Dear LyX developers,
during the LaTeX export, LyX adds to the preamble a number of required
"features" (package loading commands and auxiliary definitions) if the
function ``LaTeXFeatures::mustProvide(string const & name)`` return true.
I want to refine this test (part of bug #9637):
The font-encoding switching definitions in "textcyr" and "textgreek"
features are provided by Babel, if a corresponding language definition
file is loaded:
* textcyr: for languages with FontEncoding T2A
* textgreek: for languages with FontEncoding LGR
Plan: after all the languages used in the document are known,
check which "FontEncodings" are provided by these languages.
If LGR is in these font-encodings, textgreek is provided
If T2A is in these font-encodings, textcyr is provided
Problem: How to do this check-loop?
How/where to add the provided features?
Günter
