WebMacro

WebMacro is an open-source template engine written in Java. It's designed to separate content from presentation in web applications, allowing web designers and developers to work independently. WebMacro parses template files that contain HTML, XML, or other markup languages, interspersed with directives that are replaced with dynamic content retrieved from Java objects or other data sources.

WebMacro aims to provide a simple and understandable syntax for template creation, making it accessible to designers with limited programming experience. It supports features such as variable substitution, conditional logic, looping, and macro definitions.

The project was initially developed and maintained by ObjectWeb (now OW2 Consortium). It has been used in a variety of web applications and content management systems. While actively used for a period, its adoption has decreased in recent years with the rise of other template engines and frameworks.
