[NTG-context] Alter text to "Figure"

[Procházka Lukáš Ing .]

Hello,

how to alter auto-text to figures placed by 
"\placefloat[]{Caption}{\externalfigure[]}" to be:

"Figure 1.  Caption"

instead of

"Figure 1  Caption",

IOW, how to add "." after the figure "auto-text"?

Best regards,

Lukas

Re: [NTG-context] which command would give the same effect as \pause in beamer ?

[Otared Kavian]

Dear Mohammad Hossein,

Thank you for sharing this rawsteps-mkiv code: it works very smoothly and 
nicely: I haven’t done yet a real life presentation with it, but on your 
examples and a few other simple ones, your code works very well.

Best regards: OK

Re: [NTG-context] which command would give the same effect as \pause in beamer ?

[Mohammad Hossein Bateni]

I once ported RawSteps to MkIV but have not touched it in a while (and
probably won't have time to anytime soon).  Ten months ago, it used to work
almost fine.

Re: [NTG-context] Formula numbering conversion

[Antoine Cailliau]

I try to replicate the following :
https://mailman.ntg.nl/pipermail/ntg-context/2006/021038.html (i.e. the
equivalent of \tag in latex/amsmath). More precisely this:

> %8<--
> \def\placeformulatag%
>{\dosingleempty\doplaceformulatag}
> \def\doplaceformulatag[#1]#2%
>{\let\normalstopformula\stopformula
> \def\stopformula%
>  {\normalstopformula
>   \restorenumber[formula]
>   \egroup
>   \let\stopformula\normalstopformula}
>   \bgroup
>   \savenumber[formula]
>   \def\dummyconversion##1{#2}
>   \defineconversion[dummyconversion][\dummyconversion]
>   \setupformulas[conversion=dummyconversion]
>   \placeformula[#1]}
>
> \starttext
> \placeformulatag[tag]{test} \startformula
>E = mc^2
> \stopformula
> See \in formula[tag] for a tagged formula
> \stoptext
> %8<-


However, the following (simpler) code produce an "Undefined control
sequence" when using \in command.

\starttext
> {
>   \def\a#1{test}
>   \defineconversion[a][\a]
>   \setupformulae[numberconversion=a]
>   \placeformula[test]
>   \startformula E = mc^2 \stopformula
> }
> This is my reference: \in{formula}[test].
> \stoptext


The following code, does not produce the error, but is not practical for
the reproducing the \tag command.

What am I doing wrong? I guess the command \a is no longer defined when the
compiler hit \in but how can I ensure that such local definition stay
accessible ?

Thank you in advance,

Re: [NTG-context] which command would give the same effect as \pause in beamer ?

[Otared Kavian]

Hi,

If you use mkii you can still use RawSteps, but in mkiv it does not work 
properly and should be rewritten. 
However, as Hans indicates, one can use \startsetp and friends, as shown in the 
example presentations found in your directory
texmf/doc/context/presentations

Best regrads: OK

Hi Antoine,

it’s numberconversion (as it reads in “ConTeXt Commands”):

\setupformulas[numberconversion=greek]
\setupbodyfont[dejavu]
\starttext
\placeformula[test]
\startformula E = mc^2 \stopformula
\stoptext

BTW, if this is wrong documented in the wiki, please correct it for
future reference.

[NTG-context] Formula numbering conversion

[Antoine Cailliau]

The following code is documented to change the numbering of the equations.

However, this still use numerals for the equations.

\setupformulas[conversion=characters]

\starttext

\placeformula[test]
\startformula E = mc^2 \stopformula

\stoptext

Is this a bug ? Is it the correct way to change the numbering ?

Any help is welcome. Thank you in advance,

I read about \starthiding and \stophiding in the manual, but as far as I 
understand, this is not exactly what I am looking for.
I don't think postponing would help either.

Any suggestion will be welcome. I am using texlive 2015 version (nothing newer 
is available yet in OpenBSD).
Have a nice day,


texmf/doc/context/presentations

has examples ... you can have steps (pre-stepwise)

[NTG-context] which command would give the same effect as \pause in beamer ?

[damien]

Hello,


I have been switching to conTEXt to prepare some of my teaching stuff. I have 
read the context ref manual, the wiki and browsed the web, but couldn't find 
anything related to so-called overlays in beamer (I justed greped mail archives 
for 2015–2017).
What would be the conTEXt way to have a list or whatever else displayed in a 
slide in such a way that point 2 is hidden until you press space, and so on.
In beamer, you would make it this way

\begin{frame}
   \begin{itemize}
  \item 1 
  \pause
  \item 2
  \pause
 \item 3
\end{frame} 

Or even better, 

\begin{frame}
   \begin{itemize}[<+->]
  \item 1 
  \item 2
 \item 3
\end{frame} 

I read about \starthiding and \stophiding in the manual, but as far as I 
understand, this is not exactly what I am looking for.
I don't think postponing would help either.

Any suggestion will be welcome. I am using texlive 2015 version (nothing newer 
is available yet in OpenBSD). 
Have a nice day,


Damien Thiriet
