"I can now use Perl 5's DBI in Perl 6 :)"

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

    The feature this post is about is just a few days old. It doesn't yet destroy P5 objects, there's more marshaling work to do, etc.

    Update About one month after nine started this project... A destroy that makes sense in the context of P6 has been implemented. (But note ribasushi's point about a ref-count driven destroy.) Marshaling is done, including marshaling of exceptions. There's support for inheriting from Perl 5 classes in Perl 6. It already covers a lot of P5/P6 interop functionality.

    (I'm bringing this project to monks' attention at this very early stage in the hope that at least some of you consider joining the freenode IRC channel #perl6 over the next couple days to encourage P6ers, play with this new P5 interop, ask questions, etc. Here's hoping.)

    Stefan Seifert (aka nine or niner) did a lightning talk at YAPC::EU and started the Inline::Perl5 repo 4 days ago.

    He's been making rapid progress since then.

    Yesterday in #perl6 niner wrote "I can now use Perl 5's DBI in Perl 6 :)".

    Update "I'm out of ideas. Now I need some real world usage of Inline::Perl5 to find out what's missing.".

    At the time of writing this PM post the repo's readme says:

    Module for executing Perl 5 code and accessing Perl 5 modules from Perl 6.

    Supports Perl 5 modules including XS modules. Allows passing integers, strings, arrays and hashes between Perl 5 and Perl 6. Also supports calling methods on Perl 5 objects from Perl 6.

    Update README now adds "and calling methods on Perl 6 objects from Perl 5."

PerlWizard - A free wizard for automatic Perl software code generation using simple forms

    PerlWizard at quickly generates front ends for user-friendly Perl scripts for Unix and Windows, with emphasis on the user interface, managing defaults files, and providing help. The generated user interface supplies defaults for unentered options, validates options, and records options for use as defaults on subsequent runs of the generated scripts. This makes PerlWizard scripts much more interactive and friendly than typical command line programs. Once PerlWizard generates the front end, the programmer just needs to go to the bottom of the generated code and start writing.

    No need to worry about how to set up Getopt::Long calls, initialization files, built-in help, log files, etc.

Rakudo Perl 6 and MoarVM Performance Advances

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

    Jonathan Worthington has just delivered a presentation at YAPC::EU discussing Rakudo performance work over the last 12 months. There's a video of the talk and slides.

    The presentation includes a look at benchmarks comparing a recent Rakudo (on MoarVM) with the 2013.08 release of Rakudo (on Parrot) and Perl 5 v20. I'm curious what folk make of the numbers on page 76.

    He also revealed a new profiling tool. Update: Here it is profiling some P6 code.

    If any readers have tried Perl 6 but found it too slow, now might be a good time to try again; you should find that it's a lot faster than it was, and if it isn't fast enough for your use case it's now a lot easier to both see what's making it slow and to make it faster.

Project Euler Returns

    Project Euler members will be glad to know that it has now recovered from the June 20 security breach, and users can again access their accounts. (Be prepared to change your password on the initial login.) For those not familiar with Project Euler, it provides:

    a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

    The site is language-neutral, but I have found Perl to be an excellent language for tackling the problems; and, of course, the challenges are a useful way to practice one’s Perl skills.

CPAN Day - 16th of August

    Ask not what CPAN can do for you, ask what you can do for CPAN. CPAN day falls on the 16th of August. What is CPAN day? The anniversary of the first "true" module upload to CPAN, on the 16th August 1995, and a call to arms for bug fixes, releases and other contributions.

    A nice idea, considering that (at time of writing) there are 501 pages of issues on RT (yes, I appreciate many of these are very old or for modules which no longer exist).

    See also The ghost of CPAN days past.

    Update: that should have said 501 pages of issues.

    Update 2: /paves/pages/.

New module announcement: AntTweakBar

    Hello dear monks!

    It seems, that there was no any GUI library for perl/SDL. Now it's fixed a bit :)

    I'm glad to announce perl5 bindings to AntTweakBar!

    AntTweakBar is a tiny GUI library for OpenGL/SDL/DirectX application. There is no any complex dialogs, alerts, widgets etc., but a small key-value tabular window, with possibility to display/enter text, number, list of strings, checkbox and button; more exotic possibilities of it are: colour choosing widget, 3D-vector and even quaternion rotation choose/display widgets.

    Perl bindings to AntTweakBar are available on CPAN here. There is corresponding alien package, so there is no need worry how to install original C-library into system.

    I've got successful test reports on FreeBSD, Linux, Darwin and Win32 (strawberry perl).

    Patches, feature requests, code critique or documentation fixed would be welcome. Thanks for your attention!

    WBR, basiliscos.

[Win32] PDL being shipped with Strawberry Perl-5.20.0

    For those interested, there are now 32 bit and 64 bit releases of Strawberry Perl 5.20.0 (portable) that ship with PDL.
    These distros are listed at

    Also included in these editions of Strawberry Perl are a number of libraries that are needed for building additional PDL::* modules.
    Specifically, those libraries are fftw3, gnuplot, gsl, hdf4, hdf5, plplot, proj, szip, talib, netcdf, and lapack.

    kmx's intention is to provide these builds for the 5.20.x releases, and then to review whether it's worth his trouble to continue to provide them.
    So I think it's a good idea for those Windows users interested in using PDL to get behind these distros .... otherwise they may be discontinued.


    PS: As a side note, my PPM packages for PDL (and other modules) for perl-5.20 have not yet been built, but should become available over the next week or so.
