    I personally use AppConfig, the main reasons being that I've never had any trouble with it (despite using it for some quite nasty configurations), and that many of the things I write use TT2 and since AppConfig's a dependancy of TT2 it's one less thing to need to roll-out to servers.

    It can also handle configs in both UNIX and Windows styles, which is occasionally useful.

    I use Config::Simple it works very well, except for the tied hash interface where it flattens the sections into a single hash which when dumped looks like:
    'newsletter.owner_p1_font' => [], 'newsletter.contact_font' => 'Helvetica', 'newsletter.owner_city' => 'Hamilton', 'system.debug' => '1', 'armtwo.username' => [], 'newsletter.contact_y' => '150',
    The tied method of Config::IniFiles is more intuitive.

    Config::Simple is pretty widely used and if you have a problem the developer is very responsive.

    It all depends on the complexity of what you're needing a configuration file for.

    If its something relatively simple, use Config::Simple. its a VERY quick and useful format of one-to-one name->value pairs that supports comments and INI-style sections (depending on how you configure your instance of it).

    if you need something more complex, I highly recommend Config::General. this has the added advantage of using a (more or less) Apache-style configuration format, and all its cool little uses: repeatable options, nested options, inclusion of other config files, and more. this all comes at a slight performance cost as opposed to Config::Simple, of course.

    While not strictly a "configuration module", YAML (or YAML::Syck) might be of use.

    I like Config::General and I usually use it in the Gantry::Conf config framework which gives much flexibility while providing a single master conf file for everything on a server.

    I use YAML and sometimes AppConfig.

    What do you want in a configuration module?

    See Re (tilly) 6: using strict and a config file for a fairly reasonable list of wants that I had at one point, which none of those modules provides. (For the record, I'm still happy with pure Perl configuration files.)

      Well, I second tilly's requirements in this post.

      My requirements to a configuration module are:
      1. Allow nested categories.
      2. Allow list values (e.g. users=tinkywinky,dipsy,lala,po).
      3. Warn on access attempt to undefined variables.
      I am unfamiliar with have these requirements are covered, but thanks to excellent response from the monks, I have a good starting point for finding the way.
