uv.rb - libuv FFI bindings for Ruby

Libuv is a cross platform asynchronous IO implementation that powers NodeJS. It supports sockets, both UDP and TCP, filesystem operations, TTY, Pipes and other asynchronous primitives like timer, check, prepare and idle.

UV.rb is FFI Ruby bindings for libuv.

Usage

Create a uv loop or use a default one

require 'uv'

loop = UV::Loop.default
# or
# loop = UV::Loop.new

timer = loop.timer
timer.start(50000, 0) do |error|
  p error if error
  puts "50 seconds passed"
  timer.close
end

loop.run

Installation

gem install uvrb

or

git clone ...
cd ...
bundle install

Make sure you have libuv compiled and a shared library (.dylib|.so|.dll) file available in your lib path.

To compile libuv from a local submodule version:

git submodule update --init
rake libuv

Or to compile libuv on mac, you can install provided Homebrew formula by running:

brew install Formula/libuv.rb --HEAD
