Fvector is less error-prone than make_uninit_vector, as it
avoids the possibility of a GC crash due to an uninitialized
vector. So prefer Fvector to make_uninit_vector when this is
easy (and when there's no significant performance difference).
Inspired by a suggestion by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2020-08/msg00313.html

Prefer Fvector to make_uninit_vector when either is easy.
* src/fontset.c (font_def_new): Now a function with one less
arg instead of a do-while macro, and renamed from FONT_DEF_NEW.
All uses changed.

* src/hbfont.c (hbfont_shape): Don't use DIRECTION if the current

* src/hbfont.c (hbfont_shape): Don't assume LGLYPH_TO is
always a fixnum.
* src/fontset.c (fontset_find_font): A cleaner test for
matching charset_id.
|
|
* src/hbfont.c: Include hb-ot.h.
[HAVE_NTGUI]: Add DEF_DLL_FN and #define for hb_tag_to_string,
hb_font_get_face, hb_ot_layout_table_get_script_tags,
hb_ot_layout_table_get_feature_tags, hb_ot_layout_script_get_language_tags,
and hb_ot_layout_language_get_feature_tags.
(hbfont_init_w32_funcs) [HAVE_NTGUI]: Add LOAD_DLL_FN for them.
(hbfont_otf_features, hbfont_otf_capability): New functions.
* src/font.h (hbfont_otf_capability) [HAVE_HARFBUZZ]: Add extern.
* src/ftcrfont.c (syms_of_ftcrfont_for_pdumper) [HAVE_HARFBUZZ]:
* src/ftfont.c (syms_of_ftfont_for_pdumper) [HAVE_HARFBUZZ]:
* src/w32uniscribe.c (syms_of_w32uniscribe_for_pdumper) [HAVE_HARFBUZZ]:
* src/xftfont.c (syms_of_xftfont_for_pdumper) [HAVE_HARFBUZZ]: Populate
otf_capability method with hbfont_otf_capability.
|
|
* src/hbfont.c (hbfont_shape): Fix setting TO of lglyph for
the case when Lisp shape-gstring function performed some
compositions by itself. This happens with hebrew.el. See
https://lists.freedesktop.org/archives/harfbuzz/2019-June/007396.html
for the details of the problem this solves.
|
|
|
|
* src/hbfont.c (hbfont_shape): Use ptrdiff_t, not int,
for indexes that in theory might overflow int.
Add UNINIT to pacify GCC 9 and omit an unnecessary initialization.
|
|
|
|
* src/hbfont.c: New file, with code moved from w32uniscribe.c
and renamed/modified as appropriate.
* src/w32uniscribe.c: Move to hbfont.c DEF_DLL_FN and macro
definitions for HarfBuzz functions used in hbfont.c
(load_harfbuzz_funcs): Move loading of HarfBuzz functions used
by hbfont.c to hbfont.c:hbfont_init_w32_funcs, and call that
function from here.
(syms_of_w32uniscribe_for_pdumper): Fill the 'shape' and
'combining_capability' members with hbfont.c function names.
* src/w32common.h (hbfont_init_w32_funcs) [HAVE_HARFBUZZ]: Add
prototype.
* src/font.h (hbfont_shape, hbfont_combining_capability)
[HAVE_HARFBUZZ]: Add prototypes.
* src/Makefile.in (SOME_MACHINE_OBJECTS): Add hbfont.o.
* configure.ac (FONT_OBJ): Add hbfont.o if HAVE_HARFBUZZ.
