Questions tagged [pharo]

Pharo is an open-source Smalltalk environment. It is a derivative of Squeak and is MIT licensed with some original Apple parts remaining under the Apache 2.0 license.

Pharo is a fork of Squeak, an implementation of the object-oriented, dynamically typed, reflective programming language Smalltalk.

Appearing in 2008, Pharo focuses on removing unessential code from Squeak and serves as the reference implementation of Seaside, a web application framework for developing web applications in Smalltalk. The name Pharo may be a reference to the famous Pharos lighthouse in ancient Alexandria.

Pharo 4.0 includes much improved tools to analyse and view objects and to construct browsers (Spotter, Playground, Glamour framework).

Squeak before version 4.0 shipped under the Squeak license, which was not an approved OSI open source licence, Pharo has a policy that enforces contributors to agree to publishing their code under the MIT License. Many packages that are integrated into the Squeak base distribution are optional in Pharo. Unlike Squeak, Pharo ships with TrueType fonts bundled already.
