Irb freaks out over a case stmt

bitsmith · September 15, 2006, 7:59pm

i’m writing a method within the Akill class that cascades down 2 sql
stmts inside some if and when stmts…but i get this when i added the
last branch of if stmts: what happened note : ALL ‘end’ stmts are
properly matched

class Akill
def getusd(prem,cust,serv,scat,readit)
cursor=@@conn.exec("<>>")
k=Array.new
while r=cursor.fetch() and k.size<3
k.push®
end
cursor.close
if k.size>0
k.first
else
?> cursor=@@conn.exec("<>>")
     k=Array.new
      while r=cursor.fetch() and k.size<3
        k.push(r)
      end
     cursor.close
         if k.size>0
            k.first
 else

?> #get defaults of kwd=0,kvar=700,kwh=1500
?> #else nil
?> case scat

             when scat=='KWH' 1500

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/
Languages/Ruby/QuickRef.html#23 for examples of how to write properly
formed case statements.

yes,…>>>>How do you turn off tab completion in IRB?
…how do turn off the tab because that was the case (sort of speak)
i mean i use sciteK editor the comes with the one-click installer and i
guess i puts a tab in there somewhere but i don’t know how?

How do you turn off tab completion in IRB?

bitsmith · September 16, 2006, 5:01am

in scite, just hit F5 to execute the app/script… no need to past to
irb (assuming that’s what you’re doing

I prefer my gvim and my xterm, thank you very much. How do I turn off
tab
completion in IRB?

off tab
completion in IRB?

irb -f --readline #ignore .irbrc file and load readline w/o tab
completion
irb --noreadline #disable readline altogether

It seems that I don’t have a .irbrc, but I still have tab completion.
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.

I figured it out. 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”}
