pyrepl

For ages now, I've been working on and off on a replacement for readline for use from Python. readline is undoubtedly great, but a couple of things irritate me about it. One is the inability to do sane multi-line editing. Have you ever typed something like:

>>> for i in range(10):
...     for i in range(10):
...         print i*j

into a Python top-level? Grr, that "i" on the second line should have been a "j". Wouldn't it be nice if you could just press "up" on your keyboard and fix it? This was one of the aims I kept in mind when writing pyrepl (or pyrl as I used to call it, but that name's taken).

IMHO, the best way to get a feel for how it works is to type

$ python pythoni

and just play around. If you're used to readline's emacs-mode, you should feel right at home. One point that might confuse: because the arrow keys are used to move up and down in the command currently being edited, you need to use ^P and ^N to move through the history.

PyRepl development happens on its pages at codespeak.net.
