Method Calls[edit] The Unofficial Ruby Usage Guide You may be interested to know that this document was originally written for internal use in the Operations department at Google. At the time, I was campaigning for the right to use Ruby on internal projects and I felt that a style and usage guide would probably assist in the battle for the language's acceptance, as the officially sanctioned languages at the time already had one. If nothing else, we'd at least all end up writing code that was easier to maintain. Over the last few years, Ruby has struck a chord with programmers as an excellent tool for -- amongst other things -- system administration. With that as our perspective, this document will suggest some guidelines for writing Ruby code in such a way that a common stylistic vocabulary may emerge, thereby increasing the ease with which source code may be read and shared. If you have questions about this document, please address them to its author, Ian Macdonald.
