Presentation help

Presentation help

[Adam Duck]

So, I showed ConTeXt to a friend of mine.  He said he wanted to try it
and now -- well, you don't want to know how he swears :).  We're
trying to do a presentation...

Anyways, I'm trying to help him...  But I (we) have some problems:

I managed to write something like this (it's never been so hard to
write a newline!):

#v+
\startsetups{myhead}
\vbox{%
\getmarking[sectionnumber]\crlf\getmarking[section]\par
\hskip12pt\getmarking[subsectionnumber]\crlf\getmarking[subsection]}
\stopsetups

\setupheadertexts[]
\setupheadertexts[\setups{myhead}][pagenumber]
#v-

That does, what it should: display section and subsection atop of each
other.  So, but now, he wants to have an "Introduction", which should
show up in the header but without a number.  I tried "\subject" but
"\getmarking[section]" only returns the section, not the subject (I
thought they were interlinked somehow, but...).  So, is there any way
to do this apart from "\ifx\getmarking[sectionnumber]{-1}" or so?


Next question: is it possbible to align the text of, well, "text",
i.e. the body text, vertically centered on every page?
"\setupbackgrounds" won't work here.  On a side note: why does it have
an align-parameter, then?


This one is "a bonus" for me: can someone point me in a direction
where to start to build a "progress meter"?  beamerstyle has a nice
template where it shows the section as text and the subsections as
open dots (all of them) with the current subsection as a filled dot.

Well, that would be all, thanks for listening,

Adam.

\startfrontmatter

\section{...}

\stopfrontmatter

will provide a mark but not number; so ... provide extra structure

because it inherits from \framed

\setupmakeup[standard][headerstate=start,align=middle]

\startstandardmakeup
\input tufte
\stopstandardmakeup

Thanks, all works out nicely.  So, I have another problem.  According
to my friend, every good presentation should highlight the current
section in the table of contents.  So I defined this:

#v+
\def\mycontext#1{%
\edef\stringa{\fetchmark[section][current]}
\edef\stringb{#1}
\strut
\ifx\stringa\stringb
\color[red]{#1}
\else
#1
\fi
}
#v-

This works with

\mycontext{a subject}

and even

\mycontext{\fetchmark[section][current]}

but doesn't work with placelist[section] with this setup:

#v+
\setuplist[section][criterium=all,
symbol=none,
numbercommand=$\bullet$,
textcommand=\mycontext,
pagenumber=no,
width=\baselineskip]
#v-

I think it's because textcommand gets more then just the text as
parameter.  But there is no deeptextcommand in setuplist.

cu, Adam.

Yes, it turns out, this was somehow my fault.  I had spaces in my
section titles, and somehow this doesn't turn out right.  Anyways,
with this command:

#v+
\def\mycontext#1{
\edef\stringa{\ignorespaces\fetchmark[section][current]}
\edef\stringb{\ignorespaces#1}
\strut\ifx\stringa\stringb
\color[red]{#1}
\else
#1
\fi}
#v-

I get it right even with spaces in them.  But this doesn't work if I
have an exclamation mark in a section title -- I don't say it's a good
idea to have an exclamation mark in the section title, but...  Is
there any way to solve this?

cu, Adam.
