Reading and Writing Java Property Files With Ruby

Created a simple Class in ruby to help reading and writing property files

class JavaProps
attr :file, :properties

#Takes a file and loads the properties in that file
def initialize file
@file = file
@properties = {}
IO.foreach(file) do |line|
@properties[$1.strip] = $2 if line =~ /([^=]*)=(.*)\/\/(.*)/ || line =~ /([^=]*)=(.*)/
end
end

#Helpfull to string
def to_s
output = “File Name #{@file} \n”
@properties.each {|key,value| output += ” #{key}= #{value} \n” }
output
end

#Write a property
def write_property (key,value)
@properties[key] = value
end

#Save the properties back to file
def save
file = File.new(@file,”w+”)
@properties.each {|key,value| file.puts “#{key}=#{value}\n” }
end

end
