Re: [NTG-context] \startMPcode and \startMPpage
Dear Hans,
Thank you for the reply.
Since \startMPcode … \stopMPcode form is used in the manual, I think that it
is OK to use it for all cases.
Thank you again.
Best regards,
Dalyoung

Or you could write out a shell script while processing the run.
function moduledata.archimate(filename)
local root = xml.load(filename)
warnIfVerbose( "Processing %s", filename)
local shfile = io.open(tex.jobname.. ".sh", "w")
local i = 1
for view in xml.collected(root,"diagrams/view") do
local viewName = xml.text(view,"/name")
shfile:write(string.format('mutool merge -o "%s.pdf" %s "%s.pdf" ',
viewName, i, tex.jobname))
i = i + 1
….
end
shfile:close()
and process that shell script at the end of the run.

> you can use for instance mutool etc to split pdf’s
I can’t do that simply because it would mean lots and lots of manual work
(including typing long names every time) each time I automatically produce the
PDFs. I am talking hundreds of views generated anew every time and they all
need to end up in a separate file. I need some sort of automatic flow. It’s OK
if the PDF with all the pages is an intermediate and use a tool to split this
into separate files with separate file names (so an additional step in the
workflow) but I would have to create th eextraction script automatically during
the ConTeXt run.
Alternatively, I could have a step before this to turn the input XML into many
separate XMLs and have many ConTeXt runs. Probably that is the best way to do
it. Each generated XML would have all of the original XML except it would only
have one ‘view’ in it and the rest removed.

Dear list members,
I create all my MetaFun drawings in a separate environment file where
each individual drawing sits inside a start/stopbuffer. This allows me
to easily use those drawings in all my documents using
\processMPbuffer[name]. Works just fine.
However, I also wish to have all the drawing available in a pdf file
(each drawing on a separate page). This allows me to split the pdf and
use the drawing elsewhere (e.g. in a Powerpoint) or include page(s)
from the pdf in another document.
The below MWE represent my MetaFun drawings file.
The idea is that by uncommenting the \enablemode[makepdf] I can create
the pdf file with drawings. It seems however that startMPpage does not
accept buffers (I also tried processbuffer and processMPbuffer).
Is it possible to somehow make this work?
You can use
\startTEXpage
\processMPbuffer[…]
\stopTEXpage
but loading a buffer in MPpage doesn’t work because the content of the
environment
is just passed to MetaPost and buffers can’t be loaded inside MetaPost
code unless
Hans adds a function for this, e.g.
\startMPcode
buffer("mybuffer")
\stopMPcode

This works if I change \paperwidth and \paperheight to
\printpaperwidth and \printpaperheight and change the dimensions
slightly.
Thank you, Johan

[NTG-context] \setuppapersize and \startMPpage
Dear expertise, I have the following: \definepapersize[thesis][width=169mm, height=239mm] \setuppapersize[thesis][A4] \setuplayout [location=middle, marking=on] \setuppagenumbering [alternative=doublesided, location=marginedge, state=stop] \starttext % Title page \startMPpage % Some metafun \stopMPpage % Some text \stoptext The resulting pdf has a smaller first page (thesis size) while the rest are A4 with the thesis pages place centrally. I would like to see the title page placed on an A4 sheet as well. What am I doing wrong?

because you nest a graphic, kind of

you can only include a simple usable graphic, defined with
\startuseMPgraphic; unique mp graphics are more tricky and involve
(once we have lua in tex we can find ways around this since then we can
(1) implement some of the unique housekeeping in lua and (2) fool tex
with hidden expansions)

Hi David,
without digging into depth, it works if you change MPpage into TEXpage

[NTG-context] \startMPpage ... \stopMPpage
Hans, Taco, et al,
There's a quote in metafun-s.pdf (page 539) that says You can embed
the graphic in a \startMPpage construct and process it with TEXEXEC.
In that case you have the full MetaFun functionality available.
Before processing the file, TEXEXEC will do a couple of checks on the
file. It will also make sure that the auxiliary files (mpt for
textext’s and mpo for outline fonts) are taken care of too.
I am really unsure of what this means as the code below will attest.
Simply uncomment
% \startMPpage
% \includeMPgraphic{EnglishRule}
% \stopMPpage
at the end and the file will not compile.
Just what can and cannot be used between a \startMPpage ...
\stopMPpage pair? This is first introduced in metafun-s.pdf on page
214 and wish there were more said there.

Is it because they cannot draw a straight one? This could be ture
