Debuggable Template Engine

This library provides implementation of Groovy TemplateEngine with better error reporting which maps the parse exception to the original template.

The template engine is fork or original SimpleTemplateEngine.

Example

For following template with missing brackets after if (true) statment:

Hello world!
<% if (true) %>
This will fail due missing opening bracket!
<% } %>

You get following error message:

unexpected token: ;

1   : Hello world!
2   : <% if (true) %>
=   :                ^
3   : This will fail due missing opening bracket!
4   : <% } %>

The template was parsed into following script:

1   : out.print("""Hello world!
2   : """); if (true) ;
=   :                 ^
3   : out.print("""
4   : This will fail due missing opening bracket!
5   : """); } ;
6   : out.print("""""");
