Objective

Python has a great potential in Slicer3. Its uses span:

Python command line modules (advantages: easy to write, access to Python libraries, don't need a compiler to write new modules)
matplotlib and scipy Python modules (they provide a matlab-like processing environment for images directly within Slicer).
Python as Slicer's scripting language (for automating task and programmatically access modules - this is Dan's new baby!)

Approach, Plan

In the project week, we plan to

solve building issues, check stability on different platforms
threading issues: modifying the MRML scene from Python command line modules in a thread-safe way
calling modules from Python
provide a Python equivalent to ScriptedModules
define what aspects will end up in the next release
propose a working set of Python command line modules (interact with Sonia's breakout session on Tuesday?) to be included in the next release
write documentation on how to write Python command line modules

These are the results of the MIT project week (largely Dan's work)

Implemented Python Modules
- Add search for Python in ModuleFactory
  - Can put .py files in the CommandLine Module path
- Execute Python within Slicer
  - Full access to VTK, vtkTEEM, vtkITK, etc.
- If the Python module provides an XML description, and an Execute function, will be added as a CommandLine Module
ToDo
- Check-in (needs USE_PYTHON guards)
- Progress reporting
- Simplify the API
- Automate command line parsing using XML description

Later on, after the meeting

command line parsing has been completed (in a very simple way, without needing access to XML)
API has been simplified
