{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Implement import by using importlib","articleBody":"The standard library for Python contains importlib, which contains a pure* Python implementation of the import machinery. This is lucky as we then don't have to implement it all in Rust. But we have to bootstrap it and implement all of the functionality it uses from builtin modules.\r\n\r\nThis is blocked by the following:\r\n- [ ] compile should accept bytes as well as strings\r\n- [x] _os.fspath - https://docs.python.org/3/library/os.html#os.fspath\r\n- [x] sys.implementation.cache_tag  - This just needs to exist we don't support caching bytecode at the moment\r\n- [ ] sys.pycache_prefix  - same as above\r\n- [x] sys.flags\r\n- [x] str.endswith needs to support tuple argument\r\n- [ ] _io.FileIO \\_\\_enter\\_\\_ and \\_\\_exit\\_\\_ methods\r\n- [x] sys.platform\r\n- [x] os.getcwd\r\n- [x] os.stat st_mtime attribute\r\n- [x] _warnings module\r\n- possibly more\r\n\r\n\\* Uses built-in module _imp to actually create module objects.
