Getting started new to ruby Start with our getting started guide Core classes and modules explore the essential classes and modules Returns the ruby objects created by parsing the given source This method is meant to serialise data from trusted user input, like from your own database server or clients under your control, it could be dangerous to allow untrusted users to pass json sources into it. Identical regexp can or cannot run in linear time depending on your ruby binary
Neither forward nor backward compatibility is guaranteed about the return value of this method. The ruby processing system rdoc, for example, has one that can be used elsewhere Other popular template processors may found in the template engines page of the ruby toolbox. Does ruby have class methods A singleton method of a class object is called a class method (actually, the class method is defined in the metaclass, but that is pretty much transparent)

When one operand is a regular expression and the other is a string then the regular expression is used as a pattern to match against the string. Chmod ('u=wrx,go=rx', '/usr/bin/ruby') keyword arguments Chmod (0644, ['src0.txt', 'src0.dat'], noop Ruby is developed under linux, and is written in fairly straightforward c Ruby’s grammar differentiates between statements and expressions
