Disproportion in initializing user counters

Disproportion in initializing user counters

[Jaroslav Hajtmar]

[-- Attachment #1.1: Type: text/plain, Size: 913 bytes --]

Hello ConTeXist.
I encountered a disproportion in initializing user counters. Why initialization at the beginning of the source text does not work and what is the mechanism of how the user counters work.

Thanx Jaroslav Hajtmar

Here is a sample example:

\definecounter[mycounter]

\def\getmycounter{\incrementcounter[mycounter]\getnumber[mycounter]}

\startbuffer[groups]
    \startxrow
    \startxcell \getmycounter\stopxcell
    \startxcell Content of column\stopxcell
\stopxrow
\stopbuffer



\starttext

%\setcounter[mycounter][0] % initializing at this point not working (the counter is 10 more than it should be). WHY?



\startxtable
    \startxrow
        \startxcell Column 1\stopxcell
        \startxcell Column 2\stopxcell
    \stopxrow

\setcounter[mycounter][0] % initializing at this point works fine
\dorecurse{5}{\getbuffer[groups]}
\stopxtable

\stoptext

tables take multiple passes so you need to decrement when still 
trialtypesetting

\iftrialtypesetting .. \fi

Many thanks for your reply, Hans.

The original issue was mine, using with the handlecsv module. And I had
no idea about what was wrong there.

Many thanks for your help,

Pablo

Hi Pablo,

when you use the label mechanism to create a counter context ensures to 
print the right counter value in the table.

Hi Wolfgang,

would it be possible to provide me with a minimal sample?

I don‘t use labels and I don’t know how to use them with counters in
xtables.

Many thanks for your help,

Pablo

Easier than counters:

    \definelabel [QQ][text=,headcolor=red]
    \starttext
    \startxtable
       \startxrow
         \startxcell one \stopxcell
         \startxcell two \QQ[there] \stopxcell
       \stopxrow
       \startxrow
         \startxcell alpha \QQ\stopxcell
         \startxcell beta \QQ[here]  \stopxcell
       \stopxrow
    \stopxtable

    See entry \in[here].

    \stoptext

Hi Rik,

I totally agree: this is much easier than counters.

Many thanks for your help,

Thank very much to explain the problem and to example with labels - very useful information for me.
Thanks to all.
