Pharo is a minimalist reflective dynamically typed object-oriented language. Pharo is inspired from Smalltalk: Its full syntax fits on a postcard. Its model is simple: everything is an object instance of a class, methods are all public virtual, attributes are first class objects and are protected. There is single inheritance and traits. And nothing else! (see http://mooc.pharo.org). Still Pharo is a real language that is started to be used in industry http://pharo.org/success and http://consortium.pharo.org. The entire Pharo stack is MIT. Pharo reflective core is bootstrapped from source code. Experiences shows that we can have down to 11k (adding 2 smallint) and that a simple web app can be trim down to 500 kb.
In this talk I will present Pharo in a nutshell: Syntax, model, but also user stories. I will show the vision of the project and where we want to go. I will present some key architectural choices. I will show some powerful features such as stack on the fly reification and their application: contextual breakpoint, on the fly program transformation.
Bio: I'm one of the core developer of Pharo, head of the consortium and helping consortium engineers.
