in reply to Module Proposal: Tie::SortHash

Well, I don't know why you are proposing it here and not the modules list, but since you are ... :)
Personally, I would rather see that funtionality added to an existing module like Tie:IxHash, or Tie::LLHash which both already do some internal sorting. Maybe working with one of those authors (Sarathy and Ken Williams, respectively) to see if your methods will fit into their modules before adding another tied hash sorting module.

Cheers,

    I had origionaly thought of doing that, however, they both have different symantics, and are fairly particular:

    Tie::IxHash attempts to give you more of an array like behavior and keeps the order that things were added to the hash, just like arrays. I'm not trying to do that.

    Tie::LLHash gives you the ability to poke and prod the hash, while keeping it's state of where and how things were entered into it. I'm also not looking to do that.

    The advantage is that there is no overhead or fluf with Tie::SortHash. It's designed to do one thing, rather transparently. I like the transparent part, you don't get that with the other two modules.

    Transparent meaning, for most cases, there's only two 'out of the ordinary' lines in your program. One usees Tie::SortHash, the other implements the tie.

      If your internals can't work with theirs (I would doubt that they can't work together), then it would be ok as it's own module. It just seems that this would fit nicely, at least into IxHash. It keeps the order of the entered keys, but also has some ordering/sorting methods (Reorder, SortByKey and SortByValue). With add something like SortByInput (off the top of my head) it seems you would only need to reorder the array IxHash keeps in parallel to the hash.
      Just my $.02, but I do like the idea. I would only want to make sure it wouldn't be more valuable in conjunction with another module, rather than stand alone. I suggest asking for any comments on the modules list.

    Where is the modules list? I have a couple modules that are worth posting, but I couldn't find a good place to do it. The code catacombs seem ... not very well suited to posting modules.

      Go to here (or the 04pause.html page in your favorite mirror) and read how to become a CPAN contributor. A link to the modules list, and what to send to it, are on that page.

        Oh.... I thought you meant there was a perl monks page for modules. I'm J/JE/JETTERO there, so I knew that one. ;)
