    New version of the IntelliJ IDEA Perl5 Support plugin has been released:

    • Implemented constants resolution, auto-completion and highlighting
    • Performance improvements: parser, methods resolution, subs and methods autocompletion.
    • Implemented scalar type detection on assignment to sub or method call (sub or method must be annotated to make this work).
    • Implemented C3 mro and fixed bug with DFS.
    • Postfix livetemplates moved to separate group 'Perl5 postfix' to be able to utilize same abbreviations.

    We added support for Perl 6 to ctags. Give it a shot: grab a copy from GitHub.

    C::Blocks—embeding a fast C compiler directly into your Perl parser—looks exciting to me. I hope it will be interesting to some of you and since this is a project in its infancy maybe even inspire participation from the C-monk(ey)s here. Google groups notice:!topic/perl.xs/35CgBxWmqEk; github repo:

    I have no involvement but have had some pain in the past trying to do XS so I welcome anything that makes embedded C, or even just playing with it from Perl, easier.

    New version of the IntelliJ IDEA Perl5 Support plugin has been released:

    • Improved simple variable cast parsing.
    • Added $class as implicit pointer to this.
    • Implemented Mojolicious templates parsing.
    • Implemented pretty dumb Mojolicious autocompletion: default helpers and tag helpers.
    • Implemented embedded markers matching.
    • Fixed problem with caret re-setting on hitting enter in here-doc with injection.
    • Fixed bug with integer numbers highlighting.
    • Enabled quote handler template files.
    • Added Darcula color settings (by Sergey Vardanyan).
    • Moved to Java 1.6.
    • Added three new here-doc injection markers:
      • PERL5 - Perl5 itself. Can you deal with this?
      • MOJO - Mojolicious templates
      • EPERL5 - Embedded perl.

    New version of the IntelliJ IDEA Perl5 Support plugin has been released:

    • Numerous performance optimizations and bugfixes: lexer, parser, auto-completion and methods resolution.
    • Object methods resolution and auto-completion is here now. Only default perl MRO currently implemented. At the moment works for explicitly typed variables and annotated subs.
    • Typing -> or :: is now opening an auto-completion pop-up.

Releasing Perl::ToPerl6 this weekend to CPAN

    The current code is on github under, but will change names upon release.

    It's a configurable Perl5-Perl6 translator tool based heavily on Perl::Critic. You can use your own .perlmogrifyrc file to configure which translators you want to run, and eventually add and configure your own translators.

    While I won't say that it compiles Perl5 to syntactically correct Perl6 100% of the time, I've tested it on DamianWare(tm), and with minimal intervention (changing package declarations, rewriting local *OUT mostly) 99% of Parse::RecDescent passed its compile-time check.

    While most of the changes it does are trivial, they can be hard to get right. For instance, =~ is now ~~, ~ is now ^?, . is now ~, and -> is now .. Go ahead and figure out the right order to do those changes in vim or emacs, I'll wait for you. :)

    In the meantime, it also changes your for() loops around, tidies map and grep, cleans up your filehandles, and changes your sigils from $x[0] to @x[0] like you've always secretly wanted to do.

    As of release here's what it'll do:

    • Add whitespace where needed - if(1), my($x), for(@z), qw(), qx()
    • Translate non-decimal numbers: 0x12f, 0b1101, 017
    • Properly interpolate numbers: \x{263a}, \N{LATIN LETTER CAPITAL X}
    • Fix rational numbers: 32.
    • Reformat here-docs: <<_EOF_;
    • New Q operators: qw(), qr(), qx()
    • Reformat strings: "\ua $hash{key}1 ${foo}"
    • Print to filehandle: print FOO 43;
    • C-style loops: for($i=0;$i<5;$i++)
    • Perl-style loops: for my $x (@a)
    • First-order expressions: map s/foo/bar/, keys %x
    • Basic operators: !$a, $x . "foo"
    • Package usage: use Foo;
    • Constant declarations: use constant FOO => 1, Readonly my $FOO => 1
    • Basic variables: $x->[3], @{ $x }, $x[2]++
    • Special variables: @+, STDOUT, @ARGV
    • Regular expressions: s/foo/bar/igx
    • Sub prototypes: sub foo($)

swat - Simple Web Application Test ( Tool )

    As devops I update a dozens of web application weekly, sometimes I just have no time sitting and wait while dev guys or QA team ensure that deploy is fine and nothing breaks on the road. So I need a tool to run smoke tests against web applications. Not tool only, but the way to create such a tests from the scratch in way easy and fast enough. So this how I came up with the idea of swat.

    Howdy Monks,

    After over 2.5 years of work, I'm very proud to (finally) announce the full release of RPerl v1.0 on CPAN!

