Hello everyone, First, thanks for making this list such a great resource. I've installed a fresh minimals on windows using first-setup.bat. This seems to have installed luatex 0.40.6 which led to errors making the formats (message indicated at least 0.42 was needed). I think the presence of the older luatex version for windows was recently noted on another thread. So, I installed 0.42.0 and remade the formats. This minimal example works with "texexec example.tex" but fails with "context example.tex". \startMPinclusions input metaobj; \stopMPinclusions \starttext \startMPpage newBox.a(\sometxt{hello world}); a.c = origin; drawObj(a); \stopMPpage \stoptext Is this expected to work (I realize the 0.42.0 is very new) Am I doing something wrong? Thanks very much for any assistance, Matt C:\wk\tex>context example.tex MTXrun | run 1: luatex --fmt="C:/wk/cm/context/tex/texmf-cache/luatex-cache/cont ext/e8705fc03b81c76af2e2d42634ded96b/formats/cont-en" --lua="C:/wk/cm/context/te x/texmf-cache/luatex-cache/context/e8705fc03b81c76af2e2d42634ded96b/formats/cont -en.lui" --backend=pdf "./example.tex" This is LuaTeX, Version beta-0.42.0-2009071712 \write18 enabled.

Is this expected to work (I realize the 0.42.0 is very new)
I am not surprised it fails. Most metapost code in mkiv is run at least twice for some reason, and so equations tend to fail. You could try with \startMPpage newBox.a(\sometxt{hello world}); a.c := origin; drawObj(a); \stopMPpage but even then it depends on what newBox does internally. Best wishes, Taco

in general one needs to keep in mind that we're in one run, so even in the case of 'single runs' things can bleed from one to the other graphic; one should set up graphics as independent as possible Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
Hi Matthew, I've been playing with metaobj and luatex 0.43 for a bit, and faced similar problems. Lots of stuff about "redundant" equations and other stuff I didn't understand. However, I've found that cleaning up your objects when you're done pretty much solves all my problems. For example, just add a clearObj line to your code makes it work for me: \startMPinclusions input metaobj; \stopMPinclusions \starttext \startMPpage newBox.a(\sometxt{hello world}); a.c = origin; drawObj(a); clearObj a; \stopMPpage \stoptext I'm not completely sure why this is clearObj a (and not clearObj(a), which seems to be more logical considering drawObj also takes parentheses), but that's probably something of the wonderful world of macro "programming". Hope this helps, Matthijs
Hi Matthew,
However, I've found that cleaning up your objects when you're done pretty much solves all my problems. For example, just add a clearObj line to your code makes it work for me: I've found that using "save" to "declare" the values as local also works. For example:
\startMPinclusions input metaobj; \stopMPinclusions
\starttext \startMPpage save a; newBox.a(\sometxt{hello world}); a.c = origin; drawObj(a); \stopMPpage \stoptext
Perhaps this is even slightly more elegant. Gr. Matthijs
