Automatic git branch switching based on substrings

.bashrc

alias fb="ruby ~/find_branch.rb $1"

find_branch.rb

# I hate git autocompletion with the white hot intensity of a
# thousand burning suns. This works better for me.

req = ARGV[0]
branches = `git branch | grep '#{req}'`
branch_list = branches.split(' ')

if branch_list.length > 1
    puts
    puts 'Found the following branches: '
    puts
    branch_list.each_index do |i|
        puts '    ' + i.to_s + '. ' + branch_list[i]
    end
    puts
    print "Which one do you want? "
    to_get = STDIN.gets.chomp.to_i
    `git checkout #{branch_list[to_get]}`
elsif branch_list.length == 1
    `git checkout #{branches}`
else
    puts "No branch found"
end

Fyi for any bash-newbies who'd visit this: put the first part in your ~/.bash_profile instead.

Other than that this is really awesome.
