Bio::R...ersion(3pm)

💖 Bio::R...ersion(3pm) — bestie, pls don't use this 💖

okay so this is the manual page for Bio::R...ersion(3pm) (yes the title's all truncated, that's just how the header rolls, don't @ me). It's part of the User Contributed Perl Documentation, and it's one of those pages where the name literally tells you the whole vibe: don't use it, grab the version from each module instead. 🫶

✨ NAME ✨

Bio::Root::Version — don't use, get version from each module

like. that's it. that's the name. it's giving "please stop touching me" energy and honestly? valid. 💅

---

🌸 SYNOPSIS 🌸

here's how the whole thing looks in the wild, no cap:

package Bio::Tools::NiftyFeature;
require Bio::Root::RootI;

# later, in client code:
package main;
use Bio::Tools::NiftyFeature 3.14;

## alternative usage: NiftyFeature defines own $VERSION:
package Bio::Tools::NiftyFeature;
my $VERSION = 9.8;

# later in client code:
package main;

# ensure we're using an up-to-date BioPerl distribution
use Bio::Perl 3.14;

# NiftyFeature has its own versioning scheme:
use Bio::Tools::NiftyFeature 9.8;

okay so notice how there's two whole strategies happening in there and they coexist, that's the point, that's the moment. ⭐

🦋 DESCRIPTION 🦋

so this module exists to give all the other BioPerl modules a mechanism where they can all share the same $VERSION — and the whole reason is so nobody has to go manually synchronize every single file by hand like some kind of Victorian orphan. it's iconic, honestly. the way that it just… handles it for you. 🎀

and here's the tea: Bio::Root::RootI itself uses this module. so any module that directly (or indirectly) uses Bio::Root::RootI will get a global $VERSION variable set — but only if it's not already set. like it's polite about it. it doesn't overwrite your vibe. 🙈

lowkey important: "if it's not already" is doing a LOT of work in that sentence, so if you've defined your own $VERSION you're safe, bestie. 👑

and that's the whole page, babes ✨ it's a short one but it ate.

cute little sign-off: this doc rode in on perl v5.32.1, dated 2021-08-15, and it's filed under Bio::R...ersion(3pm) like we said at the top. mwah 💋
