'Disable irb autocomplete

The latest version of irb introduced an autocomplete that is quite buggy and I don't generally like to be distracted by an autocomplete, any idea how I can disable it?

Solution 1:[1]

Try putting this in your ~/.irbrc

IRB.conf[:USE_AUTOCOMPLETE] = false

Solution 2:[2]

We can pass the --noautocomplete command line option when invoking IRB.

irb --noautocomplete

Alternatively we can set a configuration option in ~/.irbrc or one of the other locations specified in the documentation

IRB.conf[:USE_AUTOCOMPLETE] = false

Starting a Rails console will respect this configuration but for a one-off we can provide the command line option. Be sure to pass any Rails options before the --

rails console --sandbox -- --noautocomplete
