code_zipper(Root::ktn_code:tree_node(), Mode::content | all) -> zipper:zipper()

exported_functions(X1::ktn_code:tree_node()) -> [{atom(), integer()}]

Takes the root node of a parse_tree and returns name and arity of each exported function.

Same as calling find/3 with #{mode => node, traverse => content} as the options map.

Find all nodes in the tree for which the predicate function returns true. The options map has two keys:

- mode: when the value node is specified the predicate function receives a tree_node() as its argument. When zipper is specified the argument is the zipper location for the current node.
- traverse: the value content indicates to only take into account nodes in the parent-child hierarchy. When all is provided the nodes held in the node_attrs map are also taken into account in the search.

find_by_location(Root::ktn_code:tree_node(), Location::{integer(), integer()}) -> not_found | {ok, ktn_code:tree_node()}

find_token(Root::ktn_code:tree_node(), Location::{integer(), integer()}) -> not_found | {ok, map()}

function_names(X1::ktn_code:tree_node()) -> [atom()]

Takes the root node of a parse_tree and returns the name of each function, whether exported or not.

module_name(X1::ktn_code:tree_node()) -> atom()

Takes the root node and returns the module's name.

past_nesting_limit(Node::ktn_code:tree_node(), MaxLevel::integer()) -> [{ktn_code:tree_node(), integer()}]

Takes a node and returns all nodes where the nesting limit is exceeded.

print_node(Node::ktn_code:tree_node()) -> ok

Debugging utility function.

print_node(Node::ktn_code:tree_node(), CurrentLevel::integer()) -> ok
