| 5 // This executes a very simple search for all functions that call a | |
| 6 // given set of functions. It's intended to be the simplest possible | |
| 7 // way of refactoring a common pattern of function calls. Of course, | |
| 8 // it's still up to a human to decide if the replacement is truely | |
| 9 // suitable, but this gets the low-hanging fruit. | |
| 10 | |
| 11 // Expects the variable 'patterns' to hold an object with replacement | |
| 12 // function names as keys and function lists as values. Any function | |
| 13 // in the tested source that calls all of the functions named in the | |
| 14 // list will be listed in the output as being likely candidates to | |
| 15 // instead call the replacement function. | |
