Method: YARD::CodeObjects::MacroObject.expand

Defined in:
lib/yard/code_objects/macro_object.rb

.expand(macro_data, call_params = [], full_source = '', block_source = '') ⇒ Object

Expands macro_data using the interpolation parameters.

Interpolation rules:

  • $0, $1, $2, … = the Nth parameter in call_params

  • $* = the full statement source (excluding block)

  • Also supports ${N-M} ranges, as well as negative indexes on N or M

  • Use $ to escape the variable name in a macro.
