docopt

Overview ¶

Command docopt demonstrates binding docopt to a struct via env.

It uses a simple implementation of env.Env to map environment variable names to docopt options (e.g. LOG_LEVEL -> --log-level), and to cast the limited types returned by docopt to strings.

USERNAME=bob go run docopt_example.go --cache-path /var/cache
// Output:
// CachePath=/var/cache
// Username=bob
// ...
// ...
