f95a87b7b8 [util] List supported output formats in hb-view 2012-12-21 16:35:28 -05:00
Behdad Esfahbod
6bad092aa8 [util] Default to "text" output format in hb-shape 
If you say:

  hb-shape font.ttf text --output-file out.txt

This was previously failing:

  Unknown output format `txt'; supported formats are: TEXT / JSON

Now we simply fallback to TEXT if no explicit format was requested.

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.

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.

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.

isn't such a bad idea...

d530024168 [util] Make clusters work with char offset instead of UTF-8 offset

Will add an option for byte indices later.

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'.

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.
