Git Perl Programming

How fast my git repositories are growing?

August 6, 2011 – 12:36 pm

I wrote a very small utility to gather LOC counts from a git repository. Called gitsloc, it’s based on Cloc, with some extra goodness provided by Sysadm::Install (a rather inaptly named module, if you ask to me, but full of useful gems).

I guess it could actually have some uses, who knows?, but I wrote it mostly because I wanted to see how fast repos are growing, and R is the obvious tool to tinker with the results.

I’m less than a beginner with R, and I have to admit plotting data from a multi-column CSV file is less straitghforward than I expected: I had to use xyplot from the lattice package, like this:

xyplot( 
  Perl + Bourne.Shell ~ 1:nrow(sloc), 
  data = sloc, 
  type = 'a', 
  auto.key = list( space = "top", lines = TRUE, points = FALSE)
)
view raw gistfile1.r This Gist brought to you by GitHub.

Here the result, with data provided analysing the Dancer github repository (branch devel).

Perlish plans for 2011

Besides the Music Hack Day in Cannes, there are some events I will focus on in 2011:

  • The Italian Perl Workshop. This year, for a change, we will be in Turin. The conference will be held on September 8-9, with my Introductory Perl Class the day before. I’m linking the material for last year’s class, but I have slightly different ideas for the incoming version.
    I would like to go faster on basic syntax – spending a reasonable amount of time dispelling doubts about data structures, which proved to be useful – and to present Moose as “the way you should do OOP in Perl”, probably mentioning the old way as historical curiosity.
  • In the middle of August there will be YAPC::Europe, in Riga. It may seem odd to say that in January, but I’m looking forward for a climatic detour from the hot days we’re likely to have in Spain. And it will be great to meet friends and Perl hackers, as usual.
  • For the past two years I missed the London Perl Workshop. I think its single day model works very well and should be copied more avidly. And I love to spend time in London.

IPW2008 – Idee per talk

March 29, 2008 – 7:17 pm

Non so se quest’anno riuscirò ad essere presente all’Italian Perl Workshop, ma sto lo stesso pensando a quale (o quali) potrebbe essere l’argomento di una mia eventuale presentazione. Ecco le idee avute finora, e che ho già sottoposto al vaglio della mailing list:

  • Movable Type Open Source (20 minuti)
    Six Apart ha intrapreso il progetto di una versione opensource di Movable Type, basata sulla versione 4 di MT. Quali sono le novità della piattaforma, come contribuire, perchè (e perchè no).
  • Tecniche di debugging (20-50 minuti)
    Tutorial su tecniche e trucchi per il debugging in Perl. Come sfruttare a proprio vantaggio le feature più dinamiche di perl.
  • “Non è mai troppo tardi” (20 minuti)
    Adozione di best practice là dove prospera il lato oscuro. Come pagare il debito tecnologico senza l’aiuto di Bono Vox. Storia di un sopravvissuto.
  • Marketing Perl (10-20 minuti)
    Come può funzionare il marketing di Perl? Ha senso? Chi lo sta facendo? (con scampoli della versione 2008 di “Perl.it wants you!”)
