Parsing anonymous nested structs fails

[nics]

Parsing this config struct panics on the nested struct:

type Config struct {
	Repo struct {
		Conn  string  `env:"CONN,notEmpty"`
	} `envPrefix:"REPO_"`
}

Error message:

Thanks for a handy tool!

Thanks for reporting! I'll look into this problem

The fix should be available in v0.1.1 version.

Hi @g4s8 thanks it works now. Note that I get a segfault if there is no description comment.

So this works:

type Config struct {
       // Repository configuration
       Repo struct {
		Conn  string  `env:"CONN,notEmpty"`
	} `envPrefix:"REPO_"`
}

But this segfaults:

type Config struct {
	Repo struct {
		Conn  string  `env:"CONN,notEmpty"`
	} `envPrefix:"REPO_"`
}

Sorry, my bad. The panic was fixed in v0.1.2.
