Book Report – December 2014
As you may be aware, I'm writing a book which will eventually become a free e-book. This is my third report on how I'm getting along….
Year: 2014
Quick post-LPW roundup
I've just arrived back from the London Perl Workshop. Lots of very interesting stuff. A big thank you to the organizers! I especially liked: Extending Syntax – Functional Programming meets Macros by LanX; The Internet of Personification by Matt S…
Book Report – October 2014
This month has been quite a busy one for me, so I haven't had much chance to work on my (in-progress) book. However, I have had some time to start work on a short talk for London Perl Workshop 2014…
Exporter::Tiny nearing 1.000000
Yes, in my warped mathematics, 0.042 is nearly 1.000000. Exporter::Tiny is a module I split out of the Type::Tiny distribution. It's an exporter, offering roughly the same capabilities as Sub::Exporter, but with a lighter footprint. I've not massively promoted it,…
Planet Moose – September 2014
Welcome to Planet Moose, a brief write up on what's been happening in the world of Moose in the past month, for the benefit of those of you who don't have their eyes permanently glued to the #moose IRC…
Book Report – September 2014
As you may be aware, I'm writing a book which will eventually become a free e-book. (Oh how I'm beginning to hate the e- prefix on everything vaguely related to computers. Or should I call them e-machines?) This is my…
Object::Util
I've recently released a new module called Object::Util to CPAN. This is a set of handy methods for working with classes and objects in Perl. It is inspired by Safe::Isa, a module which takes advantage of the fact that coderefs…

Woolly & Tig “Going to School”
Oh man, I can’t believe I missed the latest Woolly & Tig special. It was apparently broadcast the same day we went off on holiday.
Data::Dumper Debugging
I've never really used the Perl debugger much (maybe I should learn?) and usually resort to lots of use Data::Dumper; print Dumper($somevar); statements to help me understand what's going wrong with a piece of code. However, what I often find…
Type::Tiny Tricks #7: Tricks with Dicts
In Perl, hashes are typically used for two sorts of purposes: maps (where the hash key acts as an object identifier) and dictionaries (where the hash key acts like a field name). A quick illustration of what I mean…
Type::Tiny Tricks #6: Tricks with Tuples
Let's say you want an attribute to accept a pair of numbers – perhaps a geographic co-ordinates [ 50.873, -0.002 ]. You could constrain the attribute as ArrayRef[Num], but that would accept an arrayref containing a single number, or…
Type::Tiny Tricks #5: Wrapping Moose/Mouse Type Constraints
So you have this Moo class, and it turns out what you really need for it is the StrictVersionStr type constraint defined in MooseX::Types::Perl. You could switch the class to Moose, but long term you want to stick with…
