Overview

Package envflag is a simple library for associating environment variables with flags.

If using the default flag.CommandLine FlagSet, just call envflag.Parse() instead of flag.Parse().

Assign environment variables to flags using the Map type:

var m := envflag.Map{
    "MY_ENV_VAR": "my-flag"
}

If the flag and the environment variable is set the flag takes precidence.
