#new(vr, e = nil) ⇒ Version #new(v, r, e = nil) ⇒ Version

Examples:

RPM:: Version.new "1.0.0-3"
RPM:: Version.new "1.04"
RPM:: Version.new "1.0.0-3k", 1
RPM:: Version.new "2.0.3", "5k"

Overloads:

  • #new(vr, e = nil) ⇒ Version

    Creates a version object from a string representation

    Parameters:

    • vr (String) —

      version and release in the form “v-r”

    • e (Number) (defaults to: nil) —

      epoch

  • #new(v, r, e = nil) ⇒ Version

    Creates a version object from a string representation

    Parameters:

    • v (String) —

      version

    • r (String) —

      release

    • e (Number) (defaults to: nil) —

      epoch

#<=>(other) ⇒ Number

Comparison between versions

Examples:

v1 = RPM::Version.new("3.0-0",1)
v2 = RPM::Version.new("3.1-0",1)
v1 <=> v2
=> -1

Parameters:

Returns:

  • (Number) —

    -1 if other is greater than, 0 if other is equal to, and +1 if other is less than version.
