Behdad Esfahbod c462b32dcb Disable automatic segment properties guessing
Before, if one called hb_shape() without setting script, language, and
direction on the buffer, hb_shape() was calling
hb_buffer_guess_segment_properties() on the user's behalf to guess
these.

This is very dangerous, since any serious user of HarfBuzz must set
these properly (specially important is direction).  So now, we don't
guess properties by default.  People not setting direction will get
an abort() now.  If the old behavior is desired (fragile, good for
simple testing only), users can call
hb_buffer_guess_segment_properties() on the buffer just before calling
hb_shape().

Behdad Esfahbod e2aab4b5db Improve checks for setmode()
As reported by Jonathan, OS X has setmode() that is something other
than what setmode() is on Win32.  So, limit invocation to Windows
platforms only.

Thanks to Khaled for spotting it.

Now, it looks like this breaks Cygwin again.  Have to figure out what's
going on.
2013-01-31 18:37:10 -05:00
Behdad Esfahbod bc76449f51 Use setmode() instead of _setmode()
Looks like Cygwin / MSVC declare it that way, and it still works on
MinGW32 cross.

Behdad Esfahbod 1172dc7362 Rename hb_buffer_clear() to hb_buffer_clear_contents()
The previous name was clashing with harfbuzz.old.  There are systems
that need to link both...

Clash-free now again.

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.

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 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 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 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.
