Hello,
The luatex documentation contains in section "7.2.2 Example virtual font" an example how to define a virtual font "cmr10-red". The font is defined by adding the code to the define_font callback.
Does some interface exists in contex/mkiv which allows to use such virtual fonts together with the normal font loading code? E.g. could I move the code for the font to some file ("cmr10-red.vflua") so that a request \font\mytest="cmr10-red" will simply find this file and use the code like vf, tfm or otf-files are found and used when needed?
It's relatively easy to add support for that.
That would be fine. There are quite often on various lists questions about how to "correct" a font, e.g. adjust kerning, or add a missing glyph etc and a interface for "virtual lua fonts" would make such corrections much easier.
The example in the documentation uses as base font cmr10 and loads it with f = font.read_tfm('cmr10',size). How should one load the real font when it is an otf?
the lua file has to return a function that then gets a specification and has to return a tfmtable, something like return myhackery(specification) local t = fonts.tfm.read(specification) -- mess around with t return t end but I didn't test that.
