Jonathan Kew 58b4d18b53 Add a couple testcases for issue 2285. 
A few simple testcases to confirm that setting liga=0 does not break shaping with
the Tibetan AAT font Kokonor, but does still disable common ligatures in Times.
 2020-04-02 23:58:32 +04:30
Jonathan Kew b1c0b9da2f [AAT] Don't map OT tags to AAT feature types that are not exposed. 
If an AAT feature type is not exposed in the 'feat' table, we assume it is not intended
to be user-controllable and so we should not map any OT feature tag requests to it.

Fixes #2285.

Simon Cozens bdda2ff609 More strictly follow noun/verb/identifier format for GPOS/GSUB lookups 
Less generic than the previous commit, but more descriptive and more consistent.

Simon Cozens bef7ef81da Reformat kerx/morx instrumentation to 'verb noun identifier' 2020-03-30 16:39:43 +01:00
Simon Cozens 42aac64030 Add table index to lookup messages 
We could say GSUB/GPOS explicitly, but using the index is more general, in case future tables (such as JSTF, Silf) become supported.

Ebrahim Byagowi 18fc9197e2 [meson] Run check-symbols.sh and check-static-inits.sh correctly 
* Search src/ build directory for objects in check-static-inits.sh
* Find .def files in src/ build directory in src/check-symbols.sh
* Pass builddir also in autotools also, we may just remove libs passing after autotools removal
* Move harfbuzz_subset_def target so can be referenced as a check-static-inits.sh dependency

Ebrahim Byagowi b143e34ee1 [gsubgpos] Initialize variation index on HB_NO_VAR 
hb_shape_plan_key_t::equal expects hb_ot_shape_plan_key_t be initialized by
hb_ot_layout_table_find_feature_variations calls but it won't get initialized
when HB_NO_VAR build config is used.

Tim-Philipp Müller 93b3e30215 [meson] fix icu-related linking errors in test with amalgam build 
test-unicode.c:960: undefined reference to `hb_icu_get_unicode_funcs'
test-unicode.c:961: undefined reference to `hb_icu_get_unicode_funcs'

For now add the icu sources to libharfbuzz also for the amalgam
build, later we need to have a separate harfbuzz-icu module and
link against that, and/or generate harfbuzz.cc.
