Question

How do I invoke a Squeak method when given the method name as a string? is it possible ?

Answer 1

Try:

perform: aSymbol
perform: aSymbol with: anObject
perform: aSymbol withArguments: anArrayOfArguments

Where aSymbol is your method selector. For example instead of 1 + 2 your could write:

1 perform: #+ with: 2

If your method selector is stored as a String, you have to convert it to a Symbol first:

1 perform: '+' asSymbol with: 2

5 perform: 'raisedTo:modulo:' asSymbol withArguments: #(2 3)
