[NTG-context] symbol parameter of \setuplist

[David Munger]

Hello,

I fear I cannot figure out what is the meaning of the `symbol' parameter
of \setuplist. From all the documentation or mailing list archives, the
only use I can find is "symbol=1".

Is there a way to use it to draw bullets, say, before each list item,
like those in the itemize environment? If not, what would be the best
way of achieving this? With \placelist[command=...] maybe?

Regards,

David

[NTG-context] Page number in interaction menu

[David Munger]

Hello,

Is there a way to remove the page number from the interaction menu? I
might be doing something wrong. Thanks for any clue.

Minimal example:

\setuppapersize [S6][S6]
\setuplayout [height=300pt, bottom=24pt]
\setupbodyfont [20pt]

\setupinteraction [state=start, menu=on]
\startinteractionmenu [bottom]
  Menu: \placelist[chapter]
[alternative=bottom,criterium=all,pagenumber=no]
\stopinteractionmenu

\starttext
\chapter{First}
\page hello
\chapter{Second}
\stoptext


Regards,

David

Hello,


Both of these fail (the second one is assumed to be unicode).

\hbox to \textwidth {\stretched{pr\'edoctoral}}
\hbox to \textwidth {\stretched{prÃdoctoral}}

Re: [NTG-context] Font encoding: \uppercased: \WORD

[David Wooten]

I came across the command \WORD{} in the manual (nice place to look, eh?). This does all capitals (it can be more than one word) and doesn't have the issue with diacritics that \uppercased was having for me. 

Thanks,
David

For example, with \uppercased{Krübel} I receive: KRüBEL. 

Do I need to "make a statement of my intent" in a typescript file or somewhere else to resolve this?

Re: [NTG-context] Font encoding: \uppercased

[David Wooten]

Greetings Vit, all,
Thanks for the response.
I'm finally getting around to looking into this again. My first 
attempts haven't yielded any good results. Could you (or someone) say a 
little more (newbie-explicit)? I assume that the enco-*.tex files 
you're referring to are in .../context/base/, where there are a series 
of 30 or so such files. It isn't clear to me which one to use. Does the 
encoding refer to font encoding? —in which case there is no 
"enco-8r.tex"— or to something else? — enco-pdf.tex for example.

Thanks very much,
David Wooten

Yes, \uccode and \lccode are encoding-dependent and are defined in 
enco-*.tex files. So, look into the encoding file you are using and 
add the their definition between
  \startmapping[st1]
\definecasemap 152 184 152
  \stopmapping
with meaning: character 152 has lower counterpart 184 and upper one 
152 (152 is uppercase letter).

(or for continuous sequence there is abbreviation
  \definecasemaps 160 to 188 lc +32 uc 0
 with meaning:
  \definecasemap 160 182 160
  \definecasemap 161 183 161
  ...
  \definecasemap 188 220 188
)

\starttext

Some text to start it all off

\FLOWchart[place-st-low]

Now we want some text so that it looks like their is actually some
more text at the end.

\stoptext

[NTG-context] Charts

[David Waller]

Hello,
I am using the charts module as part of context to produce flowcharts
and I am having problems when the flowchart goes above a page in that
I can't get the system to automatically split the chart.
I have the following setup commands in my context file

\usemodule[chart]
\setupFLOWcharts[maxwidth=\textwidth, nx=4]
\setupFLOWsplit[ny=9, before=, after=\page]

based upon the manual. I then use the command
\FLOWcharts [bigchart]

later in the document and the flowchart does not split, instead it
runs off the bottom of the page. I have also tried using \splitfloat
with no success either.

I am running
 TeXExec 5.2.5 - ConTeXt / PRAGMA ADE 1997-2005

Kpathsea released!

[NTG-context] \newbibfield[help!] : Very quick question.

[David Wooten]

Greetings all,
In working with the bib module, I've been trying to understand the 
addition of a field. There is a "\newbibfield" command, but it is not 
entirely clear where to declare it. E.g., I want to have a field called 
"yearnote". If I place this in the list of commands in the t-bib.tex 
file, and call for it with "\insertyearnote" in the 
\setuppublicationlayout, it works perfectly. But declaring 
\newbibfield[yearnote] yields me an "undefined control sequence". Is 
there a special place to declare the latter? — I've tried in my current 
file, before and after \starttext, in the .bbl file, before and after 
\setuppublicationlist… no luck!

