Behdad Esfahbod 6bd9b479b8 Hide backend-specific shape functions
Also remove shaper_options argument to hb_shape_full().  That was
unused and for "future".  Let it go.

More shaper API coming in preparation for plan/planned API.

We need this to set data on objects safely without worrying that some

Behdad Esfahbod 3ca6c4ecc2 Change hb_shape() API back to what it was, add hb_shape_full()
I disliked changing hb_shape() API, and disliked the fact that it was
returning a bool now.  So, reverted.  Added new API for the extra
functionality.

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 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.

Behdad Esfahbod 1a64f6e19a [API] Add HB_LANGUAGE_INVALID 2011-05-13 22:55:32 -04:00
Behdad Esfahbod 34fb5521a5 [API] Add hb_language_get_default()
It uses locale information to detect default language.  It's used by
hb_shape() whenever language is not set on the buffer.

Not sure how to properly test it in the test suite.  Tested by observing
that with DejaVu Sans we select the proper local glyph version for U+431
under Serbian locale.  See http://www.pango.org/ScriptGallery

Behdad Esfahbod c57d454acc Rename all private sources and headers to C++ files
So we can liberally use the simple features of C++ that parts of the
codebase is already using.

Ryan Lortie 2fd0c577e3 [API] unicode: rework virtual functions for subclassing
Unicode data providers can now be subclassed, including support for
chain-up.  The interface should now be nicely bindable, as well.

Also fix glib unicode funcs that where broken after hb_script_t
changes.  Nicely caught by the test-unicode.c added in this commit.

Behdad Esfahbod 62879eebd9 [API] Use ISO 15924 tags for hb_script_t
This simplifies the code, reduces static data, and makes the design
more extensible to future additions of new scripts.

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.
