  • Commented on The removal of the lexical topic feature in 5.24
    P5P outsider here. I read through the whole thread "Salvaging lexical $_ from deprecation" and I think that the intent from RGS was correct: let's just talk more about this issue before ditching something that might be useful indeed. RGS...
  • Commented on On The Mojolicious Codebase
    @Joel: thanks for the thorough answer and the pointers. Re ‘discouraging’: if you wanted to communicate your feelings, you were successful. I’m still not sure it was the right tactic to let the feelings slip :) The article is interesting...
  • Commented on cpanparty is over
    Hi! I'm a bit slow, but I still think that the idea might be great and maybe most people (me included) just don't realize it. I read the article you pointed to, but really didn't make much out of it....
  • Commented on cpanparty is over
    Hi! Before you shut it down, just a feedback. Even at a second look, I did not understand what the purpose of cpanparty is and what problem it aims/aids to solve. You might want to add something about *why* anyone...
  • Posted Data::Tubes to polettix

    I released a new distribution - Data::Tubes.

  • Commented on On The Mojolicious Codebase
    I did a light research (well, just a query in DuckDuckGo actually) and didn’t find anything, so I’ll just shoot in the dark. Hopefully in a civil and respectful way, even if I said “shoot”. I was somehow tickled by...
  • Commented on Pure-Perl XML
    @Joel thanks!...
  • Commented on Pure-Perl XML
    @Joel: I agree too, Mojolicious is not the kind of "installing half of CPAN" thing that sometimes makes me look for alternatives. WRT my community experience, there are always two ends in a communication and they can be both wrong,...
  • Commented on Pure-Perl XML
    @Joel not sure what you mean with your comment. My goal is the equivalent operation of a fat-packing; in such cases, having a module that has less dependencies (especially when they are guaranteed) is easier to include than one with...
  • Commented on Pure-Perl XML
    @Joel thanks for the hint. Mojo::Dom seems fine for projects where I use Mojolicious, but for standalone-ness I'd probably look into DOM::Tiny which is derived from it. I'd be interested in any discussion about "practicality" vs "correctness" as the comment...
  • Posted Pure-Perl XML to polettix

    In the past I sometimes used XML::Tiny and I found it perfect for the job. Agreed, I had to struggle only with very little and under-control XML, so I knew I could do without a full-fledged XML Parser.

  • Posted teepee to polettix

    I know this is probably the worst time of the year to blog about something different than Perl 6... but I had this article under construction since about one month, and some Christmas vacations helped to give it the final touches! I hope someone will…

  • Commented on Logging wide characters with Log4perl
    You might want to update the link to the "Test::Builder's Unicode issue" article - it's currently broken. Thanks for the good advices!...
  • Posted Changes, nags and git hooks to polettix

    I use Dist::Zilla with a few plugins, including NextRelease and Git::Check. I was always nagged by the fact that committing actually left the

  • Commented on A general profile photo that looks in the camera
    That's a good advice... also considering that I see my image is already cached in the PerlWeekly repository/website, so my photo change on Gravatar is of little help probably......
  • Posted A general profile photo that looks in the camera to polettix

    After looking at today's issue of Perl Weekly, I remembered of a nice advice by MJD that basically boils down to: make faces look…

  • Posted Wrapper...l to polettix

    I published a new article about Perl in my blog. It's about wrapperl, a wrapper for Perl customized invocation. Find the article here and happy reading!

  • Posted Deployable to polettix

    I just wrote about a program I crafted some time ago... in Perl. Happy reading if you're interested into producing smarter tarballs! The article is here.

  • Commented on blog change... again...
    @fluca1978 I'm actually not doing the switch because of any issue with blogs.perl.org - I love the site and I think that the people behind it are amazing. I only wanted something supporting a less "online" workflow and the additional...
  • Commented on Parse::RecDescent and number of elements read on the fly
    @Jeffrey too bad that posts in group discussions get deleted eventually. Did you copy your full considerations somewhere else?...
  • Posted blog change... again... to polettix

    It seems that I'll never really be happy with blogging.

  • Posted system(), run()... roll_your_own() to polettix

    I'm working on a program that is thin wrapper around the execution of many other programs (mainly shells scripts) in Linux. The initial - and working! - choice was to use system():

    my $code = system {$program} $program;
    

    but it showed some limit…

  • Commented on Graphics::Potrace
    @Ben: actually it's already at https://github.com/polettix/Graphics-Potrace - thanks for asking!...
  • Posted Graphics::Potrace to polettix

    A few months ago I released Graphics::Potrace, that provides Perl bindings to the potrace library. So, if you want to convert rasters into vectors from Perl... you know where to go.

