Defined in:

Overview

Represents a sole block argument (e.g. |foo|)

Block that takes a single array argument automatically expands it. Adding trailing comma after block argument disables this behavior (and then the only argument is emitted as Arg).

#args ⇒ ::Array<Node> (readonly)

Parts of the sole block argument.

proc { |(a, b)| } also counts as a sole argument, so this list may contain:

  1. A single Arg node (for proc { |a| } case)
  2. Multiple Arg nodes (for proc { |(a, b, c)| } case)
