Stupid less (1) trick

Do you get tired of reading a man page, or even
perldoc, for cryin' out loud, and having to deal with the
POSIX regex engine instead of something more powerful and Perl-like? I
know I do. Every time I type /^[[:space:]]+something,
instead of /^\s+something, it just makes me sick. Something
ought to be done about this nonsense.

Well, after saying something like this to myself for the umpty-jillionth
time, I decided to look into it.

Announcing Perl::Critic::Policy::ControlStructures::ProhibitForeachHandle

A couple days ago I uploaded a Perl-Critic policy to find and complain about things like foreach ( <FOO> ) {...}. The problem (or at least potential problem) with this is that it sucks the entire file into memory before performing the first iteration. Which may be what you wanted, but may not be too.

I plan to leave it at a development release for a couple weeks to allow time for comments and so on. You can find it at its CPAN Search page.

Announcing Perl::Critic::Policy::Variables::ProhibitUnusedVarsStricter

The subject Perl-Critic policy is an alternate implementation of the core policy Variables::ProhibitUnusedVariables. My implementation attempts to do a more thorough job of finding unused variables.

The details of the policy can be found at Perl-Critic-Policy-Variables-ProhibitUnusedVarsStricter. My purpose here is more to discuss why the policy exists in the form it does.

Astro::SpaceTrack upgrade

For some time now, the Space Track web site, which is the official source for satellite orbital elements, has been working on an upgrade to a REST interface. This interface is scheduled to go live on February 20.

My module Astro::SpaceTrack retrieves orbital data from the Space Track web site. To track this change, I intend shortly to release a new version of Astro::SpaceTrack which uses the REST interface by default. My understanding is that the old, screen-scraping interface will be available for an indefinite (but finite) time. For details, click on the post title for the extended version of the post.

The Case of the Unexpected Pax

It was late afternoon of a chill November in Paris. I was walking along the quai, lost in a brown study. Looking up, I saw my friend C. Auguste Dupin approaching me.

"Ah, bon soir, mon ami," said Dupin, "and what brings you beside the Seine on this crisp evening?"

"Something has been puzzling me," I replied, "and I thought the walk would give my thoughts an opportunity to put themselves in order."

"It is a day of puzzlements, no? Will you not share your puzzlement with me?"

"Well," I demurred, "it is a small thing -- probably something I did to m…
