Named Proc
¶ ↑
When working with a lot of procs, naming them might become handy. It makes identifying them later easier. For an example that uses named procs, see the multi_block gem!
Currently supports CRuby only.
Setup¶ ↑
Add to Gemfile:
gem 'named_proc'
Named Procs¶ ↑
A named proc acts like a normal proc, but it has a name attribute. You create it by calling a method with the desired name on proc
:
>> a = proc.even?{ |e| e.even? } => #<NamedProc:0x00000001ffc340@(irb):1> >> a.name => :even? >> a[42] => false
In the same way, you can create lambdas:
>> b = lambda.doubler{ |e| e * 2 } => #<NamedProc:0x000000020685e0@(irb):7 (lambda)> >> b.name => :doubler >> b[21] => 42 >> b.lambda? => true
