Using Obj-C with MacRuby/Rubymotion

This little post aims to help you to translate Objective-C Blocks into Ruby blocks. Let's start by taking a look at few examples of iOS API call where blocks are used for animations and enumeration

Ruby Lambda Syntaxes:

Im Rubymotion and MacRuby you can use all the Ruby Lambda syntaxes that are:

block = lambda { |param|  ... }

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

	# There was a day where I have too many color schemes in iTerm2 and I want to remove them all.
	# iTerm2 doesn't have "bulk remove" and it was literally painful to delete them one-by-one.

	# iTerm2 save it's preference in ~/Library/Preferences/com.googlecode.iterm2.plist in a binary format
	# What you need to do is basically copy that somewhere, convert to xml and remove color schemes in the xml files.

	$ cd /tmp/
	$ cp ~/Library/Preferences/com.googlecode.iterm2.plist .
	$ plutil -convert xml1 com.googlecode.iterm2.plist
	$ vi com.googlecode.iterm2.plist

	term = "Star Trek"
	guessed_term = "** **"

	puts "Welcome to the Hangman!"
	puts "You are going to guess this movie: "
	puts "** **"
	puts ""
	puts "Start with guessing letters, you have in total 3 attempts"
	puts "At any times you can also guess the full term!"
	puts "So let's start!"

	# change prefix to Ctrl-a (like in gnu-screen)

	unbind C-b
	set-option -g prefix C-a
	bind-key C-a send-prefix


	# shell
	set -g default-command /bin/zsh
