Return true if v1 and v2 are not nil, (auto converted) array positions are type compatible and compare as v1 >= v2.

# File lib/syncwrap/version_support.rb, line 45
def version_gte?( v1, v2 )
  v1 = version_string_to_a( v1 )
  v2 = version_string_to_a( v2 )
  c = v1 && v2 && ( v1 <=> v2 ) #-> nil for String/Integer mix
  c && c >= 0
end

version_lt?( v1, v2 ) click to toggle source

Return true if v1 and v2 are not nil, (auto converted) array positions are type compatible and compare v1 < v2.

# File lib/syncwrap/version_support.rb, line 54
def version_lt?( v1, v2 )
  v1 = version_string_to_a( v1 )
  v2 = version_string_to_a( v2 )

  c && c < 0
end

version_string_to_a( v ) click to toggle source

Convert version decimal String to Array of Integer or String values. The characters '.' and '-' are treated as delimiters. Any remaining non-digit in a segment results in a String being returned for that segment. Return v if not a String (incl nil).

def version_string_to_a( v )
  if v.is_a?( String )
    v.split(/[.\-]/).map do |p|
      if p =~ /^\d+$/
        p.to_i
      else
        p
