jcamenisch / currency.rb
Last active December 18, 2015 22:39
A simple currency class
class Currency
def initialize(value)
@value = (value || 0).to_d.round(2)
end
attr_reader :value
alias_method :to_d, :value
def to_currency; self; end

jcamenisch / unmaybe.rb
Created June 25, 2013 04:00
Return blackhole object with maybe(something), but convert blackhole back to nil with a chain-closing method. Because sometimes we need to send values to outside code that understands the nil idiom, but not our "exotic" blackhole object.
class BlackHole
def method_missing(*args, &block)
self
end
def unmaybe
nil
end

jcamenisch / continueFormulas.js
Created August 21, 2013 02:14
To be triggered on form post in a Google Spreadsheet. This simple function will copy calculations from an early row to the rest of the rows (including the blank row that was newly inserted by the form post).
// How I had it as of this morning, 8/20/2013
var _inputSheet;
function inputSheet() {
return _inputSheet || (
_inputSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Input')
);
}

Last active December 21, 2015 10:09
Given a list of people on a rotation to cover some responsibility, send notifications to the next people who's shift is approaching. To test this, 1. Make a duplicate of https://docs.google.com/spreadsheet/ccc?key=0AsonuW5GGQ5sdGtaTEFBZ1pzYTZ2ZzFZTWZvbW1nbmc for your sandbox. 2. In the menu of your spreadsheet, navigate to Tools > Script Editor.…
/*

var sheetDefaults = {

jcamenisch / list_method_arguments.rb
Last active August 29, 2015 14:02
List arguments to a Ruby method
def get_inputs(a, b, c)
Hash[local_variables.map { |name| [name, binding.local_variable_get(name)] }]
end
get_inputs('one', 'two', 'three')
#=> {:a=>"one", :b=>"two", :c=>"three"}
# Or package that in a reuseable method like so:
def get_local_variables(a_binding)
