Hi Rob, install_pp has been deprecated for a while[1], with addPrettyPrinter[2] being its replacement. Is there a reason you can't use that?
Thanks for the reminder. (I?m glad to see the documentation doesn?t actually say ?deprecated?, a word that I deprecate as a substitute for ?not recommended? :-).) I was actually testing on an oldish release of ProofPower. Later releases use addPrettyPrinter.
I was wrong about this. Later releases of ProofPower make some use of addPrettyPrinter but still use install_pp. I must have reverted to an earlier version of Poly/ML by mistake and thought things were working under Poly/ML 5.6, when they do not. Not having install_pp will be a stopper for me unless I can roll my own implementation of it using PolyML.addPrettyPrinter. Is that going to be an easy exercise?
Regards,
Rob.
