Hi, What options do we have in terms of type annotations in Pharo?
I stumbled upon TypePlug this https://marcusdenker.de/talks/08ParisTypes/08ParisTypePlug.pdf (or rather this http://scg.unibe.ch/archive/masters/Hald07a.pdf ) which enabled type annotation for Squeak such as ~~~~~~~~~~~~~~~~ Fruit>>mixWith: aFruit <:type: Fruit :> ^ (Array with: self with: aFruit) <:type: Array E: Fruit :> ~~~~~~~~~~~~~~~~ Orange>>color ^ (Color orange) <:type: Color :> ~~~~~~~~~~~~~~~~ (or even blocks) [ :a1 <:type: Integer :> :a2 <:type: Integer :> | a1 + a2 ] ~~~~~~~~~~~~~~~~ obviously something like this wouldn't even compile in Pharo (does Sqeak have different syntax for pragmas, or did the TypePlug change the syntax?) And my question is... is there a port of this, or something similar? I've also found this http://randycoulman.com/blog/2013/02/12/specifying-types-for-smalltalk-fit/ Which is a framework for integrated testing that uses pragmas such as ~~~~~~~~~~~~~~~~ makeBatchWithdrawalOn: aDate note: aString <fitTakes: #(#{Date} #{String})> <fitReturns: #{Fixture}> ^(BatchWithdrawalFixture date: aDate note: aString) systemUnderTest: systemUnderTest ~~~~~~~~~~~~~~~~ Right now I am exploring what options we have in Pharo in terms of type annotations (before writing yet-another-library ;-)). Thanks, Peter
