+- `indicator_size` - How long should the string be. If longer, it is cut from
+  the beginning.
+- `type_patterns` - Which node type patterns to match.
+- `transform_fn` - Function used to transform the single item in line. By
+  default removes opening brackets and spaces from end.
+- `separator` - Separator between nodes.
