Specify the min perl version for your distribution

It's a good idea to specify the minimum Perl version required by your distribution. It's useful information for people looking at your code, it's helpful for CPAN Testers (which will report NA for old perls, rather than failing), and it makes the requirement clear to people who are trying to install your module on an older Perl.

Splitting a Catalyst App and recombining it with Plack::Builder

I had a big Catalyst App serving HTML.

Some time later a RESTful interface was needed so I added RESTful controllers using Catalyst::Controller::REST

But that broke Plack::Middleware::CSRFBlock, because the REST calls don't request a form and thus cannot add the secure token to POST requests.

Thinking about a solution it dawned on my that having a single App serving HTML and RESTful requests is probably a bad design choice.

Thankfully most of my business logic is in my DBIx::Class schema so splitting up one Catalyst App into two Catalyst Apps under the same namespace shouldn't be much of a problem.

Let's call the old App 'MyApp'. I wanted the new Apps to be named 'MyApp::Web::HTML' and 'MyApp::Web::API'

First part was to create lib/MyApp/Web/API and lib/MyApp/Web/HTML folders and moving as much components (Controllers/Views/Forms) there as possible. This part meant quite some renaming of file and package names. Your IDE can be quite helpful with that.

Quickly Check for Database Design Flaws

Don't you just hate it? You've finished reading, again, that blog entry about database design and you're feeling that you can design something reasonable, and then you see this table:

EmployeeID| SalesPerson| SalesOffice| OfficeNumber| Customer1| Customer2| Customer3
1003 Mary Smith Chicago 312-555-1212 Ford GM
1004 John Hunt New York 212-555-1212 Dell HP Apple
1005 Martin Hap Chicago 312-555-1212 Boeing

You can easily see that Customer1, Customer2, and Customer3 are wrong, but what about the rest? Try as you might, you can't quite put all of the rules together that easily to figure out what's wrong with the above table.

There's a shortcut, though, and it makes it very easy to start understanding database design.

Put your CPAN distributions on github

If your CPAN distributions aren't already on github, then I think you should consider adding them. Github is the most popular code hosting service, so it's the first place many people will look for your code.

If your distributions are on github, it makes it a lot easier for people to submit changes (like bug fixes) via pull requests. And if it's easier, it's more likely that people will.

If you do add your dists to github, then you should make sure that you give the repo in the dist's metadata and the documentation too.

MadMongers Tonight

Come hang out with us at Essen Haus tonight and participate in a series of mini-talks about where Perl can go. You might be surprised.

Classify your RT tickets on CPAN Day!

Last week I encouraged y'all to fix a bug or two on CPAN Day, either in your distributions, or in someone else's. To help you, I listed the top 20 dists by bugs.

David "never satisfied" Golden pointed out that the table would be more useful / interesting if broken down by severity. So here it is. This also reveals that a lot of tickets don't have a severity set, so on CPAN Day we should sort that out too!

Creating an MMORPG in Perl

Question: do you want to hear more about my attempts to create an MMORPG in Perl, even if posts are not Perl-related? Also, are you interested in helping me develop its ideas further?

As many of you know, I'm trying to create an MMORPG running on Perl. It's codenamed veure. Though I've written about it a few times here, I've not written much because many of the entries are about game design and not strictly about Perl. As a result, I've tried to avoid spamming this blog. That being said, people constantly say "stop talking about how great Perl is and build great things with it!" So I'm trying to build something great with Perl, but as most experienced programmers know, it's not so much the programming language as the business rules which are important.

And damn, business rules in an MMORPG are hard.
