  • Posted Switch lots of things on at once to The Incredible Journey

    Many people already have codes like

    and so on at the top of each script they write. For scripts which I don't intend to publish anywhere, I have a module (which I accidentally called Z not knowing there was already a module of the same name on CPAN),…

    If you're using XS and C in your Perl module, you might have to worry about memory errors. There are tools like valgrind or memory sanitizer which you can use of course:

    There are some very long modules on CPAN, like this one I saw yesterday: https://metacpan.org/release/Lingua-EN-Opinion/source/lib/Lingua/EN/Opinion It has a dictionary of English words, and each word has its own hash reference, with ten different keys. It might be better not to...

    Which of those wouldn't be followed by a semicolon? I think package NAMESPACE and package NAMESPACE VERSION are both always followed by one. BLOCK just means {something} doesn't it, so the matching is package\s+.*?\s*(;|\{)....

    I think it will help for the next version. It seems to me that PAUSE could check for a semicolon, but there are probably exceptions for that. This line: https://metacpan.org/release/Go-Tokenize/source/lib/Go/Tokenize.pm#L43 also produced an unusual error message, refer to the comment...

    Following on from the Gzip::Libdeflate I mentioned before, I also made this: Gzip::Zopfli

    Both Zopfli and libdeflate seem to excel at compressing JSON fil…

  • Commented on Inline::F2003
    It's OK to upload unfinished modules to CPAN. File::Find is not only on CPAN but in the Perl core and yet it is insufficiently mature to have sensible functionality or documentation. Just think "My module cannot possibly be worse than...
  • Posted New compression module Gzip::Libdeflate to The Incredible Journey

    I've turned the libdeflate compression library into a CPAN module:

    Gzip::Libdeflate

    This is the gzip compression method, but updated.

    It's supposed to be much faster and better than libz (the original gzip library).…

  • Ron Grunwald commented on Inline::F2003

    Hi Ben,

    I really appreciate you trying out Inline::F2003. And... thank you for reporting the bug. Clearly I need to add the latest Perl release into my test procedure from here on.

    As for CPAN, yes, I can see that would be more convenient. There are several reasons I've decided against a CPAN package; one being that I feel the module is not yet sufficiently mature.

    Thanks again for your time!

    Ron.

  • Aristotle commented on I failed to pause before blogging
    It seems to me that PAUSE could check for a semicolon, but there are probably exceptions for that.

    Indeed there are.

    $ perldoc -f package | head -4
    package NAMESPACE
    package NAMESPACE VERSION
    package NAMESPACE BLOCK
    package NAMESPACE VERSION BLOCK
  • Grinnz commented on I failed to pause before blogging

    There is no reason the BLOCK has to be on the same line either.

    Anyway, making sure you don't have anything following 'package' on the line is an appropriate solution in this case. And probably including a comment so the problem doesn't accidentally reoccur.

  • Toby Inkster commented on I failed to pause before blogging

    I think the indexer probably goes through line by line to avoid slurping in the whole file.

  • Grinnz commented on Switch lots of things on at once

    Also check out Import::Base, which is just a wrapper around Import::Into to make this specific sort of module.
