Running tidy in scripts

If you want to run Tidy from a Perl, bash, or other scripting language you may find it of value to inspect the result returned by Tidy when it exits:

• 0 = if everything is fine
• 1 = if there were warnings and
• 2 = if there were errors.

Example Perl script

if (close(TIDY) == 0) {
  my $exitcode = $? >> 8;
  if ($exitcode == 1) {
    printf STDERR "tidy issued warning messages\n";
  } elsif ($exitcode == 2) {
    printf STDERR "tidy issued error messages\n";
  } else {
    die "tidy exited with code: $exitcode\n";
  }
} else {
  printf STDERR "tidy detected no errors\n";
}
