The Magic Variable 'count'
So, I happened to be looking back through some old files and I found an early programming assignment from my first computer science course back in college. In the middle of the code I found this wonderful line:
while (cownt<years) {
cout<<cownt+1; //"cownt" = "count", but when I entered it spelt correctly it gave me errors.//
As it turns out early on in the code I declared int cownt=0;. I either couldn’t find this typo in debugging my mere 61 lines of code or — what I think was actually going on — I thought count was a reserved magical variable that made loops work — not something I had to declare. Sometimes it’s nice to look back and see how far you’ve come.
Perfect Perl Kwalitee
In the time since Date::Lectionary was added to CPAN, I’ve been working hard to get a perfect Kwalitee score and make a really solid distribution. Documentation on how to make a module are all over the place and I’ve yet to see a good, single article or post to explain how to do it. This is my attempt, I hope you find it useful.
Required Files
README
I like keeping my POD within the code of the module I’m developing and having the README file(s) automatically generated from that. Below is a simple shell script I’ve developed as part of my authoring process to generate well-formed readme files in Markdown, POD, and plaintext. Having all three formats means that GitHub and MetaCPAN both have what they need to render my README as best as possible.
