Re: [NTG-context] Bold in math mode

2006-07-12 Thread David Munger
David,

The method I use to get bold math is on the wiki:
http://wiki.contextgarden.net/Bold_Math
under Wrapping in a \hbox.

Then, to get a bold x, I would use $\boldsymbol{x}$.

 oh, I see. I'll admit: all the maths I've dealt with don't require such 
 fine manual control over the fonts.

Well, sometimes it's useful when dealing with different kinds of objects
such as vectors and tensors.

 Would it be for individual characters? Would an approach like this work?
 \formula{a, {\rm a}, {\bfm a}, \text{\bf a}}

Yes, of course. This happens to be an \hbox. My point is simply that we
have not come to a general solution yet, we are just finding different
workarounds to suit our personal needs, which is not bad indeed.

[NTG-context] Updated RawSteps module

2006-01-12 Thread David Munger
Hi all,

There have been many requests in the last few months regarding the
RawSteps module, but I had not much time to spend on it before the
holidays. Until Patrick updates the garden, you can grab the updated
module on my website:

http://mhd.selfip.info/tex/

The documentation is also updated on the wiki:

http://wiki.contextgarden.net/RawSteps


New features since 2005-04-11:
* New macro: \OnSteps (thanks to Taco Hoekwater)
* New macro: \StepsRegisterNumber as a numbering helper
* Bug fixes: section numbering, table of contents, and step  10.


Since I'm rather loosely monitoring the list, please CC me when
reporting bugs, or at least put RawSteps or rsteps as the first word
of the subject, so my email client doesn't hide it.


Best regards,

David

Re: [NTG-context] Re: function plotting

2005-10-05 Thread David Munger
 gnuplot is great indeed, but the output is rather large; it would be nice if 
 there was a real good output mode (say, comparable to the output produced by 
 metapost: compact, parsable); 
 
 btw, is it really that difficult to use gnuplot output in context? 
 
 Hans 

I often use metapost output from gnuplot indeed, then pass it through a
short sed script to do stuff like adding \start/stopuseMPgraphic
commands and cleaning the preamble. I think gnuplot does a great job in
general.

For more complex graphs, I prefer the mp-graph package.

Jilani,


 Thank you for your answer. I seems that \startformula .. \stopformula 
 doesn't have any effect to produce a dispaly mode formula.

When I try:

\startformula
  \mframed[offset=.3em,rulethickness=1pt]{
I=x-\sqrt2\,\arctan\frac{x}{\sqrt2}+C}
\stopformula

it does typeset a displayed formula. However, you could still force
displayed style by adding a \displaystyle command at the beginning of
your \mframed argument.

Re: [NTG-context] t-rsteps and starttyping

2005-09-22 Thread David Munger
Hans,

The RawSteps module produces virtual slides with stepping, by rendering
the step incrementally on successive pages. Thus, the
\StartSteps...\StopSteps macro has to expand its argument (i.e. the
content of the slide) a certain number of times, depending the number of
requested steps. Of course, it shows only the relevant parts at each
step.

To allow this, I had to work around page numbers, formula numbers, and
lately \starttyping blocks.

If you could suggest a better way to achieve this multiple expansion, it
would be welcome.

Regards,

David

 why exactly do you need this construct; there may be other ways to do it;

Hans Hagen:
 did you ever try 
 
   texexec --mode=demo s-pre-61 
 
 using 'layers' is rather robust (no duplicate pages and such); 

Of course, I did. The only issue is about JavaScript, which does not
work in most non-Acrobat PDF readers. This is the purpose of the
RawSteps module: to avoid using JavaScript.

 Some of the older presentation styles build the pages stepwise, they
 use either boxes, or buffers (i must look into it, but there is also
 one that plugs into the otr; in your case, collecting in a box and
 uncopying it is probably the best method.

Do you mean with \setbox-like commands? I'll have a look at it. Thanks

Re: [NTG-context] How to insert a full page pdf.

2005-04-19 Thread David Munger
Hi John,

John R. Culleton :
 I need to insert some example pages from one document into
 another. Both are 8.5 x 11. 
 
 I have read the old posts about \startTEXpage etc. and looked at
 the source code. But I still have a few questions:
 1. Can I select e.g., just page 2 from the external document to
 insert in my document? How?

I'm no expert, but here's the way I do it:

\externalfigure[filename][page=2]

Then, I adjust the clipping to -- for instance -- get rid of the page
number of the inserted `figure', as well as of its top and left margins.

\clip [ voffset=1.25in, % clip the topmost part of the inserted page
hoffset=1.5in,  % clip the left margin of the inserted page
height=9in, % clip the bottom of the inserted page
width=5.1in]% clip the right margin
  {\externalfigure[filename][page=2]}}

And, if you like, you can put all this into a \midaligned{}.


 2. Does Context automatically bump its page counter to compensate
 for the inserted page or pages, or do I have to adjust it after
 each such insertion?

Well, if you treat the inserted PDF page as a figure, the page number of
your main document won't be affected. Just clip the page number (if any)
which lies on the inserted PDF page.

David

Thanks for trying, but it is not the correct way. Sorry for being

texexec.

