And the code is as follows

\startMPcode
path A ; A :=(0cm, -1cm)--(1cm, -1cm);
path B ; B :=(13.5cm, -1cm)--(14.5cm, -1cm);
path C ; C :=(12cm, -1cm)--(11cm, -1cm);
path D ; D : =(4cm, -1cm)--(3cm, -1cm);


  ^ remove the space


drawarrow A; drawarrow B; drawarrow C ; drawarrow D ;
\stopMPcode

Unless I uncomment D it gives the above error.

Re: [NTG-context] Error in MetaFun LMTX

2020-02-25 Thread Jan-Erik Hägglöf
Sorry, I discovered the issue myself

Space between the : and = sign was the origin of error.

Problem solved by itself

[NTG-context] Error in MetaFun LMTX

2020-02-25 Thread Jan-Erik Hägglöf
The following code gives an error, my goal is to draw 4 different arrows but 
only three functions successfully.

The error log shows

metapost> initializing number mode 'scaled'
metapost log> 
metapost log> loading metafun, including plain.mp version 1.004 for metafun 
iv and xl
metapost log> 
metapost log> >> unknown path D
metapost log> ! Isolated expression.
metapost log>  
metapost log>:
metapost log> <*> ... :=(12cm, -1cm)--(11cm, -1cm); path D ; D :
metapost log>=(4cm, 
-1cm)--(3cm, -1cm)...
metapost log>

And the code is as follows

\startMPcode 
path A ; A :=(0cm, -1cm)--(1cm, -1cm);
path B ; B :=(13.5cm, -1cm)--(14.5cm, -1cm);
path C ; C :=(12cm, -1cm)--(11cm, -1cm);
path D ; D : =(4cm, -1cm)--(3cm, -1cm);
drawarrow A; drawarrow B; drawarrow C ; drawarrow D ;
\stopMPcode

Unless I uncomment D it gives the above error.
