Templates for Java

Welcome to my humble Java templates page. It is a general text based templating system. It is very easy to use and very powerful. It can be used for almost anything - starting from code generation at translators/compilers to HTML outputing at Java servlets.

Latest release: jtlt-0.4.tar.gz at 13-10-2003.

Features

  • Replaceable keys
  • Block structure, blocks can be nested
  • Extensible macro system (actually even keys are implemented as macros)
  • Separation of parsing and output generation
  • Separation of macro settings and parsing
  • Due to last two points we'll get in memory caching of parsed templates
  • Designed to be fast
  • Syntax of macro directives can be redefined
  • Macros can have macros generate their arguments
  • Macros can be recursive, eg. macro output can be post-parsed for macro tags
  • Html template specialization
  • Localization database support for the html template, aliases
  • Weak typing, no exceptions on every little thing
  • Well documented API

Download

The code is downloadable here: jtlt-0.4.tar.gz. It already contains all the documentation and a jar file so you don't have to do much work to get it running. Code is distributed under the GNU "lesser" public license (GNU LGPL).
