The most basic approach for Intellisense is to extract the information from the ASTs, which I imagine is all that C# or VB have to do. The next is to take the ASTs and transform them by removing the "dangerous" parts. Then, you could actually run the simplified ASTs and introspect on the resulting object. This can be made increasingly "complete" by removing less and less stuff -- at greater and greater risk of creating a program that won't run to completion or will have undesirable side effects. To put this another way, I may need to run "initialize" in order for my object to express the proper methods -- but the code in "initialize" could well overwrite the OS for all I know. Any class that depends on method_missing (in Ruby) or __getattr__ (in Python) for method implementation is going to be problematic for Intellisense. And Rails' ActiveRecord is one of the most pathological cases I can imagine. -- Curt Hagenlocher [EMAIL PROTECTED] _______________________________________________ Ironruby-core mailing list [email protected] http://rubyforge.org/mailman/listinfo/ironruby-core