David

Gerben,
I am so happy I can contribute as a way of thanking you for all the

[NTG-context] Font encoding: \uppercased

[David Wooten]

Greetings all,

Taco mentioned the command \uppercased{to get all uppercase letters}, and it works just fine…until I try to use my self-installed fonts. The quirks come up with diacritics, and this leads me to believe that there is an [encoding] or [regime] issue here, as I had similar issues earlier with the font in general. For example, with \uppercased{Krübel} I receive: KRüBEL. 

Do I need to "make a statement of my intent" in a typescript file or somewhere else to resolve this?

Kind regards,
David___

Re: [NTG-context] bib: potential range of bibliography styles?

[David Wooten]

Great, that does the trick. Another quickie:

This bib style demands that the first author/editor is "invertedauthor", while the subsequent authors/editors are "normalauthor", e.g.:

WOOTEN, David and Charles M. SCHULZ and Kris KRINGLE.
2005.  Adventures in Babysitting, etc.

Is there currently the possibility of distinguishing between the first & subsequent authors? (From my preliminary investigations it looks like all authors automatically follow the declared style.)

Regards,
David

P.S. This is a lot more fun than preparing for my exams!

Hello David,
To obviate figure numbers use the setupcaptions command, e.g.
\setupcaptions [number=no]
You can find a complete description of the command with texshow web on 
the ConTeXt wiki: <http://texshow.contextgarden.net>, or on page 224 
of the context manual.

I believe so. An example from the typescript file:

Ah-ha.
ConTeXt isn't *that* clever about names. At the end of the font synonym
chain, you need to associate the font name with an encoding explicitly.
The typescript names are just symbols (for the most part) that signal 
to
ConTeXt which groups of definitions to use.

Therefore, the above line should be:
 \definefontsynonym [Andulka-Book] [8r-andulkabook] [encoding=8r]
Bravo, that does it. Many thanks, Adam.

Hi David,
I took a look at your file (off-list), and it looks like you're using 
the
8r encoding. Interesting that you bring the "eth" up, because that
character doesn't exist in the 8r encoding.
Yes, that's my error—let's change that to thorn :)
8r encoding it is.
The result of something like \"a (or \"{a}) is _a_ without the
diacritic.

Curiously (to me, at least:), if I enter the actual glyph:
ä, it gives me the character I need…but only for a few runs!
Okay, that now becomes an interaction between regime (input file
encoding) and the rest. It could be coincidence that ä is in the same
slot (228) with both regime and encoding. Which regime are you using? 
Are
you sure it lines up with the encoding in (say) TeXshop?
I use TextMate for the text editing, and it's currently saving in 
UTF-8. …this area of "regime and encoding" isn't very clear to me. That 
sounds like a clue.

Some trials evince an ff-ligature as the diacritic.
That's another data point pointing to the encoding not being in synch.
So. More input required, but right now I'm eyeing the encoding with 
suspicion.

P.S. As a side point, Andulka does indeed look like a nice, sturdy,
legible text font. A bit like the free (but masterfully drawn) Charter,
but with a lot more personality.
Yes, I've grown fond of it, especially at a smaller size. Funny you 
should mention Charter in this regard, as it always had a certain 
appeal.

Greetings ConTeXters
I'm back to ask another question:
After an initial successful installation of the purchased fonts, I've 
come to find that there is a serious quirk. That is, when I try to use 
any special glyph, be it an accented character of any kind, or e.g. an 
eth. The result of something like \"a (or \"{a}) is _a_ without the 
diacritic. Curiously (to me, at least:), if I enter the actual glyph: 
ä, it gives me the character I need…but only for a few runs! After 
adding a couple more of such "alternative" glyphs, it starts to show 
gibberish. Some trials evince an ff-ligature as the diacritic. Errors 
in the mapping/virtual font/…?

Again I hope to save myself some time by asking to be pointed in the 
right direction, as my initial searches haven't really helped.

Only a couple things to add:
When fondu generates the .pfb file, copy the .afm to share the new

Texfont on MacOSX trips on capital letter extensions: make sure they're
uniformly lower case.
If fondu fails you (it hasn't failed me yet), there's also t1unmac 
(lcdf.org).

And if texfont installation fails or inexplicably stalls, you might 
need
to go in and truncate long (255+ character) lines by manually editing 
the
text file. I've always found these to be comment/copyright lines, so
you're not hurting anything by doing so.

