Implementing Text Editors

9th July 2003

Via Martin Spernau, two useful resources on writing text editors. The Craft of Text Editing appears to be the definitive work on the subject, and is a whole book made available online with permission from the publishers as it is no longer available in print. Writing a Simple Word Processor (PDF) is a more recent paper with excellent overviews of the data structures and algorithms used in modern editing widgets.
