My early contributions to https://github.com/jart/cosmopolitan were focused towards getting a single-file Python executable. I wanted my Python scripts to run on both Windows and Linux, and now they do. To try out Pyth

I've tried nuitka before, and a recent question that occurred to me was: does nuitka have an option to output just C files? Something like: python -m nuitka example.py --no-compile Might be interesting to see if the above is pos

Hey, this is my post from 2021, when I was testing Python2.7 and Python3.6 with Cosmopolitan Libc on an old 4-thread Haswell. It's now a lot easier to build Python (and gcc, gnu coreutils, curl etc.), and the binaries are faster, multi

What packages do you use in your app? If you're not using too many C extensions, it may be possible to build your app with Cosmopolitan.

Try it out! We got Lua/LuaJIT, Python, PHP, and Rust building (the latter two are not fully automatic yet), so Ruby might be possible even now.

Yes, so pip works because the Python APE has OpenSSL built-in. pip install requires modifying the APE, so I end up installing pure-Python libraries as follows: mkdir Lib ./python -m pip download httpx unzip ./*.whl -

The "/zip/" folder refers to the ZIP store inside the actually portable executable -- you can run `unzip -vl ./python` to see what's inside. Also, to add new pure-python packages, you just need to unzip them in

Thank you Gregory for writing this post. There have been a bunch of announcements about "setup.py has been deprecated", but few have clearly outlined how to move away from setup.py, and more importantly, fewer have outlined what a

One of the comments in the OP: I believe the problem is that bridge in the US (not true in some other countries) lacks a "critical mass" of 20 and 30 somethings. I like to play bridge, but all the people I have asked in my

"Python 4, but not really", because we want to squeeze out more multithreading performance and be cool again. Some questions from reading the OP: - How much does performance improve due to this No-GIL thing? Is it greater than 2x?

I had tried to build a bunch of different codebases (git, bash, gcc, curl etc.) before trying busybox, and I'd never seen code like that before. Plus that error came alongside a compiler error in my patch that took a long time to debug

New constants do make compilation a lot easier, but my personal opinion is that the overhead to convert to/from the old constants during runtime is too much. Look at the list of constants here: https://github.com/jart&#

Yeah I found out I got banned when attempting to comment about this blog post. I rarely comment on online forums anyway, because I find I don't know enough to comment about most topics. IIRC over the last year, I've only commented

Right now I use the gcc, git, vim, and ninja APE binaries on my local system for daily work, and so far I have seen no visible regressions. I agree with you though -- an extensive testing setup will reveal more things for improvement, be it

Reading the GCC source code was fun and educational, and I'd love to find out if this could patch make it into GCC. Haven't discussed it with any of the GCC developers yet. In the meantime, the Cosmopolitan Libc monorepo contains

I haven't used Nim much, but I remember a repo on Github had setup a build script for compiling Nim with Cosmopolitan Libc. https://github.com/Yardanico/cosmonim This gcc patch makes such build scripts simpler, be

Yes, I have gotten busybox to build successfully, but at present it's not as nice as bash or vim. I expect someone will write a better build script soon enough. Maybe it will be you! The default build parameters in busybox make a lot o

Dereferencing the runtime symbol with a function sounds interesting! If you can show me an example of where it works, I'd be happy to try it out. I like the if-else-goto arrangement because it fit in perfectly with the other parts of g
