(y or n) I can’t even tell what you are trying to do / write. It looks like “freak out” in your world means “respond with everything when I hit tab in a place without context” which is exactly what it should do. If not, I suggest turning off tab completion first and trying again. But beyond that, I still can’t tell what you are trying to write. If it is something like: case scat when scat == ‘KWH’ 1500 scat==‘KVAR’ 700 scat==‘KWD’ 0 end then yup. You’re going to get a syntax error as you did in your email and that has nothing to do with IRB. Try it just using ruby -c -e ‘…code…’ for example to see. GIGO. See [http://www.zenspider.com/](http://www.zenspider.com/) Languages/Ruby/QuickRef.html#23 for examples of how to write properly formed case statements. ---

How do you turn off tab completion in IRB? ---

I’d like to have readline support but no completion, but I don’t know what to put in my .irbrc (or .inputrc) to disable this. –Ken ---

Somehow, at the end of /usr/lib/ruby/1.8/irb/completion.rb, I have the lines: if Readline.respond\_to?(“basic\_word\_break\_characters=”) Readline.basic\_word\_break\_characters= " \t\n"\'`\>\<=;|&{(" end Readline.completion\_append\_character = nil Readline.completion\_proc = IRB::InputCompletor::CompletionProc So I just put code in my .irbrc to undo it: #disable completion, so that hitting tab just inserts a tab character Readline.completion\_append\_character = “” Readline.completion\_proc = lambda {|x| x+“\t”} –Ken B.
