Progress bar does not work in ipython notebook due to '\r' issued _after_ output string about python-progressbar HOT 4 CLOSED

Some experimentation and googling suggests that the problem is not the timing 
of '\r' issuance, but that '\r' in ipython notebook doesn't do what it does in 
the terminal, since "IPython Notebook is not a terminal emulator". Therefore, 
in a terminal IPython instance:
In [1]: print 'hello\rgoodbye'
goodbye

whereas in IPython Notebook, you get:
In [2]: print 'hello\rgoodbye'

hello
goodbye

Issue 27 on this tracker suggests the use of a javascript implementation.

Hi Peter, 
in IPython 0.13.1 (+Chrome), I get identical behavior in the notebook and the 
shell:

In Notebook
In [1]: print 'Hello\rGoodbye'
Goodbye

In IPython shell:
In [1]: print 'Hello\rGoodbye'
Goodbye

Anyhow - thanks for pointing me to the fancy javascript implementation.

I'm merging this into issue 27.

Minor comment, but in the suggested work-around (which works for me) the line 
is actually 283, not 238. This is verified to work for progressbar 2.3 using 
Python 2.7.3 and IPython 0.13.1 on Windows
