Happening

An easy way to do event-based and scheduled programming in Ruby based on libevent.

The idea, eventually, is to have asynchronous IO using Fibers which are transparent to the programmer. Originally, this was going to be called Protein (eventful fiber) which it may well end up. This is partially a learning exercise.

Example

Happening.in 5.seconds do
  puts 'Later'
end

Happening.next do
  puts 'First'
end

Happening.run do
  puts 'Now'
end

# => "First"
#    "Now"
#    (a pause)
#    "Later"

TODO

• Multiple event loops
• IO notifications
• Process notifications
• Signal handling

Caveats

• This is the first time I've written a C extension for Ruby, plus I'm a bit rusty at C. Please, be kind and tell me what I'm doing wrong.