Hello,

quick and dirty way may be \setupbodyfont[csr] in the document.

Systematically, my (older) cont-cz.tex contains
\setupbodyfont [csr,ams,rm,12pt]
What does your cont-cz.tex set?

[NTG-context] Initial Font Installation Question (Mac)

[David Wooten]

Greetings all,
I've been having a lot of fun struggling with the installation of a 
newly purchased font, and wanted to double check a preliminary question 
before I give in and ask a more thorough question ;)

I'm working with Mac OS X, so I bought a font-set with both Mac TTF and 
Postscript files. The Postscript folders have 2 types of file for each 
fontname: .afm and another without a suffix. The names also have 
uppercase letters, such as AndulBooBol (a.k.a. Andulka Book Bold).

For the texfont script, it apparently needs the .afm files and .pfb 
files. Thus:

1) Are these non-suffixed files the .pfb files in question? If so, 
should I rename (add .pfb to) them before trying to install them? (I 
could convert the TTF files to .pfb?)

2) Should I take away the UpperCaseLettering as well? Rename them to 
something more Berry-like?

In fact, I've tried these things with no success, but before I spell 
out the details of my failure I thought I would get this straight.

Kind regards,

[NTG-context] bib module: \cite with page numbers

[David Munger]

Hello,

Is it possible to get page numbers (or a chapter number) displayed in a
citation, e.g.

\cite[authoryears]{pp. 163-170}[davidson2001]

and

see \cite[authoryear]{chap. 3}[davidson2001]

would format as:

(Davidson, 2001, pp. 163-170)

and

see Davidson (2001) chap. 3


Thanks for any clue,

David

Re: [NTG-context] Tex-Live bittorrent sites?

[K. David Prince]

If you want to try a bittorrent download, you have to have a client that 
runs on your O/S.  A good one to try is to download the current Knoppix 
ISO image.  It is by far an excellent way to share large files AND 
"server" load.  In this case, the "server" is all the other machines that 
have bits of the file you're downloading (and uploading).  I usually let 
it run until I've uploaded at least as much as I've downloaded.  Your 
client will show you the up/down load statistics real time.  -kdp

Not that I am aware of.  If you find one or can set one up, please email
[EMAIL PROTECTED] with the info.
For those who may not know -- Hans just asked me :) -- BitTorrent is a
peer-to-peer system that lets big files be downloaded in small pieces
from many different machines.  The client reassembles the pieces.  I
haven't used it myself, although I've heard some good things about it.

[NTG-context] Displayed math--vertical space

[David Antos]

Hello,

I started to typeset real math in ConTeXt :-) and the following issue
occurred in vertical positioning. I know about start/stopformula,
nevertheless I suppose that good old $$ should work, too.

\starttext
A short line followed by a formula
$$\bigcup_{1\le n}$$
a text follows in the same paragraph. The big cup is too
close to the text.

If a displayed formula has enough text above
$$\bigcup_{1\le n}$$
the problem does not appear at all. The vertical space around the formula
is very nice here.

The only difference is whether the line above the formula goes more to the
right than the beginning the formula.

\stoptext

Thanks,
D.A.

Hello,

just a comment. In TeXlive2003, czhyph.tex contains first

\ifx\addlanguage\undefined
  \errmessage{This file can be used only in babelised formats!}
\fi

to test if the format is babelised. If the test succeeds it just reads
czhyphen.tex. I asked Petr Olsak either to remove this stupid test from
that file or to add a test for ConTeXt. We prepared a hack that I tried
to propagate into TeXlive, but after asking several times on texlive
mailing list I gave up. After reading a discussion on LaTeX Czech
support (and its backwards compatibility) in the CSTUG mailing list, I
like ConTeXt way of multilanguage support even more :-)

The path of least resistence is probably to make cont-usr.tex to point
directly to the actual position of czhyphen.tex directly :-(, sigh...

Yours,
D.A.

Hello,

don't worry, that is not the point. What I wanted is to include all
bibliographies cited in the work, not just the current chapter (which is
empty if you have a separate "bibliography chapter").

It has nothing to do with choosing the entries from .bib file. This
should include cited entries only and all entries as an option (as we're

sorry, I don't follow you :-(. What I'm saying is that alternatives a,

I expect this to expand to the macros you've cited in the end, so I
expect that

OK, how should this help? I've tried all of them in the setup (with

error and has no effect, though.

