Merry Christmas and Happy Holidays fellow Monks!

I've released v1.30 of berrybrew as a Christmas gift to our Windows Perlers.

It's a significant release, here's a list of the most noteworthy additions:

• Added a UI, runs out of the System Tray, allows installing, removing and switching Perls using a button
• Added new associate command, allowing berrybrew to manage .pl file associations
• Added berrybrew-refresh command, to be run after switching perls. No more having to re-open command line windows
• If a newer point release of a major version is introduced, we now seamlessly integrate installed previous point-releases into the Perls available
• Configuration options are now based in the Windows Registry
• Added new options command, allows changing configuration options at runtime
• We now supply a bb command, which is simply a short-hand form for berrybrew
• Greatly enhanced the self-extracting installer
• Much more precise handling of the PATH environment variable
• More graceful handling of exceptions
• Added info command which displays various internal directory path information
• Added new hidden/developer commands

Please have a read of my blog post for the full announcement details.

Cheers!,

I'm not sure how long this has been the case, but the metacpan page for Devel::NYTProf currently lists it as up for adoption.

This is a key module for perl development, so hopefully someone with the right skill set is willing and able to pick it up.

Type::Tiny 1.8.0 (1.008000) was released today.

• Type::Tiny 1.8.0 on MetaCPAN
• Type::Tiny website (NEW!)

The new features are pretty minor. Most of the improvements are in documentation and testing.

• Totally rewritten manual/tutorial.

• Every issue on RT has been handled.

• Bigger test suite. The exact number of tests run varies based on the availability of optional dependencies, but I just ran the test suite with EXTENDED_TESTING set to false and most of the optional dependencies installed, and it was nearly 7500 tests, compared to just over 2700 for Type::Tiny 1.6.0. With EXTENDED_TESTING true, there are nearly 13900 tests.

  This includes a set of tests for each built-in type which are intended to function both as test cases and advanced documentation.

It's that time of year folks:

• http://www.perladvent.org/2019/
• I'll add more when/if I find them.

The official Perl documentation site at https://perldoc.perl.org was recently overhauled. Independently, I put together a reimagined documentation site that would be hosted at https://perldoc.pl. In the interest of providing a documentation site that best serves the needs of the Perl community, we need your feedback. Please give both sites a try, in-depth if you want, or just how you would most commonly use the site. What do you like about the design or the functionality of each site? What is missing or can be improved? Any feedback regarding what you want from the Perl documentation site is helpful and appreciated. Please leave comments here or in the linked posts by Monday Nov 18th.

MooX::Press is a quick way of building a bunch of Moo roles and classes in one use statement.

The most basic example would be:

  package MyApp {
    use MooX::Press class => ['Foo', 'Bar'];
  }
  
  my $thing1 = MyApp::Foo->new();
  my $thing2 = MyApp->new_foo();   # alternative constructor
[download]

But do-nothing classes with a constructor and nothing else aren't very exciting. Let's define a class with some subclasses which have attributes and roles and methods and stuff.

  package MyApp::Zoo;
  use MooX::Press (
    role => [
      'Aquatic' => {
        can => [
          swim => sub { print "swimming\n" },
        ],
      },
      'Flight',
    ],
    class => [
      'Animal' => {
        has => [qw( $name $colour $age )],
        subclass => [
          'Fish' => {
            with => 'Aquatic',
            subclass => [qw( Shark Ray )],
          },
          'Bird' => { with => 'Flight' },
          'Mammal' => {
            subclass => [
              qw( Panda Goat ),
              'Kangaroo' => { can => [ jump => sub { ... } ] },
              'Dolphin'  => { with => 'Aquatic' },
              'Bat'      => { with => 'Flight' },
            ],
          },
        ],
      },
    ],
  );
[download]

The above code just defined the following roles:

• MyApp::Zoo::Aquatic
• MyApp::Zoo::Flight

And the following classes:

• MyApp::Zoo::Animal
• MyApp::Zoo::Fish
• MyApp::Zoo::Shark
• MyApp::Zoo::Ray
• MyApp::Zoo::Bird
• MyApp::Zoo::Mammal
• MyApp::Zoo::Panda
• MyApp::Zoo::Goat
• MyApp::Zoo::Kangaroo
• MyApp::Zoo::Dolphin
• MyApp::Zoo::Bat

All with the appropriate attributes and roles applied to them.

Also, it defined a package called MyApp::Zoo::Types with class and role type constraints already set up.

