragments and reconstruct shape result from them.
Remains to compare to original buffer.  Going to add some buffer
comparison API and use here, instead of open-coding.

Behdad Esfahbod 1c17c2bde5 [unsafe-to-break] Copy flag to all glyphs in a cluster 
Makes consumption easier.
 2017-08-11 19:06:07 -07:00
Behdad Esfahbod ec104e5912 [unsafe-to-break] Mark unsafe is cluster merging is disabled 
We were relying on cluster merges not requiring unsafe flagging because
they get merged.  If cluster level requests no merging, then we flag
unsafe when merge would have happened.

Behdad Esfahbod 40bd7e9a1c [unsafe-to-break] Add UNSAFE_TO_BREAK flag

GSUB and Arabic shaper are updated.
GPOS and other shapers are NOT.
