  • Posted Arango::Tango to Alberto Simões

    I am planning on a new project, and a friend suggested me to look to Arango, as an alternative do Mongo, specially because it includes a graphs query language integrated. As I am not really used to Mongo at all, decided to give it a try.

    Unfortunately I did not find a proper module to use …

  • Posted PRC 2016 - Fouth Semester to Alberto Simões

    This was not just a bad year for musicians. Unfortunately not. And the last three months were busy, with lot of (mostly bureaucratic) work. I was expecting the Christmas day to have some extra-time and do, at least one, a decent PR, but I got sick and the will to program just passed by.

    So…

  • Posted PRC 2016 - Third Trimester to Alberto Simões

    Here I am again making a summary of my work during the third trimester of my second year on the CPAN Pull Request Challenge:

  • For July I got Algorithm-GooglePolylineEncoding. This module did not include a META.json file, so my PR was it generation. It was great to have interac…

    I would say that if you do your usual first subroutine line: sub foo { my ($arg1, $arg2) = @_; ... } you will be safe. But my preferred solution is even better: use feature 'signatures'; Please, SawyerX, make them...

    Dear Sawyer, Sorry. I should probably rephrase the whole post. Or probably now it is a bit too late. For me things weren't that bad. I know you, Ricardo Signes and Paul Johnson enough, to know of your busy lives....
  • Posted PRC 2016 - Second Trimester to Alberto Simões

    This second semester got me modules owned by well known community members. I expected that to make my life easier, namely to prepare more relevant PRs, but unfortunately it did not work that way.

    For April, I got Dist::Zilla. My PR was the documentation of 'Dist::Zilla::App::Tester', but I…

  • Posted PRC 2016 - First Three Months to Alberto Simões

    As last year I was unable to post every month about the Pull Request Challenge assignments, I decided that this year I would try to post updates every three months.

    So, for the first month, I got WebInject. The PR was not huge. Just a contribution to add a README file to the distribution. …

  • Posted CPAN PRC: July is Data::Dump to Alberto Simões

    For July, the CPAN Pull Request Challenge assigned me Data::Dump. Better than the pull request itself, this assignment was great to know Data::Dump, as I have never see it before.

    For the PR, I tried to read user complains, and one suggestion was to keep UTF-8 intact when dumping to a stre…

  • Posted CPAN PR-Challenge: June Report to Alberto Simões

    I know this is getting a lame excuse. But with lack of time, the patch I had time to prepare this month is, again, small. It is mostly some extra tests: https://github.com/szbalint/WWW--Curl/pull/10

    But better few than nothing...

    Somehow I missed to post my April report. Don't remember well what was the PR. It was something basic, as I lack the time for real work.

    I confess I did not notice the difference when looking to the manpage. I though they were just aliases (similar names). But of course, it was my mistake. Nevertheless, still not that good: my $newGloss = $self->{term}->readline(">> ", decode("utf-8", $gloss->{gloss}));...

    Hmms, is there a difference? It seems I have to RTFM. Will say something soon. Thanks....
  • Posted Term::ReadLine::Gnu Unicode Hell to Alberto Simões

    I must be doing something wrong. Surely. I have a REST service. I get data using HTTP::Tiny and use JSON::Tiny to decode it.

    If I try to print to the Term::ReadLine::Gnu OUT filehandle, I get double encoded strings, like this:

  • Posted CPAN PR-Challenge - April Report to Alberto Simões

    This was a busy month in my teaching duties. Also, needed to debug and create pull requests for other projects. Nevertheless, I managed to create a small pull request in the PRC assigned module, Google::ProtocolBuffers Perl implementation.

    The pull request was a validation of the google sp…

  • Posted CPAN PR-Challenge: March Report #2 to Alberto Simões

    The second pull request for this month is, this time, in the distribution that was assigned to me, Exobrain. In this case, it was a simple PR on dependencies.

    First, define the minimum version for Data::Structure::Util, the distribution for which I created my first PR this month, in order …

  • Posted CPAN PR-Challenge: March Report #1 to Alberto Simões

    This month I was assigned Exobrain. My first problem is that I can not install install it at all because dependencies are failing. The first failing dependency was Data::Structure::Util.

    Looking around in Testers Matrix I found that is was failing only on 5.20 or above. Then, looked up the…

    Nevertheless, if meanwhile anybody comments on my Pull Request and sugges…

  • Posted PR-Challenge: January 1st PR to Alberto Simões

    So, yeah, to make me more active in the Perl community I decided to join the Pull Request Challenge. I have a quite big number of modules to maintain, but sometimes it is good to look to some other people code to learn something.

    My attribution for January was Data::ObjectDriver. I am not …

    • Tom Wyant commented on Do not pass perl globals as arguments to subroutines

      Well, maybe this is cargo cult. Back in 2010 I spent quite a bit of time tracking down a problem where I was returning the value of $+[0] from a subroutine, and the caller was not receiving the value that the subroutine returned. The fix was to force the copy by assigning the value to a lexical variable.

      I was never able to figure out exactly what was going on (this was in PPIx-Regexp, it was seen when Perl-Critic called it and I was never able to duplicate the p…

    • KES commented on Do not pass perl globals as arguments to subroutines

      Even this first subroutine line will not save you if you will do some debugger stuff:

      sub process {
      my( $state, $sub ) = @_;
      }

      #somewhere in DB::sub:
      process( $DB::single, $DB::sub );

      Here when &process is called the $DB::sub is changed and $sub will get 'DB::process' instead of original value.
      Same logic is applied when you pass $DB::single, but at DB::DB sub when $^D |= (1

    • Aristotle commented on Do not pass perl globals as arguments to subroutines
      I was never able to figure out exactly what was going on […but…] I have made it a practice ever since

      That is pretty much cargo cult by definition. 😊 Not that I can fault you for reacting the way you did; so might I.

      The fact that a match-related variable was involved makes me suspicious immediately – all of them have various scoping and lifetime oddities for reasons of efficiency and/or DWIM. But who knows if that’s really the issue.

      Problem is, this is a situation like with folk remedies: with no tested model of what was going on, your r…
