Hi pharoers, If I do the following in a minimal Pharo image, using the command line: ./Pharo --headless Pharo.image eval "Object subclass: #TestClass instanceVariableNames: 'one' classVariableNames: '' package: 'IS-Test'." I get the class created. However, if I try to pass the following argument to eval: "Object subclass: #TestClass instanceVariableNames: 'one' classVariableNames: '' package: 'IS-Test'. TestClass compile:'one ^one' classified: 'accessor'." I get an UndefinedObject>>DoIt (TestClass is Undeclared). At first I thought it could be that it takes sometime to compile the class, so added some delay: "Object subclass: #TestClass instanceVariableNames: 'one' classVariableNames: '' package: 'IS-Test'. (Delay forSeconds: 5) wait. TestClass compile:'one ^one' classified: 'accessor'." But again: UndefinedObject>>DoIt (TestClass is Undeclared). I even tried to do: "Object subclass: #TestClass instanceVariableNames: 'one' classVariableNames: '' package: 'IS-Test'. Smalltalk saveAndQuit." and after that add only a method by passing: "TestClass compile:'one ^one' classified: 'accessor'. Smalltalk saveAndQuit." But again: UndefinedObject>>DoIt (TestClass is Undeclared) How do I add a method to a class using the command line? Thanks in advance Nacho ----- Nacho Smalltalker apprentice.
