PHP to Ruby: file_get_contents and file_put_contents

PHP had useful functions for writing/reading files without opening handle.

http://pastebin.com/Pw04Vgs6
There is some code implementing this feature in Ruby.
It extends Ruby’s basic String object with handy ‘get’ and ‘put’ methods.
Example usages and analogues in PHP are provided.

Note: Reading file may not be as efficient as PHP’s file_get_contents because PHP tends to use memory mapping techniques (if supported by OS).
Consider reading short thread about Ruby File.read.

Code under the cut: (same as in pastebin)

# Code by Cemil Necefov (Jamil Najafov)
# Implementing basic file_get_contents [http, local file] and file_put_contents[local file: [write, append]]
# Extending String
class String
def get
case self.scan(/^[a-zA-Z]+(?=\:\/\/)/) # get wrapper name
when 'http'
return Net::HTTP.get_response(URI.parse(self)).body
else
return File.read(self)
end
end
def put (tx, mode='w')
File.open( self, mode ) { |file| file.write tx }
end
end


# Usage # PHP analogue
'localfile.txt'.put 'some text data' # file_put_contents('localfile.txt', 'some text data')
'localfile.txt'.put 'another bit', 'a' # file_put_contents('localfile.txt', 'another bit', FILE_APPEND)

print 'localfile.txt'.get # echo file_get_contents('localfile.txt')
print 'http://www.google.com'.get # echo file_get_contents('http://www.google.com')
