Constructor Details

#initialize(version_array) ⇒ Version #initialize(version_string) ⇒ Version #initialize(version) ⇒ Version

Returns a new instance of Version.

Overloads:

  • #initialize(version_array) ⇒ Version

    Examples:

    Version.new([1, 2, 3, 'rc.1', 'build.1']) => #<Version: @major=1, @minor=2, @patch=3, @pre_release='rc.1', @build='build.1'>

    Parameters:

    • version_array (Array)
  • #initialize(version_string) ⇒ Version

    Examples:

    Version.new("1.2.3-rc.1+build.1") => #<Version: @major=1, @minor=2, @patch=3, @pre_release='rc.1', @build='build.1'>

    Parameters:

    • version_string (#to_s)
  • #initialize(version) ⇒ Version

    Examples:

    Version.new(Version.new("1.2.3-rc.1+build.1")) => #<Version: @major=1, @minor=2, @pre_release='rc.1', @build='build.1'>
