How to pass parameter into code-template in eclipse-plugin

Question

I want to create a plugin which defines a new code template (like this blog post). How can I pass a parameter into the template? like ${name:param}?

Answer 1

This solution is aimed at Eclipse 4.2 Juno, I have not tested this in any other environment.

All you have to do is pass your parameters, and then you'll have them available.

Say we wanted to create a TemplateVariableResolver that would uppercase the first letter of a passed parameter.

You'll first populate your plugin.xml as follows:

You'd also create your custom resolver:

public void resolve(TemplateVariable variable, TemplateContext context) {
    if (variable.getVariableType().getParams().size() > 0) {
        StringBuffer result = new StringBuffer();
        for(String value : (List) variable.getVariableType().getParams()) {
            value = value.substring(0,1).toUpperCase() + value.substring(1);
            result.append(value);
        }
        variable.setValue(result.toString());
    }
}

Finally in your code Template:

String name = ${Uppercase(jim,laughlin)};
