I’ve tried context.processbuffer but I am afraid it’s not what I am after, most probably I have not phrased clearly my question.
What I am looking for is roughly what’s described in Taco’s presentation https://meeting.contextgarden.net/2014/talks/2014-09-12-taco-luatex/luatextalk.pdf A way to decompose some input into tokens which represent either normal text, csnames etc… I had a try to this token library in LuaTeX but I could not find examples of how to use it. I suspect that buffers mechanism use it somehow.
