// This executes a very simple search for all functions that call a
|
|
// given set of functions. It's intended to be the simplest possible
|
|
// way of refactoring a common pattern of function calls. Of course,
|
|
// it's still up to a human to decide if the replacement is truely
|
|
// suitable, but this gets the low-hanging fruit.
|
|
|
|
// Expects the variable 'patterns' to hold an object with replacement
|
|
// function names as keys and function lists as values. Any function
|
|
// in the tested source that calls all of the functions named in the
|
|
// list will be listed in the output as being likely candidates to
|
|
// instead call the replacement function.
