# = open3.rb: Popen, but with stderr, too
#
# Author:: Yukihiro Matsumoto
# Documentation:: Konrad Meyer
#
# Open3 gives you access to stdin, stdout, and stderr when running other
# programs.
#

#
# Open3 grants you access to stdin, stdout, and stderr when running another
# program. Example:
#
#   require "open3"
#   include Open3
#   
#   stdin, stdout, stderr = popen3('nroff -man')
#
# Open3.popen3 can also take a block which will receive stdin, stdout and
# stderr as parameters.  This ensures stdin, stdout and stderr are closed
# once the block exits. Example:
#
#   require "open3"
#
#   Open3.popen3('nroff -man') { |stdin, stdout, stderr| ... }
#

module Open3
  # 
  # Open stdin, stdout, and stderr streams and start external executable.
  # Non-block form:
  #   
  #   require 'open3'
  #
  #   stdin, stdout, stderr = Open3.popen3(cmd)
  #
  # Block form:
  #
  #   require 'open3'
  #
  #   Open3.popen3(cmd) { |stdin, stdout, stderr| ... }
  #
  # The parameter +cmd+ is passed directly to Kernel#exec.
  #
  # _popen3_ is like _system_ in that you can pass extra parameters, and the
  # strings won't be mangled by shell expansion.
  #
  #   stdin, stdout, stderr = Open3.popen3('identify', '/weird path/with spaces/and "strange" characters.jpg')
  #   result = stdout.read
  #
  def popen3(*cmd)
    pw = IO::pipe   # pipe[0] for read, pipe[1] for write
    pr = IO::pipe
    pe = IO::pipe

pid = fork{
      # child
      fork{
	# grandchild
	pw[1].close
	STDIN.reopen(pw[0])
	pw[0].close

pr[0].close
	STDOUT.reopen(pr[1])
	pr[1].close

pe[0].close
	STDERR.reopen(pe[1])
	pe[1].close

exec(*cmd)
      }
      exit!(0)
    }

pw[0].close
    pr[1].close
    pe[1].close
    Process.waitpid(pid)
    pi = [pw[1], pr[0], pe[0]]
    pw[1].sync = true
    if defined? yield
      begin
	return yield(*pi)
      ensure
	pi.each{|p| p.close unless p.closed?}
      end
    end
    pi
  end
  module_function :popen3
end

if $0 == __FILE__
  a = Open3.popen3("nroff -man")
  Thread.start do
    while line = gets
      a[0].print line
    end
    a[0].close
  end
  while line = a[1].gets
    print ":", line
  end
