• Posted Call for FOSDEM 2020 Booth volunteers to DrForr

  This year we've got one of the high-traffic locations, on the ground floor where Free Software Foundation Europe set up last year, right next to the stairway to *all* the dev rooms. So we're looking for volunteers to come and talk about both Perl and Raku at FOSDEM 2020 in Brussels. If I haven't…

• Posted Rewriting Perl Code for Raku Part V is out to DrForr

  Part V of the series is out, this time more in-depth discussions of the pack() method in Raku and Perl

• Posted Rewriting Perl Code for Raku IV: A New Hope to DrForr

  Part IV starts to get into the heart of OLE::Storage_Lite by covering the pack/unpack builtins.

• Commented on Rewriting Legacy Code in Raku III: The Sourceror
  My fault. I've removed that, thank you for drawing your attention to that point....
• Posted Rewriting Legacy Code in Raku III: The Sourceror to DrForr

  Part III in the series talks about functions, prototyping, and some of the tweaks you'll need to make while transferring Perl code to Raku

• Posted Rewriting Legacy Code in Raku to DrForr

  I'm already working on Part II, but here's Part I in all its glory: http://www.theperlfisher.com/index.php/2019/11/24/rewriting-legacy-code-for-raku/ - I'm writing OLE::Storage_Lite from the original Perl 5 source, and this article series is my thoughts on the process so far.

• Posted 3 Weeks left to sign up for the Perl 6 Tutorial course at TPC in Glasgow to DrForr

  Be ready for all the new Perl 6 content at the Glasgow Perl Conference, join me at the day-long Perl 6 Tutorial session on Monday the 13th, get trained before the talks start!

• Posted Perl6 Readline update to DrForr

  A long time coming, this looks along /usr/lib64 and /lib/x86_64-linux-gnu for existing libreadline.so.* libraries, otherwise assumes v7. I'll add more directories as I find them, and make sure that it looks recursively in /lib if all else fails as part of the next release. I'll be adding comments…

• Posted Perl 6 Training at TPC - Salt Lake City to DrForr

  After TPC join me for The Hitch-Hiker's Guide to Perl 6 at The Little America in Salt Lake City.

• Posted ANTLR4::Grammar v0.1.0 to Perl 6 CPAN to DrForr

  ANTLR4::Grammar lets you convert ANTLR4 lexer and parser grammars from ANTLR to Perl 6. It currently works with all of the basic EBNF constructs, and for the moment chooses to ignore the features of ANTLR that the native Grammar type doesn't support. When I've added the basic Action class I'll…

• Posted Abusing Multiple Dispatch in Perl 6 for fun and profit to DrForr

  Abusing Multiple Dispatch Creatively is avallable on my blog for perusal. Comments and questions welcome as always.

• Posted Simple tree walking in Perl 6 to DrForr

  Check out Tree Surgery for a quick guide on how to easily walk generic trees of Perl 6 data.

• Posted DRYing your Perl 6 tests to DrForr

  Ah, the joys of conference-driven development. DRYing your Perl Tests is now out, probably going to be a series, maybe even a book. It's just a quick take on refactoring test suites in Perl 6. Maybe it goes too far, but…

• Posted Perl 6 Training August 8th at TPC::Amsterdam to DrForr

  The official training schedule is still being drawn up, but I'm pleased to offer a full day of Perl 6 training at the b.amsterdam venue the day before TPC::EU . Please feel free to join me in a day of hands-on interactive learning about Perl 6. If you were at the Perl 6 training…

• Posted You won't believe this one quick Perl 6 optimization hack! to DrForr

  Now that I've alienated half the crowd, here's the scoop. Perl6::Parser has a fairly extensive test suite, which I run on my laptop inside an Ubuntu 14.04 VM - it's the latest version I can find that supports seamless integration, though I'm considering completely dumping the GUI and going with…

• Commented on Perl6::Tidy initial release
  Thanks! It currently supports the basic 1-true-brace-style, Whitesmiths, Allman, GNU and a few others that aren't so common....
• Posted Perl6::Tidy initial release to DrForr

  Perl6::Tidy has been released to GitHub, not on the ecosystem yet. The driver program is 3 lines, mostly passing options to the tidier. Which is 6 lines, doing the real grunt work.

