1 Incremental Development We’ll be developing this application incrementally. We won’t attempt to specify everything before we start coding. Instead, we’ll work out enough of a specification to let us start and then immediately create some functionality. We’ll try ideas out, gather feedback, and continue on with another cycle of minidesign and development. This style of coding isn’t always applicable. It requires close cooperation with the application’s users, because we want to gather feedback as we go along.

With other, less expressive languages, programmers rely on IDEs to do much of the grunt work for them: IDEs do code generation, assist with navigation, and compile incrementally to give early warning of errors. With Ruby, however, much of this support just isn’t necessary. Editors such as TextMate give you 90% of what you’d get from an IDE but are far lighter weight. ∗ I prefer using one editor for everything. Others use specialized editors for creating application code versus (say) HTML layouts.

We’ll see how to create simple maintenance pages, link database tables, handle sessions, and create forms. Over the next eight chapters, we’ll also touch on peripheral topics such as unit testing, security, and page layout. 1 Incremental Development We’ll be developing this application incrementally.
