This page describes the planning of Pyjama Editor and Shell. The Pyjama IDE is a cross-platform environment for learning about computing. This is part of the Pyjama Project.


Getting Source Code

For those with write permissions to the SVN Bryn Mawr College source code repository:

svn co Pyjama

You can browse the source code here:

You will also need:

  • mono
  • gtk (and libgtk2.0-cil-dev, for package-config files)


To build everything, run "make" in the root:

cd Pyjama

That will build platform independent modules/Myro.dll, modules/Graphics.dll, and languages/Scheme.dll.

To run code:

cd Pyjama


There are 5 directories in the Pyjama folder:

  1. bin - contains the startup exe and dll files
    1. bin/Lib - contains the standard Python libraries
  2. languages - contains the language definition files for Python, Ruby, Scheme, and Dinah
  3. modules - Cross-language modules that can be used by all Pyjama languages
  4. examples - sample code, broken down by language
  5. src - the code to run the Pyjama Project

Pyjama is written in IronPython, using the Gtk# graphical toolkit. The Python files for the Pyjama Project are in Pyjama/src/*.py. They are:

  • - base classes for Document interface
  • - the Editor Window
  • - base classes for the Engine interface
  • - setup and startup code
  • - code to read DLL data
  • - the Shell Window
  • - utility functions and classes
  • - base class for Shell and Editor

Pyjama is an editor and executor of code from a Language. Languages are defined in Pyjama/languages and define two items: editor document, and an executor engine. Pyjama has 4 languages, in various states of completeness:

  1. Python (finished)
  2. Ruby (nearly finished)
  3. Scheme (somewhat working)
  4. Dinah (drag and drop language, just started)
  5. Sympl (experimental Lisp-like language written in Python for the DLR)

A Language file in Pyjama/languages/*.py defines the editing document, and the shell executor API. Documents can do things like open, save, and display data for editing. Engines can do things like execute, execute_file, and parse files. Engines also allow for the languages to share data and functionality.
