Function getEnvConfig

completions.go:1014–1020

getEnvConfig returns the value of the configuration environment variable <PROGRAM>_<SUFFIX> where <PROGRAM> is the name of the root command in upper case, with all non-ASCII-alphanumeric characters replaced by `_`. If the value is empty or not set, the value of the environment variable COBRA_<SUFFIX

(cmd *Command, suffix string)

// If the value is empty or not set, the value of the environment variable
// COBRA_<SUFFIX> is returned instead.
func getEnvConfig(cmd *Command, suffix string) string {
	v := os.Getenv(configEnvVar(cmd.Root().Name(), suffix))
	if v == "" {
		v = os.Getenv(configEnvVar(configEnvVarGlobalPrefix, suffix))
	}
	return v