  • Commented on origami envelopes
    @Toby: thanks for the hint, even tough I don't know exactly where I can use it to enhance the program. BTW, 140/99 is a nice approximation but the aspect ratio for A4 paper is exactly the square root of 2....
  • Posted origami envelopes to polettix

    I've always been fond of origami, and in some periods I also had time to fold some as a hobby. Alas, this is not the case any more... most of the times.

    I'm also proud to produce my greeting cards for birthdays and occasions, when I remember to actually make one (which happens seldom... bu…

  • Commented on Why my()?
    I thought that in school they teached how to behave as well. Trying to bend this blogging platform to show only "approved" (by who?) Perl content does not seem to show particular skills in this sense, lest the bad habit...
  • Commented on Haven't Blogged in a While...
    Seems interesting! Is it feasible/easy to set up a system with subcommands a-la git? I would suggest to write the examples with fully expanded keywords (field instead of fld, method instead of mth, ...), it might save you a few...
  • Commented on Parse::RecDescent and number of elements read on the fly
    In this particular case, the possibility to produce a self-contained Pure-Perl module was important in order to have a single script with all the needed stuff inside. Anyway, in my complete and total ignorance of Marpa I would be curious...
  • Posted Parse::RecDescent and number of elements read on the fly to polettix

    I recently had to develop a small parser for some coworkers and I turned to Parse::RecDescent for handling it. The grammar was not particularly difficult to address, but it had some fields that behave like arrays whose number of elements…

  • Matt S Trout (mst) commented on The removal of the lexical topic feature in 5.24

    The _ prototype doesn't really help with things like @$ so far as I can see, unless you're saying that I need to rewrite everything that's currently 'foo { ... } ...' to 'foo sub (_) { ... } ...' which, um, really?

    Plus there's plenty of existing code that doesn't call the thing that usess $_ until several layers down, and needing to thread _ prototypes through all of that (and how do you do that when method calls are involved when they don't even honour prototypes?) strikes me as un-perlishly-un-DWIM, and if anything rather reminds me of IO monad lifting in haskell.

    I think …

  • Reini Urban commented on The removal of the lexical topic feature in 5.24

    Flavio Poletti: You are right. The CoC sidebar was only written to explain the background why this removal suddenly went through. Without 2nd deprecation. With those new CoC rules technical criticism on wrong decisions is not possible anymore, they are effectively shut down, which led to much surprise damage done.

    But even without, nobody arguing on p5p has any technical insight of the actual problems and the future problems this removal does cost. On RT there is still some knowledge left, but this forum is also censored.

    Now with the new pumping it will even get worse, as he…

  • Reini Urban commented on The removal of the lexical topic feature in 5.24

    RGS: You are right, that the adoption rate of my $_ and the _ prototype was a problem. I would explain that with the experimental burden. Nobody is using any experimental p5p feature at all (besides say), esp. since all the successful features are not coming from p5p, they are coming from CPAN. I would not trust any p5p feature at all, so nobody is using it.

    But the real problem is that my $_ needs to be supported to use given/when and smartmatch at all. There's no future without it. So as I see it the future of a p5p perl is death by incompetence, not only death by CoC. So there wil…

  • Matt S Trout (mst) commented on The removal of the lexical topic feature in 5.24

    The _ prototype failed to be adopted long before the experimental pragma arrived on the scene, much though I guess that doesn't fit the desired narrative.

    I find it fascinating that in spite of reini's assertions to me on Twitter earlier that he always focuses on technical aspects first, once again the actual technical questions in this thread have been entirely ignored by reini in favour of further long form personal attacks. One might postulate that this tendency to insult and ignore attempts to engage in technical argument on the merits is a more parsimonious explanation of his ex…

  • Aaron Crane commented on The removal of the lexical topic feature in 5.24

    Reini,

    You have been told before that personal attacks are not welcome here. I am no longer willing to provide a platform for you to publish them, and as of today, I am therefore disabling your user account here. This is a permanent action; it will be in place for as long as I am directly involved with blogs.perl.org.

    To be clear, this is not censorship: there are plenty of other places where people can blog without relying on blogs.perl.org. In addition, I will, if you choose, provide a 301 redirect from your existing posts here to another site. If you wish to take me up on …
