[NTG-context] Weird Fieldstack problem
Hi,
I've written the following test file:
==
\setupcolors[state=start]
\setuppagenumbering[state=stop]
\setupinteraction [state=start]
\starttext
\MPdrawingdonetrue
\startMPdrawing
draw (0,0)--(2cm,2cm);
\stopMPdrawing
\definesymbol[aa][\getMPdrawing]
\startMPdrawing
draw (2cm,2cm)--(2cm,0);
\stopMPdrawing
\definesymbol[bb][\getMPdrawing]
\startMPdrawing
draw (0,0)--(2cm,0);
\stopMPdrawing
\definesymbol[cc][\getMPdrawing]
\definefieldstack[somemap][aa,bb,cc][height=fit,width=fit,frame=on]
\fieldstack[somemap]
\goto{here} [JS(Walk_Field{somemap})]
\stoptext
==
It seems that the fieldstack does not work. Is there anything wrong?

[NTG-context] code weaving (solved)

[NTG-context] \loadcurrentMPgraphic from metafun manual
Hi,
I have tried the following example (metafun-p.pdf, p. 112-3):
\startMPgraphic
draw unitsquare xscaled 5cm yscaled 1cm withpen pencircle scaled 2mm
withcolor .625red;
\stopMPgraphic
\hbox \bgroup
\loadcurrentMPgraphic{width=5cm,height=1cm}\placeMPgraphic \quad
\loadcurrentMPgraphic{width=8cm,height=1cm}\placeMPgraphic \egroup
but nothing is drawn unless I remove the setups in curly braces (in
which case a rectangle 5cm x 1cm is drawn). Is there a different way to
pass options to the figure inclusion macro?

[NTG-context] code weaving
Hi,
my footnotes are nicely defined a such:
\def\setnotebodyfont
{\let\setnotebodyfont\relax
\restoreglobalbodyfont
\switchtobodyfont[rm,9pt]\setupinterlinespace[line=9.8pt,height=.79,depth=.21]\parskip2pt}%
Now I have to set the entire text with hanging/hz – same for the footnotes.
But the related command ...
\setupfootnotes[align={block,hanging,hz}]
... is kind of overwritten/ignored by the syntax shown above. No matter where I
place it.
Could someone please show me how to weave the align-instructions into the given
footnote definition?
Thank you,
Steffen

I haven't tested this, but I think that all elements in the fieldstack
should have the same bounding box. Look at the widget manual, where
Hans shows how to make sure that all elements have the same bounding
box.

Re: [NTG-context] Weird Fieldstack problem
Hi Aditya,
Actually, they should have the same boundingbox, the first MPdrawing
environment draws a line from (0,0) to (2cm,2cm) and the sequence MPdrawing
environments just add two lines that are in the previous boundingbox.
I know what's happening now. \definesymbol doesn't define a symbol
from \getMPdrawing at once.

Hi Aditya,

I know what's happening now. \definesymbol doesn't define a symbol
from \getMPdrawing at once.
Yes, \definesymbol[a][b] is roughly equal to \def\a{b}, for example
\starttext
\def\something{aa}
\definesymbol[aa][\something]
\symbol[aa]
\def\something{bb}
\symbol[aa]
\stoptext
This is what is also happening in your case. You need to go back to the
definebuffer and processbuffer as suggested in metafun manual.
I do not know if it makes sense to have a \edef version of
definesymbol. In any case, getting expansion to work with \getMPdrawing
is going to be difficult.

Interestingwhat is happening is something equivalent to
\externalfigure
[\MPgraphicfile.\the\currentMPgraphic]
[type=mps,object=no,
symbol=yes,reset=yes,
maxwidth=,maxheight=,
frame=off,background=,
width=8cm,
height=1cm]%
and there is no figure. If I remove object=no, the figure is there. I
do not understand why object=no should affect the placement of the
figure.