So you can do:

  use Moo;
  use MyApp::Zoo::Types qw(Kangaroo);
  
  has mascot => (is => 'ro', isa => Kangaroo);
[download]

Or:

  use MyApp::Zoo::Types qw(is_Kangaroo);
  
  $thing->jump if is_Kangaroo($thing);
[download]

Here's some more code using our zoo classes...

  use MyApp::Zoo ();
  
  my $lenny = MyApp::Zoo->new_shark(name => 'Lenny');
  $lenny->isa('MyApp::Zoo::Shark');    # true
  $lenny->isa('MyApp::Zoo::Fish');     # true
  $lenny->isa('MyApp::Zoo::Animal');   # true
  $lenny->does('MyApp::Zoo::Aquatic'); # true
  $lenny->can('swim');                 # true
  
  package MyApp::Zoo::Enclosure::Tank {
    use Moo;
    use Types::Standard qw(ArrayRef);
    use MyApp::Zoo::Types qw(Aquatic);
    has animals => (
      is  => 'rw',
      isa => ArrayRef[Aquatic],
    );
  }
  
  my $tank = MyApp::Zoo::Enclosure::Tank->new(
    animals => [ $lenny ],
  );

MooX::Press is on CPAN.

The pull request has been merged, and you can read the changes that are supposed to happen here: The Path to Raku

See the thread on Github.

Relevant quote:

I am in favor of this change, because it reflects an ancient wisdom:

“No one sews a patch of unshrunk cloth on an old garment, for the patch will pull away from the garment, making the tear worse. Neither do people pour new wine into old wineskins. If they do, the skins will burst; the wine will run out and the wineskins will be ruined. No, they pour new wine into new wineskins, and both are preserved.”

I am over the moon: Spreadsheet::ReadSXC got a new maintainer, and it is someone we all trust: Corion.

He'll start refactoring this old beast and try to get it leveled up to the quality we know of Spreadsheet::ParseExcel and Spreadsheet::ParseXLSX.

Corion, don't feel the pressure :) but my hopes are high. Willing to give every cycle a test spin. Go man!

Personally I subscribe to the idea of making it a submodule of a new Spreadsheet::ParseODS to make module-name-guessing easier.

In case you missed it Task::Kensho needs your help!:

"CPAN is wonderful and it is vast. Task::Kensho offers a curated look at the best it has to offer for those who don't know what to look for. But to remain useful, it must keep up with the trends of CPAN and the community. Thus, the community's input is vital to its maintenance.

"Please, take a moment and look through the open issues. Comment or add a reaction in support of changes that make sense to you, and open a new issue if you think something is missing."

Nothing like a long hospital stay after a severe head injury to get caught up on some project work.

I've released version 1.26 of berrybrew.

See my blog post for more information, and an example of the new berrybrew virtual command.

TL;DR

• berrybrew virtual allows you to manage non-Strawberry external Perls
  
  
• Unattended installations now possible
  
  
• new quick argument to berrybrew switch allows switching to new Perl instances without opening a new CLI window
  
  
• berrybrew module export and berrybrew modules import allows you to export and import modules between Perls. Custom module list files allowed
  
  
• Ability to change between Strawberry's home directory and Windows home directory when using File::HomeDir
  
  

Long version:

• Management of external Perl installations; Using the new berrybrew virtual command, one can bring in other installations of Perl for management under berrybrew. For example, if you have an ActiveState Perl installed on the system, you can virtualize it under berrybrew, and use or switch to it just like any of the portable Strawberry Perls we normally manage. This means that you can switch over to your system Perl when needed, without having to modify PATH, or temporarily disabling berrybrew
  
  
• Unattended installations are now possible. We no longer prompt for user acceptance when running the initial configuration
  
  
• New quick argument to berrybrew switch; This allows you to switch to a different Perl instance persistently without having to close the existing CLI window and opening a new one (note: some binaries and features may not work correctly. If you run into problems, simply open a new window)
  
  
• Export and import modules from one Perl instance to another; berrybrew modules export and berrybrew modules import will dump a list of all installed CPAN distribution names from one Perl and install it on others. The export files can be edited at will before re-importing, and you can even create your own module list files to use as you see fit. Using this feature, in conjunction with berrybrew clone allows you to easily set up template Perl instances for very quick Perl platform setup
  
  
• Ability to change the location where File::HomeDir points to; you can switch between the Windows home directory location, or the default location that Strawberry Portable editions set
  
  

Side note... a request came in by a user to support previously installed Perls. Their developers use berrybrew, but all of their CI happens automatically on a locally installed Active State Perl. They wanted a way to be able to use Active State for their testing pipeline, without having to muck with path environment variables and such that would mess up the developer environment. With berrybrew use virtual_instance, the system Perl can be used for the CI runs without affecting the rest of the system.

So excuse me just forwarding the German announcement, before delaying it till I have an appropriate translation.

(just run it thru google translate if necessary.)
