Templates prefix and suffix

A TemplateLoader provides two important properties:

• prefix: useful for setting a default prefix where templates are stored.
• suffix: useful for setting a default suffix or file extension for your templates. Default is: '.hbs'

Usage:

 TemplateLoader loader = new ClassPathTemplateLoader();
 loader.setPrefix("/templates");
 loader.setSuffix(".html");
 Handlebars handlebars = new Handlebars(loader);

 Template template = handlebars.compile("mytemplate");

 System.out.println(template.apply("Handlebars.java"));
 

The template loader resolve mytemplate to /templates/mytemplate.html and load it.
