It even includes support for JIT builds.

If you pass in --jit to a build, every-python will attempt to detect the correct version of LLVM needed to build from LLVM_VERSION specified in Tools/jit/_llvm.py at the time of the commit and use it!

Makes bisecting JIT things so much simpler 🥲

Coming soon to a compute near you - every-python!

Build and run any commit of CPython! every-python makes a blobless clone of the CPython repository (~200MB), checks out the version you want, and builds it locally. Built versions are cached for reuse.

He is not much of a cuddler with the other cats and is very pro-nap. #TeamAkio

With every #SavannahCat hashtag, I feel like it’s a post addressed specifically to me because you know I also have cats…and so I must oblige with a picture of Momo.

I put up a bunch of Halloween decorations last night and Momo is not having it. A very jumpy boy today, slapping anything he’s unsure of.
