Hi all,
I can’t explain the following behavior of the .tuc writer. When
passed a nested hash, context fails on the second pass if the
array part of the first nesting depth is empty:
·······································································
%% the commented lines work
\startluacode
job.variables.tobesaved.foo = { bar = { } }
-- job.variables.tobesaved.foo = { "works now", bar = { } }
-- job.variables.tobesaved.foo = { bar = "works too" }
\stopluacode
\starttext foo \stoptext
·······································································
I get this error:
·······································································
! LuaTeX error ...text/tex/texmf-context/tex/context/base/cldf-ini.lua:410: no string to print

·······································································
Bug?
Regards
Philipp

From my reading of core-dat.lua I gather that there is not really a way to dump any Lua table (array or hash or mixed) via datasets.

Except directly writing to “tobesaved”. And that is indeed somewhat nasty; I'll add a 'convert' key to the settings so that you can set raw data at the Lua end. (I'll send you a Lua file for testing) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl ----------------------------------------------------------------- ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 4+ messages in thread
