Function getEnvValue

go/client.go:271–279

getEnvValue looks up a key in an environment slice ([]string of "KEY=VALUE"). Returns the value if found, or empty string otherwise.

(env []string, key string)

// getEnvValue looks up a key in an environment slice ([]string of "KEY=VALUE").
// Returns the value if found, or empty string otherwise.
func getEnvValue(env []string, key string) string {
	prefix := key + "="
	for i := len(env) - 1; i >= 0; i-- {
		if strings.HasPrefix(env[i], prefix) {
			return env[i][len(prefix):]
		}
	}
	return ""
}

// setEnvValue returns a copy of env with all existing entries for key removed and
// a single trailing KEY=VALUE entry added so SDK-managed values win deterministically.
