Adapts Grails taglibs for use in the template engine. An adapter may be created like this:
def model = [:]
def tpl = template.make(model)
model.g = new TagLibAdapter(tpl)
model.g.registerTagLib(SimpleTagLib)
where SimpleTagLib is:
class SimpleTagLib {
def emoticon = { attrs, body ->
out << body() << (attrs.happy == 'true' ? " :-)" : " :-(")
}
}
Then it can be used inside a template like this:
g.emoticon(happy:'true') { 'Hi John' }
Performance-wise, it would be better to reimplement the taglib, but this makes it easier to reuse
exisiting code.
