Utilities for working with functions.
Summary
Functions
Appends an argument to a function call, leaving the zipper at the function call's node.
Checks if the provided function call (in a Zipper) has an argument that equals
term at index.
Returns true if the argument at the provided index exists and matches the provided pattern
Returns true if the argument at the given index matches the provided predicate
Returns true if the node is a function call
Returns true if the node is a function call of the given name
Moves to a function call by the given name and arity, matching the given predicate, in the current or lower scope
Moves to a function call by the given name and arity, matching the given predicate, in the current scope
Moves to the nth argument of a function call.
Updates the nth argument of a function call, leaving the zipper at the function call's node.
Functions
@spec append_argument(Sourceror.Zipper.t(), any()) :: {:ok, Sourceror.Zipper.t()} | :error
Appends an argument to a function call, leaving the zipper at the function call's node.
@spec argument_equals?(Sourceror.Zipper.t(), integer(), any()) :: boolean()
Checks if the provided function call (in a Zipper) has an argument that equals
term at index.
Returns true if the argument at the provided index exists and matches the provided pattern
Note: to check for argument equality, use argument_equals?/3 instead.
@spec argument_matches_predicate?( Sourceror.Zipper.t(), non_neg_integer(), (Sourceror.Zipper.t() -> boolean()) ) :: boolean()
Returns true if the argument at the given index matches the provided predicate
@spec function_call?(Sourceror.Zipper.t()) :: boolean()
Returns true if the node is a function call
@spec function_call?( Sourceror.Zipper.t(), atom() | {module(), atom()}, arity :: integer() | :any ) :: boolean()
Returns true if the node is a function call of the given name
If an atom is provided, it only matches functions in the form of function(name).
If an {module, atom} is provided, it matches functions called on the given module,
taking into account any imports or aliases.
@spec move_to_def( Sourceror.Zipper.t(), fun :: atom(), arity :: integer() | [integer()] ) :: {:ok, Sourceror.Zipper.t()} | :error
@spec move_to_defp( Sourceror.Zipper.t(), fun :: atom(), arity :: integer() | [integer()] ) :: {:ok, Sourceror.Zipper.t()} | :error
move_to_function_call(zipper, name, arity, predicate \\ fn _ -> true end)
View SourceMoves to a function call by the given name and arity, matching the given predicate, in the current or lower scope
move_to_function_call_in_current_scope(zipper, name, arity, predicate \\ fn _ -> true end)
View SourceMoves to a function call by the given name and arity, matching the given predicate, in the current scope
@spec move_to_nth_argument( Sourceror.Zipper.t(), non_neg_integer() ) :: {:ok, Sourceror.Zipper.t()} | :error
Moves to the nth argument of a function call.
@spec update_nth_argument( Sourceror.Zipper.t(), non_neg_integer(), (Sourceror.Zipper.t() -> {:ok, Sourceror.Zipper.t()} | :error) ) :: {:ok, Sourceror.Zipper.t()} | :error
Updates the nth argument of a function call, leaving the zipper at the function call's node.