Hello,

thanks, nevertheless, more things seem to be broken with lists now.

I often use
\setupcombinedlist
  [content]
  [alternative=c]

It should (and used to) produce a list with dot leaders between names
and page numbers. It doesn't in the last stable. (I've tried to look
into core-lst, but it's too complicated for me :-)

Alternatives a, b, and c produce number-title-spaces-pagenumber,
d, e, f, and g seem to be correct.

Can you please have a look?

\placepublications with ConTeXt 2004.12.17 (last stable) and/or latest
beta.

The workaround is to use
\setuplist[pubs][criterium=all]
somewhere in the setup.

Can you please make including the whole bibliography make the default?
I'm pretty sure that's what everybody expects :-)

Thanks,
D.A.

Hmm... It seemed to work at first, but it just moved the problem. Now
it's (\sum) limits that are typeset like in inline style.

[NTG-context] At a loss how to proceed

[David Arnold]

All,

Lately, I've had a number of discussions with the director of disabled
student services at our school regarding document preparation for the
visually impaired. As a result of these discussions, I am a bit lost as how
to proceed with the preparation of mathematics for the web and documents
for my course content.

I've paid a little attention to the develoment of MathML, but I've always
said "Who wants to code like that?" whenever I look at examples. However,
today I found:

http://www.dessci.com/en/company/press/releases/040722.htm

I now realize that software that reads web pages aloud it pretty important.
But how do I, in my limited time, prepare documents for multiple purposes?
Can I use Context to support all of our students at our school? Just how do
I proceed?

At a loss.

Re: [NTG-context] Updated math modules

[David Munger]

Hello Giuseppe,

Thanks for your good work. Sorry for reminding this bug to you, but it's
the only reason why I can't use nath even though I wish a lot. About the
problem unicode characters in toc.

Ref.: http://www.ntg.nl/pipermail/ntg-context/2004/005306.html

I attached a minimal example unicode file. You'll get garbage instead of
the expected the "e acute" on the word "MathÃmatiques" in the table of
contents.

No matter wheter I use the amsl module or not, I get the following entry
in my tuo file:

\listentry{section}{1}{1}{Math^^c3^^a9matiques}{2::0:0:1:0:0:0:0::1}{1}


Moreover, if you replace [nath] with just [amsl], you'll get different
alignment of the formula.

BTW: my TeX doesn't seem to like DOS-style newlines in t-amsl.tex, so I
had to convert them to Unix-style ones.

You're a mathematician, aren't you :-) Have a look at

[NTG-context] Czech support (Was: Re: does context support vietnamese?)

Hello,

Hyphenation patterns work OK for Czech. Settings for Czech seem to be
reasonable (I'd only redefine subsentence setting and mainly date),
generated words (Chapter, ...) work fine, at least it is easy to
redefine them to one's personal taste :-)

System messages and names of macros are available in Czech (although I
cannot imagine anyone who would use them; things like "nastavramovani"
for setupframed seem really perverted to me:-).

Index sorting is missing in the distribution; in any case, Czech sorting
rules are really ugly and need incorporation of Cz::Sort into texutil. I
don't keep an eye on ConTeXt development very carefully so I might be
out-of-sync, nevertheless it'd be nice to have a sorting module
pluggable into texutil (just a suggestion).

The Czech support is based on master thesis of Tomas Hudec. After
finishing his study, he disappeared and I have no knowledge about him.
Fortunately, I have the complete sources of his work, so the missing
parts could be filled. I've prepared a Bc. thesis assignment saying in
fact "take Tomas' thesis and make it really work" but I haven't manage
anybody to do that :-(

Currently, I'm pretty busy (and use ConTeXt to write in English), so if
a Czech speaking ConTeXt user wants to have a look at it, I can send
him/her the archive.

D.A.

[NTG-context] \startexample

[David Arnold]

All,

I have this example I would like to typeset.

\startexample
Show that $0.\overline{621}$ is a rational number.
\stopexample

In this case, there are three digits under the repeating bar. If we
let $x=0.\overline{621}$, then multiply by 1000, we have

\startformula
\eqalign{1000x&=621.621621\dots\cr
  x&=\phantom{62}0.621621\dots.}
\stopformula

Subtracting,

\startformula
\eqalign{999x&=621\cr
x&={621\over 999}.}
\stopformula

Dividing numerator and denominator by 27 (or first by 9 then by 3), we
find that $0.\overline{621}=23/37$. Thus, $0.\overline{621}$, being
the ratio of two integers, is rational.

