views: {
gender: {
map: function(doc){

Sample CouchDB map functions for working with dates without a library.
function(doc){
// handle a custom format using methods in the date object
var format = "{getFullYear}/{getMonth}/{getDate}",
date = new Date(doc.created_at),
// use a regular expression to replace parts of our format string
formatted_date = format.replace(/\{(\w+)\}/g, function(str, func){
var time = date[func]();
// if `func` is `getMonth` we must offset by one
if(func === 'getMonth'){
time += 1;

Using `jq` to pipe couchdb contents into `dat`
# _all_docs
curl http://localhost:5984/eggchair/_all_docs?include_docs=true | jq -c ".rows[] | .doc" | dat --json

Solution to every level of RubyWarrior (https://www.bloc.io/ruby-warrior/#/). Heavily borrowed from https://gist.github.com/jnf/6198927
# N.B. doesn't get maximum score:
# * won't get captives behind the warrior
# * will shoot captives at look[1] if an enemy is in look[2]

# @max_health ||= warrior.health # set to `1` to complete level 8 in 27 turns
