README

This is a testing tool for the --socket option, which can also be used by third-parties to check compatibility.

Install

cargo install --git https://github.com/watchexec/watchexec test-socketfd

Usage

Print the control env variables and the number of available sockets:

test-socketfd

Validate that one TCP socket and one UDP socket are available, in this order:

test-socketfd tcp udp

The tool also supports unix-stream, unix-datagram, and unix-raw on unix, even if watchexec itself doesn't. These correspond to the ListenFd methods here: https://docs.rs/listenfd/latest/listenfd/struct.ListenFd.html
