Pyjama: Getting Started

You can start Pyjama up by running the ./pyjama (Linux and Mac OSX) and pyjama.bat (Windows).

Pyjama GUI

Error creating thumbnail: /bin/bash: /usr/bin/convert: No such file or directory

Error code: 127

Pyjama is divided into two windows:

  1. Editor
  2. Shell and Output


The Editor allows you to edit files. From the editor, you can select a section of code and press F5 to run part of your script interactively. If you don't have anything high-lighted, pressing F5 will run the entire file.

In the interactive command box, you can enter as much code as you like, ENTER will evaluate the code in the box (you may have to press ENTER twice, if you have a multi-line expression).
