Hans, using latest from today (and the previous one) with the following source:
\starttext \doloopoverlist{\tf,\ss,\tt} {\bgroup\recursestring% \doloopoverlist{\tf,\it,\bf,\bi,\sc} {\bgroup\recursestring\dorecurse{26} {\character{\recurselevel}̱ }\par}\egroup} \stoptext I get the following error: mtx-context | fatal error: return code: 1 But when checking the sources, no error is found: $ mtxrun --script check test-file.tex no error Just in case it helps, creators are "LuaMetaTeX 2.10 20220818 + ConTeXt LMTX 2022.08.25 17:43". I don’t know whether I’m missing something (in that case, the error message should be more verbose). 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 / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________
