Question

Hello, all. What's the best way to run a TWiki AddOnPackage script (specifically the 'bin/publish' script from the PublishAddOn) from a Plugin (specifically in the afterSaveHandler)? I'm making a plugin that publishes the topic's static HTML page after each save, so the static version of my TWiki is updated in real-time instead of using a cron-job with delays.

Thanks.

Answer

Simply execute the command with backticks. Pseudo example:

    my $err = "";
    my $output = `/path/to/program -c 'any parameters' $web.$topic |
/path/to/second_program in pipe if needed 2>&1`;
    if ($?) {
        $err = "Could not execute program";
    } else {
        # do something with $output;
    }

Pay attention to the current directory. Do not assume that it is set to the current twiki/bin.
