[NTG-context] EuroTeX 2012 / 6th ConTeXt Meeting reminder

2012-08-20 Thread Taco Hoekwater

Hi all,

Invitation
==

This is a reminder that EuroTeX 2012, the sixth ConTeXt meeting, the
NTG najaarsbijeenkomst, and Dante's Herbsttagung will all be held
together at the same time and place in Breskens, the Netherlands, on

  October 8 - October 12

The organisation of the conference is a joint effort of the NTG, Dante
and the ConTeXt Group.

Theme
=

Breskens is a small beach town that lives mostly off tourism, and
people on vacation tend to do slightly odd, relaxing things that they
do not normally have time for. Combining these two, the motto of this
conference is:

  Recreational uses of TeX

We already have quite some interesting talks, but we are still
accepting new proposals.

Registering
===

Please note that registration will be possible until SEPTEMBER 10,
and that there can be no late registrations for this conference.
So if you wish to attend, you have only three weeks left to fill
in your registration!

See http://www.ntg.nl/eurotex2012/ for additional details, including
abstracts and the registration form.

The programme promises to be quite interesting, so we hope to see
you there!

On behalf of the organising committee,

Taco Hoekwater

PS Please forward this message to whoever seems appropriate to you.

[NTG-context] Problem with SETUPTEX and KSH93

2012-08-20 Thread Alessandro Perucchi

Hello,

I'm new to ConTeXt, and I find it great!

I've done the standalone installation on my Linux box. For many reasons, 
I don't use bash, but ksh since all my customers are using ksh as there 
shell.


Nevertheless, the setuptex is not working for me.
Of course it works if I say

. ~/context/tex/setuptex ~/context/tex

But I would like to have it in the short form:

. ~/context/tex/setuptex

So for that in ksh, I needed to correct the setuptex like that:

line 99:
if [ z$BASH_SOURCE != z ]; then
SCRIPTPATH=$BASH_SOURCE
else
if [ z${.sh.version} != z ]; then
SCRIPTPATH=${.sh.file}
else
SCRIPTPATH=$0
fi
fi

And now, it works for ksh93, and all the other shells should be unaffected.

Would it be possible to correct it? Or if someone has a better idea, 
then I'm also ok, as long as it works for ksh.


Sincerely yours,
Alessandro Perucchi

[NTG-context] Runtime Error (TeXLive and ConTeXt )

2012-08-20 Thread Hrothgar Boyce
TeXLive Version: 2012  (--all updated to August 20th, 2012)
Platform:  CYGWIN_NT-6.0 1.7.16(0.262/5/3) 2012-07-20 22:55
The attempted command which ends in an error is:

   texexec -o pdf 659-water-stations.tex

This results in: PANIC: unprotected error in call to Lua API
 (zlib library version does not match -
header: 1.2.5, library: 1.2.7)

However /usr/include/zlib.h  is for version 1.2.7, not the 1.2.5
mentioned in the error message. Any idea of how to fix this, so I
can run ConTexT?
Thanks for any and all help.

[NTG-context] test for (negative) number

2012-08-20 Thread Peter Rolf
Hi,

I used '\doifnumberelse' to validate some macro parameters (angle).
Sadly it does not work with negative numbers. Is there a similar macro,
that also supports negative values?

Example:

\doifnumberelse {45}{yes}{no}% yes
\doifnumberelse{-45}{yes}{no}% no


Greetings, Peter

[NTG-context] Stable versions of MkIV

2012-08-20 Thread Sietse Brouwer
Hi all,

The current stable MkIV, the MkIV on the wiki, and the MkIV in TeX
Live are quite different things.

MkIV 2011.005.18 -- result of first-setup.sh --current
MkIV 2011.10.008 -- version on the wiki
MkIV 2012.005.29 -- version in TeX Live 2012, AFAICT (Mojca?)

1. Why not declare the version in TeX Live to be stable? I know Mojca
puts some work into making it as bug-free as possible.

