Behdad Esfahbod 6843ce01be Add atomic-pointer functions
Gonig to use these for lock-free linked-lists, to be used for
hb_language_t among other things.

Behdad Esfahbod bf93b636c4 Remove constructor from hb_prealloced_array_t
This was causing all object types to be non-POD and have static
initializers.  We don't need that!

Now, most nil objects just moved from .bss to .data.  Fixing for that
coming soon.

Behdad Esfahbod 96a9ef0c9f Remove tab character like other "zero-width" characters
Uniscribe does that, this make comparing results to Uniscribe
easier.

Behdad Esfahbod 0558d55bac Remove hb_atomic_int_set/get()
We never use them in fact...

I'm just adjusting these as I better understand the requirements of
the code and the guarantees of each operation.

Behdad Esfahbod e4b6d503c5 Don't use atomic ops in hb_cache_t
We don't care about linearizability, so unprotected int read/write
are enough, no need for expensive memory barriers.  It's a cache,
that's all.

Behdad Esfahbod 303d5850ec Fix Windows atomic get/set
According to:
http://msdn.microsoft.com/en-us/library/65tt87y8.aspx

MemoryBarrier() is the right macro to protect these, not _ReadBarrier()
and/or _WriteBarrier().

The old code was doing nothing.

Still got to find an example font+string that makes this matter, but
need this for fixing synthetic GDEF anyway.

Behdad Esfahbod 5df809b655 [GSUB/GPOS] Remove context_length
The spec doesn't say contextual matching should be done this way,
and AOTS doesn't do it either.  It was inherited from old HarfBuzz.
Remove it.

Behdad Esfahbod 18c06e189b [Indic] Add Uniscribe bug feature for dotted circle
For dotted-circle independent clusters, Uniscribe does no Reph shaping
for the exact sequence Ra+Halant+25CC.  Which also is the only possible
sequence with 25CC at the end.

Behdad Esfahbod 8c0aa486f3 [Indic] Allow two Nuktas per consonant
Uniscribe allows up to two nuktas per consonant and one per matra. It does so

Behdad Esfahbod 5f131d3226 [GSUB/GPOS/Indic] Apply GSUB/GPOS within syllables only
This does not apply to the context matchings.

2012-05-10 18:34:34 +02:00
Behdad Esfahbod 8df5636968 [Indic] Reorder Reph to before the Halant after Matras
Uniscribe doesn't do it, but we want to do as it gives the Reph the
opportunity to interact with the Matras.  Test with mangal for example.
Sequence: <0930,094d,0915,094b,094d>
In test suite already.
2012-05-10 15:41:04 +02:00
Behdad Esfahbod daf3234bdc [Indic] Don't clear the mask for Reph
This was removing the mandatory global 1 bit in the mask and hence
disabling GPOS for Reph!

Behdad Esfahbod 7708ee23cb [Indic] Improve Left Matra repositioning

2012-05-10 14:48:25 +02:00
Behdad Esfahbod dbb105883c [Indic] Do Reph repositioning in final reordering like the spec says
This introduced a failure, which we tracked down to a test case like this:

  U+092E,U+094B,U+094D,U+0930

The final character is a Ra that should be put in a syllable of it's
own.  And we do.  But it will interact with the Halant before it.  So
now we finally are convinced that we have to limit features to syllable
boundaries.  That's coming after lunch!

Behdad Esfahbod 71632c96da Fallback to Latin script if the font has no other usable scripts
Patch and description from Jonathan Kew:

It turns out that some legacy Thai fonts provide OpenType substitution
features to implement mark positioning, but (incorrectly) put those
features/lookups under the 'latn' script tag instead of using 'thai' (or
possibly 'DFLT'). See
https://bugzilla.mozilla.org/show_bug.cgi?id=719366 for an example and
more detailed description.

Although this is really a font bug, I suggest that we could improve the
rendering of such fonts by looking for the 'latn' as a fallback if
neither the requested script nor "default" is found in
hb_ot_layout_table_choose_script. Suggested patch against harfbuzz
master is attached.

