Behdad Esfahbod e60350551a [hb-shape] Improve shaping-debug output
Before, that was printed using --debug (and in both hb-shape and hb-view).
Changed it, now hb-shape has a new command-line argument called --show-messages.
When invoked, it also respects other output formatting options.  The messages
are better formatted and printed to te same place that hb-shape output is
directed to.  Previously they were written to stderr.

Behdad Esfahbod 111f3e5517 [util] Add --variations
Is hooked up to the font, but not to FreeType, so raster doesn't show yet.

Documentation needs to be done.
2017-01-21 17:51:41 -08:00
Behdad Esfahbod 21e5d7edc4 [util] Use O_BINARY instead of _O_BINARY
The latter doesn't seem to be available in Cygwin.  I'm surprised it
compiled before...

Chun-wei Fan 998e8dda93 util: Fix build on Visual Studio
Use the fallback implementation for lround() only on pre-2013 Visual
Studio, and ensure we are clear about the types of the parameters for
lround() and scalbnf(), since Visual Studio can be quite picky on
ambiguous parameter types.  Also, use g_ascii_strcasecmp() rather than
strcasecmp() as we are already using GLib for this code and we are
assured that g_ascii_strcasemp() is available.

For scalbnf() on pre-2013 Visaul Studio, a fallback implementation is
needed, but use another forced-included header for those compilers, which
will be added later.

Also use (char)27 on Visual Studio builds as '\e' is not a recognized
escape sequence, which will do the same thing.

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

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 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.

Behdad Esfahbod 7cba8a673b Fixup previous commit
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.

Two output formats for now: TEXT, and JSON.  For example:

Deserialization API is added, but not implemented yet.

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.

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 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.
