Hi,

This might not be the right place to ask this question, but want to give it a try anyway!

I've installed the ConTeXt minimals (Mark IV!) recently, and running the command:

context --version

yields the following output:

... MTXrun | current version: 2010.07.30 11:35

Now I want to generate a few plots using the graph-module (by John D. Hobby) of MetaPost, which I used in the past to make high-quality plots. But when I add the following statement:

input graph ;

to the preamble of my MetaPost file and run the command:

mpost plot.mp

The run aborts with the following messages:

...

...

texnum.mp texnum.mpx

! Unable to make mpx file. l.17 init_numbers(btex $-$etex, btex$1$etex, btex${\times}10$etex, Transcript written on texnum.log. TeXExec | processing graphic 'texnum.mpx' TeXExec | runtime: 1.547143

...

...

texnum.mp texnum.mpx

! Unable to make mpx file. l.17 init_numbers(btex $-$etex, btex$1$etex, btex${\times}10$etex, Transcript written on plot.log.

So where to go from here? Do I need to install additional TeX related stuff to get it working? Anybody any suggestions, please? Thanks in advance!

Regards, Gerard Verhaag

P.S.

By the way, if I use MetaPost within ConTeXt using:

\loadmarkfile{m-graph}

\starttext \startMPcode . /[MetaPost code] . / \stopMPcode \stoptext

than everything works just fine!

Hi Gerard,

that's because of a change in ConTeXts metapost, you can use

\startMPpage <Your MP Code here> \stopMPpage

MetaPost from ConTeXt is not able without big changes to run standalone, so you might need to load the MetaPost version from TeXlive, the way how to do so depends on your OS...

Greetings

Hi Martin, Okay, thanks for your answer! Embedding the code in my ConTeXt file works well, but I was used to obtain my MetaPost figures seperately using the mpost-command! Regards, Gerard Verhaag

The module is loaded with \usemodule[graph].

Hi, So I understand that both statements: \loadmarkfile{m-graph} \usemodule[graph] are actually the same thing! Regards, Gerard

So I understand that both statements:

\loadmarkfile{m-graph}

\usemodule[graph]

are actually the same thing!

Both work but they are not the same thing.

\loadmarkfile loads only the given file with the extension “mkii” MkII and “mkiv” for MkIV and only used in modules.

\usemodule does a lot more than this, the first is that it checks for the given module with different prefixes (the graph module has a “m-” prefix which means it’s a core module) and it also looks for file with different extension, this means it doesn’t matter if the module is called m-graph.tex, m-graph.mkiv or even t-graph.mkiv, \usemodule will always load the module while \loadmarkfile will only load m-graph.mkiv

When you load a file with \loadmarkfile and the file is not present you will get a message on the terminal to give a different file name which aborts the tex run while \usemodule will only give a message on the terminal but the processing isn’t stopped, as a last thing \usemodule loads a module only once while \loadmarkfile will always read the file.

Wolfgang

Thanks for explaining the differences of the two statements! Regards, Gerard
