SemVer

SemVer is a very simple semantic version parser in Ruby. It takes a string and returns an object that can be validated and compared.

Examples

require 'sem_ver'

SemVer.parse('0.0.10').valid?                       # true
SemVer.parse('v1.0.10').valid?                      # true
SemVer.parse('X.10').valid?                         # false

SemVer.parse('1.0.0') >  SemVer.parse('0.9.9')      # true
SemVer.parse('1.0.1') >= SemVer.parse('1.0.0')      # true
SemVer.parse('1.0.1') >= SemVer.parse('1.1.0')      # false
SemVer.parse('1.0.0') == SemVer.parse('1.0.0-pre1') # false
SemVer.parse('1.0.0') >  SemVer.parse('1.0.0-pre1') # true

...
