Hi David and all ConTeXters,
I was away from my e-mail so I am late in answering.
Thank you for the file you put on your site. Indeed everything works
as intended (the \placeformula no longer advances with each step),
and I think one may suggest to Hans to include this in future
distributions.
However, in the spirit of ConTeXters who are always asking for a
step(!) towards perfectness, I let you know the following drawbacks
of the macros:
1) Somehow the \FromStep[n][reserve] changes the internal mechanism
of glue or spaces in displayed formulas. So one needs (as you do in
your example) to add \; around operators such as +, -, =. Can one
avoid this?
I'm sorry, I'm no TeX/ConTeXt guru and I really have no idea of how to
achieve this. I think now we need Hans' help.
I have indeed noticed that enclosing an operator between braces breaks
the spacing system. Try, for instance:
\startformula
\vec\nabla\cdot\vec u = 0
\stopformula
\startformula
\vec\nabla\cdot\vec u {=} 0
\stopformula
Unfortunately, using \phatom{=} results in the same broken spacing as
second formula.
2) When one refers (see example below) with the command (\in[eq:NS])
to an equation which has been introduced with \placeformula[eq:NS]
the interaction makes appear the first instance of that formula,
which may be incomplete. Could one have a control over this, that is
for instance, in this particular case, make appear the completed
equation at the end of the slide made with \StartSteps[Navier||Stokes
equation]?
Good point! Here's the fix (file updated on my website):

We're trying to implement steps-without-JavaScript for slides. You can
get the module here:
http://cfd.homelinux.org/tex/
The current problem, in its simplest form, is that using \mframed breaks
the spacing. Minimal example:
\starttext
We aim to get this spacing:
\startformula
a + b
\stopformula
but when using:
\startformula
a \mframed{+ b}
\stopformula
we get the same broken spacing as in:
\startformula
a {+ b}
\stopformula
\stoptext
eh ... are you redefining low level macros?
I'd never dare to... ;-) Just overriding \placeformula within
\begingroup/\endgroup to mangle the formula numbers.
Thank you,
David

Thanks for the details. Indeed I get now what is expected from your

If I can suggest a possible improvement to the t-rsteps.tex macros,
it is the following:
When one uses these macros with an automatic numbering such as
\placeformula[equation-reference] (see the example below), with each
invocation of \page (that is a step) the number increases, and this
is an unwanted side result. Would it possible to freeze the
numbering procedure in such a way that the number doesn't change in
each step? (When I was using my macros, I didn't use \placeformula in
sildes with steps, but rather an old \leqno from plain TeX).

I tried also the short example I sent you today,
but I get the same result. Is there a
transmission error in your file? (I should say
that everything is fine if one doesn't have a
\placeformula).
Finally, if I am not being too demanding, at the
end of t-rsteps.tex, in your example of how to
use the command (for the user's convenience)
could you please incude all the possibilities of
using the Step commands? that is instances of:
\OnlyStep[1]{\item something}
\FromStep[2]{\item something}
\AfterStep[3]{\item something}
\UntilStep[4]{\item something}
\HighlightStep[5]{\item something}
\NextStep[1]{\item something}
(Actually it seems that there is also a problem with \NextStep)

You doesn't define a step mode, so there's no output.
Completely logical. What's the matter?
You can use --mode=something switch only for environments like
\startmode[something]
\stopmode[something]
\startnotmode[something]
\stopnotmode[something]

But probably you're looking for:

another option is to use s-pre-60

Re: [NTG-context] \presentationstep
Nothing seems to work here. I'm afraid the problem is indeed that
Acrobat Reader under Linux is not really JavaScript aware...
Would it be possible to implement the steps commands such that steps
span over multiple slides instead of being managed by JavaScript?

Would it be possible to implement the steps commands such that steps span over multiple slides instead of being managed by JavaScript? David I aggree with David that having the ConTeXt presentation feature without needed javascript would realy be great. Pdf is a standard, but not javascript. It's realy nice to come to a seminar only with a pdf file without worrying about which pdf reader tool exists on the host computer. - Even with acroread 6.02 on osx there is some problem with some button (I don't remember which problem, but I just remember it's not reliable); - Also Preview, the fastest pdf reader on osx (provide by Apple, then the it is standard pdf reader on osx) don't support javascript; - linux doesn't have pdf+javascript reader. So I think that ConTeXt should provide a mean (option in textexec) to make pdf-only version of presentation. Finaly there could be three output levels for pdf presentation : 1 - presentation step using javascript (with allow blinking, merging, zooming or other nice flashing features ;-) 2 - presentation step without javascript (one pdf page by step) = Good format for presentation by foreign pdf reader 3 - pdf file one pdf page for each final step by page = Good format for printing 2up or 4up slides This third output would also allow to print a slide + comment version of the presentation for the speacker. The option of texexec could be something like --pdfonly instead of --pdf, or simply --use-javascript=false Maurice, ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

[NTG-context] Presentationstep in pre-fuzzy
Hi, I have tried every combination of presentationstep and the NextStep button in pre-fuzzy presentation style, and nothing seems to work. I have the latest (ConTeXt ver: 2003.9.25 fmt: 2003.9.26 int: english mes: english) running on Mac OS X (10.2.8) with Gierben Wierda's teTex distribution. Can some one help me get presentationstep working in pre-fuzzy? Thanks, --shiv-- ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context
