Re: [NTG-context] [NTG-Context] Problem with \usemodule[graph] and El Capitan (mac OS)

[Alan Braslau]

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.

Attached is an altered input file that works for me. No idea how much of the

is actually related to El Capitan, but:

  I added the “graph::” prefix twice)

there are save's in mp-grap ... i'll remove them


Best wishes,

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

Re: [NTG-context] [NTG-Context] Problem with \usemodule[graph] and El Capitan (mac OS)

[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