    Installation should now be as simple as:

    $ cpan RPerl
    $ cpanm RPerl

    For more information about install options, please see:

    As outlined in step 3 of the install notes file, we can now automatically compile our test program and see speed improvements of approximately 170x to 350x, depending on your system.

    For detailed usage of the rperl command, please see the POD.

    As usual, the RPerl technical team is in #perl11 on so don't hesitate to reach out if you need help or have any questions. Let the bug reports begin! :-)

    We've come a long way, and we've got a long way to go yet, this is just barely the beginning!

    ~ Will the Chill, &

    Perl5 release 22.0 is now available

    “You are the advocate of the dead.” The old man nodded. “I am. People talk about being fair to this one a +nd that one, but nobody I ever heard talks about doing right by them. We take ever +ything they had, which is all right. And spit, most often, on their opinions, whic +h I suppose is all right too. But we ought to remember now and then how much of w +hat we have we got from them. I figure while I’m still here I ought to put a word +in for them.” -- Gene Wolfe, Citadel of the Autarch

    We are excited to announce Perl 5.22.0, the first stable release of Perl 5, version 22.

    You will soon be able to download Perl 5.22.0 from your favorite CPAN mirror or find it at:

    SHA1 digests for this release are:

    400338c91c56420d98142cbfcb84d418cae2c98c perl-5.22.0.tar.bz2 e4c9e40d18efa7368e77343e0fd3339ca87e34f8 perl-5.22.0.tar.gz f40ad10d0b0e798efafebd9dc5d6509df2af3f1e perl-5.22.0.tar.xz

    You can find a full list of changes in the file "perldelta.pod" located in the "pod" directory inside the release and on the web.

    Perl 5.22.0 represents approximately 12 months of development since Perl 5.20.0 and contains approximately 590,000 lines of changes across 2,400 files from 94 authors.

    Excluding auto-generated files, documentation and release tools, there were approximately 370,000 lines of changes to 1,500 .pm, .t, .c and .h files.

    Perl continues to flourish into its third decade thanks to a vibrant community of users and developers. The following people are known to have contributed the improvements that became Perl 5.22.0:

    Aaron Crane, Abhijit Menon-Sen, Abigail, Alberto Simões, Alex Solovey, Alex Vandiver, Alexandr Ciornii, Alexandre (Midnite) Jousset, Andreas König, Andreas Voegele, Andrew Fresh, Andy Dougherty, Anthony Heading, Aristotle Pagaltzis, brian d foy, Brian Fraser, Chad Granum, Chris 'BinGOs' Williams, Craig A.

Golden, Graham Knop, H.Merijn Brand, Herbert Breunung, Hugo van der Sanden, James E Keenan, James McCoy, James Raspass, Jan Dubois, Jarkko Hietaniemi, Jasmine Ngan, Jerry D. Hedden, Jim Cromie, John Goodyear, kafka, Karen Etheridge, Karl Williamson, Kent Fredric, kmx, Lajos Veres, Leon Timmermans, Lukas Mai, Mathieu Arnold, Matthew Horsfall, Max Maischein, Michael Bunk, Nicholas Clark, Niels Thykier, Niko Tyni, Norman Koch, Olivier Mengué, Peter John Acklam, Peter Martini, Petr Písař, Philippe Bruhat (BooK), Pierre Bogossian, Rafael Garcia-Suarez, Randy Stauner, Reini Urban, Ricardo Signes, Rob Hoelz, Rostislav Skudnov, Sawyer X, Shirakata Kentaro, Shlomi Fish, Sisyphus, Slaven Rezic, Smylers, Steffen Müller, Steve Hay, Sullivan Beck, syber, Tadeusz Sośnierz, Thomas Sibley, Todd Rinaldo, Tony Cook, Vincent Pit, Vladimir Marek, Yaroslav Kuzmin, Yves Orton, Ævar Arnfjörð Bjarmason.

    The list above is almost certainly incomplete as it is automatically generated from version control history. In particular, it does not include the names of the (very much appreciated) contributors who reported issues to the Perl bug tracker.

    Many of the changes included in this version originated in the CPAN modules included in Perl's core. We're grateful to the entire CPAN community for helping Perl to flourish.

    For a more complete list of all of Perl's historical contributors, please see the AUTHORS file in the Perl source distribution.

    We expect to release perl v5.22.1 in about a month, give or take. The next major version of Perl 5, version 24.0, should appear in May 2016.

    The first release of Perl 5's sister language, Perl 6, is expected around Christmas 2015.

on May 23, 2015 at 04:09 have published a new blog entry:

    "A recent hackathon provided us the opportunity to investigate speeding up integer allocation in the Perl interpreter. If successful, this could optimize nearly every program we run. We discovered that a naive implementation could work, but would make the code a lot more difficult to maintain. Our path lead us to attempt to leverage the C preprocessor to improve code clarity while opening doors to real gains in program execution speed."
