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).

Great! How can this feature be triggered?

happens automatically

\usetypescriptfile[type-ghz]

\enabletrackers[afm.features]

\starttext

\definetypeface[main][rm][serif][melior][default]

\setupbodyfont[main]

test

\stoptext

reports (when not cached):

load afm> add ligatures load afm> add tex-ligatures load afm> add extra kerns

Where does it report these lines?

I looked at terminal output and compared the log files (no difference with/without enabletrackers) in vain.

"when not cached" does mean the first time typesetting, no?

fonts are cached so you will only see this if you erase the font cache ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
