Thanks Matt, but I use the command line only. I'm a VI user in
general, so the learning curve to get emacs running would be a bit
extreme.
Mike, the link you posted didn't have any code posted, but it linked
to something called 'tecla' that appeared to have something like what
I wanted. However, I tried it and it doesn't work as advertised. It
also dies on a keyboard interrupt, making it pretty useless.
Where can I find out more about callable IDL? It sounds pretty
interesting, but a quick through the help only told me what it was,
not how to use it. Do you think it's feasible to use, e.g., the bash
command line as a frontend for IDL using callable idl? That seems
like the ideal situation, though I'm not sure it makes sense in terms
of keeping variables accessible to a session.
And yes, my intent is to have an IPython equivalent for IDL, though
even the default python terminal includes readline support.
Adam
