Python Algorithms

[Nick Draper]

Extend the Python interface to allow usable python algorithms.

This will need to expose details of:

• Algorithm
• Write access to workspaces (ideally only from within algorithms)
• Properties
• WrokspaceFactory

Also need to check that the code in AlgorithmFactory to register them actually works - it probably needs a bit of improvement/updating.

[Martyn Gigg]

(In [3665]) Initial setup for PythonAlgorithms. Re #952

[Martyn Gigg]

(In [3747]) Major backbone of Python algorithms. Changing and reloading while running MantidPlot is now implemented. Re #952

[Martyn Gigg]

(In [3748]) Fix a python test. Re #952

[Martyn Gigg]

(In [3749]) Add updated compiled Python init file to installer. Re #952

[Russell Taylor]

(In [3751]) Fix for tests build on Darwin. Re #952

[Martyn Gigg]

(In [3760]) Fix for asynchronous running of algorithms from Python so that they halt the script on an error. Also re-added dock updating. Re #952

[Martyn Gigg]

(In [3778]) Added validation to Python algorithms. Improved handling of Python cloned python references that were not being cleaned up. Re #952

[Martyn Gigg]

(In [3785]) Added workspace validators to Python. Greatly improved error handling for Python algorithms. Moved Mantid initialization in MantidPlot to before scripting initilzation so that useful log messages get displayed. Re #952

[Martyn Gigg]

(In [3786]) Disable algorithm reloading temporarily as it's not working quite correctly. Re #952

[Martyn Gigg]

(In [3792]) Python algorithm reloading now doesn't corrupt running a normal script twice. Fixed problems with MantidPlot crashing if Python wasn't initialized correctly. Re #952

[Martyn Gigg]

(In [3793]) Update compiled pyc file for the Windows installer. Re #952

[Martyn Gigg]

(In [3795]) Update to mantidplot python init file to ensure that the simple api is always generated. Re #952

[Martyn Gigg]

(In [3804]) Fixes for Python algorithms crash on Windows. Added logging at notice, information, warning and error level. Re #952

[Martyn Gigg]

(In [3807]) Added List validation to Python algorithms and fixed an issue with incorrect detection of boolean type parameters. Removed old example file as it is now incorrect. New example to follow with documentation. Re #952

[Martyn Gigg]

(In [3815]) Fix for Linux and Darwin builds. Forgot to include 'typename' keyword for nested types. Re #952

[Martyn Gigg]

(In [3816]) Ensure that when running algorithms from the dock, that the Python object store is refreshed so that any changes are taken into account. Re #952

[Martyn Gigg]

(In [3828]) Fix for a crash when running algorithms after running Python from an interface. Re #952

[Martyn Gigg]

(In [3850]) Minor fix to list property declaration that got picked up in testing. Re #952

[Martyn Gigg]

(In [3853]) Partial fix for Python algorithms simple api generation and workspace properties. Re #952

[Martyn Gigg]

(In [3854]) Fix for crashes when running PythonAlgorithms from Python. Re #952

[Martyn Gigg]

(In [3855]) Added Python algorithm example Re #952

[Martyn Gigg]

(In [3856]) Add a Python algorithm directory along with an example algorithm to the installer. Re #952

[Roman Tolchenov]

(In [3857]) Fixed installer build. re #952

[Martyn Gigg]

(In [3858]) Replace shipped .pyc files with ordinary .py files from their source location. Re #952

[Martyn Gigg]

(In [3859]) Remove old pyc component. Re #952

[Roman Tolchenov]

(In [3860]) Real fix this time. re #952

[Martyn Gigg]

(In [3861]) Fix problem with always on top flag not respected by scripting window. Re #952
