Config

Package config provides convenient access methods to configuration stored as JSON or YAML.

This is a fork of the original version. This version extends the functionality of the original without losing compatibility. Major features added:

Set(path string, value interface{}) error method
Env() *config.Config method, for OS environment variables parsing
Flag() *config.Config method, for command line arguments parsing usign pkg/flag singleton
Args(args ...string) *config.Config method, for command line arguments parsing
U* methods
Copy(...path) (*config.config, error) method
Extend(*config.Config) (*config.Config, error) method
Error() error method to show last parsing error, works only with .Args() method