  It doesn't do much yet, but it's pure Perl 6.

• Posted Perl6::Parser available for Perl 6 to DrForr

  It’s by no means complete, but it’s available for trial from your friendly neighborhood Panda installer. This tool uses Perl 6’s own internal parser in order to generate a parse tree for Perl 6 code, and has enough information to reconstruct the original Perl 6 source,…

• Posted From Regular Expressions to Grammars (in Perl 6) Part IV to DrForr

  The fourth and final installment of the Perl 6 regular expression -> grammars tutorial has hit the blog: From Regular Expressions to Grammars, Part 4

• Commented on Focussing Haskell on Perl 6
  I don't see why not. I was just after the visual metaphor of light rays coming through a lens, but :: seem less confusing. The module itself is on hiatus while I get a few other things done, but that's...
• Posted Part 3 of Perl 6: Regular Expressions to Grammars to DrForr

  Part 3 of the Regular Expressions to Grammars tutorial is now up at http://theperlfisher.blogspot.nl/2016/02/from-regular-expressions-to-grammars-pt_20.html - This covers parsing of a short JavaScript blurb into a form that the compiler we're going to write next time can understand.

• Commented on Perl 5 Optimizing Compiler, Part 18: RPerl v1.6 Released, Happy Valentine's Day!
  Hey guys, do what you can to upvote this proposal for TPF. It's about the only really "new" Perl5 thing to come along in a while. CPAN has plenty of modules, it's about time for a new, shinier implementation....
• Posted From Regular Expressions to Grammars (in Perl 6) Part II to DrForr

  Part 2 of my Regular Expressions to Grammars tutorial is now up at The Perl Fisher. The previous part covered the basic metacharacters, this…

• Posted Part 1 of a tutorial on Perl 6 Regular Expressions and Grammars to DrForr

  On my blog at The Perl Fisher - Part II coming next week, or whenever I get vectors and lists working in Inline::Scheme::Guile.

• Commented on Focussing Haskell on Perl 6
  I don't know if this library is in the true spirit of the Haskell original, but it feels close. The Haskell library is all about treating Lenses as data types and composing those into different lenses. It might be worth...
• Posted Focussing Haskell on Perl 6 to DrForr

  On the bus ride out to Charleroi I caught a stray brainwave about how to properly notate at least some of Haskell's Lens library, so I wrote up some notes on it. This is going to be slightly spooky, but not much more than the previously-existing ability to bind one data…

• Commented on Introducing Scheme in Perl 6
  I've renamed it to Inline::Scheme::Guile in case anyone wants to do Racket or SIOD or something after me. Also, multiple values now work, so: is-deeply [ $g.run( q{(values 3 2 1)} ) ], [ 3, 2 1 ]; passes. I'll...
• Commented on Introducing Scheme in Perl 6
  Or I just need to use the appropriate scm_$type_p predicates. Strings need dynwind-protect in order to not leak, and I've partially figured out list return values. It'll probably eventually look something like: my @out = Inline::Guile.run(q{'(a "b" 3)}); is-deeply \@out,...
• Posted Introducing Scheme in Perl 6 to DrForr

  Introducing Scheme in Perl 6: https://github.com/drforr/perl6-Inline-Guile

  This is very much in its early days, and the interface is likely to change as I find the method(s) in the Guile library that I need. Specifically once I can figure out how to portably crack into a SCM return value t…

• Yary commented on Focussing Haskell on Perl 6

  I like the concept, but can the syntax be made to look more like the binding operator and less like a comparison? eg
  

  
  
  $a :< $lens >: $b; # Either side triggers change in other
  
  $a << $lens >: $b; # $b changes when $a does
  
  $a = 'foo bar'; is-deeply $b, [ 'foo', 'bar' ]; # ok 1
  
  $b.[0] = 'moo'; is-deeply $b, [ 'moo', 'bar' ]; is $a, 'foo bar'; # ok 2, ok 3
