Re: [NTG-context] [doifinset] how it works ?
Hi,
Here are a few examples of how to use \doifinset and \doifinsetelse (they were
given by Wolfgang S. a few years ago…):
\starttext
\type{\doifinset{A}{A,B,C}{should go}:} \doifinset{A}{A,B,C}{should go}
\type{\doifinset{D}{A,B,C}{should go}:} \doifinset{D}{A,B,C}{should
participate}
\type{\doifnotinset{}{A,B,C}{not in the set}:} \doifnotinset{}{A,B,C}{not in
the set}
\type{\doifnotinset{D}{A,B,C}{not in the set}:} \doifnotinset{D}{A,B,C}{not in
the set}
\doifinsetelse{D}{A,B,C}{it is in the set}{it is not in the set}
\define\test{B}
\type{\doifinsetelse{\test}{A,B,C}{\test\ is in the set}{\test\ is not in the
set}}
\doifinsetelse{\test}{A,B,C}{\test\ is in the set}{\test\ is not in the set}
\stoptext
Best regards: OK

Hello,
I'm currently prepping my teaching material for my back-to-university.
I want to design some conditional slides based presentation where I can
select the slides that I want to show in my final presentation.
My current attempt is to use :
1 - MKIV as I use currently only MKII;
2 - a counter is defined, that it is incremented at each slide definition;
3 - a commalist to indicate the slides that I want. The number affected to
each slide is made according to its definition in the file and not the slide
number displayed;
4 - a block is added to enclosed each slide in order to allow or not it to be
shown in the final presentation.
\definenumber[slide][way=bytext,prefix=no]
% firstly I generate a full commalist
\def\slidelist{}
\dorecurse{8}{
\doglobal\appendtocommalist{#1}\slidelist
}
% then I define my slide where I increment the counter
\def\startSlide{\setupbackgrounds[page][background={fond,Auteur,backgraphics,foreground,foregraphics}]
\directsetup{slide:start}}
\def\stopSlide{\directsetup{slide:stop}}
\startsetups slide:start
\page
\incrementnumber[slide]
\switchtobodyfont[14pt]
\setupinteractionbar[state=start]
\startnarrower[left]
\stopsetups
\startsetups slide:stop
\stopnarrower
\page
\stopsetups
\starttext
\doifinset{\getnumber[slide]}{\slidelist}
{
\startSlide
\SlideTitleSub{Hello there}
What is my number ? \getnumber[slide] !
\stopSlide
}
\stoptext
This doesn't work. the doifinset doesn't work. I've tried to put some
\expanded in order to expand the arguments with no success.
The only way is to use direct argument as :
\doifinset{1}{1,2,3,4,5}
Let me know it it is possible.
best regards,
Pierre-François Bonnefoi.

You have to access the counter with \rawcountervalue[countername] but in your
case you can use a different counter mechanism.
\setvariables[slide][list={1,2,3,6,7,8}]
%
\setupbackgrounds[page][background={fond,Auteur,backgraphics,foreground,foregraphics}]
\def\startSlide
{\increment\SlideCounter
\doifinsetelse\SlideCounter{\getvariable{slide}{list}}
{\directsetup{slide:start}}
{\gobbleuntil\stopSlide}}
\def\stopSlide
{\directsetup{slide:stop}}
\startsetups slide:start
\page
\stopsetups
\startsetups slide:stop
\page
\stopsetups
\starttext
\dorecurse{10}
{\startSlide
{\tfd\recurselevel}
\stopSlide}
\stoptext

Hallo,
on the garden at
http://wiki.contextgarden.net/System_Macros/Branches_and_Decisions
one can read to the command \doifinset
'If the first string expands 'empty', it is considered to be always
in the set.'
But
\starttext
\doifinset{}{A,B,C}{should go}
\stoptext
seams to show that this is wrong.
Is my example wrong or my understanding of the above sentence?
The sentence is wrong, if the first argument is empty ConTeXt considers
the argument to be *not* in the set (verified in the source).
