| Agile Asset Management with Ruby DSLs |
|
A domain specific language is a language-oriented tool designed to solve a specific set of programming tasks. Common traits are very close to the problem domain within which the language is intended to work, and operating at a very high level of abstraction. In his article about DSLs, Martin Fowler classifies DSLs as either external or internal (see link). An external DSL is a programming language that is either compiledor interpreted. An internal DSL is built within a general-purpose programming language. Effectively, an internal DSL is a very high-level API to a general-purpose programming language. This article is a story about how implementing an internal DSL for Ruby contributed to a PLANET ARGON development project. |
