mruby-partcont

partial continuation support for mruby.

Install

MRuby::Build.new do |conf|

    # ... (snip) ...

    conf.gem :github => 'wasabiz/mruby-partcont'
end

mruby-partcont does not depends on other libraries or extensions, but for the safety it is highly recommended to add at the end of the gem build conf.

Example

reset {
  p 1
  shift {|k|
    p 2
	k.call()
	p 3
  }
  p 4
}
# 1
# 2
# 4
# 3
# => nil

APIs

• Continuation class

Represents a delimited continuation that cuts the process from where the shift operator is called up to the nearest reset operator. Since continuations have infinite extent, once they are created it is possible to call them anytime anywhere, and even however many times. When the continuation is cut (making a continuation closure), the bottom of the stack of the delimited continuation is dynamically chosen.

• Kernel.#reset { ... } -> value
• Kernel.#shift {|k| ... } -> value
