Behdad Esfahbod 9385caa8a6 [test] Actually hook up hb_script_t tests
I really shall find a way to automate the test enumeration.  Otherwise
it's too easy to add a test and wrongly hook it up.  Did it twice today.

Behdad Esfahbod 07233581c9 Rename HB_TAG_STR() to HB_TAG_CHAR4()
The problem with HB_TAG_STR() was that it expected a string of size 4
exactly, and unlike hb_tag_from_string() it doesn't pad the tag with
space characters.  So, the new name is more appropriate.

Behdad Esfahbod 9faa980067 Add an in-tree test suite
Uses the glib testing framework.  Wrote unit tests for hb-common.h
types.

Behdad Esfahbod b13640de69 A few more ASSERTs 2011-04-11 12:29:31 -04:00
Behdad Esfahbod ae9eeaff93 Remove warning message from public header file
Since we now assert thos in hb-private.h, the int types cannot be wrong.
(Except for when someone else includes hb-common.h in a very broken
configuration, but that's not our problem!)

Plus, we don't use inline in the public headers, so remove that too.

Behdad Esfahbod a71b9c8579 Disable 'cswh' by default except for Arabic shaper
That better matches OpenType spec.  Note that we enable it for all
Arabic-shaper scripts.  Ie. we enable it by default for Syriac too,
but the SyriacOT spec does not require it.  I think this is a more
useful compromise than special-casing for Arabic script alone.

Behdad Esfahbod cab6f65bba [hb-view] setlocale (LC_ALL, "")
For now we don't use anything from the locale, but we should default
to using $LANG, etc, if --language is not specified.  Right?

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 ccc6745afa [hb-view] Use cached hb-ft face creation

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.
