Defined in:

lib/lib-ruby-parser/nodes.rb

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).

Instance Attribute Summary

• #args ⇒ ::Array<Node> readonly

  Parts of the sole block argument.

• #begin_l ⇒ Loc^? readonly

  Location of the open parenthesis.

• #end_l ⇒ Loc^? readonly

  Location of the open parenthesis.

• #expression_l ⇒ Loc readonly

  Location of the full expression.

Instance Attribute Details

#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)

Returns:

• (::Array<Node>)
