I can’t get the example in the m-barcodes module to work. I have no urgent need to print barcodes; I was just curious. I'm writing in case I found an easily corrected bug. The release notes from 2010.05.08 call this module mkiv only. But according to the log, the file m-pstricks.mkii is used. And that seems to be the proximate cause of the error. mjg ------------------------------------- ConTeXt ver: 2010.06.23 12:45 MKIV fmt: 2010.7.6 int: english/english ------------------------------------- command: context "barcode-test.tex" ------------------------------------- file: barcode-test.tex \usemodule[barcodes] \starttext % this is copied straight from m-barcodes.mkiv \startPSTRICKS \pspicture(-4mm,-1mm)(38mm,26mm) \psbarcode{9781860742712}{includetext guardwhitespace}{ean13}% \endpspicture \stopPSTRICKS \stoptext ------------------------------------- log before the error: systems : begin file barcode-test-pstricks-0001 at line 1 system : module pstric loaded (/context/tex/texmf-context/tex/context/base/m-pstricks.tex (/context/tex/texmf-context/tex/context/base/m-pstricks.mkii !
