Hi,

The following document

\directlua{ local arch = gzip.compress"I will become much much smaller, once the overhead is compensated" local orig = gzip.decompress(arch) print(arch:len(), orig:len(), orig) } \starttext \stoptext

used to work in ConTeXt mkiv and still works in ConTeXt lmtx, but for current mkiv versions it breaks with

...mtx/tex/texmf-context/tex/context/base/mkiv/util-zip.lua:610: attempt to call a nil value (upvalue 'tocardinal1') stack traceback: ...mtx/tex/texmf-context/tex/context/base/mkiv/util-zip.lua:610: in upvalue 'putcompressed' ...mtx/tex/texmf-context/tex/context/base/mkiv/util-zip.lua:662: in function 'gzip.compress' [ctxlua]:1: in main chunk

i'll check it (at some point i need to split code paths a bit more i think) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
