Default values for the Rulers are based on a number of style guides in the Ruby community as well as what seems to be common. More on this here http://wiki.github.com/turboladen/tailor. tailor's goal is to help you be consistent with your code, throughout your project, whatever style that may be.

outlaw

Keep bad code out of your projects. Your idea of bad code, no one elses. Outlaw defines an example based DSL for demonstrating anti-patterns and builds a rule for each anti-pattern that it alerts the user to violations when encountered in a project's codebase during scanning. Outlaw is a work in progress and contributions, suggestions and forks are welcome. Outlaw was a personal project for Mendicant University, Session 10 in Jan '12
