8. Our goals...

9. A powerful engine
to invent (y)our future

10. 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

11. 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.”

12. Enabler: Turtles all the way
A 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.

13. An ecosystem where
innovation/business bloom

14. 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.

15. We are a cool community

• Using Inspectors
• Talk and interact with objects
• Programs are objects too

47. Simplicity and elegance
Simple but complete object model
Syntax fits on a postcard!

48. 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

49. Object model
Everything is an object instance of a class
!
Single inheritance
!
Public virtual methods
!
Protected field

50. The complete syntax
exampleWithNumber: x
“A method that illustrates every part of Smalltalk method syntax”
<menu>
| y |
true & false not & (nil isNil) ifFalse: [self halt].
y := self size + super size.
#($a #a ‘a’ 1 16rFF 2r1010101010101010101 1.0)
do: [ :each | Transcript
show: (each class name);
show: (each printString);
show: ‘ ‘].
^ x < y
