Ebrahim Byagowi 9b3d4f457e Use dagger in hb_ot_layout_feature_get_characters
The way it used to work was a bit nonidiomatic but the replacment
is idiomatic way of iterating used elsewhere.

The new code just doesn't check nullability of "characters", which isn't
what we do anywhere else.

Behdad Esfahbod b2a1acccd9 Simplify get_glyph_alternates() dispatcher
Trying to make it **very simple** to add a specialized dispatcher for

2020-06-18 16:41:31 -07:00
Behdad Esfahbod ffe8d3f39d Use dispatch for get_glyph_alternates_t
First time we do this in a way that if target object doesn't have the matching
function we basically "ignore".  Risky but I feel like is the right decision
for this case.

I'm going to put back the template varargs and use those, which would make
the dispatcher be just that: "dispatcher", and wouldn't need to carry the
call context.  That would be a refreshing change I think.

Christoph Reiter 03bd6ead44 [meson] Only pass required dependencies to everything
Instead of passing dependencies as required we used one giant shared
dependency list containing all dependencies for every library/executable.
While this kinda works, the specified deps are also used for generating
the pkg-config files and this leads to lots of Requires.private and Libs.private
entries which aren't really needed.

This removes the "deps" array and replaces it with a few smaller ones and
makes sure the public libraries only get passed the dependencies actually
needed.

Ebrahim Byagowi c68ab4b52b Fix _get_ligature_caret's oob read issue
AAT::Lookup has no other way to detect whether it is returned from
a real and sanitized font data or from a null pool, this checks if
the table has been recognized valid by sanitizer by checking
table's major version which is zero if returned from a null pool and
non-zero if is from a sanitized font data, it is expected the other
calls of the table (unlikely to have more calls however) also do a
similar version check before calling the lookups used on the table.

Instead, if introspection is explicitly enabled but gobject is for some reason
missing error out.

[aat] Fix implementation of AAT kerning for Geeza Pro. (#2388)
* [aat] Fix implementation of AAT kerning for Geeza Pro.

Despite what the comment in the code used to say, it appears that Geeza Pro
does rely on accumulating kerning values from successive subtables. With
this change, the results now match Core Text rendering (and avoid the clear
visual breakage reported in #2358).

Testcase: U+0644,U+064E,U+0645,U+064E,U+0651,U+0627

Fixes #2358.

* [aat] Update test expectations, add new testcase.

Khaled Hosny 09b9d63e56 [blob] Try to support resource fork fonts on macOS
If the size of opened file is zero, try opening resource fork by
appending "/..namedfork/rsrc" to the file name. This is guarded with
__APPLE__ ifdef and uses _PATH_RSRCFORKSPEC macro from sys/paths.h.

Defining HB_NO_RESOURCE_FORK will disable this fallback.

Christoph Reiter 8ae06c9489 meson: build a separate library for harfbuzz-icu
This adds a seperate library like with autotools.

This also fixes the ico feature option which was just set to required:false
when disabled instead of really disabling it.
Disabling is still broken with msvc because it then tries to find the library
another way, but that's broken for all other deps as well so I left it as is.

For tests only test-unicode.c is using icu specific functions so split it out
into its own category which depends on harfbuzz-icu.

Khaled Hosny 14b5c774c2 meson: Fix include directory when used as subproject
HarfBuzz headers are under src/ not the root directory, without using
incsrc no headers will be found by the dependent project. I think
incbase is superfluous, it should be replaced by incsrc or dropped.

Tim-Philipp Müller d230a02048 meson: generate .def file for MSVC symbol export on the fly
Fix symbol export with MSVC when features are disabled,
such as GLib. We need to generate the list of exported
symbols on the fly to make sure we only export symbols
that are actually available.

Needs some minor modifications to the gen-def.py script:
 - accept header list also via command line args; we can't
   pass things to a configure_file() command via the environment
   in Meson.
 - strip any leading 'src/' from library filename. This might
   be there because in Meson the script might be called from
   the top-level directory and not the current source directory.

Remove .def files again which had been checked in for earlier
versions of the Meson port.

collect_unicodes() with clamp, calling add_range()
Use add_range instead an inner loop, clamp its input number by
number of glyphs a face has.

Even the face cmap12 and 13 have 32-bit hb_codepoint_t, which is here
used to make timeout, face's maxp has 16-bit gid limitation at least for now,
using that makes sure we both fix and the timeout and don't need to change
much things here also in order to support 32-bit gids also someday.

accepted here goes to it, maybe an additional check can be put there
also, this however feels to be enough.
