  • How can a module that's unable to say what it actually does ever have a bug?

    YAML::Tiny is a misnomer and should be abandoned unless it is intending to become compliant to the YAML spec.

    Did you ever answer http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2007-06/msg00783.html [mpe.mpg.de]
    ?
    • YAML looks simple, but is actually a bloated nightmare. Implementing the full YAML spec is tedious and difficult. Most uses of "YAML" actually use only a small subset. YAML::Tiny tries to implement this small, simple subset. I'm not sure why you find this so hard to understand.
      • > YAML::Tiny tries to implement this small, simple subset.

        If you read the manpage from the first to the last line you still have no idea what this small, simple subset actually is. Whenever you have a small, simple YAML file that fails, or a small simple perl data structure that cannot be represented in YAML via YAML::Tiny, you cannot tell if it fails because of a bug or if it fails because the author has chosen to not implement some aspect of that small simple YAML file or that small, simple perl datast
        • I see your point, but I'm more willing to have the line between "bug" and "outside the spec" be negotiated between author and user. Many specs are so hairy that in practice you can only deal with them by having a general idea of their intent, then trying stuff to see what breaks. I haven't read the HTML 4 spec (746 KB of text), don't plan to, and couldn't remember it all if I did, but I can still hack together a webpage based on my rough understanding.

          The same goes (for me) for YAML::Tiny -- I'll use it for the simple stuff where it works, and deal with any breakage when I see it. YAML's in a unique position here, because it tries harder than most markup to look simple, but it is also formally specified. Kind of like English -- I usually get it right when speaking it but, even as a native, I don't pretend to remember all the rules.
