Summary

Types

equality_pred()

Functions

append_new_to_list(zipper, quoted, equality_pred \\ &Common.nodes_equal?/2)

Appends quoted to the list unless it is already present, determined by equality_pred.

append_to_list(zipper, quoted)

Appends quoted to the list

do_move_to_list_item(zipper, pred)

Moves to the list item matching the given predicate, assuming you are currently inside the list

find_list_item_index(zipper, pred)

Finds the index of the first list item that satisfies pred

list?(zipper)

Returns true if the zipper is at a list literal

map(zipper, fun)

Moves to the list item matching the given predicate

move_to_list_item(zipper, pred)

Moves to the list item matching the given predicate

prepend_new_to_list(zipper, quoted, equality_pred \\ &Common.nodes_equal?/2)

Prepends quoted to the list unless it is already present, determined by equality_pred.

prepend_to_list(zipper, quoted)

Prepends quoted to the list

remove_from_list(zipper, predicate)
remove_index(zipper, index)

Removes the item at the given index, returning :error if nothing is at that index

replace_in_list(zipper, predicate, value)

Functions

append_new_to_list(zipper, quoted, equality_pred \\ &Common.nodes_equal?/2)

@spec append_new_to_list(Sourceror.Zipper.t(), quoted :: Macro.t(), equality_pred()) ::
