So that it can be installed via sudo port install shadowsocks-rust. MacPorts only have libev C implementation at the moment.

I thought macOS users should prefer HomeBrew than MacPorts.

@zonyitoo homebrew installs from git repos and to a home dir instead of system wide. homebrew also pulls a bunch of uneeded crap unfortunately.

Do you know how to make a Portfile for this project and update it automatically (maybe with github action)?

[talentlessguy]

yes, and the portfile needs to be added to this GitHub repo:
