MarkdownView for Xamarin.Forms

A native Xamarin.Forms Markdown renderer.

Gallery

Introduction

Compared to a majority of solutions, MarkdownView will render every component as a native Xamarin.Forms view instead of via an HTML backend. The Markdown is directly translated from a syntax tree to a hierarchy of Xamarin.Forms views, : no HTML is being produced at all (hurray)!

This will produce a more reactive user interface, at the cost of rendering functionalities (at the moment though!).

Install

Available on NuGet.

Quickstart

var view = new MarkdownView();
view.Markdown = "# Hello world\n\nThis is my first native markdown rendering";
view.Theme = new DarkMarkdownTheme(); // Default is white, you also modify various values
this.Content = view;

Limitations

Unfortunately, Xamarin.Forms string rendering has some limitations ...

• Inlined images aren't supported (Xamarin.Forms formatted strings doesn't support inlined views) : They will be displayed after the block they are referenced from.
• Links are only clickable at a leaf block level (Xamarin.Forms formatted strings doesn't support span user interactions) : if a leaf block contains more than one link, the user is prompted. This is almost a feature since text may be too small to be enough precise! ;)
• SVG rendering is very limited (The SVG rendering is based on SkiaSharp which doesn't seem to manage well all svg renderings)

Roadmap

• Customization _ [X] Styles _ [X] Themes
• Leaf blocks _ [X] Headings _ [X] Paragraphs _ [ ] HTML Blocks (maybe partial and specific support) _ [ ] Link reference definitions _ [X] Code blocks _ [X] Thematic breaks Container blocks _ [X] Block quote _ [X] Lists _ [ ] Numbers bullet formats _ [ ] Custom bullets
• Inlines _ [X] Textual content _ [X] Emphasis and string emphasis _ [X] Code spans _ [X] Links (partial, no interaction) _ [X] Image blocks (partial, not inlined) _ [X] SVG Rendering (Skia) Extensions _ [ ] Table blocks _ [ ] Emojis (ascii) * [ ] Task lists

Thanks

• lunet-io/markdig : used for Markdown parsing
• mono/SkiaSharp : used for SVG rendering
