[NTG-context] metafun question
it seems that metafun has difficulty understanding the example using
thevardef [EMAIL PROTECTED] expr p = construct.
! Illegal parameter number in definition of [EMAIL PROTECTED]@dummy2.

argument ... p of p enddef; \par vardef [EMAIL PROTECTED]
expr p = cuta(@##,@##) @##...
\dostartuseMPgraphic ...leuseMPgraphic {#1}{#2}{#3

why?
i copied the sample of the mp manual:

[NTG-context] metafun question getting XY
if i define a path q := (w0,w0)--(w0,ww0)--(w2,ww1)--(w3,ww2)--(w3,w0)--cycle ; and then pass this path as a parameter to a function test( q ) ; then within that function i can step through the 'list of points'. def test( expr a ) = for i = 1 upto (length(a)-2): dotlabel.bot ( , (point i of a) ); endfor ; enddef; but how could i extract from each point the X and the Y value to construct the lines like this. for i = 1 upto (length(a)-2): z1 = (point i of a) ; draw (0,y1)--(100,y1) ; endfor; thanks! % floris ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

Hi Hans,
I attach an example Context file and the included graphics.
Unfortunately the example is by far not minimal.
The file is just a few bytes, no need to mention...
Just looking at the error message, I bet your problem is at:
\setupheadertexts[text][{\tfc 8}{\tfb-3\_refkom}][]
\setupheadertexts[margin][{\tfc bu}][\ifnum\pageno =

\symbol[PfeilNachRechts]}\else\PrevOrNextPage{/NextPage}{§

Hi Patrick,
i do not think that the problem is caused by the header texts. The same
header text definition is used during all the document but the problem
is encountered only at a page with several external figures. In
addition, if I insert a new page in between the figures then the problem
disappears (cf. original bug report).

[NTG-context] How to implement a changing navigation bar?
Hi all,
I use an overlay to implement a navigation bar in the left margin of a
document. It seems to me that the processing of the overlay is done only
once and not for every page again. In addition, the \lastpage is not
available.
Does anyone know a solution? Maybe headers/footers are a solution. But
how is absolute positioning accomplished with them?
Thanks for your attention,
--Stefan
PS: Here is my current implementation:
\definelayer[navbar]
\setupbackgrounds[text][leftmargin][background=navbar]
\setlayer[navbar][x=0cm,y=10cm]{\the\pageno}

[NTG-context] Using ConTeXt through MikTeX
Hello, friends, I posted this message some days back to the MikTeX mailing list, but would like to repeat it here. I use MikTeX with the text editor TechnicCenter. I generally work with PDFLaTeX. I have been reading about ConTeXt, which among other things enables the use of Metapost from within the package. (I wish to use Metapost as I need to draw lots of diagrams for Euclidean geometry.) It seems that one can configure MikTeX for ConTeXt. Could any user of ConTeXt suggest how to do the configuring? I am not able to act on the tips given. I have located in MikTeX Options the option cont-uk (in the Formats tab) and have selected it; but am not sure of the next step. I would be grateful for some advice on this matter. Thanks. Sincerely, Shailesh Shirali ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

OOPS! Sorry about this one. Couldn't see the hsize instead of \hsize
