What is Pyjamas?

Pyjamas

is a Rich Internet Application (RIA)

Development Platform for both Web and Desktop.

It contains a Python-to-Javascript compiler, an AJAX framework

and a Widget Set API. Pyjamas started life as a Python port of

Google Web Toolkit,

the Java-to-Javascript compiler. Read the

FAQ

and the

list of features.

What is Pyjamas Desktop?

Pyjamas Desktop

is the Desktop version of

Pyjamas

Pyjamas Desktop allows the exact same python web application source code to be

executed as a standalone desktop application (running under Python) instead of

being stuck in a Web browser.

For Free Software platforms, most Linux Distributions now come with

Pyjamas and Pyjamas Desktop pre-packaged: Debian/Testing, FC13,

ArchLinux and Gentoo.

For Windows, Pyjamas Desktop uses

MSHTML.

Since MSHTML comes pre-installed on Windows (as part of IE), there is very

little extra to download (other than Python itself).

Why should I use Pyjamas?

You can write web applications in python - a readable programming

language - instead of in HTML and Javascript, both of which become

quickly unreadable for even medium-sized applications. Your

applications design can benefit from encapsulating high level

concepts into classes and modules (instead of trying to fit as much

HTML as you can stand into one page); you can reuse - and import -

classes and modules.

Also, the AJAX library takes care of all the browser

interoperability issues on your behalf, leaving you free to focus

on application development instead of learning all the "usual"

browser incompatibilities.

I dont get it

Fear not - you are not alone: the true purpose and nature of Pyjamas

is blissfully opaque to many. Will and Abe come to the rescue, with

their Guide to Pyjamas.

On mature reflection, however, its probably best to read the

FAQ

and then contact the people on the

mailing list.

Who are the developers?

The original code for the UI Widget Set and the DOM support libraries came

from GWT, and was ported by

James Tauber. James wrote the original pyjs compiler. Luke Leighton took over the

project in 2008, and updated the UI Widget Set, improved the compiler and

created the three Pyjamas Desktop runtimes. He has been maintaining and

driving the project ever since. Bernd Dorn and his colleagues from

Lovely Systems

did some dramatic compiler improvements for 0.5. Kees Bos joined because he was not interested in learning JavaScript,

but learn he definitely did. Kees is responsible for the majority of the

vast improvements and the more esoteric python interoperability in the

compiler, such as "yield", long data type and much much more. In total, there are around fifty contributors to the Pyjamas Project:

a complete list can be found in the copyright file in the Pyjamas

distribution.

The code for the Pyjamas Web Site, which is itself a Pyjamas application,

was written by Luke Leighton.

It has some pretty cool features, none of which "stand out", which is as

it should be. Technology is not there to "dazzle" people or get in the way

by promoting itself and its own "glory": its there to make peoples lives

simpler and easier.
