SimpleTemplate is a simple template engine written in Java. You can generate formatted text from a Java bean. You can use it for generating XML files, Web sites, etc. It features simple template directives, user-selectable template directive separators, alias creation using with and set directives, support for indexing into arrays, collections, and maps, looping on an array or a collection, a simple include mechanism to reuse template files, conditional evaluation using if and ifelse, and custom list separation settings (prefix, suffix, and separators). Template files can be read from the filesystem, class path, or just a string. Support for methods, aka. sub templates.
Rythm Template Engine is a general-purpose, high-performance Java template engine which uses a Razor-like syntax. It is 2-to-3 times faster than Velocity. It supports variables, expression evaluation, control flow (if-else-if), looping, template inheritance(decoration/layout), and many features. There is a Play!Framework plugin based on Rythm. You can use Rythm in any place to generate any type of text file, including HTML, XML, Json, SQL, and any kind of source code.
terp is a modular template engine that integrates tightly into ANT and provides a portable C++ compiler task (aCC, g++, icc, msvc++, SUN CC, xlC) on many platforms and processor architectures, a collection iterator task, a full-featured expression language with host introspection, formatters, selectors, and transformers for expressions, and much more. It can be embedded into Ant, used as a stand-alone or embedded templating engine, or used as a batch or interactive expression evaluator. It is extremely flexible and can be extended with your own types, operators can be overloaded, and properties and methods can be added to types.
