logie17 has asked for the wisdom of the Perl Monks concerning the following question:

I'm just getting my feet wet with YAML, and a quick search on cpan reveals a number of modules to load/dump yaml files into perl structures. Any suggestions as to what is good, not so good, and bad? I found YAML::Tiny, which appears to do exactly what I need, any thoughts?

Thanks,

    If your needs are simple, e.g. config files, then YAML::Tiny may be sufficient. Here's how they compare:

    • YAML -- the "official" standard, implemented in pure Perl, but very "heavy" due to the flexibility it offers

    • YAML::Syck -- XS implementation using the libsyck library; fastest

    • YAML::Tiny -- a pretty full subset of YAML in less than 100 lines of pure Perl

    -xdg

    Unless you have a specific need, YAML::Syck (written by Audrey) and YAML (written by Ingy) are considered the gold standards. The first is an overylay on the Syck library (written in C) and the second is a PurePerl module.
    My criteria for good software:
    1. Does it work?
    2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

    I use YAML::Syck and have never had any problems with it. The heavy lifting stuff is written in C for speed.

    They have compatible APIs so use the best one available for your purposes. In your case I'm guessing that's Tiny, Syck, or pure, in that order? 

    use Best [[qw(YAML::Tiny YAML::Syck YAML)], [qw(Dump Load)]];

    But make sure to test YAML::Tiny with your data, and shift it off the list if it breaks.
