[IPython-dev] running cells in notebook programmatically

[Robert Alexander]

Hi. Running a script from the command line (using IPython 2.3.0) containing:

from IPython.nbformat import current as nbf
from IPython import get_ipython

nb = nbf.new_notebook()
firstCell = "print hello"
cells = [ nbf.new_code_cell(firstCell) ]
nb['worksheets'].append(nbf.new_worksheet(cells=cells))

ip = get_ipython()
print "ip"
print ip
for cell in nb.worksheets[0].cells:
    if cell.cell_type != 'code':
        continue
    print "cell.input"
    print cell.input
    ip.run_cell(cell.input)

returns the error:

ip
None
cell.input
print hello
Traceback (most recent call last):
  File "//.ipython/createnotebook.py", line 17, in <module>
    ip.run_cell(cell.input)
AttributeError: 'NoneType' object has no attribute 'run_cell'

Is there a correct way to do this?
