How to install and use Redis with Ruby
git clone git://github.com/ezmobius/redis-rb.git
cd redis-rb/
rake redis:install
rake dtach:install
rake redis:start &
rake install
cat <<EOF >>test.rb
require 'rubygems'
require 'redis'
r = Redis.new
r.delete('foo')
p'set foo to "bar"'
r['foo'] = 'bar'
p 'value of foo'
p r['foo']
EOF
ruby test.rb
If Redis is not started Ruby will exit at Redis.new for some reason without saying anything.
