envflag

func Parse ¶

func Parse()

Parse parses environment vars and command-line flags.

Flags set via command-line override flags set via environment vars.

This function must be called instead of flag.Parse() before using any flags in the program.

func ParseFlagSet ¶

func ParseFlagSet(fs *flag.FlagSet, args []string)

ParseFlagSet parses the given args into the given fs.

func ParseFlagSetErr ¶

func ParseFlagSetErr(fs *flag.FlagSet, args []string) error

ParseFlagSetErr behaves like ParseFlagSet but returns an error instead of calling log.Fatalf. Use this when the caller prefers to handle parse errors instead of exiting the process.
