Follow above instructions in order to get the content of your grails plugin from older grails into grails 3.

A few notes on plugin names and folder names, I put down a few things here: https://groups.google.com/forum/#!topic/grails-dev-discuss/cG_6mvAO3f8

In there I mentioed mvn install - which does not appear to work under normal circumstances, in order to get a plugin to work locally follow grails install instructions or do it as inline plugin ..

If you want to use a variable value as key of your map, then you should wrap your key with parenthesis. It makes key to be considered as expression instead of String literal.

String keyVar = "mykey"

def map0 = [keyVar : 12]
assert map0.keyVar == 12
assert !map0.mykey

Riot.js & MicroJS, a misplaced initiative

I was recently asked for my opinion about Riot.js and what I thought about the MicroJS movement, as part of my residency for the wonderful Hacker Retreat initiative. Here's my thoughts.

Looking at the source, Riot.js is only a jQuery based event emitter you can attach to instances called observable with a trivial router that aliases to pushState. Everything else, you create, including the the CRUD abilities.

As someone who've recently tried to go Micro.js. I've actually given up on this rebuild from the ground up style approach. There is no support, no documentation, and no community to help you accomplish big prime time applications. Once you hit a wall, or try do to something that isn't included in the trivial amount of code there is, you're on your own, with no help besides "figure it out! that's what micro.js is about!".
