Common Lisp Cheatsheet

Common Lisp is a general-purpose programming language with functions as first-class citizens. Don't worry about being purely functional, Lisp is Object Oriented too. CLOS is a very powerful object-oriented system!

Useful definitions

The Common Lisp lingo is quite unique:

• Package: Basically a namespace, a place for symbols to live
• System: Basically a Library. A bunch of code plus some instructions how it should be treated, for example which other systems it depends on, what should be loaded and/or compiled first, etc. Not in ANSI lisp but widespread. The most common system definition tool is ASDF.
• Modules: Deprecated and implementation-dependent
• Quicklisp: Like NPM or Ruby Gems for ASDF Systems.

App.Lib.GlobalEvents =

  This will trigger the callback whenever the user clicks on something outside
  the given element. If the user clicks on something insied `el`, it will not
  trigger the callback.
  You can give it many elements using jQuery's `#add`:
      $els = $('.my-element').add($('.some-other-element'))
      App.Lib.GlobalEvents.onClickedOutside $els, =>
        # do something

Caching

This can cache AJAX requests across page-loads with custom max-ages:

FIVE_MINUTES = 5 * 60 * 1000
App.Lib.Cache.promise().maxAge(FIVE_MINUTES).cache('/foo', -> $.get('/foo')).then (results) ->
  console.log results
