CrSignals Build Status Release

CrSignals is a signals/slots library. You can define your signal/slot function, wire them and emit data.

Installation

  1. Add the dependency to your shard.yml:
   dependencies:
     CrSignals:
       github: firejox/CrSignals
  1. Run shards install

Usage

  • Here is a basic example of CrSignals library.
require "CrSignals"

class Foo
  include CrSignals::Generator

  property x : Int32 = 0

  cr_signal value_change(Int32)

  def set_x(v : Int32)
    if @x != v
      @x = v
      value_change(v)
    end
  end
end

a = Foo.new
b = Foo.new

a.connect_value_change(->b.set_x(Int32))

a.set_x(3)
puts b.x # => 3

a.disconnect_value_change(->b.set_x(Int32))

a.set_x(4)
puts b.x # => 3
  • If you operate with incorrect type, it will report a compile error.
require "CrSignals"

class Foo
  include CrSignals::Generator

  property x : Int32 = 0

  cr_signal value_change(Int32)

  def set_x(v : Float64); end
end

a = Foo.new
b = Foo.new

a.connect_value_change(->b.set_x(Float64)) # compile error
