Behdad Esfahbod 642135f3b2 [util] In --debug mode, duplicate font data
This has the effect that the font data will end up in a memory
section malloc()ed exactly to its size.  This gives us better
valgrind detection of out-of-bounds access.

Previously, the font data was placed in a mmap()ed section or
GString-allocated area, which didn't have proper protections
at the end when running under valgrind.

Behdad Esfahbod fdd1770e00 Add API/cmdline to show glyph extents when serializing buffer
New API: HB_BUFFER_SERIALIZE_FLAG_GLYPH_EXTENTS

hb-shape now accepts --show-extents.

Patch from Simon Cozens.

Behdad Esfahbod fe97b65a54 [utils] Add hb-fc-list
This is a tool that lists all fonts that can render a given string.
It uses hb_shape() to do so, and as such is aware of HarfBuzz's
normalizer.

Behdad Esfahbod a664810e38 [util] Accept comma as well as space when separating components of args
Applies to --font-size and --margin.

Hopefully the scanf usage here doesn't have compatibility issues
(star being counted in the return value, etc).

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.

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.
