Module: Philiprehberger::Semver::Range

Defined in:
lib/philiprehberger/semver/range.rb

Overview

Evaluates version constraint strings against a Version.

Supports comma-separated constraints using the operators >=, <=, >, <, =, ~> (pessimistic) and ^ (compatible). A bare version string (no operator) is treated as exact match.

Class Method Details

.satisfies?(version, constraint) ⇒ Boolean

Check whether version satisfies every comma-separated constraint.

Parameters:

  • version (String, Version) —

    the version to test

  • constraint (String) —

    one or more comma-separated constraints

Returns:

  • (Boolean) —

    true if every part of constraint is satisfied
