Pharo is too much fun!

by Sean P. DeNigris

The problem with Pharo is sometimes it's too much fun to play with objects. I could've just renamed my 5 classes via copy/paste, but I couldn't resist... classes := Smalltalk organization classesInCategory: packageName. classes do: [ :cls | | newName | newName := newPrefix, (cls name allButFirst: oldPrefix size). (RBRenameClassRefactoring rename: cls to: newName) execute ] ----- Cheers, Sean -- View this message in context: http://forum.world.st/Pharo-is-too-much-fun-tp4820809.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Pharo-VM-mac-stable.zip one day earlier than #1 you are taking wrong folders :) check at /get-files/50 /get-files/40 that points to the âblessedâ ones. alsoâ¦ âstableâ does not has sense anymore, they are there for backward compatibility. Now we use âstable-YYYYMMDDâ format meaning we declared it stable that dayâ¦ and then we point consolidated versions (/get-files/etc.) to the appropriate one.
