Refactoring With Delphi 2005

The concept of refactoring is not new; its origins can be traced back as far as 1992 at least. Refactoring is something that we have all been practicing for many years, without actually knowing it. Indeed, like gravity (which existed prior to it being named), each and every one of us have been spending time improving the design of existing code, re-testing it, incrementing the version number and shipping new versions to customers. Between 1992 and 1995 the word refactoring entered common usage; in 1999, Martin Fowler pushed refactoring into the mainstream with the publication of his Refactoring book.

Martin Fowler’s seminal works [1] and his web-site [2] provide us with a collection of small changes that we can apply to our code, small changes that drive towards improving the design and making the code easier to read, more maintainable thus extending its life. Fowler is correct in stating that his book and his web-site are not definitive collections of refactorings as it is very likely that you will discover “new” ways of improving the design of your existing code.
