oose(3)

✨ oose ✨

okay bestie, so this is oose(3) from the User Contributed Perl Documentation, and it's literally the cutest little thing — syntactic sugar to make Moose one-liners easier 🍓

---

💖 VERSION 💖

version 2.4000 — she's giving established, she's giving stable, periodt 👑

---

🌸 SYNOPSIS 🌸

# create a Moose class on the fly ...
perl -Moose=Foo -e 'has bar => ( is=>q[ro], default => q[baz] ); print Foo->new->bar' # prints baz

# loads an existing class (Moose or non-Moose)
# and re-"opens" the package definition to make
# debugging/introspection easier
perl -Moose=+My::Class -e 'print join ", " => __PACKAGE__->meta->get_method_list'

# also loads Moose::Util::TypeConstraints to allow subtypes etc
perl -Moose=Person -e'subtype q[ValidAge] => as q[Int] => where { $_ > 0 && $_ < 78 }; has => age ( isa => q[ValidAge], is => q[ro]); Person->new(age => 90)'

like, that last one is so unhinged and I'm obsessed with it 💅

🦋 DESCRIPTION 🦋

oose.pm is a simple source filter, no cap. What it does is it adds this lil' incantation to the beginning of your script:

package $name; use Moose; use Moose::Util::TypeConstraints;

and the whole reason it exists? Because typing perl -e'package Foo; use Moose; ...' was annoying the author. That's it. That's the origin story. main character energy fr fr 😭✨

---

🎀 INTERFACE 🎀

oose provides exactly one method, and perl calls it automatically for you — she doesn't need an invitation, she just shows up 🌈

• import($package) — Pass a package name to import and it'll be used by the source filter. If you don't give one, the package defaults to Class. generous queen 🫶

---

🧚 DEPENDENCIES 🧚

You will need Filter::Simple, and eventually Moose 💜

---

💀 INCOMPATIBILITIES 💀

None reported. But listen — it is a source filter, so like… it might have issues there. Not me being dramatic, that's just the vibe of source filters 🙈
