[NTG-context] Metapost/Metafun/Tex/Context question
Hi all,
I am trying to do the following in Metapost but my new math symbol is
not recognized.
Context knows about it but Tex does not.
How can I make this work ?
Kind regards

will not go into that. This is one place where you can use the new

Matthias' reply is better for your situation, but for curiosity's sake, here is what actually happens: - MetaPost is happily reading MetaPost commands when suddenly it sees a btex command. - Now it will throw away everything upto the next etex, and it will run the external command makempx with the current filename as argument. * makempx's goal is to create a file with the same name as it's argument, but with the extension replaced with .mpx. That file will contain a series of low-level MetaPost commands for each label in the source file, and those lists of commands are separated by the MetaPost command mpxbreak. * nothing is done by makempx if the mpx file exists and is newer than the source file. ** otherwise, the source file is scanned for verbatimtex ... etex and btex ... etex blocks. These are wrapped in very simple TeX macros and written to a TeX input file. ** TeX is run, to produce a DVI file from these commands (each dvi page representing a label) ** The entire DVI file is then converted into the .mpx file in a single action. - MetaPost will now open the .mpx file as a concurrent source of commands linked to the current source file, and read commands from it up to the first mpxbreak. - The location pointer in the .mpx file is saved for subsequent labels.

[NTG-context] Metapost and TeX [OT]
I don't have any experience in metapost. I would appreciate if someone would please answer this question without me having to do thru tutorials and metapost source code. I was wondering how does metapost talk to TeX? Quicky glancing through the metafun book, I found out that you can super-impose text typeset by TeX on top of a diagram. I imagine you could do the same with mathematical equations too. So how does metapost interact with TeX? Let me guess: 1) Metapost could first write down to a file the text that it wan't TeX to typeset. It could then run TeX on the file. TeX produces a DVI file and metapost reads it back. It can then superimpose it on top of a picture. 2) Metapost could also be including within itself a simplified version of TeX. But that would be reinventing the wheel. So how does it happen in reality? The reason that I am asking is that I am interested in producing some diagrams using the libHARU PDF library (a C++ library to produce PDF files). Beautiful Text support, however, is missing from the library. I was wondering if I could hack it up so that I could somehow use TeX for the text part and C++ calls for the graphics part. ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context
Re: [NTG-context] Metapost and TeX
This is not exactly an answer to your question, but it might solve your problem. You can use overlays with any figure, see cont-eni.pdf page 150ff. The mechanism is not so much the tex-engine TeX but one of the many little add-ons that come with ConText and exploit features of PDF. In particular, you can use your PDFs directly in ConText. I found this easier than to teach my picture producing applications to use the right fonts in the right way at the right place.