I have defined:

\defineenumeration
[example]
[location=serried,
  text=Example,
  before=\blank,
  after=\blank
  style=slanted]

What I would really like is an enumeration where only the example state is
in slanted type, then the solution follows (without an indent) in upright
(normal) font. At the end of the solution, I'd like a little symbol at the
lower right to indicate the end of the solution, then a little blank space
before continuing the narrative.

Can someone help me with this?

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.

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.

Good point! Here's the fix (file updated on my website):

37c37
<   \dodoubleempty\doplaceformula[##1]}
---
>   \dodoubleempty\doplaceformula}
50c50,54

Now we got rid of the duplicate label warnings. I also added your
contribution to the usage example. Thank you.

Re: [NTG-context] Tex or Context Editors.

[David Arnold]

Hans,

One of my favorite things about Auctex+Emacs is C-M-\ which will format
marked region, buffer, etc. The source coes is ually nicely aligned after
application of this macro.

Now, I've seen your source code over the years and it is quite beautiful,
easy to read.

Are you telling us that Scite will do alignment of tables and other nice
automatic formatting?

Hans, Matthias,

Thanks. Changing:

\startreusableMPgraphic{layout 1}

to

\startruseMPgraphic{layout 1}

fixed the problem.

Patrick,

Found it (t-layout) at http://levana.de/context/. Good stuff. Let me look
at this more carefully. This is definitely what is needed in any
introductory Context manual.

[NTG-context] More on compiling --- texmstart

[Arnold, David]

All,

OK, it seems the times are passing me by. I am running Miktex 2.4. It comes
with Context installed and there is a texexec.exe in /texmf/miktex/bin,
which is on my path. 

C:\CONTEXT\PRACTICE>path
PATH=C:\Perl\bin\;C:\texmf\miktex\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WIND
OWS\
System32\Wbem;c:\yandy\yandytex;c:\yandy\dviwind

After enabling write18 and setting these in my cont-sys.tex,

\runMPgraphicstrue
\runMPTEXgraphicstrue
\useMETAFUNformattrue

I could not get Context to build Metapost graphics on the fly (at least in
my test file).

I have installed Ruby. After reading:

http://www.contextgarden.net/Update_Hints

I tried the following:

texmfstart --make texexec.pl

This built a texexec.bat, which I moved to /texmf/miktex/bin, where I also
renamed texexec.exe to texexec.exe.bak. As a result, the file below compiled
nicely and I had my graphic in the background.

However, this killed Context running in Auctex and Emacs, which will no
longer compile the file below. I get the error message in the attached log
file.

Any thoughts on how I can get going in Auctex again?

Excellent idea indeed! Here's the fix. It is obviously not optimal,
though it allows for multiple formula numbers on the same slide. Try it
with:
texexec --pdf --mode=demo t-rsteps

Thanks for your advice.

Oh sorry for not being clear about it. I was assuming that some
presentation module would be imported, for instance:
\usemodule[pre-original]

So probably there lacks a \page command in your \Subject definition.

About the \[ and \]: you're right. I was using the amsl module from
Giuseppe Bilotta.

Thanks for your remarks. :-)


So, assuming that the steps code is in a file name t-rsteps.tex, the
complete example would be:

--

\usemodule [pre-original]
\usemodule [rsteps]

\starttext
\StartSteps[Slide Title]   % the title is passed to
   % the \Subject macro

\startitemize
\item Item 1
\OnlyStep[2]  {\item (oops!)}
\UntilStep[4] {\item Item 2*}
\FromStep[4]  {\item Item 2}
\stopitemize

\StopSteps

\StartSteps[Navier||Stokes equation]

\startformula
  \frac{D\vec u}{Dt} =
\FromStep[2][reserve]{-{\red \frac1\rho \vec\nabla p}}
\FromStep[3][reserve]{+\;{\green \vec g}}
\FromStep[4][reserve]{+\;{\blue \frac1\rho \vec\nabla\cdot S}}

All,

This test file:

If I follow this procedure:

Then I get a nice document when opened in Acrobat Reader.

