Getting psf/black compiled with mypyc for performance improvements. In particular, this hosts the automated wheel building configuration.

Black + mypyc

Hello! You've found the home base for the ongoing work getting psf/black compiled with mypyc. Mypyc is a compiler for typed Python code. The end goal is to increase runtime performance. Since Black is already a well typed project with type checking provided by mypy, mypyc won out over other options like Cython. Although using mypyc isn't all smooth sailing, there's a lot of infrastructural and tuning work to be done (not to mention compatibility work since mypyc is in alpha). All of that is tracked here.

The issue tracker details specific TO-DOs and goals, while the "Getting Black compiled with mypyc" project is intended as a general overview of what has been done and what's still pending.

The project is led by @ichard26.

Thank you to @JelleZijlstra for their support and insights while I debugged or tried to understand mypy[c]'s quirks.

Many thanks goes to @msullivan for laying the groundwork that this project stands on, and to the mypyc team for building the tool.

Finally, thank you to everyone else who chipped in whose name I have forgetten (sorry!).
