The '''WASTE''' (an acronym for '''WorldScript-aware styled text engine''') is an [[Apple Macintosh]] text editing [[software]] [[Library (computer science)|library]]. WASTE helps Macintosh programmers include advanced text display and editing in their applications.

WASTE is a memory-based editor, which places [[zero one infinity rule|no arbitrary limit]] on the amount of text being edited, up to available system memory. It supports the Macintosh [[WorldScript]] system, allowing it to handle [[DBCS|double-byte character sets]] and [[bi-directional text]]. It includes automatic support for undo operations, [[drag and drop]] editing, [[Justification (typesetting)|text justification]], embedding images into text, and low-level hooks for rendering and measuring text.

WASTE version 2.0 gained support for paragraph-level formatting, additional character styles, multiple undo and redo operations, [[Unicode]] translation, and [[Mac OS X]] [[Carbon (computing)|Carbon]] support, as well as providing new [[application programming interface]]s (APIs) for printing and string matching.

WASTE is a popular third party library used in many Macintosh applications, formerly under the [[Classic Mac OS]] and more recently under Mac OS&nbsp;X, including [[Netscape Navigator]], [[Internet Explorer for Mac|Internet Explorer]], [[Microsoft Entourage]], [[Microsoft Office 2011|Microsoft Outlook for Mac]], [[REALbasic]], and [[Tex-Edit Plus]].

Since WASTE uses deprecated [[QuickDraw]] features, it was deprecated in Mac OS&nbsp;X version&nbsp;10.4<ref name="Quartz Programming Legacy">{{cite book