2. Perhaps have the MkIV on the wiki track the MkIV in TeXlive? We can
show off reasonably-recent features, it looks more up-to-date, it's a
nice clear answer to should we update already?, and it ensures that
we update to reasonably bug-free versions.

3. Is there a list of past stable versions somewhere? I can't find
one, and without it the ability to go to a specific stable version
with
`sh ./first-setup.sh --context=date` seems a bit useless. (Can't
really imagine a use in general, though.)

4. (Less important.) context.mkiv defines \contextversion as e.g.
`2012.08.11 14:11`, but \contextversionnumber in mult-ini.mkiv still
prepends a zero to the month or day. (It checks whether 08  10, which
is true even if the leading zero is present.) This causes the extra
zeros you saw in the version numbers above. Can this be changed
without breakage ensuing? I expect that nobody depends on it over the
more direct \contextversion. (People that do use \contextversionnumber
have a problem anyway, because the version strings it produces in
October-December will always turn out 'earlier/older' than the ones
produced in January-September, regardless of year.)

Cheers,
Sietse

Re: [NTG-context] test for (negative) number

2012-08-20 Thread Sietse Brouwer
Hi Peter,

I recommend using the following handy little idiom:
\ctxlua{commands.doifelse(-45  0)}{big}{small} % small

It lets you do all sorts of things that are tricky in TeX:
\ctxlua{ commands.doifelse( string.len( -45 )  5 ) }{long}{short}

Cheers,
Sietse

[NTG-context] How to know in which page I'm?

2012-08-20 Thread Xan

Hi,

I want to print a message depending if the page is even or odd. In 
pseudocode:


\if \inpage.\iseven {
  This page is even
}
\else {
  This page is odd
}

How can I do that in ConTeXt?

Thanks in advance,
Xan.

Hello Mojca,

thanks :-) it works wonderfully!
Now, I don't have to patch setuptex each time I'm updating ConTeXt :-D

Re: [NTG-context] Struggling with ConTeXt

2012-08-20 Thread Olivier Binda

Many thanks for the enlightening answers.

The explanations about xml solved question 1 and \startmatrix\stopmatrix 
solved question 4.


I'm now crunching xml input and handling it half in lua and half in tex 
(and I'm verry happy about it).


I'm still struggling with a few points though (with context standalone 
beta on ubuntu):


3) I'm flowing text around mathematical text with graphic ornaments 
(overlay) but the bounding box from metapost (red) and from TeX (black) 
on the following minimal example aren't the same which produce all kinds 
of flowing text issues.
is there a way/an option for framedtexts with overlay to get the max 
width/height size of the main content + overlays ?



\startusableMPgraphic{myFrame}
  numeric o, l, m ; path a, b ; pair c ;
  picture d; d = textext.rt(\MPstring{Content}) ;
  draw (unitsquare xyscaled (OverlayWidth,OverlayHeight) shifted 
(-OverlayWidth/2,-OverlayHeight/2)) withpen pencircle scaled 1pt 
withcolor green;

  draw (d enlarged 2cm) withcolor red withpen pencircle scaled 2pt;
   draw boundingbox currentpicture withpen pencircle scaled .1mm dashed 
evenly withcolor blue ;

\stopusableMPgraphic

\defineoverlay[myOverlay][\useMPgraphic{myFrame}]
\defineframedtext[myStatement][frame=off]
\setupframedtexts[myStatement][backgroundcolor=lightgray,background=myOverlay,width=\textwidth,autowidth=force]
\starttext
\framed[fit]{\startmyStatement
TEST
\stopmyStatement}
\stoptext


3b) I found a dirty workaround by making metapost draw the texts and the 
graphics (through mpstring) but then, i can't embed graphics in my 
Tex-text.

Is there a way to have graphics inside MPstrings that goes inside metapost ?



About question 2, Context doesn't produce svg okey...but tikz and 
metapost can produce svg.
So, is there a ConteXt setup/systems calls/a  (simple or not) workaround 
to make metapost/tikz produce svg files ?

Like some script that I could run on my snipets ?

I would really like to produce svg from my metapost/tikz pictures



Best regards,
Olivier
