Terminal colors using Swift 5’s string interpolation extensions.
import Chalk // @mxcl ~> 0.3
let colorString = "blue"
print("Here’s \(colorString, color: .blue)!")// 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")
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.
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 🙏🏻
If you have swift-sh:
$ swift sh <<EOF
import Foundation
import Chalk // @mxcl ~> 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:
