Named Screen

A utility inspired by @ahoward that allows screens to be the name of the directory they were spawned from. This is mainly helpful for Terminal/iTerm tabs.

Executing this should rejoin sessions with the same name if they already exist or otherwise create them.

Usage

1. Place or symlink into your path (I symlink as ns)
2. Ensure the script is executable

to_map

A to_map function is very useful when you want to convert models to PLAIN OLD DATA. Think presenters, conductors, APIs, JSON, etc...

Installation

Add this monkey-patch to your Rails project and call it on your model instances.

Example Models

/*
  As of version 1.1.2, Propane will load and execute the contents of
  ~Library/Application Support/Propane/unsupported/caveatPatchor.js
  immediately following the execution of its own enhancer.js file.

  You can use this mechanism to add your own customizations to Campfire
  in Propane.

  Below you'll find two customization examples.
