Re: [NTG-context] Conflict between MetaPost (LMTX) and cmarrows

Hi,

you can't assume fuzzy scratch variables as used in

  def flex(text t) =   % t is a list of pairs
hide(n_:=0; for z=t: z_[incr n_]:=z; endfor
dz_:=z_[n_]-z_1)
z_1 for k=2 upto n_-1: ...z_[k]{dz_} endfor ...z_[n_] enddef;
  newinternal n_; pair z_[],dz_;

to be official .. in mpxl we use names like

  temp_pair_z

i.e. a temp_ namespace (as well as a mfun_ one) for all these 
potentially clashing short names


you could do

  newinternal n_; pair z_[],dz_;

at the top of your file (because we don't use them) but stil ...

you can make a minimal failure example but I gues sthat the solution
has
to be in the mf macros (as there is where some pair/numeric clash
happens)


indeed, as i mentioned, some variable is not set up right

you need to patch (probably in all these arrow files)

save x,y,x_,y_;

to

save x,y,x_,y_,z_;

and (in mapto)

   numeric x,x_[],y,y_[];

to

   numeric x,x_[],y,y_[];
   pair z_[];

I don't know, but from the message it looks like some 'local' variables
is not saved and defined. I'm surprised that loading some mf file works
at all (because it also assumes some mf related definitions). I also
hav
eno clue if such a package adopts 'core' metafun code (and mpiv metafun
is different from mpii).


It's a generic, "pure" MetaPost package:

https://www.ctan.org/pkg/cmarrows 


that doesn't make it immune from clashes in used variables with differnt 
types ... metafun is more than plain mp so more can clash


Fonts are in /fonts/source/public in a TeX Live distribution, in case it 
helps.
i have a rather minimal tex setup so i can't run that (i'm not going to 
clutter my system now)
