  • Any other symbol is replaced with the value of illust.send(the_symbol)

  • #call-able object is replaced with the value of the_object.call(illust)

  • String is left as-is

Parameters:

  • pattern (Array<String, Symbol, #call>)
  • illust (Pixiv::Illust)
  • url (String)

Returns:

  • (String) —

    filename
