Hi all,
Today I started preparations for my activities at the ConTeXt meeting.
There are two small lua tutorials in the program, and I am looking for input on both. There is one that is supposed to be a general beginner's introduction, and one specifically about fonts.
For both, I am looking for input on what subjects I should cover?
Since both tutorials will end up as articles/wiki pages, it makes sense to ask everybody on the list for input (but requests by actual attendees will be scored considerably higher).
Perhaps some example to modify a font at runtime? I don't know whether that's possible at all, but if yes, it would be great to see how one could modify kerning tables etc. Often a font needs to be groomed but its license places some restrictions on modifying the file itself...

This is somewhat tricky. Actually I had a mechanism for that but I discarded the code. However there will be a feature like that some day as it needs a rather tight integration in the core of context's font handling. (btw, there is a feature for type 1 fonts that adds 'missing' kerns based on shape codes).
And there is font feature files, which, when not broken :), look the same to the OpenType handling code as if the feature were in the original font i.e. no special handling needed.
