Hello, Thank for your interest in RoelTyper. The user interface of RoelTyper is the class TypeCollector. To know the types of an instance variable of a class use the method "typeInstvar: var ofClass: aClass". For example: *TypeCollector typeInstvar: #x ofClass: Point* This returns an ExtractedType object that contains the collected information for #x about its assignments, interface (messages sent on it) and links with other variables. To calculate types from this information, send the message "types" on an ExtractedType object. For example: *(TypeCollector typeInstvar: #x ofClass: Point) types* returns an ordered collection with the class "Number". You can also ask types of the temporary variables of methods. For example: *TypeCollector typeTmpsIn: (Point >> #>) ofClass: Point* returns an indentitydictionary with the extracted types for ^ (the type of the return value) and aPoint (the parameter of the method).

Hi,

I'm trying to figure out how to use the RoelTyper in Pharo. When I go to the page: http://decomp.ulb.ac.be/roelwuyts/smalltalk/roeltyper/ it talks about the refactoring browser, but it's a Cincom browser. I see that you're the most recent editor of RoelTyper on SqueakSource, so I assume you have some idea how to use it.

Any assistance would be appreciated!

Thanks ../Dave
