    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

    I've applied for a grant from The Perl Foundation — see Grant Proposal: Modern Object Oriented Programming in Perl.

    If you'd like to support the application, please comment on TPF's blog. Alternatively, if you have any queries or concerns about the application, comment on the blog, or indeed here, or even /msg me on PerlMonks or IRC, and I'll do my best to address them.

New free TTF font for coding: Camingo

    I am enjoying a new monospaced font for coding my Perl using Textpad in Windows; it's called Camingo and it's available for free at, where you can see a demo. It has a very clear distinction between "1" and"l", a slashed zero, and a clean look I find very pleasing. The designer/publisher -- Jan Fromm -- calls it a "type family for programmers." I think they'd be OK with my pasting in this excerpt from its description:
    A compact appearance and a moderate line height provide for good legibility and make writing code a pleasure. It is based on CamingoMono, but has several specially-drawn glyphs that work well at small sizes, including Q, l, &, *, ~ and #. The stroke weights are relatively light, which makes CamingoCode suitable for both bright and dark visual themes.
Rakudo Star (Perl 6 bundle) now supports MoarVM and JVM backends

    »»» This post is about the immature Perl 6, not the rock solid Perl 5 «««

    Rakudo Star is a "batteries included" distribution that couples the Rakudo Perl 6 compiler with an installer, the C calling interface, bundled modules, and doc.

    The new Rakudo Star 2014.04 release is the first to be shipped with a MoarVM and JVM backend (as well as a Parrot VM backend). This marks the stage where not only is the Rakudo compiler on the MoarVM and JVM backends passing more spectests than on the Parrot backend but also the ecosystem -- installer, modules, doc -- has generally caught up too.

    The biggest impact so far of including these new backends is on performance, use of concurrency1, and use of Java code2.

    Rakudo on Parrot is currently fastest for code that does a lot of string slicing and dicing. This is Rakudo on Parrot's main current advantage, one it's likely to retain for another few months. Ignoring that, Parrot is much slower for most scripts and the Rakudo/NQP backend does not support concurrency.

    Rakudo on MoarVM runs most P6 scripts a lot faster using a lot less RAM than either Rakudo on Parrot or Rakudo on JVM. Concurrency is supported, though not as robustly as on the JVM.

    Long running scripts sometimes end up running a lot faster on the JVM backend than on either MoarVM or Parrot due to JVM's JIT. The JVM also supports P6's concurrency features and calling Java libs.

    Finally I'd like to highlight the debugger and its command line UI. Partly because it's a good tool, but mostly to illustrate how easy it can be to contribute to the core as I did via a bugfix and a speedup.

    1 Reactive programming in Perl 6 is a good intro to P6's reactive programming features but make sure to use the latest version of the example code in the reactive examples code repo.

    2 See jnthn's examples of calling Java code.

App::cpanminus updated

    Hi all,

    a long awaited update on App::cpanminus happened yesterday.

    You will ask: Why mentioning? The answer: Over months there was a bug which kept me away from using this everyday (and loved) tool with Strawberry Perl. With the change "Bump fatpacked local::lib" it now works the same way I'm used to under Linux. Just installed a very fat package (many dependencies) without problems.

    Thank you Tatsuhiko Miyagawa!

    Hi I thought some fellow monks might be interested in this:
    Date Posted: April 6th, 2014
    Introducing Komodo Personal Licensing

    We are very excited to let you know that (for a limited time only) we are offering a special Personal license of Komodo IDE to individual developers for $89. If the new Personal license is well received it may actually get a permanent place in the Komodo lineup… we're hoping it does! ....
    Seems like a good deal to me. I'll probably buy it as that price!

    Be sure to check out the limitations of this personal license

    Hi all,

    chromatic has announced and published the 2014 edition of his Modern Perl Book.

    I think it's worth mentioning it here. You can find it at .

    Thank you chromatic for sharing your work for free! It would be intersting to see a meta post clarifying the differences to the last edition.

    Best wishes

    Damian Conway gave us a brilliant lecture on Perl6 tonight here near Geneva. I'm already convinced P6 syntax is the smartest at present. I only regret it doesn't benefit the advantages of a fully compiled language.

    See my blog post. Long story short: Type::Tiny's overload of + will go away in the next release; use $type->plus_coercions($coercion) instead.

    This year the DC and Baltimore Perlmongers will be hosting our 3rd DC-Baltimore Perl Workshop! We have up and running -- I just posted the Call for Speakers. Come on over and register, submit a talk, watch for updates, etc.

    The first day, Saturday May 3, will be a 2-track conference on a variety of Perlishness. The second day, Sunday May 4, is a project-athon -- bring a project and share, or don't bring one and others will share with you! :)

    I look forward to seeing some Monks there!
