Subject: [ruby-dev:37515] [Bug #910] optparse with regexp

Bug #910: optparse with regexp
http://redmine.ruby-lang.org/issues/show/910

起票者: rubikitch .
ステータス: Open, 優先度: Normal

optparseでオプション引数にマッチすべき正規表現を指定した場合の挙動が変わっています。

#!/usr/local/bin/ruby
require 'optparse'
opts = {}
ARGV.options do |o|
  o.on("-T [level]", /^[0-4]$/) {|x| opts[:T] = x }
  o.parse!
end
puts "opts=#{opts.inspect}"


$ ruby187p72 -v optparse-regexp.rb -T1
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux]
opts={:T=>"1"}
$ ruby19 -v optparse-regexp.rb -T1
ruby 1.9.1 (2008-12-20 revision 20892) [i686-linux]
opts={:T=>["1"]}
