[IPython-dev] Logging commands using the %logstart magic

[Phil Elson]

Thanks Wes,

I explicitly am not asking about the notebook, which I know does this
admirably (and is what I would use too).
I've been asked for command line behaviour from the (I)Python terminal
which records input and output in an almost exact fashion to that of
"%logstart", except logstart does not store stdout, only IPython displayed
output.

I haven't yet dug into the possibility of redirecting stdout to IPython
out, or indeed directly out to file with the associated input, but I
imagine there will be some buffering issues that I'd like not to have to
deal with, if the functionality already exists in IPython.

Cheers,
