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
Best regards,
Marcel
