( [id://3333] : superdoc . print w/replies, xml ) Need Help??
I have been watching the recent development of this module with much interest - it fills a hole nicely on win32 that has sorely been missing (not to mention perfectly answers my recent question). I downloaded and compiled v0.03 today (after installing VS.net... whew!), but ran out of time to play with it. Now i see v0.04 is on CPAN... i'll have a look tomorrow.

I have a couple of suggestions:

  • a tie() interface
    I can't imagine it'd be much more work, but an (additional) interface that would allow you to tie() an arbitrarily complex variable to shared memory would allow cross-platform developers to simply
    tie( $variable, $^O eq 'MSWin32' ? 'Win32::MMF' : 'IPC::Shareable', { ... } );
    Ideally it would accept the same options as IPC::Shareable, even if they're just aliases. I know this is very similar to what the module currently does, but having the tie keyword in your code makes it easier to understand what's happening. And i think this would be an even more 'programmer-friendly' interface (nothing wrong with the current one), as it hides virtually _all_ complexity. Tie a hash, fork, update it in one process, the other process can see the changes. Or tie separately in two different processes. Also makes for easier 'inter-process signalling' (via do{} while ! $share, or Tk's waitVariable()).

  • binary and/or ppm package
    Given this is win32 we're talking about, it might be a good idea to host a binary and/or a ppm package somewhere for those that don't have access to multi-billion-dollar windows compilers and/or the knowledge required. :) Just a thought.

    • Are you posting in the right place? Check out Where do I post X? to know for sure.
    • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
      <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
    • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
    • Want more info? How to link or How to display code and escape characters are good places to start.
