Provide a -run option for interactive use

[Eero Aaltonen]

This is a feature proposal for using ipython -pylab

I'm doing scientific analysis and I would like to start pylab with my dataset definitions and scripts loaded to the interactive namespace. I've put my dataset definitions in definitions.py

Running
ipython -pylab definitions.py

will execute everything, but my definitions do not show up with %who

Running
ipython -pylab -c "%run defs.py"

will execute the interpreter.

I propose that either
ipython -pylab definitions.py
is altered such that the definitions are listed in %who

or that you add a -run option, so that the effect can be achieved by executing
ipython -pylab -run definitions.py

[Eero Aaltonen (ejn)]

Running
ipython -pylab -c "%run defs.py"

will *exit* the interpreter.

damn typo

Second.

It seems the functionality of the "-c" option changed somewhere between 0.8.1 and 0.8.4. In 0.8.1 you can do

ipython -c "print 5"

and the interpreter stays alive after printing 5. In 0.8.4 the interpreter quits.

I strongly suggest adding a -run option to mimic the old -c. Until then, I will stay with 0.8.1...

Now the -i option lets you ask for the interpreter to stay interactive:

amirbar[junk]> ipython -i -c 'x=10;print x**3'

So all you need to do is add -i to your calls, and we have a -c that matches the default Python behavior.

The above is the current trunk behavior.
