== 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
