# This workflow runs on Gitea Actions, which is API-compatible with GitHub Actions.
# It performs CI on every push to main and every pull request, and automatically
# builds and attaches a Linux amd64 release binary when a version tag (v*) is pushed.
#
# Go is installed manually from a Chinese mirror (NJU) instead of using
# actions/setup-go, because the runner is in a region where the official Go
# download endpoint is slow. GOPROXY is set to goproxy.cn for the same reason.
