| This directory contains Python code for running pytype (a Python 3 type hinting |
| analyzer) on Chromium Python code. pytype can infer types from un-annotated |
| code, so it is not necessary to have type hinting added for all analyzed code |
| and its dependencies. However, it is still recommended to do so eventually to |
| ensure that the type hinting is as accurate as possible and to ensure that |
| humans have up-to-date information about what functions take and return. |
| |
| |
| To run pytype, simply import `pytype_runner.py` and call its `run_pytype` |
| function with the correct arguments as specified in its docstring. |
| |
| It is recommended to NOT run this as part of presubmit, as depending on how many |
| dependencies your code has, it can end up analyzing many files and taking |
| multiple minutes. This time goes down dramatically once pytype has a cache |
| built, but there is currently no way to ensure bots have a warm cache, so it |
| should not be relied on. |
