progressbar
Python progress bar project with support for HTML5 in the IPython Notebook.
Two progress bar implementations are provided, one using ASCII and one using HTML/CSS/Javascript. Perhaps at some point these can be amalagamated into a single object that displays HTML in notebook and ASCII in a terminal/qt console.
The Rich one is implemented by inserting an HTML5 progress element into the notebook and manipulated with Javascript.
A class that wraps an iterable/iterator, ProgIter is provided for use in monitoring for loop progress.
I included some css adapted from this excellent post to make the html bar look nice, this should be appened to your ~/.ipython/profile-[profile]/static/custom/custom.css (replacing [profile] with your profile name, usually default unless you have a custom profile)
