Behdad Esfahbod f9edf16725 Add buffer serialization / deserialization API 
Two output formats for now: TEXT, and JSON.  For example:

  hb-shape --output-format=json

Deserialization API is added, but not implemented yet.

Behdad Esfahbod 407f80d625 [util] Add --bot / --eot / --preserve-default-ignorables 2012-11-13 15:33:27 -08:00
Behdad Esfahbod 321f73c16e [util] Add --text-before and --text-after to hb-shape / hb-view 
Use with Arabic, for example, to see the effect on joining.

Behdad Esfahbod 39b17837b4 Add hb_buffer_normalize_glyphs() and hb-shape --normalize-glyphs 
This reorders glyphs within the cluster to a nominal order.  This should
have no visible effect on the output, but helps with testing, for
getting the same hb-shape output for visually-equal glyphs for each
cluster.

Behdad Esfahbod c188548312 Add --verbose to hb-shape 
Just turns all --show-* options on.

Behdad Esfahbod 5db0683a82 [util] Make hb-shape continue shaping other lines if shapers failed 2012-06-02 12:13:08 -04:00
Behdad Esfahbod c87b317f0e [util] Add hb-ot-shape-closure tool 
Computes all the glyphs that may be generated given a font and
set of Unicode characters.

The order of the Unicode characters is irrelevant.

Sample output:

f f_f

behdad:util 0$ ./hb-ot-shape-closure Doulos\ SIL\ Regular.ttf i
i

Behdad Esfahbod 52e7b1424a [util] Make hb-view print out Unicode art if stdout is a terminal 2012-05-13 07:55:00 +02:00
Behdad Esfahbod 30874b4819 [util] Make tools default to stdin if no text is provided 
One less argument to type in typical testing workflow!

Behdad Esfahbod 2097951110 [util] Change default font size of hb-view to 256 
Most common usecase of hb-view is to test rendering of short words for
testing / inspection.  Not having to type "--font-size 150" each time
isn't such a bad idea...

Behdad Esfahbod 95cefdf96e Add --utf8-clusters 
Also fix cairo cluster generation.

Behdad Esfahbod 69b84a8f6c Fix hb-view surface size calc for vertical text 
For some reason it doesn't quite work with IranianNastaliq, but
that looks like a font issue.

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.

Behdad Esfahbod d530024168 [util] Make clusters work with char offset instead of UTF-8 offset 
This means the --features indices also refer to char position
instead of byte position now.  Same for cluster values reported
by hb-shape.

Will add an option for byte indices later.

Behdad Esfahbod cdc673d97c [hb-shape] Add --show-line-num 
Ok, much more useful as a test suite driver now.

Behdad Esfahbod cc4d9810d6 [hb-shape] Add --show-text and --show-unicode options 2012-01-19 12:32:20 -05:00
Behdad Esfahbod 088c1e27c0 [util] Fix option parsing 
Wow, who knew bool is one byte and I was using it as a 4byte int?!

C++ auto casts fails you in mysterious ways...

Behdad Esfahbod 8b8b19056d [util] Add hb-shape utility 
Like hb-view, but prints out buffer contents.

The output format is kinda cryptic.  Suggestions welcome.

Behdad Esfahbod f7e2ef74f8 [hb-view] Make print to stdout work in Windows 
Apparently there's no equivalent to "/dev/stdout", so write using
stdio to be able to output to stdout.
