📖 NAME

Dpkg::Deps::OR - list of OR dependencies

🚀 Quick Reference

Use Case	Command	Description
Output dependency string	$dep->output([$fh])	Output sub-dependencies joined by " | "
Check implication	$dep->implies($other_dep)	Check if this dependency implies another (returns 1, 0, or undef)
Evaluate truth	$dep->get_evaluation($facts)	Evaluate dependency truth given known facts
Simplify dependencies	$dep->simplify_deps($facts, @assumed_deps)	Simplify dependency based on known facts and assumed deps

📝 DESCRIPTION

This class represents a list of dependencies of which only one must be met for the dependency to be true. It inherits from Dpkg::Deps::Multiple.

🛠️ METHODS

• $dep->output([$fh]) - The output method uses " | " to join the list of sub-dependencies.
• $dep->implies($other_dep) - Returns 1 when $dep implies $other_dep. Returns 0 when $dep implies NOT($other_dep). Returns undef when there's no implication. $dep and $other_dep do not need to be of the same type.
• $dep->get_evaluation($facts) - Evaluates the dependency given a list of installed packages and a list of virtual packages provided. These lists are part of the Dpkg::Deps::KnownFacts object given as parameters. Returns 1 when it's true, 0 when it's false, undef when some information is lacking to conclude.
• $dep->simplify_deps($facts, @assumed_deps) - Simplifies the dependency as much as possible given the list of facts (see object Dpkg::Deps::KnownFacts) and a list of other dependencies that are known to be true.
