Grab the unique OPC methods from an exported OPC Analyzer trace

GetUniqueOPCMethods.rb

#! ruby
#
# Gets the unique OPC methods from the OPC analyzer trace log of all the methods TopView Configurator and Engine uses

# Assumes that it has been given a valid file name
if ARGV.length == 1 and File.exists?(ARGV[0])
  input = File.open(ARGV.first, "r").read

  # Build up a unique array of OPC methods
  opc_methods = []

  # For each line in the file, pull out the package::method name string and put it in the opc_methods collection
  input.lines.each do |line|
    if match = line.match(/\w+\:\:\w+/).to_s and !opc_methods.include?(match)
      opc_methods << match
    end
  end

  # Chop out all the repeats and print the unique method names
  puts "Unique OPC method calls:"
  opc_methods.sort.each do |method_name|
    puts "#{method_name}\n"
  end

else
  puts "Please give me the name of a valid file!"
end

For this utility i expect that the exported trace file is given to this script as an argument. This will run off of *nix or Windows with ruby installed.
