Overcommit setup for Rails apps
# Use this file to configure the Overcommit hooks you wish to use. This will
# extend the default configuration defined in:
# https://github.com/brigade/overcommit/blob/master/config/default.yml
#
# At the topmost level of this YAML file is a key representing type of hook
# being run (e.g. pre-commit, commit-msg, etc.). Within each type you can
# customize each hook, such as whether to only run it on certain files (via
# `include`), whether to only display output if it fails (via `quiet`), etc.

# For a complete list of hooks, see:

The introduction to Reactive Programming you've been missing

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

Using RVM in Sublime Text 2

Start with:

subl ~/Library/Application\ Support/Sublime\ Text\ 2/Packages/Ruby/Ruby.sublime-build

Copy and paste this, replacing the contents of that file with this:

  "env":{
 "PATH":"${HOME}/.rvm/bin:${PATH}"

Creating a valid email address from a name and email, using the Ruby Mail library. Used to prevent invalid headers.

If you are taking user input for name and email, then unless you very carefully validate or escape the name and email, you can end up with an invalid From header by simply concatenating strings. Here is a safe way:

require 'mail'
address = Mail::Address.new email # ex: "john@example.com"
address.display_name = name # ex: "John Doe"
# Set the From or Reply-To header to the following:
address.format # returns "John Doe <john@example.com>"
