AttributedText is a view for displaying some HTML-tagged text using **SwiftUI Text View**.

Features

You can clone the repo and run the AttributedTextExample project to explore the AttributedText features.

These are the main points to pay attention to.

  1. You can define the tags you need or use the defaults.

You need to set the required tags and provide associated closures. Each closure must be a modifier that is applied to the SwiftUI Text View when a specific tag is encountered.

##### Override the default values, for example at application launch.

``swift @main struct ExampleApp: App { init() { AttributedText.tags = [ "b": { $0.bold() }, "i": { $0.italic() } ] } } ``

In this case only \<b\> and \<i\> tags will be processed. All other tags will be ignored or deleted.

##### Set the custom values for each instance.

```swift private let tags: Dictionary<String, (Text) -> (Text)> = [ // Set the necessary values. ]

var body: some View { AttributedText("Text", tags: tags) } ```

  1. Basic modifiers can still be applied, such as changing the font and color of the text.

Code example:

``swift AttributedText("This is <b>bold</b> and <i>italic</i> text.") .foregroundColor(.blue) .font(.title) ``

Result:

[1 feature]

  1. Handles unopened/unclosed tags.

Code example:

``swift AttributedText("This is italic</i> and <b>bold text.") ``

Result:

[2 feature]

  1. Supports overlapping tags.

Code example:

``swift AttributedText("This is <b>bold only, <i>bold and italic</b> and italic only</i> text.") ``

Result:

[3 feature]

  1. Deletes tags that have no modifiers.

Code example:

``swift AttributedText("<unknown>This is <b>bold</b> and <i>italic</i> text.</unknown>") ``

Result:

[4 feature]

  1. Does not handle HTML characters such as &amp;.

Code example:

``swift AttributedText("This is <b>bold</b> &amp; <i>italic</i> text.") ``

Result:

[5 feature]

  1. Only single-word tags are supported. Tags with more than one word or containing any characters besides letters or numbers are ignored and not removed.

Code example:

``swift AttributedText("This is <tag attribute1=\"value1\"> <b>bold</b> and <i>italic</i> text</tag>.") ``

Result:

[6 feature]
