Our goals...

A powerful engine to invent (y)our future

Pharo is a vehicule Pharo is not at its end, just starting

Pharo is not our dream, it is what we have

But **every** single day we improve it

Enabler“One of the things that drew me to do the Delay refactoring, is simply that I could. That is, I was amazed that I could dig so deep so easily, see a path to improvement and effect change at a fundamental level. Excepting complexities with the Continuous Integration due to “changing the wheels on the car at 100km/h” (and one slip), it seems to have gone reasonably smoothly.  That sense of mastery is seductive.”

Enabler: Turtles all the wayA Bryant developed Seaside in Pharo ancestor (while he knew ruby, python, scheme, C, objective-C) because he could manipulate the stack behind the back of developers. Seaside is based on stack on-demand reification.

An ecosystem where innovation/business bloom

We want that **you** can make money with Pharo. We want to be able to invent solutions to existing problems.

!

We want a powerful innovative dynamic language where we can build our future.

We are a cool community

Simplicity and elegance

Simple but complete object model

Syntax fits on a postcard!

Less is more!No constructors, no static methods, no operators

No type declaration, no primitive types,

No interfaces, no need for factory

No packages/private/protected modifiers

No parametrized types

No boxing/unboxing

Still powerful

Object model

Everything is an object instance of a class !

Single inheritance !

Public virtual methods !

Protected field
