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 c8149ca85e [hb-shape] Adjust postioning output format
1. If there is any offset (x or y), print out both x and y offsets.

2. Always print out the advance in the major direction of the buffer.
Ie. even for zero-advance glyphs, print a "+0".  This is more intuitive.

Behdad Esfahbod bdc48a879a Enlarge glyph_name buffer
Lohit Devanagari has a glyph named:
u0924_u094D.half_u0930_u094D.blwf.vatu
2012-08-04 17:08:38 -07:00
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 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 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 e700bce118 [util] Add hb-diff
A diff program written in Python that is more suitable for comparing
hb-shape output from different backends.  Main differences with stock
diff:

1. It outputs one line's comparison at a time, as opposed to batching
'+' lines and '-' lines.

2. It colors the part of the line that changed, taking word boundaries
into consideration.

You can pipe the colored output to 'less -r'.

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 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.
