I am making some slides using the Swoosh style in simpleslides module.
I wanted to reveal some content sequentially.
simpleslides does not support stepwise presentation of material.
I occasionally use the following macros for quick and dirty stepwise
effects. This is for really simple material (no counters, no glues ...)
\usemodule[simpleslides][style=Swoosh]
\def\StartSteps#1#2\StopSteps%
{\dorecurse{#1}{\long\setvalue{\recurselevel}{\gobble}}
\dorecurse{#1}{\long\setvalue{\recurselevel}{\oneofone} #2}}

Hi,
this is awesome, but could you please explain why it works? I don't
understand what is defined by \def\StartSteps#1#2\StopSteps and also
\def\StartSteps#{count}#{body}\StopSteps
{% Initialization
% for i = 1 upto count :
% set csname(i) = gobble
\dorecurse{#{count}}{\long\setvalue{\recurselevel}{\gobble}}
%
% Now typeset #{body} for #{count} number of times.
% In each iteration set csname(i) = oneofone
\dorecurse{#{count}}
{\long\setvalue{\recurselevel}{\oneofone}%
#2}}
why are \gobble and \oneofone used in such a way when they are
single-argument commands.
I could have just \letvalue{\recurselevel}\gobble and
\letvalue{\recurselevel}\oneofone.
Aditya
