Helpful CoffeeScript console debugging function

debug_log.coffee

d = (s) -> o = {}; o[k] = eval(k) for k in s.split(' '); console.log JSON.stringify(o, null, '  ')

# Or, the compiled JavaScript:

d = function(s) {
    var k, o, _i, _len, _ref;
    o = {};
    _ref = s.split(' ');
    for (_i = 0, _len = _ref.length; _i < _len; _i++) {
      k = _ref[_i];
      o[k] = eval(k);
    }
    return console.log(JSON.stringify(o, null, '  '));
  };

# Stop writing things like:
#   console.log "some_var: #{some_var} - some_other_var: #{some_other_var}"
# Instead, just pass in a string of the vars you're interested in,
# and get back the results in an easy to read format.
#
# Usage: d 'some_var some_other_var'
# IN:  A string of var names.
# OUT: A log entry in your console of an object 
#      where the keys are the var names and the values are the vars' values.
#
# For example...
#
# If we have these vars:
# num = 1
# str = 'some string'
# obj = {name: 'Gabe', age: 31, foods: ['Sushi', 'Pizza']}
# 
# And we call: d 'num str obj'
#
# The console log writes: 
#{
#  "num": 1,
#  "str": "some string",
#  "obj": {
#    "name": "Gabe",
#    "age": 31,
#    "foods": [
#      "Sushi",
#      "Pizza"
#    ]
#  }
#}
