Description

I have binding.irb in a ruby file of my Rails 7.2 app.

I run a RSpec test, enter the binding session, hit n (alias of next as per my .irbrc file) and get the following error:

001> n

Maybe IRB bug!

The same doesn't happen if I enter next instead 🤔

Ps: the w alias works fine

IRB.conf[:COMMAND_ALIASES][:w] = :whereami
IRB.conf[:COMMAND_ALIASES][:n] = :next

This is because :next, :catch and :break are treated specially. Original names of these commands are :irb_break, :irb_catch and :irb_break. This will be fixed in #1004. However, I think it's better to have a warning when aliased command name does not exist.

Current workaround is to set IRB.conf[:COMMAND_ALIASES][:n] = :irb_next.

I'm seeing a very similar error when trying to do IRB.conf[:COMMAND_ALIASES][:r!] = :reload!. This alias used to work as is. Not sure when it changed / started failing, and I don't know how to try with older versions since irb is now installed as a default gem (I'm on irb v1.14.3). I can open a separate issue for this if needed, but the error is the same.

Command reload! was removed from rails in this pull request https://github.com/rails/rails/pull/53741

tompng avatar Jan 03 '25 17:01 tompng

@tompng Ok... so instead of IRB.conf[:COMMAND_ALIASES][:r!] = :reload! I can just add this to my .irbrc and it works:

def r! = reload!

Not sure how this gets registered, but I found it here:

IRB::HelperMethod.all_helper_methods_info.last
=> {display_name: :reload!, description: "Reloads the Rails application."}

Ironically, the method version of r! (in my .irbrc) is what I used to use, but it was failing in IRB so I found out how to do the command alias approach which did work. Now the opposite is true. Guess I'm not keeping up well!

Thanks for the link and nudge to try something different.
