* Package name : mypyc Version : 0.0.git.20190713T1002.833151a+ds1 Upstream Author : Copyright: © 2017-2018 Jukka Lehtosalo and contributors * URL : http://www.mypy-lang.org/ * License : Expat Programming Lang: C Description : Mypy to Python C Extension Compile *Mypyc is (mostly) not yet useful for general Python development.* . Mypyc is a compiler that compiles mypy-annotated, statically typed Python modules into CPython C extensions. Currently our primary focus is on making mypy faster through compilation -- the default mypy wheels are compiled with mypyc. Compiled mypy is about 4x faster than without compilation. . Mypyc compiles what is essentially a Python language variant using "strict" semantics. This means (among some other things): . * Most type annotations are enforced at runtime (raising ``TypeError`` on mismatch) . * Classes are compiled into extension classes without ``__dict__`` (much, but not quite, like if they used ``__slots__``) . * Monkey patching doesn't work . * Instance attributes won't fall back to class attributes if undefined . * Metaclasses not supported . * Also there are still a bunch of bad bugs and unsupported features :) . Compiled modules can import arbitrary Python modules, and compiled modules can be used from other Python modules. Typically mypyc is used to only compile modules that contain performance bottlenecks. . You can run compiled modules also as normal, interpreted Python modules, since mypyc targets valid Python code. This means that all Python developer tools and debuggers can be used. . This package provides the command-line interface.
