    The dependency metadata in a CPAN distribution is independent from the code that actually loads the needed modules at runtime, so the two can diverge, and occasionally they do. But it gets noticed quite quickly, most of the time –...

    If it were taking `@_[0,1]` as a scalar parameter, it would be printing out `2`. Incorrect. Replace sprintf with scalar and you will see that the result is exactly the same as you see here. That’s because @_[0,1] is a...

    If you absolutely cannot maintain your scripts (ie want them to live forever unmaintained) It’s not that I can. It goes back to the question you posed: “what does [maintaining such a script to keep it running] gain for the...

    Hmm. How much of a role does Plack play in that app? It parses the request parameters. That’s it. That’s the entirety of the reason that their codebase doesn’t qualify as raw PSGI. They don’t even use Plack::Response (I often...

    There are legitimate uses for eval when you are doing language-level stuff. I’m finding it hard to think of how to circumscribe them with a reasonably simple and reasonably accurate criterion though. To put it unhelpfully abstractly, eval is an...

    Dave, that won’t work exactly as written because plackup is a script, and you can only use binaries in the shebang. You would have to use #!/usr/bin/env plackup But I recommend against this. Going through plackup via the shebang line...
  • Posted Modern Perl CGI to Aristotle

    The contemporarily unique strengths of CGI as a deployment strategy are that CGI scripts ⓐ can just be dumped in the filesystem to deploy them and ⓑ do not have any of the issues of long-running processes: they tie up no resources when not in use and are extremely reliable because of the…

    In my opinion, marking private subroutines with a leading underscore is a de facto standard in the perl world. So, independently of the coverage issue, it would be a good thing to do. That would be a fair stance to...

    As others have said, your script looks like an unfinished attempt to solve a problem, and doesn’t actually do much. It just uncompresses the *dat.gz files in the current directory. For each of the files it also prints a line...

  • Posted Plack::Middleware::RedirectSSL to Aristotle

    I just shipped 1.300 of this module to the CPAN and it occurs to me that I’ve never talked about it here. I suppose I figured that what it does is so simple that there’s not much to say about it. But it‘s useful if you need what it does, and I wrote it because nobody else had.

    Maybe it's been copied into both BODY and EXTENDED tabs?

    I wonder if an input of "0" should produce an output of "0". I wonder if "--05" is a positive number.

  • laurent_r commented on Perl Weekly Challenge: Week 2

    Thank you both, E. Choroba and Aristotle, for you help. That was it: I had the same text in the body and the extended tab. I removed the text from the extended tab and it seems OK now.

  • laurent_r commented on Perl Weekly Challenge: Week 2

    Hi Mark, thank you for your comment.

    > I wonder if an input of "0" should produce an output of "0".

    Yes, I think that an input of 0 (for the number to be converted) should produce an output of 0, irrespective of the base (well, so long as the base is valid), because 0 converted to any base is still 0.

    > I wonder if "--05" is a positive number.

    That does not seem to work, because both Perl 5 and Perl 6 apparently consider that "--5" isn't a valid number.

  • Grinnz commented on Perl Weekly Challenge: Week 2

    You have to space the syntax so that it does not interpret it as the pre-decrement operator, such as "- -5" or "-(-5)". I am not sure if you'd still consider that part of the number.
