== Live

Live is like irb only it is meant to be used from a text editor, it essentially polls a *nix pipe and evaluates its contents. 
It was devised for audiovisual livecoding (ruby-processing and scruby), a block can be bound to a key and can be called later by a keystroke.

== Install

    $ [sudo] gem install live


== Usage

    $ live

open a new terminal

    $ echo ' "hello" ' > /tmp/live-rb

You will see the code evaluated in the first terminal

    $ echo 'bind_key(:a){ "key a was pressed" }' > /tmp/live-rb

When you press the key 'a' with focus on the first terminal it will call the block


== Vim

To use from vim paste this in your .vimrc file

    function EvalLiveRuby() range
      let text = [join(getline(a:firstline, a:lastline), ';')]
      return writefile(text, '/tmp/live-rb')
    endfunction

    map <Leader>x :call EvalLiveRuby()<enter>

Then by pressing leader and x you will execute the range in the live session
