grails taglib to create groovy templates inside a gsp

GroovyTemplateTagLib.groovy

package com.mtail.taglib

import groovy.text.markup.MarkupTemplateEngine

class GroovyTemplateTagLib {
    //static encodeAsForTags = [tagName: [taglib:'html'], otherTagName: [taglib:'none']]
    def markupEngine = new MarkupTemplateEngine()


    def gtrender = { attrs, body ->
        markupEngine.createTemplate(body()).make().writeTo(out)
    }
}

You can use the taglib in your gsps like so
<g:gtrender>
div(class: 'my-class') { a('some groovy template action') }
<g:gtrender>
