Live Typing automatically annotates variable types based on the objects assigned to them, and method return types based on the returned objects. IDEs can exploit this information to greatly improve the development tools and the programming experience, bringing some of the benefits of Static Typing tools to Dynamically Typed Languages. Live Typing benefits are boosted in Live Development Environments because the same VM is used to run the system under development and the IDE. Type information can be obtained from the running code no matter if that code is part of the language’s core, the development tools, or the system under development. The more code is run the more type info it will provide. For Live Typing to be usable, the VM has to collect the information as fast as possible, in objects that have to be accessed and configured from the development environment. This paper presents how the OpenSmalltalk-VM was modified to accomplish this task and the challenges we have for future versions.
