ghost suggestions using session history

[mlucool]

In general, much of the code in my session depends on other code in that session. This makes ghost suggestions awkward to use at times. As somewhat simple example, in one session I do:

Then in the next I type ra<tab> and IPython suggests I use x again:

Any suggestions on how to improve this? Is it possible for users that find this distracting to disable it?

In general, it is not possible to tell whether arbitrary Python code has all of its dependencies satisfied.

You can use %config TerminalInteractiveShell.autosuggestions_provider = None to disable the suggestions. Documentation on configuration will tell you how to make this permanent, should you wish to do so.

See #13451.

As the configuration option suggest, we want in the long term to provide other autosuggestions, we could make those based on the completer, or other methods. Right now it's true that it purely match on history exactly. If you have any suggestion on a type of provider we welcome all ideas.
