Re: [NTG-context] Fwd: Macro to write a vector (Metafun) is broken

22 Mar 2018

      Hi Hans,
No, I did not check this file but only update context Standalone. I guess
this is not enough since the compilation does not work.
Thank you

Subject: [NTG-context] Macro to write a vector (Metafun) is broken
To: mailing list for ConTeXt users 
Hello Hans,
The macro you wrote to draw the arrows of the vectors does not seem to
work anymore.
Thank you
Fabrice
Did you check ou tthe latest meta-imp file? Alan and I added more and also
changed the interface a little which might have consequences.
