# A simple Makefile alternative to using Grunt for your static asset compilation
#
## Usage
#
#   $ npm install
#
# And then you can run various commands:
#

# Usage: link_to …, prompt: { message: 'Some message', default: 'default value', param: 'name of parameter' }
# The prompt will ask for "message" and use "default" as the default value.
# Unless user selects cancel, "param"=<new value> will be sent to the given path.
# Optionally, you can just use `prompt: "message"`.

$.rails.prompt = (message, defaultValue) ->
  window.prompt message, defaultValue
  
$.rails.handlePrompt = (element) ->
  config = element.data 'prompt'

# Find and replace text in multiple files
# http://www.24hourapps.com/2009/03/linux-tips-17-find-and-replace-text-in.html

# Multiple file find and replace is a rarely used, but an extremely time saving, ability of
# Linux that I cannot live without. It can be achieved by chaining a few commands together
# to get the list of files you want to change (find), make sure the files contain the strings
# you want to replace (grep), and do the replacements (sed).

# Lets say we have a lot of code that uses the function registerUser that was implemented when
# there was only one class of users, but now another class of users need to access the system
