Functions

func Handler

func Handler() http.Handler

Handler returns the env HTTP Handler.

This is only needed to install the handler in a non-standard location.

func Parse

func Parse()

Parse is equivalent to ParseWithExitFn(os.Exit).

func ParseWithExitFn

func ParseWithExitFn(exitFn func(int))

ParseWithExitFn registers command line arguments -env-check, -env-dump, -env-dump-yaml and calls env.Parse(). Any errors are written to stderr and then exitFn(1) is called.

Registered flags: -env-dump: skips parsing step and writes each env.Var to stderr, calls exitFn(0) when done. -env-dump-yaml: skips parsing steps and write each env.Var to stderr in YAML format, calls os.Exit(0) when done. -env-check: calls exitFn(0) if env.Parse() succeeds without error.
