Because who doesn't need more snakes?

What is Mamba?

Mamba is a utility designed to make working with the combination of cobra and viper require less boilerplate setup.

Quick start

1. Install Mamba

go get github.com/scottkgregory/mamba

1. Annotation your config struct using the config tag in the form config:"default, description, persistent, shorthand". Arrays, slices, and maps allow for setting default values via json. Any of these values can be omitted.

type Config struct {
	Root   string   `config:"defaultRoot,The root directory to do a thing with"`
	Number int      `config:"12,A number to use for a thing"`
	Snakes []string `config:"[\"adder\"],A list of snakes. Hsssss!"`
}

3. Call Mamba in the init of your Cobra command

  mamba.Bind(Config{}, rootCmd)

4. Run your program with the --help flag to view your bound flags

5. Go forth and use your config! From this point on your config values will all be available via Viper

Examples

• basic-cli

Configuration

Options can be supplied to mamba.Bind to modify the way in which Mamba operates.

mamba.Bind(AppConfig{}, rootCmd, &mamba.Options{ Persistent: true })
