### API

fmt package-like functions are provided.

```go

pp.Print()

pp.Println()

pp.Sprint()

pp.Fprintf()

```

See [the documentation](https://pkg.go.dev/github.com/k0kubun/pp/v3#section-documentation) for API details.

### Configuration

They can be customized globally with `pp.Default`.

```go

pp.Default.SetColoringEnabled(false)

pp.Println() // no color

```

You can also create individual instances that do not interfere with the default printer:

```go

mypp := pp.New()

mypp.SetColoringEnabled(false)

mypp.SetExportedOnly(true)

mypp.SetOmitEmpty(true)

mypp.Println()

```

See [PrettyPrinter documentation](https://pkg.go.dev/github.com/k0kubun/pp/v3#PrettyPrinter) for all available configurations.

### Custom colors

If you require, you may change the colors (all or some) for syntax highlighting:

```go

// Create a struct describing your scheme

scheme := pp.ColorScheme{

	Integer:       pp.Green | pp.Bold,

	Float:         pp.Black | pp.BackgroundWhite | pp.Bold,

	String:        pp.Yellow,

}

// Register it for usage

pp.Default.SetColorScheme(scheme)

```

Look into ColorScheme struct for the field names.

If you would like to revert to the default highlighting, you may do so by calling `pp.ResetColorScheme()`.

Out of the following color flags, you may combine any color with a background color and optionally with the bold parameter. Please note that bold will likely not work on the windows platform.

```go

// Colors

Black

Red

Green

Yellow

Blue

Magenta

Cyan

White

// Background colors

BackgroundBlack

BackgroundRed

BackgroundGreen

BackgroundYellow

BackgroundBlue

BackgroundMagenta

BackgroundCyan

BackgroundWhite

// Other

```
