Re: [NTG-context] Struggling with ConTeXt
Thank you for the tips.
Here, I cleaned up the code some more (sorry to have left stuff over
last time),.
I added some explanations to make my issue clearer
\startusableMPgraphic{myFrame}
draw OverlayBox withpen pencircle scaled 1pt withcolor green;
draw (currentpicture enlarged 2cm) withcolor red withpen pencircle
scaled 2pt;
\stopusableMPgraphic
\defineoverlay[myOverlay][\useMPgraphic{myFrame}]
\defineframedtext[myStatement][frame=off]
\setupframedtexts[myStatement][background=myOverlay,offset=overlay,autowidth=force]
\starttext
\framed[strut=no]{\startmyStatement FIRST TEST\stopmyStatement}
In the first test, I would like the black box to have the dimensions of
the red box.
\blank[big,big,big,big,big,big,big,big,big,big]
\placefigure[left,none]{}{\startmyStatement SECOND TEST\stopmyStatement}
In the second test, I'm going to demonstrate the issue by flowing text
around the framed text, the green color {\em and the red color}
shouldn't touch the flowing text as I want the float box to include the
text box {\em and the overlay box.}
Best regards,

Thanks for the help. But I'm affraid that this won't do as I won't
know/I am not supposed to know the dimensions of the bounding box of the
overlay I'll use.
:/
For the sake of the minimal example, I only enlarged the picture by 2cm,
but in real production situations,
the bounding box is going to be enlarged by random offset, because the
overlay will have various parts with weird shapes (super ellipse,
squeezed rectangles) that go beyond the original text boundaries (like
in the Zapf frametext example of the Context manual : the title is
protruding out of the main box and if you put weird stuff in there, you
won't know the dimensions).
I don't want to manually calculate those offsets, I would like metapost
to pass it's bounding box dimensions for the overlay to context so that
it automatically applies the correct offset to the text+overlay
]{\myStatement{SECOND TEST}}}
If needed, you can hide this behind macros:
\def\startmyStatement

Can you create a minimal example showing what you are trying to do? The

use framedtext instead of framed? What is \framed[fit] supposed to do?
etc).
\startusableMPgraphic{myFrame}

You could also use
draw OverlayBox withpen ...
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}]

\setupframedtexts[myStatement][backgroundcolor=lightgray,background=myOverlay,width=\textwidth,autowidth=force]
\starttext
\framed[fit]{\startmyStatement

\stopmyStatement}
\stoptext
You can try \framed[strut=no]{...} and add
\setupframedtext[...][offset=overlay]. See
http://wiki.contextgarden.net/Command/setupframed for details.

Re: [NTG-context] Struggling with ConTeXt
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

Olivier

the functions in the lxml namespace already print to context and return
no value so you effectively appends nil which is invalid
also, when used in a context run the default serializer is also piping
to context so if you want otherwise you need to prefix with xml://
(which is an indication that in principle there can be many variants)
here are some valid solutions (whatch the lxml.id):
\startxmlsetups xml:test
\xmlsetsetup{#1}{c}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:test}
\startxmlsetups xml:c
\ctxlua{title = test= ..
xml.filter(lxml.id(#1),xml://./attribute(title)) context(title)}
\par
\ctxlua{context(test=)
xml.filter(lxml.id(#1),./attribute(title))}
\par
\ctxlua{context(test=) lxml.att(#1,title)}
\stopxmlsetups
\starttext
\xmlprocessdata
{maths}
{?xml version='1.0' standalone='yes?c title=My title/c}

I don't know, but please provide a complete minimal example.
2) I'm trying to export to xml and have set
\setupbackend[export=yes, xhtml=yes, css=mkiv-export.css]
But
a) my Metafun/Tikz pictures aren't exported to svg :/
Currently ConTeXt does not export Metafun/Tikz pictures to svg.
b) the exported xml has namespaces problems (like error on line 63 at column
20: Namespace prefix m on math is not defined error on line 64 at column 22:
Namespace prefix m on mrow is not defined)
What am I doing wrong ? (I'm compiling with context mydoc.tex)
Could it be a validator error? The 11th line of my test document contains:
document xmlns:m=http://www.w3.org/1998/Math/MathML;
which defines the 'm' namespace.
Is there some \csname tex4ht\endcsname command or some other directive that I
should use to get my xml export right ?
ConTeXt does not use tex4ht!
Am I missing some namespace commands (there are lots of m:math and m:mrow
mathml tags int the exported xml source, this smells like a tex4ht issue)
See above.
3) I have defined some framed text with metafun overlays (like in the Context
manual)
and I'm trying to type something like
but it's not really satisfying. (hate to lose vertical space with wandering
blank spaces)
Is there a better way ?
Please provide a complete minimal example.
4) I'm trying to port the following TeX code to ConTeXt
$$\eqalign{x=1\cr y=2\cr}\qquad \hbox{haha}$$
it looks like \startformula\startalign.. doesn't allow me to do that
I somehow managed to have it by typing
\startformula
\vcenter{\starttabular[|rM|lM|]
\NC x \NC =1\NC\NR
\NC y \NC =2\NC\NR
\stoptabular}\qquad\text{haha}
\stopformula
the pdf export is fine, but the xml export is awfull (because of \vcenter I
guess)
a) Is there a way to use tables inside math mode alongside other stuff (would
be handy) ?
b) what is the correct way to type the previous text, so the pdf and xml are
fine in Context ?
Why not use \startmathalign etc. See:
