LocalVariableReadNode

Type: PM_LOCAL_VARIABLE_READ_NODE

@extends pm_node_t

Fields

base: pm_node_t

The embedded base node.

name: pm_constant_id_t

LocalVariableReadNode#name

The name of the local variable, which is an identifier.

 x      # name `:x`

 _Test  # name `:_Test`

Note that this can also be an underscore followed by a number for the default block parameters.

 _1     # name `:_1`

Finally, for the default it block parameter, the name is 0it. This is to distinguish it from an it local variable that is explicitly declared.

 it     # name `:0it`

depth: u32

LocalVariableReadNode#depth

The number of visible scopes that should be searched to find the origin of this local variable.

 foo = 1; foo # depth 0

 bar = 2; tap { bar } # depth 1

The specific rules for calculating the depth may differ from individual Ruby implementations, as they are not specified by the language. For more information, see the Prism documentation.
