JTT

Fast template engine for Java. This is a port of Perl5's popular template engine named Template-Toolkit 2.

Project status

In development.

But most of features are implemented.

API may change without notice.

Versioning

This project respects semantic versioning.

Architecture

• VM has TemplateLoader

ERD

We need ER Diagram.

Operators

  left	terms and list operators (leftward)
  left	.
  right	!
  left	* / %
  left	+ - _
  nonassoc	named unary operators
  nonassoc	< > <= >=
  nonassoc	== !=
  left	&&
  left	||
  nonassoc	..
  right	?:
  right	=
  left   AND
  left   OR

INCOMPATIBILITY WITH Templte-Toolkit

• We need casting operator.
• 3 < 3.14 does not works correctly.
• Because these values are not comparable.
  • java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Double
• [% FOR x IN [1..10] %] does not works.
• Because you don't need to wrap by brackets.
• I can't understand why TT2 needs brackets.
• In JTT, you need to write this code as [% FOR x IN 1..10 %].
• VMethod is not supported. Because Java objects have own built-in methods.

Caching

You can cache the compilation result.

JTT's parser/compiler is slow. If you are using JTT in the web application, I recommend to use caching feature.

You can use JCS for caching(I will provide jtt-jcs package after few months...(maybe)).

FAQ

Why JTT doesn't support MACRO?

You can do it with INCLUDE or JavaScript.

Is there an "Casting operator"?

How do I parse casting operator?
