Hi, list! I've tested the Harfbuzz plugin in ConTeXt and it works nicely
for most cases. However, color doesn't seem to work. Is this intended? I
know this plugin won't be supported, but I'll be fine with pointers to
solve this issue. Thanks in advance.
\usemodule[fonts-plugins]
\definefontfeature[harf]
[mode=plug,
features=harfbuzz,
shaper=native]
%Just to test Harfbuzz is actually working
\definefontfeature[devaA][harf]
[language=dflt,
script=deva]
\definefontfeature[devaB][default]
[script=deva]
\definefontfeature[colored][harf]
[language=dflt,script=arab,
colr=yes] %doesn't do anything
\startbuffer[hindi]
i honestely have no clue if color will work (also because hb is in a
sort of continuous flux wrt updates and so, and i tend not to update
libraries without knowing why) .. as long as there is nothing needed
that is handled by node mode such things should work
keep in mind that this is just there because idris and i wanted to
compare the output different rendering approaches (on windows one can
use the uniscribe mode and uniscribe is sort of the reference so in case
of doubt we try to follow that) but i haven't looked at if for years
using that plugin is it's a bit of a gamble wrt what features to enable
adn what heuristics kick in, but you can try at least to enable arabic
\definefontfeature[colored][arabic,harf]
[language=dflt,script=arab,
colr=yes] %doesn't do anything
however, it looks like i have to itercept a default color (doesn't
relate to plugins) so i'll send you the one-line patch for that (at
least in node mode that works)
