How to prevent IRB from asking to Display all possibilities?

I've enabled tab-completion in IRB by adding the require "irb/completion" to my ~/.irbrc file.

Now, IRB keeps asking me to type y before displaying the properties:

irb(main):001:0> 42.
Display all 112 possibilities? (y or n)

Is there some setting I can add to my .irbrc file to make the default behavior be to simply display all the possibilities?

Solution

  • Since IRB uses GNU Readline, it can be also affected by contents of ~/.inputrc file. You can get the behaviour that you described by setting these options in ~/.inputrc :

    set completion-query-items 0
set page-completions off

    as described in this answer on Super User.

    However, this also affects Bash and possibly other programs using Readline, which may be either completely undesired annoyance, or a pleasant surprise :)
