Steps in presentation

Hello,

I tried to use some steps in a presentation.  In the following conversation
http://www.mail-archive.com/ntg-context@ntg.nl/msg53524.html, Wolfgang says
that we can use the pre-60 module.  So I tried this snippet:

\usemodule[pre-stepwise]

\starttext

\StartSteps

\startitemize
\item one \FlushStep
\item two \FlushStep
\item three \FlushStep
\stopitemize

\StopSteps

\stoptext

But it does not compile:

ConTeXt  ver: 2012.09.11 20:36 MKIV  fmt: 2012.9.12  int: english/english

Is there something broken in recent release of conteXt?  By the way It seems
there is no Rawsteps module anymore but it still is in the wiki. Is there is
something like a bugtracker for conteXt, in order to signal when  a feature is
not working or outdated and signal when it is back (or definitly depreciate)?
(it would be a complementary tool for the mailing list)

I'm following on an old thread about the RawSteps Module, which is
broken in MKIV. Trying to move to MKIV, this is a "no go" for me since I
absolutely need this module for teaching. I've contacted David Munger,
the author of the module,  last September, which had been a real helper
in the past about this module, but he has presently no time to work on
this. If someone know how to fix the problem, I provide a short minimal
exemple:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \enableregime[utf] 
\usemodule[rsteps]

\setupcolors[state=start] \setuppapersize[S4][S4]

\starttext

\StartSteps \startformula 
 \eqalign{ P[\text{atteindre l'état}\ j | \text{partant de } i] 
  & = P\left[\bigcup_{n=0}^\infty (X_n=j)| X_0 = i\right]\cr
  & \leq \sum_{n=0}^\infty P[X_n=j|X_0=i]\cr 
  & =\sum_{n=0}^\infty P_{ij}^n =0 \cr } 
\stopformula \StopSteps

\StartSteps \startformula
\eqalign{
  \FromStep[1][reserve]{P[\text{atteindre l'état}\ j | \text{partant de } i]} &
  \FromStep[1][reserve]{= P\left[\bigcup_{n=0}^\infty (X_n=j)| X_0 = i\right]}\cr &
  \FromStep[2][reserve]{\leq \sum_{n=0}^\infty P[X_n=j|X_0=i]}\cr &
  \FromStep[3][reserve]{=\sum_{n=0}^\infty P_{ij}^n =0 }\cr } 
\stopformula
\StopSteps

\stoptext 
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 
%%%%%%%%

Also, here is the contextHarden link:
http://wiki.contextgarden.net/RawSteps

If somebody know another solution to show content by step in a page, I
would be happy to know about it. Thanks, Fabrice.

Dear Fabrice,

The following code is working in my mac. I tried your first code and it is working after adding \setupinteraction[].
Since I didn’t use ‘rsteps’ module, I could’t test the second code.

My ConTeXt version is as following.

ConTeXt  ver: 2014.12.21 22:25 MKIV beta  fmt: 2014.12.26  int: english/english


\setupinteraction[state=start]
\setupcolors[state=start] 

\usemodule[pre-60]

\setuppapersize[S4][S4]

\starttext

\StartSteps 
\startformula \startalign
\NC x^2 + y^2  \NC  = z^2 \NR \FlushStep
\NC   x^2 + y^2   \NC = z^2 \NR  \FlushStep
\stopalign\stopformula
\StopSteps
\stoptext

I hope that this helps.

Best regards,

Dalyoung
