2012-11-14 13:38:16 -08:00
Behdad Esfahbod dde5506fd9 [Indic] Don't move virama with left matra
This is important for the Sinhala U+0DDA split matra since it decomposes
to U+0DD9,U+0DCA where U+0DD9 is a left matra and U+0DCA is the virama.
We don't want to move the virama with the left matra.
TEST: U+0D9A,U+0DDA

Note that we were already doing this in the Uniscribe bug compatibility
mode.  We now do it all the time.

	HB_BUFFER_FLAG_BOT
	HB_BUFFER_FLAG_EOT
	HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES

	hb_buffer_set_flags()
	hb_buffer_get_flags()

We use the BOT flag to decide whether to insert dottedcircle if the
first char in the buffer is a combining mark.

The PRESERVE_DEFAULT_IGNORABLES flag prevents removal of characters like
ZWNJ/ZWJ/...

Behdad Esfahbod 0736915b8e [Indic] Decompose Sinhala split matras the way old HarfBuzz / Pango did

Uniscrie-style, but Jonathan and I convinced ourselves that there is no
harm doing this the Unicode way.  This change makes that happen, and
unbreaks free Sinhala fonts.

Behdad Esfahbod 9e92978c8a [Indic] Route "new" Myanmar tag through the Indic shaper
Windows 8 adds a Myanmar shaper using the 'mym2' tag.  Route that
through the Indic shaper.  It's still very broken, but at least this
does NOT break old-style Myanmar shaping using the generic shaper.

Behdad Esfahbod 5ab3855f81 Choose shaper based on chosen OT script tag

that one.

Behdad Esfahbod 6b389ddc36 [Indic] Don't apply 'liga'
Uniscribe doesn't.  And some fonts abuse this feature to get Indic

Behdad Esfahbod 0bc7a38463 [OT] Fix ReverseChainingSubst
We should make it clear that we don't want output buffer in this case,
otherwise buffer->backtrack_len() would be wrong.

Behdad Esfahbod 88d3c98e30 [Indic] Position pre-base reordering Ra after Chillus in Malayalam
The logic for pre-base reordering follows the left matra logic.
We had an exception for Malayalam/Tamil in the left matra repositioning
which was not reflected in pre-base reordering.

Malayalam failures down from 337 to 323.

Behdad Esfahbod 71ee1f2450 Port to ICU LayoutEngine C API
Incidentally, this makes it not crash with icu-le-hb anymore...
I'm not smart / stupid enough to spend two more days debugging C++
linking issues, and this is ABI-stable at least.

Behdad Esfahbod cf3afd8979 Rename and revamp is_zero_width() to be is_default_ignorable()
That's really the logic desired.  Except that MONGOLIAN VOWEL SEPARATOR
is not default_ignorable but it really should be.  Reported to Unicode.

Based on suggestion from Konstantin Ritt.

Now that we have pthread detection in configure, we don't need Glib
anymore.  Glib will only be a Unicode data provider.

If the first char in the run is a combining mark, but there is text
before the run, don't insert dottedcircle.

Behdad Esfahbod 05207a79e0 [buffer] Save pre/post textual context
To be used for a variety of purposes.  We save up to five characters
in each direction.  No public API changes, everything is taken care
of already.  All clients need to do is to call hb_buffer_add_utf* with
the full text + segment info (or at least some context) instead of
just passing in the segment.

Various operations (hb_buffer_reset, hb_buffer_set_length,
hb_buffer_add*) automatically reset the relevant contexts.

Behdad Esfahbod fab7a71f11 [Indic] Import ragel-generated Indic machine in git
I don't expect ragel to be creating too much noise in its generated
output, and including this in-tree helps users right now.  We can
revisit this later if it proved to be too much trouble.
