Talk on “Newspeak” today
11 March, 2008
Jens Lincke informed the mailing list that the are hosting a talk today (11th March) by Gilad Bracha on Newspeak, described as a new dynamic language, descended from Smalltalk and Self.
From Jens’ note:
Newspeak is a new dynamic language, descended from Smalltalk
and Self. Like Self, Newspeak is a message based language: all
computation – even an object’s own access to its internal structure – is
performed by sending messages to objects. However, like Smalltalk,
Newspeak is class-based. Classes can be nested arbitrarily, as in Beta.
Since all names denote message sends, all classes are virtual; in
particular, superclasses are virtual, so all classes act as mixins.
There is no static state in Newspeak. Instead, top level classes act as
module definitions, which are independent, immutable, self-contained
parametric namespaces. They can be instantiated into modules which may
be stateful and mutually recursive. Naturally, like its predecessors,
Newspeak is reflective: a mirror library allows structured access to the
program meta-level. In this talk, we’ll expand on these topics,
illustrating interesting uses such as class hierarchy inheritance and
domain specific language support.
Gilad Bracha is a Distinguished Engineer at Cadence Design Systems.
Previously, he was a Computational Theologist and Distinguished Engineer
at Sun Microsystems. He is co-author of the Java Language Specification,
and a researcher in the area of object-oriented programming languages.
Prior to joining Sun, he worked on Strongtalk, the Animorphic Smalltalk
System. He received his B.Sc in Mathematics and Computer Science from
Ben Gurion University in Israel and a Ph.D. in Computer Science from the
University of Utah.
The talk is from 16:00-17:00, at the Hasso Plattner Institut, B-E.2 (library). Directions can be found at: http://www.hpi.uni-potsdam.de/hpi/campus/anfahrt.html
