Up until version 4.2, command-line IPython had a readline frontend, which was
replaced by prompt_toolkit in IPython 5.
rlipython brings that classic
readline functionality to IPython 5.4+ and 6.0+.
See ipython/ipython#10364 for information.
Try it out
You can try out
rlipython like this:
Do I have to do that every time?
No. To have
rlipython enabled automatically, do this:
import rlipython; rlipython.install()
This will enable
rlipython for the default IPython profile if you run it
python or the active profile if you run it from
rlipyton.install(), you can go back to starting IPython just by
ipython without the extra configuration flag.
import rlipython; rlipython.uninstall()
Python 2 or Python 3
rlipython will work in both Python 2 and Python 3. However, as of May 15th,
2017, IPython 6.0 is the only released version of IPython which supports a
interactive_shell_class, but IPython 6.0 only works in Python 3.
So if you want to use
rlipython in Python 2, you will have to install the
IPython 5.x branch from git, or
wait for IPython 5.4 release.
