Neos Fusion Console debug helper for Neos 3.x

Debug.fusion

##
# This object will output fusion variables to the browser console.
#
# Example usage:
#
# @process.addDebugOutput = Shel.Helper:Debug {
#     output = ${node.identifier}
# }
#
# Which will prepend the current node oder document node label by default.
#
# To have a custom title do this:
#
# @process.addDebugOutput = Shel.Helper:Debug {
#     title = 'My node identifier'
#     output = ${node.identifier}
# }
#
prototype(Shel.Helper:Debug) < prototype(Neos.Fusion:Value) {
    value = ${value}
    title = ${node ? node.label : (documentNode ? documentNode.label : 'Untitled')}
    output = ''
    @process.addDebugOutput = ${value + '<script>console.log("' + this.title + ':",' + Json.stringify(this.output) + ');</script>'}
}
