Any chance that this typescript could find a way to the main ConTeXt distro?
normally typescripts like that end up in tex/context/third (maybe at some point we can collect extra typescripts in one package)
I can add it to my typescript collection.
a few suggestions:
\definefontfeature[slanted][default][mode=base,slant=.25]
best define "roboto-slanted" as you don't want to overload other definitions of slanted and this is rather font specific .. and are you sure you want base mode here?
Yes it is necessary because it doesn’t work when you use node mode.
\definefontfeature[roboto-slanted][slant=.25]
\definefontsynonym [\s!SerifItalic] [\s!Serif] [\s!features={default,roboto-slanted}]
should also work and delays default
This older doesn’t work, only with “robot-slanted,default” the font gets slanted.
also, name type typescript type-imp-roboto.tex (or .mkiv)
