Is there a newer MagLev version?

.rvmrc

rvm --create --use maglev-24990@my_gemset
ruby update.rb

update.rb

require "open-uri"

installed = /(\d+)$/.match(ENV['RUBY_VERSION'])[1].to_i

version = `curl -s https://github.com/MagLev/maglev/raw/master/version.txt | head -n 1`.chomp.strip

latest = /([\d]+?)-\d+\)$/.match(version)[1].to_i

if (latest > installed)
  puts "*" * 75
  puts "There's a later version: #{latest}"
  puts "maglev stop"
  puts "rvm upgrade maglev-#{latest} maglev-#{installed}"
  puts "sed -i 's/#{installed}/#{latest}' .rvmrc"
  puts "*" * 75
end

# @faustroll is a regexp wizard
# @timfelgentreff on the ones and twos, and rvm upgrade

"rvm upgrade maglev-#{latest} maglev-#{current}" will install the newer version, remove the old one and migrate all your gemsets

updated, thanks!
