2. Pharo?
A progressive, open-source Smalltalk platform
for professional use.
A fork of Squeak
Stable
Bugs fixed fast
But still open to innovations

3. In a nutshell
Pharo = language + IDE + update mechanism
Pure object-oriented programming language
(Smalltalk)
Dynamically typed and trait-based
Open and flexible environment
Platform for Seaside and Aida/Web web
frameworks
Used Monticello (Metacello planned for 1.1)

4. Pharo statement
«Pharo's goal is to deliver a clean, innovative, open-
source Smalltalk environment. By providing a stable
and small core system, excellent developer tools, and
maintained releases, Pharo is an attractive platform to
build and deploy mission critical Smalltalk
applications. Pharo is MIT licensed and is steered by a
board of benevolent dictators. The board makes final
decisions if no consensus can be reached within the
community. Pharo fosters a healthy ecosystem of both
private and commercial contributors who advance and
maintain the core system and its external packages.»
