GitHub's compare view is available at:

https://github.com/$USER/$REPO/compare/$REV_A...$REV_B

Naturally, $USER and $REPO are the owner (user/organization) and repository names, respectively.

$REV{A,B} are the two sides of the compare view; they can either be a ref in $USER's repository, i.e. the name of a branch, tag or a commit SHA, or it can be a ref in $OWNER's fork of the repository by using the format $OWNER:$REF.

You can get a diff or patch for the result of the compare view by appending .diff or .patch to the URL, respectively.

One of CoffeeScript's best features is the @ shorthand for this -- perfect for accessing instance methods and properties:

class Rectangle
  constructor: (@width, @height) ->
  getArea: ->
    @width * @height

But there's no similar shorthand for accessing static members, e.g. @@. So instead, you're forced to either hardcode class names, or type out the long constructor reference to be generic:

Examples

stopBefore(document, 'getElementById')
stopBefore('document.getElementById') // the same as the previous
stopBefore(Element.prototype, 'removeChild')
