request: support installation on alpine

[aviad-dev]

When trying to install clipspy on an alpine-based docker image (see Dockerfile below), I get an error (see below). I have been able to install clips on alpine without clipspy using make release and CLIPS's makefile (see last docker file below).

I'd be happy to try and help making clipspy installable on alpine as well, as this is a popular docker image for running python. I'd just be happy to get some help understanding why clipspy is building CLIPS as it does.

Dockerfile for installing clipspy:

FROM python:3.12-alpine

RUN apk add build-base curl make
RUN pip install clipspy

CMD ["python", "-c", "'from clips import __version__; print(__version__)'"]

Error when running the above:

Hello,

it appears your installer is fetching the wrong package. You need to check what pip is doing within your dockerfile.

Your Docker instance should not install clipspy-1.0.4.tar.gz which is the source build but this package which is the binary release instead.

Ok, I guess your issue depends on this. I remember Docker was introduced to simplify deployments across multiple environments and Linux distributions... 🤦
