########## Web Application Development for BASH made easy
# This shell script contains a collection of excellent scripts I've found over the years that enhance development.
# It is organized much like a traditional etc/*conf file, and I hope others find it useful.
#
# YOU MUST HAVE X-CODE installed
#
# Features include:
#     - Homebrew
#     - Sexy git bash status prompt
#     - NodeJS Version Manager (nvm)
#     - Ruby Version Manager (rvm)

##### Configuration

# Allows NodeJS to open a lot of files concurrently, fixes issues with certain node modules like grunt
ulimit -n 10000

##### Homebrew - Unix tools & open source software
# package manager for Mac OS X
# http://coolestguidesontheplanet.com/installing-homebrew-os-x-yosemite-10-10-package-manager-unix-apps/

# Homebrew Path Variables
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export PATH=/usr/local/bin:$PATH

##### NodeJS
# http://www.nodejs.org
#
# This script uses the NodeJS Version Manager
# https://github.com/creationix/nvm
# Sets the default NodeJS-RunTime environment variable (NODE_ENV)
#SET Node_ENV=production
export NODE_ENV=development

# creates alias for nvm command to point to nvm.sh
export PATH="$PATH:$HOME/.nvm/bin"
[ -s "$HOME/.nvm/nvm.sh" ] && . "$HOME/.nvm/nvm.sh"  # This loads nvm
