One of the many reasons I love working with Ruby is it has a rich vocabulary that allows you to accomplish your goals with a minimal amount of code. If there isn't a method that does exactly what you want, it's usually possible to build an elegant solution yourself.
Let's take the example of simulating the rolling of a die.
We can represent a die as an array of its faces.
die = [*?⚀..?⚅]
# => ["⚀", "⚁", "⚂", "⚃", "⚄", "⚅"]
| # Elixir has pipes `|>`. Let's try to implement those in Ruby. | |

| # I want to write this: | |
| # | |
| # email.body | RemoveSignature | HighlightMentions | :html_safe | |
| # | |
| # instead of: | |
| # | |
| # HighlightMentions.call(RemoveSignature.call(email.body)).html_safe | |

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000
| # Ship it! rake task | |

| # Merge branch (master by default) to deployment branch, and deploy to server. | |
| # | |
| # Prerequisite: | |
| # | |
| # * Declare all deployment branches in `ALL_DEPLOYMENT_BRANCHES` | |
| # * Declare deploy only branches in `DEPLOY_ONLY_BRANCHES` (ie, does not merge master) | |
| # * Modify `Deploy.command` function as necessary | |

Locate the section for your github remote in the .git/config file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
| # | |
| # Eric Lindvall <[email protected]> | |

| # Update the process name for the process you're running in. | |

| # This will allow top, lsof, and killall to see the process as the | |
| # name you specify. | |

| # Just use: | |
