| 1 Templates in Groovy |
| |
| The template framework in Groovy consists of a TemplateEngine abstract base class that engines must |
| implement and a Template interface that the resulting templates they generate must implement. |
| |
| Included with |
| Groovy is the SimpleTemplateEngine that allows you to use JSP-like scriptlets, script, and EL expressions in |
| your template in order to generate parametrized text. Here is an example of using the system: |
| |
| {code:groovysh} |
| import groovy.text.Template |
| import groovy.text.SimpleTemplateEngine |
| |
| text = 'Dear \"${firstname} ${lastname}\",\nSo nice to meet you in <% print city %>.\nSee you in ${month},\n${signed}' |
| |
| binding = ["firstname":"Sam", "lastname":"Pullara", "city":"San Francisco", "month":"December", "signed":"Groovy-Dev"] |
| |
| engine = new SimpleTemplateEngine() |
| template = engine.createTemplate(text) |
| template.setBinding(binding) |
| |
| result = 'Dear "Sam Pullara",\nSo nice to meet you in San Francisco.\nSee you in December,\nGroovy-Dev' |
| |
| assert result == template.toString() |
| {code} |
| |
| Though its possible to plug in any kind of template engine dialect, we can share the same API to invoke templates. |
| e.g. we could create a Velocity / FreeMarker flavour TemplateEngine implemenation which could reuse GPath and auto-recompile to bytecode. |
