Markup

Swift 5.1 Platforms Swift Package Manager Carthage Compatible CocoaPods Twitter: @gonzalezreal

Markup generates attributed strings using a familiar markup syntax:

  • To emphasize words or sentences, you can surround the text with *asterisks* to create bold text or _underscores_ for italic text.
  • To show corrections in the text, surround the text with ~tildes~ to strike out the text.
  • You can combine formatting options.

For example, the following text:

The *quick*, ~red~ brown fox jumps over a _*lazy dog*_.

will be formatted like this:

The quick, ~red~ brown fox jumps over a lazy dog.

Just to give you an idea, here is a screenshot of the sample application displaying the markup text and the resulting attributed string:

Examples

Render an attributed string

You can use MarkupRenderer to generate an attributed string from a given markup text:

import Markup

let renderer = MarkupRenderer(baseFont: .systemFont(ofSize: 16))
let attributedText = renderer.render(text: "The *quick*, ~red~ brown fox jumps over a _*lazy dog*_.")

Access the markup syntax tree

Use MarkupParser to generate an abstract syntax tree for a markup text:

let nodes = MarkupParser.parse(text: "The *quick*, ~red~ brown fox jumps over a _*lazy dog*_")
dump(nodes)

// Outputs:
[
  .text("The "),
  .strong([
    .text("quick")
  ]),
  .text(", "),
  .delete([
    .text("red")
  ]),
  .text(" brown fox jumps over a "),
  .emphasis([
    .strong([
       .text("lazy dog")
    ])
  ])
]

Performance

Both the parsing and the rendering will take linear time to complete.

This post explains how Markup internally works, in case you are curious about the implementation.