Hans,

 unless ( $dosish  ! $escapeshell ) {
  $cmd =~ s/[^\\]\/\\\/io ;
 }

The space before the  gets replaced by a \ so that cmd was:

... -int=batchmode cont-en

and becomes:

... -int=batchmode\cont-en


Maybe use:
$cmd =~ s/([^\\])\/$1\\\/io ;

Re: [NTG-context] Updated math modules

2004-11-22 Thread 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 Mathmatiques 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.

Otared Kavian wrote :
 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):

37c37
   \dodoubleempty\doplaceformula[##1]}
---
   \dodoubleempty\doplaceformula}
50c50,54
   \dodoubleempty\doplaceformula[1]}
---
   [EMAIL PROTECTED]@number%
 [EMAIL PROTECTED]
   \else

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

 I haven't followed the discussion so closely, what is the problem?

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

 Hi David,
 
 Thanks for the details. Indeed I get now what is expected from your 
 macros, and as a matter of fact the result is much much better than 
 that of my crude macros... You did a great improvement!
 So I am going to use yours from now on: thanks again!
 
 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).

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.

 \setuppapersize [S6][S6]

 Best regards: OK

Oh sorry for not being clear about it. I was assuming that some

\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

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)}

 s-pre-61.tex) I ended up
 writing a few macros which work fine with ConTeXt and the presentation modules.
 These macros are very elementary and crude, but they work...
 If I succeed to learn how to use layers smartly as does Hans, I will 
 write these macros again. :-)
 
 Below are the macros and some examples.
 Best regards: OK

[NTG-context] amsl: startcases/stopcases

Hello Giuseppe,
I'm having a little trouble with the cases in amsl.
Compiling this:
\[
 f(x) =

   0 \text{if $x  -\epsilon$} \\
   \frac12   \text{if $x   \epsilon$}
 \stopcases

results in an error around the \frac. Changing it to \dfrac makes the  
input compile ok, but typesets the cases in an ugly manner with really  
narrow spacing.

Is there some way of telling startcases/stopcases to behave in display  
mode?

[NTG-context] aligned equation numbers in nath

2004-02-23 Thread David Munger
Hi Giuseppe,

I know it's still work in progress, but could you suggest me some  
workaround in order to number individual aligned equations in nath?  
Maybe some \label command that would work like this way:

\[
 \startalign
   x^2 + y^2 = a^2
   \\
   \label[eq:bogus]
   a^2 = R^2
 \stopalign
\]
In \in{equation}[eq:bogus], blah blah
No matter wether the other aligned equations are numbered or not. All I  
wish is to be able to refer to a single equation.

Or maybe there is a way to set a kind of anchor?

\[
 x^2 + y^2 \setanchor= a^2
\]
\placeformula[eq:bogus]
\[
 a^2 \getanchor= R^2
\]
so that both equal signs be aligned. Something like this would be very  
nice.

Thanks in advance,

David

[NTG-context] boldsymbol workaround

2004-02-22 Thread David Munger
Hi all,

I've just found a little workaround for using boldsymbols. It works  
even with the nath module. It's probably not the best way of doing it,  
but since it does the trick for me, I guess it might useful to other  
ConTeXters.

Here it is:

\define[1]\boldsymbol{{\hbox{\formula{\bfm #1

I also have to:

\definebodyfont
 [17.3pt,14.4pt,12pt,11pt,10pt,9pt,8pt,7pt,6pt,5pt,4pt]
 [mm]
 [mrbf=cmbx10 sa 1,
  exbf=cmex10  sa 1,
  mibf=cmmib10 sa 1,
  sybf=cmbsy10 sa 1,
  mabf=msam10  sa 1]
\setupformulae[method=bold]

Then, I may define very handy commands like

\define\grad{\boldsymbol{\nabla}}
\define[1]\vec{\boldsymbol{#1}}
\define[1]\unitvec{\hat{\vec{#1}}}
and formulas like this typeset perfectly:

\[ \grad h = a \unitvec{n} \]

[NTG-context] bfmath in nath

Hello,

The following outputs a nice bold displayed omega (the first one), and  
a thin normal inline one (the second one):

\usemodule [nath]
\setupbodyfont [12pt]
\definebodyfont [12pt] [mm] [mibf=cmmib10 sa 1]

Note that replacing nath with amsl in \usemodule[nath] results in two

No.

How does psfrag from LaTeX work internally? Perhaps we are able to
make something similar.


I don't know how about its internals, but here's a usage example. For  
instance, using some vector graphics program, I write a text label alpha on  
some figure, and I print this figure in an EPS file. Then, using PSfrag, right  
before \including the EPS file, I tell PSfrag to replace alpha with $\alpha 
$:
\psfrag{alpha}{$\alpha$}
\includegraphics{some_eps_file}

I believe PSfrag works in conjunction with dvips. There's this PS file which  
may give you some clue:
texmf/dvips/psfrag/psfrag.pro
I can neither read TeX code nor PS code, but it is likely that it builds some  
sort of lookup table for the labels. If I can help anyway, please tell me.

There are those two other files:
texmf/tex/plain/graphics/psfrag.tex
texmf/tex/latex/misc/psfrag.sty
