Hello

I have a problem with irb console.

When i want to write special characters like "@" and "[" or "]" i cant.
IRB simply dont let me write this characters. It is like if i was not
writing on the beyboard.

Any help?

thanks

Yes you are right. Thank you.

Now instead of executing "irb --noreadline" is there a place where i can
put the "--noreadline" option to be executed always when irb is called?

My problem is that, i am debugging an application with the "breakpoint"
instruction. This instruction opens an irb console. So I would like that
the irb console to be called automatically with the noreadline option...

Do you know how can I make it?

thanks

Try putting the following option in your .irbrc file

IRB.conf[:USE_READLINE] = nil

The pickaxe has more:

Thanks

I created the .irbrc file (because i dont have anyone) but it seems that
is not used.
I am in windows with instant rails. I created the file in the
\InstantRails\ruby directory but I think it is not the right place to
have it.

Am I wrong?
