Many thanks for the quick fix Hans, I have tried the lmtx inclusions as well, very nice indeed (and added it to the wiki)!

[NTG-context] gnuplot-module broken under lmtx

no problem. But with the gnuplot-module I can't fix the error myself.

Re: [NTG-context] gnuplot module broken
Dear Hans,
please consider the following example in MKII:
\setupcolors[state=start]
\starttext
\startMPextensions
a := \abc;
color b;
b := \MPcolor{currentcolor};
\stopMPextensions
\startuseMPgraphic{bla}
fill fullcircle scaled a withcolor b;
\stopuseMPgraphic
\def\abc{3cm}\color[blue]{\useMPgraphic{bla}}
% Nice small black circle
\def\abc{1cm}\useMPgraphic{bla}
\stoptext
I still don't know how to reproduce this in MKIV. I tried with
MPdefinitions as you suggested, but this only works the first time
when it is used. The following example creates two equal circles
instead of two different ones:
\starttext
\startMPdefinitions
a := \abc;
color b;
b := \MPcolor{currentcolor};
\stopMPdefinitions
\startuseMPgraphic{bla}
fill fullcircle scaled a withcolor b;
\stopuseMPgraphic
\def\abc{3cm}\color[blue]{\useMPgraphic{bla}}
% I want a black 1cm circle here
\def\abc{1cm}\useMPgraphic{bla}
\stoptext
Unless MKII is more powerful than MKIV: how can I achieve the same
functionality in MKIV as I did in MKII?
Thank you,
Mojca

Hi Mojca et al.

Here's an almost minimal example:

The old ConTeXt draws a blue circle with diameter 3cm and the new
ConTeXt draws a black circle with diameter 1cm. Which one is right?
From a recent message by Hans:
- add mp functionality (immediate expansion)
It seems that ConTeXt now parses everything inside MPextensions
earlier than it did before and I don't have the slightest idea how to
account for this in the module without a major rewrite. In case that
Hans wants to keep the new functionality, I either need [quite some]
help with the module or I'll simply stick to TeX Live 2012 for the
foreseeable future ;)
For the (not texlive) module use:
\defineMPinstance[gnuplot]
[format=metafun,
extensions=yes,
initializations=yes,
method=double]
\startMPdefinitions[gnuplot] ...
and then use the gnuplot instance. This not only isolates the code, but also
gives you floats. It also means that if someone crashes the gnuplot
instance, the rest still keeps running.
Definitions are per instance and are delayed i.e. passed via the tex end
when they get expanded.
The reason for extensions being immediate (at least for now) is that it was
more easy to implement as extensions meant for mp extensions and can be for
all instances of specific (sets) of instances.
Sorry for the changes but as we have multiple instances, scale vs double and
maybe more coming it's probably worth the trouble.
Hans

Use \startMPinitializations instead of \startMPextensions, it's
global to all MP instances, though.

Hi Mojca et al.
todays beta broke the gnuplot module. This is probably due to the
changes in the MP inclusion mechanism.
\usemodule [gnuplot]
\starttext

Here's an almost minimal example:
\def\abc{1cm}
\startMPextensions
a := \abc;
color b;
b := \MPcolor{currentcolor};
\stopMPextensions
\def\abc{3cm}
\starttext
\startcolor[blue]
\startMPcode
fill fullcircle scaled a withcolor b;
\stopMPcode
\stopcolor
\stoptext
The old ConTeXt draws a blue circle with diameter 3cm and the new
ConTeXt draws a black circle with diameter 1cm. Which one is right?
From a recent message by Hans:
- add mp functionality (immediate expansion)
It seems that ConTeXt now parses everything inside MPextensions
earlier than it did before and I don't have the slightest idea how to
account for this in the module without a major rewrite. In case that
Hans wants to keep the new functionality, I either need [quite some]
help with the module or I'll simply stick to TeX Live 2012 for the
foreseeable future ;)
For the (not texlive) module use:
\defineMPinstance[gnuplot]
[format=metafun,
extensions=yes,
initializations=yes,
method=double]
\startMPdefinitions[gnuplot] ...
and then use the gnuplot instance. This not only isolates the code, but
also gives you floats. It also means that if someone crashes the gnuplot
instance, the rest still keeps running.
Definitions are per instance and are delayed i.e. passed via the tex end
when they get expanded.
The reason for extensions being immediate (at least for now) is that it
was more easy to implement as extensions meant for mp extensions and can
be for all instances of specific (sets) of instances.
Sorry for the changes but as we have multiple instances, scale vs double
and maybe more coming it's probably worth the trouble.
