Dpkg::Deps::KnownFacts(3perl)

💖 NAME 💖

okay bestie, welcome to Dpkg::Deps::KnownFacts — this is the Dpkg::Deps::KnownFacts(3perl) page from libdpkg-perl, and it's literally a list of installed real and virtual packages. 👑

---

✨ DESCRIPTION ✨

This class represents a list of installed packages and a list of virtual packages provided (by the set of installed packages).

Think of it as the group chat roster: one list for the installed packages, and another for the virtual packages that the installed set provides. It's giving dependency-tracking main character energy. 💅

🛠️ METHODS 🛠️

• $facts = Dpkg::Deps::KnownFacts->new(); — creates a new object. Fresh object, no cap. ✨
• $facts->add_installed_package($package, $version, $arch, $multiarch) — records that the given version of the package is installed. If $version/$arch is undefined, we know that the package is installed but we don't know which version/architecture it is. $multiarch is the Multi-Arch field of the package. If $multiarch is undef, it will be equivalent to Multi-Arch: no. Note that $multiarch is only used if $arch is provided. 🫶
• $facts->add_provided_package($virtual, $relation, $version, $by) — records that the $by package provides the $virtual package. $relation and $version correspond to the associated relation given in the Provides field (if present). 💖
• $facts->evaluate_simple_dep() — this method is private and should not be used except from within Dpkg::Deps. Like, do not touch it unless you're literally inside Dpkg::Deps, bestie. 🫣
