# This program is a wrapper for asciidoc which watches the source text file for
# any changes, which automatically triggers a regeneration of the asciidoc
# output.
#
# Usage: 
#   Put this file on your PATH, chmod a+x it, and then run it just as you would
#   run asciidoc, e.g.
#
#       autoasciidoc test.txt 
#
#   You can pass any asciidoc options through the program.

  if new_mtime > last_mtime
    puts "Regenerating asciidoc output."
    `asciidoc #{ARGV.join(' ')} #{file}`
    last_mtime = File.stat(file).mtime
  end
  sleep 1 # check in one second intervals
  new_mtime = File.stat(file).mtime