This does _not_ affect the other kind of legacy Thai font, where custom
code to support vendor-specific PUA codepoints would be needed. I'm not
keen to go down that path; IMO, such fonts should be ruthlessly stamped
out in favour of standards-based solutions. :)

In hb_ot_tag_from_language(), if first component of an unknown
language is three letters long, use it directly as OpenType language
tag (after case conversion and padding).

Behdad Esfahbod 290e3ee517 [graphite] Only pass the first part language tag to graphite
Still not sure about:

1) Case.  We pass lowercase for now.  Would be nice if graphite was
uppercase 3letter like OpenType,

2) Padding.  IMO, tag padding is always with spaces, but Martin was
talking about NUL bytes.
2011-08-26 09:25:04 +02:00
Behdad Esfahbod 4c9fe88d30 [API] Make all _from_string() functions take a len parameter
Can be -1 for NUL-terminated string.  This is useful for passing parts
of a larger string to a function without having to copy or modify the
string first.

Affected functions:

	hb_tag_t hb_tag_from_string()
	hb_direction_from_string()
	hb_language_from_string()
	hb_script_from_string()

Behdad Esfahbod 3007ffa9e5 Reorder combining-class to better suit Arabic shadda mark-mark positioning
As reported by Khaled on the list:

"After the introduction of canonical reordering of combining marks
(commit 34c22f8), I'm no longer able to do mark/mark substitution or
positioning for mark sequences that involve shadda as a first mark (or
most interesting sequences at least).

"After some digging, it turned out that shadda have a ccc=33 while most
Arabic marks that combine with it have a lower ccc value, which results
in the shadda being reordered after the other mark which,
unsurprisingly, breaks my contextual substitution and mkmk anchors."

Behdad Esfahbod e6c09cdf43 Remove the pre_allocate argument from hb_buffer_create()
For two reasons:

1. User can always call hb_buffer_pre_allocate() themselves, and

2. Now we do a pre_alloc in add_utfX anyway, so the total number of
reallocs is limited to a small number (~3) anyway.  This just makes the
API cleaner.

Remove hb_ft_get_font_funcs() as it cannot be used by the user anyway.

Add hb_ft_font_set_funcs().  Which will make the font internally use
FreeType.  That is, no need for the font to have created using the
hb-ft API.  Just create using hb_face_create()/hb_font_create() and
then call this on the font (after having set font scale).  This
internally creates an FT_Face and attached to the font.

2011-08-05 17:22:19 -04:00
Behdad Esfahbod 02aeca985b [API] Changes to main shape API
hb_shape() now accepts a shaper_options and a shaper_list argument.
Both can be set to NULL to emulate previous API.  And in most situations
they are expected to be set to NULL.

hb_shape() also returns a boolean for now.  If shaper_list is NULL, the
return value can be ignored.

shaper_options is ignored for now, but otherwise it should be a
NULL-terminated list of strings.

shaper_list is a NULL-terminated list of strings.  Currently recognized
strings are "ot" for native OpenType Layout implementation, "uniscribe"
for the Uniscribe backend, and "fallback" for the non-complex backend
(that will be implemented shortly).  The fallback backend never fails.

The env var HB_SHAPER_LIST is also parsed and honored.  It's a
colon-separated list of shaper names.  The fallback shaper is invoked if
none of the env-listed shapers succeed.

New API hb_buffer_guess_properties() added.

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.

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.

While the cluster fields of the glyph string are usually sorted, they

optimization we have to make sure we know the buffer clusters are
monotonic and in which direction.  Not sure it's worth it though.

Behdad Esfahbod da97541988 [API] Allow negative font x_scale/y_scale
I was reconsidering whether y should grow down, since all three/four
times I've used this API I was tricked and got that wrong in my use.
So I was very inclined to make y grow down instead of up.  However,
considering that the font space has y up and it would be very confusing
for callbacks to work against that, I decided that what I really want
is for the user to be able to set y_scale to a negative number to imply
that user-space y grows down.

