A toy example of defining filter and sorting operations in one place (on a class) while still keeping collections generic.
# An idea on how to sort and filter Ruby collections in a functional
# style
# Just using Struct for convenience, this could be a normal class.
User = Struct.new(:first_name, :last_name, :admin) do
def self.sort_by_name
# Define a new sort
lambda do |x,y|
# last name, first name DESC

script to compare all branches by date of most recent commit. silences `stderr` because otherwise git tells you every time it switches branches
function silencing_stderr() {
$* 2>/dev/null
}
function branch_names() {
git br | awk '{print $1}' | grep -v '*' | xargs
}
function most_recent_commit() {
git log . | grep "Date: " | cut -c 9- | head -1

A VERY partial implementation of .gitignore semantics in Ruby...
#!/usr/bin/env ruby
require 'set'
# This code is meant to demonstrate the difficulty of actually applying .gitignore semantics manually. It supports a key subset of .gitignore
# behaviors, including:
# * Anchored and unanchored patterns/globs.
# * Un-ignoring of patterns/globs, with the same quirky semantics as git.
# * Escaping a leading hash in a pattern.
# * User-wide exclusion list.
# * Top-of-repo .gitignore.
