I hope it is clear now why raw values from the font are needed. fwiw it looks a bit too excessive to me (i'm not sure if graphical elements like those accents which are part of the character needs that much protrusion) Many thanks for your help, Pablo ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___ -- - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Re: [NTG-context] Problems with setups module
Hi Tommaso,
I sent a fix to the dev list and the problem should be fixed in a new beta.

Hi everyone.
The following code gives different results by commenting and

Could it be a problem with the setups module?

[NTG-context] Grammar to parse TeX input?
Dear list,
I use a buffer to make some text processing. That text contains TeX macros etc…
and I’d like to know if there is some feature in lua to parse the text to
extract bits which macros, normal text etc… ?
Thanks
Best regards
Joseph
Example of pseudo MWE follows.
\startluacode
function zzz_function(text)
