Boa implements Cobra's help and usage functions to provided an interactive user experience by leveraging Bubbletea. User's no longer need to spend time running multiple help commands to see how nested sub commands work!
Use go get to install the latest version of the library.
go get -u github.com/elewis787/boa@latest
Next, include Boa in your application:
import "github.com/elewis787/boa"
Using Boa is very simple. Below is an example on how to set the help/usage functions on a root command defined using Cobra.
rootCmd := &cobra.Command{
Version: "v0.0.1",
Use: "Example",
Long: "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.",
Short: "example command",
Example: "example [sub command]",
RunE: func(cmd *cobra.Command, args []string) error {
return nil
},
}
rootCmd.SetUsageFunc(boa.UsageFunc)
rootCmd.SetHelpFunc(boa.HelpFunc)
The key lines are:
rootCmd.SetUsageFunc(boa.UsageFunc)
rootCmd.SetHelpFunc(boa.HelpFunc)
To futher customize the look and feel of boa, you can optional set additional styles or extend the defaults
styles := boa.DefaultStyles()
styles.Title.BorderForeground(lipgloss.AdaptiveColor{Light: `#E3BD2D`, Dark: `#E3BD2D`})
styles.Border.BorderForeground(lipgloss.AdaptiveColor{Light: `#E3BD2D`, Dark: `#E3BD2D`})
styles.SelectedItem.Foreground(lipgloss.AdaptiveColor{Light: `#353C3B`, Dark: `#353C3B`}).
Background(lipgloss.AdaptiveColor{Light: `#E3BD2D`, Dark: `#E3BD2D`})
b := boa.New(boa.WithStyles(styles))
rootCmd.SetUsageFunc(b.UsageFunc)
rootCmd.SetHelpFunc(b.HelpFunc)
Use the documentation to see a full list of styles as well as other available options that can be set.
Eval how styles are exported. Goal is to make it easy to customize the layout without needing to build a cmd parser for cobraAdd back button- Option to execute sub command
