Go package to provide reasonable robust access to fully qualified hostname. It first tries to looks up your hostname in hosts file. If that fails, it falls back to doing lookup via dns.
Basically it tries to mirror how standard linux hostname -f works. For that
reason, your hosts file should be configured properly, please refer to hosts(5)
for that.
It also has no 3rd party dependencies.
This package uses go modules, so just writing code that uses it should be enough. For example of usage you can check out the example.
Documentation can be found here.
Current and current - 1 versions of go are supported.
On macos, when not using cgo (CGO_ENABLED=0), getting the fqdn hostname
might not work. Depends on rest of your setup and how /etc/resolv.conf looks
like. Since that file is not used much (at least based on documentation) by
macos programs, it is possible it is not in correct state.
