= Ruby Packaging Standard | |
The aim of this document is two-fold. First, to specify a common | |
structure of how a Ruby package distributed as source (that is, but | |
not limited to, development directories, version-controlled | |
repositories, .tar.gz, Gems, ...) should conform to. | |
Second, to document common and proven ways to structure Ruby packages, | |
and to point out certain anti-patterns that sneaked into common use. | |
It is by intent not to innovate. |
I’m working on both learning authlogic and Rails 3. The process here works (given the Rails 3.0.0.beta1 gem) for me. There is a list of the many resources I complied this from at the bottom of the document.
Travelers beware: this is incomplete, and possibly even wrong. But between the stuff about scaffolding and binary logic’s example app you should be able to get off your feet.
We assume Rails 3 is installed. We will create a rails app as usual.
rails authtest cd authest rails g scaffold post title:string body:text rails g scaffold user username:string fullname:string is_admin:boolean
“A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.”
