Hi,

I am used to giving very extensive feedbacks to my pupils. These are buffers with xtables flushing lua vectors. Here is their basic structures:

* an environment that stores xtables. Turned into MWE, look like:

   \startenvironment env_corrige.mkiv

   \startluacode       userdata = userdata or {}    function userdata.Critere (commentaire,note,notemax)       context.startxcell {"width=11cm","height=2.75cm"}          context(Eleve[commentaire])       context.stopxcell ()       context.startxcell {"width=1.5cm","align=flushright"}          context(Eleve[note])          context("/")          context(notemax)       context.stopxcell ()    end    \stopluacode

   \startbuffer [grille]    \startxtable       \startxrow          \startxcell             \ctxlua {userdata.Critere ("structure","NoteStructure",2)}          \stopxcell       \stopxrow    \stopxtable    \stopbuffer    \stopenvironment

* The main file is divided in subjects, each one of them being the feedback to one pupil. In a MWE fashion

   \useenvironment [env_corrige]    \starttext    \startsubject[title={Astérix}]    \startluacode    Eleve = {       structure = "analyse très fine",       NoteStructure = 2,    }    \stopluacode    \getbuffer [grille]    \stopsubject

   \startsubject[title={Obélix}]    Eleve = {       structure = "le détail doit être travaillé. Pensez à la finesse de vos menhirs…"       NoteStructure = 1,    }    \stopsubject    \getbuffer [grille]    \stoptext

Since whatever I fill in those files is written inside luacode environment, I tried to switch to cld documents.

Here is my main file in cld version

   context.useenvironment({"env_corrige"})

   context.starttext()

   context.startsubject({title="Asterix"})

   Eleve = {       structure = "analyse très fine",       NoteStructure = 2,    }    context.getbuffer({"ExoCorrection"})    context.stopsubsubject()

   context.startsubject({title="Obélix"})

   Eleve = {       structure = "le détail doit être travaillé. Pensez à la finesse de vos menhirs…"       NoteStructure = 1,    }    context.getbuffer({"ExoCorrection"})    context.stopsubsubject()    context.stoptext()

The troubles is that buffers are filled with the last version of Eleve table. I guess this is because the whole file is parsed and then filled in buffers. My understanding of the cld manuel is that context.tobuffer() and context.direct()

should be used, but couldn't figure out how. Tried several times, also with context.step but all failed. I think I didn't properly understand the "temp" and str of context.tobuffer description in manual.

What changes should I introduce to my cld files? see attached ... it's more that you overload Eleve ... an alternative is to make a function that gets that table as (then local) argument but I don't want to touch your code too much

the function wrapper sort of delays (immediate evaluation is a general problem, of function driven typesetting, which is why in the end a pure function driven one is not better / easier than tex) 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 -----------------------------------------------------------------
