Is this maintained?

I'm trying to use nanomsg because ZMQ doesn't have a good implementation in Rust. However, I'm having trouble finding the Python library. I cannot compile pynng on my Mac M1 and this library has only one version (1.0.0) available in PIP and doesn't have any description.

Are you still maintaining this library or are there any good Python bindings?

As far as I know this is still the best option for Python binding. As for if this library is maintained you'd be a better judge of that than me.

Thanks for your reply, Tony. I'm getting the following error when compiling on Mac M1:

error: command '/usr/bin/clang' failed with exit code 1

The main error ld: library not found for -latomic seems to be resolved by removing -latmoice from the linking step. So, instead, I can do:

clang -bundle -undefined dynamic_lookup build/temp.macosx-12-arm64-cpython-310/build/temp.macosx-12-arm64-cpython-310/pynng._nng.o ./nng/build/libnng.a ./mbedtls/prefix/lib/libmbedtls.a ./mbedtls/prefix/lib/libmbedx509.a ./mbedtls/prefix/lib/libmbedcrypto.a -lpthread ~-latomic~ -o build/lib.macosx-12-arm64-cpython-310/pynng/_nng.abi3.so

Then I can python setup.py install and I can import it fine. I'm testing now whether it works

I'm sorry, I was not paying attention to what I was posting. Apologies. I also realised that NNG is not the same as nanomsg and it seems to be better to stick to the newer NNG (so the only binding is pynng)
