Examples of groovy.text.SimpleTemplateEngine$SimpleTemplate

groovy.text.SimpleTemplateEngine
Processes template source files substituting variables and expressions into placeholders in a template source text to produce the desired output.
The template engine uses JSP style <% %> script and <%= %> expression syntax or GString style expressions. The variable 'out' is bound to the writer that the template is being written to.
Frequently, the template source will be in a file but here is a simple example providing the template as a string:
```
 def binding = [ firstname : "Grace", lastname  : "Hopper", accepted  : true, title     : 'Groovy for COBOL programmers' ] def engine = new groovy.text.SimpleTemplateEngine() def text = '''\ Dear <%= firstname %> $lastname, We <% if (accepted) print 'are pleased' else print 'regret' %> \ to inform you that your paper entitled '$title' was ${ accepted ? 'accepted' : 'rejected' }. The conference committee. ''' def template = engine.createTemplate(text).make(binding) println template.toString() 
```
This example uses a mix of the JSP style and GString style placeholders but you can typically use just one style if you wish. Running this example will produce this output:
```
 Dear Grace Hopper, We are pleased to inform you that your paper entitled 'Groovy for COBOL programmers' was accepted. The conference committee. 
```
The template engine can also be used as the engine for {@link groovy.servlet.TemplateServlet} by placing thefollowing in your web.xml file (plus a corresponding servlet-mapping element):
```
 <servlet> <servlet-name>SimpleTemplate</servlet-name> <servlet-class>groovy.servlet.TemplateServlet</servlet-class> <init-param> <param-name>template.engine</param-name> <param-value>groovy.text.SimpleTemplateEngine</param-value> </init-param> </servlet> 
```
In this case, your template source file should be HTML with the appropriate embedded placeholders. @author sam @author Christian Stein @author Paul King @author Alex Tkachman
