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,…

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…

Method Privacy in Perl
This is a slightly expanded version of a comment I posted a couple of days ago on NEILB's blog. Neil was mostly talking about private functions, while I'll be talking mostly about private methods (i.e. object-oriented programming), but I…
Meta-Meta-Meta Problem Solving
OK, so I'm working on a project and some unexpected bug crops up. It turns out to be a bug in a dependency. I could work around it, but… I happen to maintain the dependency, so better to fix…
