crash with straight tab

[rdp]

Hello.
Get this:

When I hit "tab" within irb with nothing entered yet (i.e. first keystroke is tab).
Cheers!

Have you tried latest version of rb-readline?

Download 0.4.0 from GitHub and follow the installation instructions from here:

http://blog.mmediasys.com/2009/09/21/pure-ruby-readline-released-0-2-0/

Also, please check or provide the contents of ~/.inputrc

[rdp]

that was with trunk as of today.

C:\dev>cat %HOMEPATH%/.inputrc
cat: \Users\packrd/.inputrc: No such file or directory

C:\dev>cat %HOMEPATH%/.irbrc
require 'irb/ext/save-history'
#History configuration
IRB.conf[:SAVE_HISTORY] = 100
IRB.conf[:HISTORY_FILE] = "#{File.expand_path('~')}/.irb-save-history"

Hello,

I can confirm it happens with double tab, not with a single tab.

PS: For the record, your version of Ruby seems odd and 10 patchlevel lower than latest RubyInstaller... Will look into this issue later.

I think I encountered this and may have addressed it in my fork (of just a little while ago). I saw I think the same traceback.

After making a number of other small changes I'll issue a pull request from the fork I have at http://github.com/rocky/rb-readline

I believe this is fixed now in git. Please verify and close.

[luislavena]

Indeed.

As of current master, this issue is solved.