Changing x_scale/y_scale from unsigned int to int allows that, and I've
made pango to use that instead of negating glyph y_offset later.  hb-ft
however still has y group up.  I *guess* that's how FreeType works?
I'm not sure, FreeType docs don't make this clear...

I'm happy with the resolution :-).

Behdad Esfahbod 9417c1c0d2 [API] Make hb_face_reference_table() return empty blob instead of NULL
The idea here is that:

  - Like pretty much all other API in harfbuzz, user does not have to
    check for NULL.

  - In any caller code, the case of missing table should be handled
    exactly the same way that a too-short table is handled.  Turning
    a non-existent talbe into a table of size 0 makes the user code
    safer.

Behdad Esfahbod fb9ca1bfab [hb-view] Rewrite --features parsing, with range support
The --features parsing handles errors now.  More importantly, it
allos limiting individual features to specific byte ranges.  The
format is Python-esque.  Here is how it all works:

  Syntax:	Value:	Start:	End:

Setting value:
  "kern"	1	0	∞	# Turn feature on
  "+kern"	1	0	∞	# Turn feature off
  "-kern"	0	0	∞	# Turn feature off
  "kern=0"	0	0	∞	# Turn feature off
  "kern=1"	1	0	∞	# Turn feature on
  "kern=2"	2	0	∞	# Choose 2nd alternate

Setting index:
  "kern[]"	1	0	∞	# Turn feature on
  "kern[:]"	1	0	∞	# Turn feature on
  "kern[5:]"	1	5	∞	# Turn feature on, partial
  "kern[:5]"	1	0	5	# Turn feature on, partial
  "kern[3:5]"	1	3	5	# Turn feature on, range
  "kern[3]"	1	3	3+1	# Turn feature on, single char

Mixing it all:

  "kern[3:5]=0"	1	3	5	# Turn feature off for range

Behdad Esfahbod b2da26d1e3 [hb-view] Support --features
Accepts values like:

  --features="-mkmk,aalt=2,calt=1,+cswh"

A minus sign means "=0", a plus sign means "=1".  Default is "=1".
A minus sign overrides an explicit value.

Behdad Esfahbod 5d91c3d547 Add script to/from ISO 15924 tag support
Also adds --script support to hb-view.

If a script tag is not known to us, we pass the ISO 15924 tag around.
Right now, the OT layer ignores that, but we can fix it to blindly
convert that to an OT script tag.

Behdad Esfahbod 3286fc0e9a Let hb_shape() guess script and direction...
- Rename HB_SCRIPT_INVALID_CODE to HB_SCRIPT_INVALID

- Add HB_DIRECTION_INVALID

- Make hb_script_get_horizontal_direction() public

- Make hb_shape() guess script from buffer text (first non-common
  non-inherit script) if buffer script is set to HB_SCRIPT_INVALID (this
  is NOT the default.)

- Make hb_shape() guess direction from buffer script if buffer direction
is set to HB_DIRECTION_INVALID (this is NOT the default.)

- Make hb-view.c set INVALID script and direction on the buffer.

The above changes are meant to make hb-view fairly useful for uni-script
uni-direction text.  The guessing behavior however is NOT the default of
hb_shape() and must be asked for explicitly.  This is intended, because
the guess is not a suitable substitute to full-fledged bidi and script
segmentation.  It's just a testing tool.

Behdad Esfahbod d86a5b3c57 Bug 32274 - classic mongolian shaper
Add support for classic Mongolian script to the Arabic shaper.

Still work to be done around U+180E MONGOLIAN VOWEL SEPARATOR as it
should not be included in the final glyph stream the same way that
ZWNJ, etc should not appear in the final glyph stream.

But the joining part should be done.

There remains the question of how should the U+18A9 MONGOLIAN LETTER ALI
GALI DAGALGA be handled as it has General Category NSM but a letter
nonetheless.  For now, our generic logic makes this a joining T instead
of joining D as other Mongolian letters are.
