Publish it on GitHub (or GitLab or your code hosting service of choice). Then answer any criticism about it by asking for a PR. To preempt code style complaints find a code formatter for your language and run everything through that first. Refer to the repository in your paper, but don't put a link. Create a little bit of friction to get to the repo to discourage the casual readers who don't really need the code from popping over too easily.
