Hello,

first - thanks for the perfectly synoptical https://wiki.contextgarden.net/Programming_in_LuaTeX#Namespaces !

My question (and the answer sould appear on wiki, too):

Is any of the namespaces (userdata, thirddata, moduledata, documentdata, parametersets) automatically serialized between Ctx first(-second(-third)) runs?

I'm asking because user may call some (longer) code and put the result into a namespace (be it e.g. "userdata"). And if that namespace was automatically serialized for next run(s), that code could be called conditionally - typically just in first run (= mode "*first" enabled) - as in next runs results of the additional code would be available in a namespace (instead of repetitive call of that (longer) code).

Of course, user can perform such evaluation, storage and conditional extra-code-call individually, but maybe there is some support for similar situations in Ctx.

no, if only because they are not meant to store runtime data there is a twopassdata mechanism for storing stuff but other than that you can just write to a file and then check that (depending on what run you have) 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 -----------------------------------------------------------------
