This is pyrepl, a readline-a-like in pure Python.
It requires python 3.8 (or newer) and features:
- sane multi-line editing
- history, with incremental search
- completion, including displaying of available options
- a fairly large subset of the readline emacs-mode keybindings (adding more is mostly just a matter of typing)
- a liberal, Python-style, license
- a new python top-level
- no global variables, so you can run two or more independent readers without having their histories interfering.
- no hogging of control -- it should be easy to integrate pyrepl into YOUR application's event loop.
- generally speaking, a much more interactive experience than readline (it's a bit like a cross between readline and emacs's mini-buffer)
There are probably still a few little bugs & misfeatures, but I like it, and use it as my python top-level most of the time.
To get a feel for it, just execute:
python pythoni(One point that may 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)
If you like what you see, you can install it with the familiar
$ pip install git+https://github.com/bretello/pyrepl
which will also install pythoni script.
PyPi version coming soon
