For our May presentation, Stephane Ducasse will present the vision behind
Pharo and how that is been implemented incrementally across multiple
releases. In Stef's words:
"The vision of Pharo is based on three pillars:
- First we want to make sure that Pharo is used to develop complex and
robust systems (by complex we means multiple millions lines of code or
- Second we want Pharo to be a modular system that can be versatile (Pharo
on iot, on large servers, in the web browser….)
- Third Pharo should be an evolvable system that can adapt to new needs
(modular tools, first class slot, new debuggers, packages…).
Sometimes it can be unclear that we follow this vision but over the years
we are delivering this vision and we will continue. In this talk I will
briefly recall the vision behind Pharo and show the achievements so far. I
will show that our development is heavily backed by tests.
In the second part of the talk I will focus on the current effort to
improve the user interface. I will show that the reimplementation of the
Spec UI framework is a cornerstone of the future replacement of Morphic and
use of GTK.
I will also answer questions about Pharo 11 and Pharo 12."
Stephane is an Inria Research Director, currently lead the RMoD team (
http://rmod.lille.inria.fr/ ). Stef is an expert in language design,
software quality, program understanding, program visualisations,
reengineering and metamodeling. Among his contributions we can list: traits
(implemented in Pharo, Perl, PHP and other languages); Moose, an
open-source software analysis platform ( http://www.moosetechnology.org/ ).
Stef is one of the leaders of Pharo ( http://www.pharo.org/ ), a dynamic
reflective object-oriented language supporting live programming, and of the
industrial Pharo consortium ( https://consortium.pharo.org/ ).
Stef works regularly with companies such as Thales, Wordline, Siemens,
Berger-Levrault, Arolla, and others on their software evolution problems.
Stef has authored a couple hundred articles (
