Hello
I'm trying to port a big 300+ pages math course full of macros from
plain XeTEX to ConTeXt mark IV (ubuntu 12.04+ stand alone beta)
and I'm having some difficulties, could you please help ?
My questions :
1) does lxml.att("#1","some tag") really work ?
the next snipet doesn't work for me:
\startluacode
function set(node)
p = lxml.att(node,"p") -- or p = lxml.att(lxml.id(node),"p")
end
\stopluacode
\startxmlsetups xml:section
\ctxlua{set("#1")}
\stopxmlsetups
it looks like it returns the p attribute of the node before #1
the following snipet works though (which is strange because I looked in
the context source and it gives
\def\xmlatt#1#2{\ctxlua{lxml.att("#1","#2")}}...)
\startxmlsetups xml:section
\ctxlua{p = \xmlatt{"#1","p"}}
\stopxmlsetups
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 :/
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")
Is there some \csname tex4ht\endcsname command or some other directive
that I should use to get my xml export right ?
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)
3) I have defined some framed text with metafun overlays (like in the
Context manual)
and I'm trying to type something like
\inmargin{some label}
\startMyFramedText...\stopMyFramedText
Yet, the text in the margin is after the framed text :(
(fiddling with the "location" setting (low, ..) doesn't allow me to have
the in margin text right next the top of the framed text
I somehow found a dirty workaround with typing a blank space
\defineframedtext[Property][frame=off,background=OverlayProperty,before={}]
and
\inmargin{some label}\noindent\startMyFramedText...\stopMyFramedText
but it's not really satisfying. (hate to lose vertical space with
wandering blank spaces)
Is there a better way ?
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 ?
Best regards
Olivier... really enjoying utf, xml, lua inside TeX as well as other
nice ConTeXt features

The separation between mkii and mkiv wasn't visible enough, I think. It would now make sense to add a category "manipulating xml in lua code" (or something to that effect) under the mkiv heading and then add the lxml code. All best Thomas -- Prof. Dr. Thomas A.

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 ?

If needed, you can hide this behind macros: \def\startmyStatement {\framed[struct=no, offset=2cm]\bgroup\myStatement\bgroup} \def\stopmyStatement {\egroup\egroup} Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 13+ messages in thread

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 > {\framed[struct=no, offset=2cm]\bgroup\myStatement\bgroup} > > \def\stopmyStatement > {\egroup\egroup} > > Aditya > ___________________________________________________________________________________ > > If your question is of interest to others as well, please add an entry > to the Wiki! > > maillist : ntg-context@ntg.nl / > http://www.ntg.nl/mailman/listinfo/ntg-context > webpage : http://www.pragma-ade.nl / http://tex.aanhet.net > archive : http://foundry.supelec.fr/projects/contextrev/ > wiki : http://contextgarden.net > ___________________________________________________________________________________ > > ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 13+ messages in thread
