[ruby-core:80110] [Ruby trunk Feature#6284] Add composition for procs
From:
matz@...
Date:
2017-03-13 08:13:31 UTC
List:
ruby-core #80110
Issue #6284 has been updated by Yukihiro Matsumoto.
I want to make sure if everyone agrees with "*" instead of OP's "<<".
Besides that I also wanted to mention that Koichi concerns that function composition may be far slower than method chaining.
Matz.
----------------------------------------
Feature #6284: Add composition for procs
https://bugs.ruby-lang.org/issues/6284#change-63536
* Author: Pablo Herrero
* Status: Feedback
* Priority: Normal
* Assignee: Yukihiro Matsumoto
* Target version:
----------------------------------------
=begin
It would be nice to be able to compose procs like functions in functional programming languages:
to_camel = :capitalize.to_proc
add_header = ->val {"Title: " + val}
format_as_title = add_header << to_camel << :strip
instead of:
format_as_title = lambda {|val| "Title: " + val.strip.capitalize }
It's pretty easy to implement in pure ruby:
class Proc
def << block
proc { |*args| self.call( block.to_proc.call(*args) ) }
end
end
=end
