DSLEdit

A Domain Specific Language or DSL is a custom programming language designed exclusively for use with a specific task. DSLs are commonly used in Ruby, where Ruby’s flexible syntax allows you to build and embed DSLs within the Ruby source. For example, in Walrus I use a DSL for the purposes of defining grammars.
