G'day stevieb,

That's an extraordinarily similar list to what I might have written. :-)

My coding style generally falls into two camps: what I write for myself, and what I write for $work. Over the years (close to 30 now for Perl) my style has changed: not in leaps and bounds, but just a slow progression of what I hope is general, incremental improvements.

Given the similarity, I'll just go through your list and indicate what I do differently. Basically, if it's not mentioned, I do the same as you.

• I don't add that extra white space when deferencing. Something of a moot point for personally coding: I'm more likely to write "keys $href->{thing}->%*" (not a lot of oppotunity for whitespace there).
• I disagree that '->' is needed in '$hash{one}->{two}'. Of course, I can't see the underlying code but '$hash{one}{two}' would surely suffice.
• I do have some standard tests which I get through module-starter (some are just ones I added to the template directory and install manually from there). I'm not a huge fan of TDD. I do write tests during development; usually after I've added a handful of related methods, but never before.
• I don't use IDEs. I use vim for pretty much everything: possibly giving away my age when I think back to when vim was vi and my "monitor" was a roll of paper on the back of a teletypewriter console.
• I don't use the debugger either. I prefer Data::Dump over Data::Dumper in most cases.
• I don't use PPI; although, I am aware of it.
• GitLab CI/CD for $work only.
• Reading params with shift was something I did a lot, but not anymore. Too many instances of needing a extra param and changing "my $x = shift;" to "my ($x, $y) = shift;" — and that can be a surprisingly difficult bug to track down. Anyway, I've used "@_" pretty much exclusively since the early 2000s.
• I would have written hundreds of modules using "pure perl OOP"; mostly for $work but also for personal code. I was very pleased when modules started to appear to shoulder some of the work. I used quite a few but mainly use Moose, and occasionally Moo, these days. I'm keeping my eye on Cor.

++ for a good post. It'll be interesting to see what others come up with.
