Relative paths for wavedrom-cli about sphinx-wavedrom

Hi!

I don't normally install Node or NPM on my machines.

I don't think you're the only one, so I think it's worth supporting it somehow. I'd be hesitant to just flip the switch on this entirely, but I think we can add an option for it.

Is your approach similar to this one? https://github.com/mvonbun/docker-wavedrom-cli. I'm asking cause I'd like to reproduce the issue and add a link in the readme, as this will likely help others as well.

@bavovanachte, sorry for the delay.

I think my approach is a bit simpler than the one you linked, but I'm not terribly familiar with the NPM ecosystem, so I don't know how they compare.

Here is my Dockerfile:

FROM docker.io/library/node:12.0

RUN npm -g config set user root \
 && npm i wavedrom-cli -g

ENTRYPOINT ["wavedrom-cli"]

And here is my wrapper script:

#!/bin/bash

args=("$@")
for i in "${!args[@]}"; do
  if [[ "${args[$i]}" = /* ]]; then
    args[$i]=$(realpath --relative-to="$PWD" "${args[$i]}")
  fi
done
podman run --rm -v "$PWD":/wavedrom -w /wavedrom localhost/wavedrom-cli ${args[@]}
