}

[−] Expand description

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).

Fields

args: List<Node>

[−] Expand description

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)

begin_l: MaybeLocPtr

[−] Expand description

Location of the open parenthesis

proc { |(foo, bar)| }
        ~

None if there’s only one argument

end_l: MaybeLocPtr

[−] Expand description

Location of the open parenthesis

proc { |(foo, bar)| }
                 ~

None if there’s only one argument

expression_l: LocPtr

[−] Expand description

Location of the full expression

proc { |(foo, bar)| }
