Dear all, I have updated my OS to El Capitan, and all my scripts including MPgraph functions such as gdata do not work anymore (script without such functions are working without any trouble). Would someone know how to get rid of this issue? I thank you very much.

a short code sample:

x:=u*1cm;

a1:=6;

a2:=5;

hauteury:=a1*y;

echelleMEP:=1/10*hauteury/a2;

gdata("explexpl.d",s,

y1:= scantokens(s1);

y2:= scantokens(s2);

draw (7.5*x, y1*echelleMEP)--(8.5*x, y2*echelleMEP) withcolor 0.6 white;

);

incomplete ... how is this called ... what is explexl.d

Dear Taco, I thank you very much for your time. It works perfectly and I will emulate these modifications in my other figures. I have no ideas about the problem, I just figured out that it came from El Capitan because I updated the OS yesterday, however I also had to reinstall MacTex, so it may also come from a different version of ConText? Dear Hans, I would like to thank you for all your work on Metafun, as it is the tool I use now exclusively for all my scientific figures. Best regards, Louis-Solal 2016-09-01 11:43 GMT+02:00 Taco Hoekwater :

Hi,

I am on El Capitan as well (10.11.6).

ConTeXt ver: 2016.08.29 22:53 MKIV beta

Attached is an altered input file that works for me. No idea how much of the problem is actually related to El Capitan, but:

* \usemodule[graph] defines a special MP instance called ‘graph’. You need to use that because otherwise the metapost graph macros will not load (that is why I added the “graph::” prefix twice)

* Something is wrong with the file closing, so I added an extra definition for 'graph_close_file' (no idea why it does not work out of the box. Sorry to you and Hans).

Best wishes, Taco

No, this is a feature, not a bug! According to the original graph macros, the data files are kept open, and thus subsequent reads will pick up successive data sets in a single file. This is explicitly stated in the documentation. A consequence for us in ConTeXt mkiv, where the metapost code is called in multiple passes, is that one must explicitly close the data file if one does not want this feature. This, too, I documented. So don't break John Hobby's code by removing the saved. Alan
