New features

This is a list of work-in-progress features, or features that haven't been released in a 2.0.x version.

Core

vistrails prefix

'vistrails.' prefix added to package names. Allows to use VisTrails as a library.

Bundles

Fixed and updated the bundle installation system. It allows to automatically install required Python packages when they are first imported without restarting VisTrails or entering commands.

Supports the 'pip' installer (on both UNIX and Windows), apt (through Python binding) and Fedora (with yum -- binding currently broken, only uses cmd)

Automatic conversion

Connecting incompatible ports is possible if a Converter subclass exists for these specific types.

Documented in the users' guide.

Enumeration for module ports

It is possible to declare the possible values on a module's input port; the UI then shows a combobox.

Parallel execution

Changes to the interpreter allowing the parallel execution of modules in a pipeline.

This is opt-in for modules and thus doesn't break modules that use thread-unsafe code. Supports threads, multiprocessing and IPython clusters.

Replaces parallelflow.

Packages

parallelflow

Provides a way to execute modules or groups on an IPython cluster, via a Map module. Also has IPython UI to set it up, and an API to use IPython in other modules.

Documented in the users' guide. First implemented in Oct, 2012 by Fernando.

Note that it becomes obsolete with multithreaded-interpreter although a lot of code was reused.

matplotlib

Replaces pylab with a better interface (specialized modules autogenerated from matplotlib's docstrings).

Lots of examples in examples/matplotlib/

tabledata

A package allowing to load CSV files and NumPy arrays, to display them as a table and to convert between datatypes.
