# Chalk

Terminal colors using Swift 5’s string interpolation extensions.



```swift

import Chalk  // @mxcl ~> 0.3

let colorString = "blue"

print("Here’s \(colorString, color: .blue)!")

```

# Styles, Backgrounds, Extended Colors etc.

```swift

// color, background & style can be specified all together or individually:

print("Foo \(string, color: .blue) bar")

print("Foo \(string, color: .blue, background: .yellow) bar")

print("Foo \(string, color: .blue, background: .yellow, style: .underline) bar")

// styles are an `OptionSet`:

print("Foo \(string, style: .underline) bar")

print("Foo \(string, style: [.underline, .bold]) bar")

// 256 color mode is supported:

print("Foo \(string, color: .extended(78) bar")

```

# Name

[Chalk] by [@sindresorhus] is an extremely famous Node package for the same

purpose. Open source is facilitated by naming connections, we picked the same

name to enable those mental connections.

This package is called Chalk, or `mxcl/Chalk` or Chalk for Swift when

disambiguating.

# Support mxcl

Hey there, I’m Max Howell, a prolific producer of open source and probably you

already use some of it (I created [`brew`]). I work full-time on open source and

it’s hard; currently *I earn less than minimum wage*. Please help me continue my

work, I appreciate it 🙏🏻

# Demo

If you have [`swift-sh`]:

```

$ swift sh < 0.3

for x in 0..<256 {

    let cell = " \(x)".padding(toLength: 5, withPad: " ", startingAt: 0)

    let terminator = (x + 3).isMultiple(of: 6) ? "\n" : ""

    print("\(cell, color: .extended(15), background: .extended(UInt8(x)))", terminator: terminator)

}

EOF

```

Will give you:
