Fixing Ruby irb window console in Netbeans for Windows

Posted on by

PS: This worked for Netbeans 6.7 RC2, however it will HORRIBLY break any attempt to use irb from the windows command line

If you right click on a project in Netbeans then go to ‘Ruby Shell (IRB)’, you should get dropped into a ruby IRB window.

Unfortunately for most of you on windows, you might get this instead …

Netbeans irb window fails on windows

An easy fix is to go to irb.bat and comment out the first 7 lines of code so that it looks like this

#@echo off
#@if not "%~d0" == "~d0" goto WinNT
#\bin\ruby -x "/bin/irb.bat" %1 %2 %3 %4 %5 %6 %7 %8 %9
#@goto endofruby
#:WinNT
#"%~dp0ruby" -x "%~f0" %*
#@goto endofruby
#!/bin/ruby

require "irb"
 
if __FILE__ == $0
  IRB.start(__FILE__)
else
  # check -e option
  if /^-e$/ =~ $0
    IRB.start(__FILE__)
  else
    IRB.setup(__FILE__)
  end
end
__END__
