Take this snippet, borrowed from the coffeescript changelog:

$ 'body'
.click (e) ->
  $ '.box'
  .fadeIn 'fast'
  .addClass '.active'
.css 'background', 'white'

Calling `eh` from vim

I use vim, and I occasionally write Elixir code.

Vim has built-in support for looking up documentation, keywordprg.

So since I wanted to be able to look up Elixir documentation from vim, I wrote an elixir package called eh, which is available on hex.

To call eh from vim, add the following to your .vimrc:

	#!/usr/bin/env bash

	# only move files older than 5 days
	maxdate=$( date +%Y-%m-%d -d '5 days ago')

	# set source and destination folders unless set by env
	[ -z "$LOG_SOURCE" ] && LOG_SOURCE="/source/path"

	for file in $LOG_SOURCE/.log.; do
	# example:

	module.exports = exports = ObjectWithDefaultProperty;
	function ObjectWithDefaultProperty(properties, defaultValue) {
	return Proxy.create({
	get: function get(proxy, name) {
	if (name in properties) {
	return properties[name];
	} else {
	return defaultValue;
	}
	}

	First off, install cowsay, and some PostgreSQL language extension, like [plsh](https://github.com/petere/plsh).

	Now, make sure to install the language extension in your database:

	$ psql
	= CREATE EXTENSION plsh;

	Now what you need is a function that takes some input and prints it using cowsay:

	=# CREATE FUNCTION cowsay (input text) RETURNS text

	defmodule GoogleBooks do
	use HTTPoison.Base

	@base_url "https://www.googleapis.com/books/v1/volumes?q=isbn:"

	def process_url(isbn13) do
	isbn = String.replace(isbn13, "-", "")
	@base_url <> isbn
	end
