[graalvm-users] GraalVM-Users Digest, Vol 5, Issue 1

Wed Aug 1 19:11:51 PDT 2018

So, I added awt() and the print command.  The plots shows up and then when
the scrip ends it disappears.  Is there a way of running polyglot inside
pry, so that the script does not end and plotting works?  Or do I need to
write a loop to prevent the script from ending?  Pry would certainly be
best.

Thanks
