Beginilah sekarang penampakan dari blog salah seorang teman, penuh dengan blank spaces.

Symbolic Mode chmod Support

2008-04-01T05:35:00.000-07:00

I put my implementation of symbolic mode support for ruby's chmod on id-ruby's googlecode svn repository. This uses Regexp#global_match in my previous post, and handles all symbolic mode chmod cases. Enjoy.

Global Match for Ruby

2008-04-01T05:22:00.000-07:00

An equivalence of Perl regular expression's /g (global match) modifier. If this doesn't make sense to you, please read perlretut manpage.


class Regexp
  def global_match(str, &proc)
    retval = nil
    loop do
      res = str.sub(self) do |m|
        proc.call($~) # pass MatchData obj
        ''
      end
      break retval if res == str
      str = res
      retval ||= true
    end
  end
end

and the cat dog house example from perlretut rewritten:


re = /(\w+)/
words = []
re.global_match("cat dog house") do |m|
  words.push(m[0])
end
p words # ["cat", "dog", "house"]
