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.

; This is a very basic intro to Seesaw, a Clojure UI toolkit. It covers
; Seesaw's basic features and philosophy, but only scratches the surface

Switch To Vim For Good

NOTE: This guide has moved to https://github.com/bpierre/switch-to-vim-for-good

This guide is coming from an email I used to send to newcomers to Vim. It is not intended to be a complete guide, it is about how I switched myself.

My decision to switch to Vim has been made a long time ago. Coming from TextMate 1, I wanted to learn an editor that is Open Source (so I don’t lose my time learning a tool that can be killed), cross platform (so I can use it everywhere), and powerful enough (so I won’t regret TextMate). For these reasons, Vim has always been the editor I wanted to learn, but it took me several years before I did it in a way that works for me. I tried to switch progressively, using the Janus Vim distribution for a few months, then got back to using TextMate 2 for a time, waiting for the next attempt… here is what finally worked for me.

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
