Copy, with line wrapping!

If you've been trying to copy/paste text from a multi-pane tmux session with the mouse, you've probably been pretty pissed at the blissful ignorance a terminal application has of the rodent in your hand.

The alternative, which is quote-unqoute native copy/pasting using copy-mode takes a bit to get used to. So this is one solution for copying and pasting lines from a session with correct line wrapping behaviour, albeit keyboard only.

Disclaimer

Since copy-mode has similar concepts of marks, regions, and temp buffers to Emacs .. you'll probably find it straight forward if you're familar with Emacsen. For people using vi-mode in tmux, the same still applies but obviously the default key bindings will differ alot from what I show below.

Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo

# Ensure system is in ship-shape.

aptitude install git zsh libssl-dev zlib1g-dev libreadline-dev libyaml-dev

Patched ruby 1.9.3-p194 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p194 with patches for boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Huge thanks to funny-falcon for the performance patches.

Most examples I found tell you to run rvmsudo or passenger-install-nginx-module. I ran into problems with these because:

rvmsudo leaves root owned directories and files under rvm passenger gem directory. This will give you seemingly odd errors later when you try to remove/upgrade passenger gem, or try to use homebrew to install passenger.
There's no good place to put nginx using passenger-install-nginx-module. Putting it under /usr/local means you have to remember it's there amongst homebrew files. Anywhere else, you still have to remember you put it there. We'd rather manage nginx install via homebrew.

So to install everything with homebrew, this is what it took:

gem install passenger


	namespace :attachments do
	task :migrate_to_s3 => :environment do
	require 'aws/s3'

	# Load credentials
	s3_options = YAML.load_file(File.join(Rails.root, 'config/s3.yml')).symbolize_keys
	bucket = s3_options[:bucket_name]

	# Establish S3 connection

	# app/models/ability.rb

	# All front end users are authorized using this class
	class Ability
	include CanCan::Ability

	def initialize(user)
	user \|\|= User.new

	can :read, :all

	# Install Bash 4 using homebrew
	brew install bash

	# Or build it from source...
	curl -O http://ftp.gnu.org/gnu/bash/bash-4.2.tar.gz
	tar xzf bash-4.2.tar.gz
	cd bash-4.2
	./configure --prefix=/usr/local/bin && make && sudo make install

	# Add the new shell to the list of legit shells

	guard 'rspec', :version => 2 do
	watch(%r{^spec/.+_spec\.rb$})
	watch(%r{^lib/(.+)\.rb$}) { \|m\| "spec/lib/#{m[1]}_spec.rb" }
	watch('spec/spec_helper.rb') { "spec" }

	# Rails example
	watch(%r{^app/(.+)\.rb$}) { \|m\| "spec/#{m[1]}_spec.rb" }
	watch(%r{^app/(.*)(\.erb\|\.haml)$}) { \|m\| "spec/#{m[1]}#{m[2]}_spec.rb" }
	watch(%r{^app/controllers/(.+)_(controller)\.rb$}) { \|m\| ["spec/routing/#{m[1]}_routing_spec.rb", "spec/#{m[2]}s/#{m[1]}_#{m[2]}_spec.rb", "spec/acceptance/#{m[1]}_spec.rb"] }
	watch(%r{^spec/support/(.+)\.rb$}) { "spec" }