However, with the document below, this same procedure doesn't produce the

Re: [NTG-context] \presentationstep

[David Munger]

Hi all,

Inspiring from Otared Kavian's code and Han's presentation styles with
support for steps, I cooked the following in order to solve the non
JavaScript version issue. I post it in case it could be useful to other
people.

This implementation supports an \{Only|From|Until}Step[n] syntax as well
as the simple \NextStep-style one.

Otared: Any comments or suggestions?

And here is an example of usage:

---
\StartSteps[Slide Title]   % the title is passed to
   % the \Subject macro

\startitemize
\item Item 1
\OnlyStep[2]  {\item (oops!)}
\UntilStep[4] {\item Item 2*}
\FromStep[4]  {\item Item 2}
\stopitemize

\StopSteps
---

And here is a mixed example:

---
\StartSteps[Navier||Stokes equation]

\[
  \frac{D\vec u}{Dt} =
\FromStep[2][reserve]{-{\red \frac1\rho \vec\nabla p}}
\FromStep[3][reserve]{+\;{\green \vec g}}
\FromStep[4][reserve]{+\;{\blue \frac1\rho \div S}}
\]

Momentum transport: \NextStep
\item {\red   Pressure gradient}\par\NextStep
\item {\green Gravity}  \par\NextStep
\item {\blue  Stress (viscous, turbulent, Maxwell)}

\StopSteps
---

And here's the code:


% steps for slides

Well, I don't own a Lamport, and probably not many ConTeXt users own one, so
your description could be more verbose.

Nevertheless you might want to have a look at http://levana.de/context/
there is somewhere a module that should do something like this. But there is
still a bug in there when the margins are too small.

TeX encountered an unknown command name. You probably misspelled the
name. If this message occurs when a LaTeX command is being processed,
the command is probably in the wrong place---for example, the error
can be produced by an \item command that's not inside a list-making
environment. The error can also be caused by a missing \documentstyle
command.

Any ideas?

[NTG-context] s-pre-61

[Arnold, David]

Hans et al,

OK, s-pre-61 looks nice and the source is not too long. It looks like a good
place to start. So, I tried:

Texexec --pdf --mode=demo s-pre-61

I got:

(./type-spe.tex) (./type-exa.tex) (./type-akb.tex) (./type-ghz.tex)"makemf"

?

Now, I know this is related to a font, so I looked in the source and found:

\usetypescriptfile[type-ghz]
\definetypeface[mainface][ss][sans][optima-nova][default][encoding=\defaulte
ncoding]
\setupbodyfont[mainface,ss,18pt]
\setupinterlinespace[line=3.25ex]

Since I am trying to learn Context in some depth this go round, I'd like to
start by getting this font installed, if possible. What's the easiest way to
get this done?

[NTG-context] Override starttyping environment

[Arnold, David]

Hans et al,

I have in my preamble:

\definetyping[matlab]

\setuptyping[matlab]
[before={\startframedtext[width=\makeupwidth,
  background=screen,
  backgroundscreen=0.9]},
  after={\stopframedtext},
  color=darkred]

Later in my document, I tried to center one of these environments:

\startalignment[middle]
\switchtobodyfont[big]
\startmatlab
y = x.^2 -2*x - 3
\stopmatlab
\stopalignment

But it comes out left justified, not centered. 

Any ideas how I can center one of these environments, one time only?

[NTG-context] \setuplayout --- what do parameters mean?

[David Arnold]

All,

When I see something like this:

\setuplayout
  [topspace=10pt,
   header=40pt,
   headerdistance=20pt,
   height=middle,
   footerdistance=20pt,
   footer=0pt,
   bottomdistance=10pt,
   bottom=20pt,
   bottomspace=40pt,
   backspace=30pt,
   width=middle]

I have a hard time working out what it means. I know I can do \showframe,
but that doesn't indicate everything I need to see. Does anyone have a
macro that shows ALL of these parameters in a visual way, similar to that
on page 182 of the Latex User Guide, 2nd ed., Lamport?

Hi Otared,

Thanks a lot for you macros. They do the job pretty well. They remind me

how to Wiki your post. Thanks again!

This is actually what I tried.

I think the latest Acrobat Reader version for Linux is 5.0.9. I guess

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?

[David Arnold]

Hans, Patrick, et al,

This was my fault. I don't have Lucida fonts set up properly on my system
for Context (and I don't want to go there yet), so I just switched over to
Computer Modern and all is fine.
