Markdig is a fast, powerful, CommonMark compliant, extensible Markdown processor for.NET. NOTE: The repository is under construction. There will be a dedicated website and proper documentation at some point! Markdig Extension – Bad Header Handler First off, if you haven’t seen Markdig yet, you’re missing out! It has to be the most extensible Markdown processor I’ve ever seen, and it is still incredibly fast. It’s slim enough to confidently use on small.NET Clients like Xamarin, and supports custom output as. Rendering HTML with MarkDig To convert the Markdown into HTML, I used the superb MarkDig library. This not only makes it super easy to convert basic Markdown to HTML, but supports several useful extensions. Rossibel Rojas Huama (@rossibel.markdig) en TikTok 144 me gusta. 📊 ℕ𝕖𝕘𝕠𝕔𝕚𝕠𝕤 𝕆𝕟𝕝𝕚𝕟𝕖 💎 𝔾𝕒𝕟𝕒.

Third Party Extensions
Documentation
The repository is under construction. There will be a dedicated website and proper documentation at some point!
While there is not yet a dedicated documentation, you can find from the specs documentation how to use these extensions.
In the meantime, you can have a 'behind the scene' article about Markdig in my blog post 'Implementing a Markdown Engine for .NET'
Download
Markdig Nuget
Use Markdown With ASP.NET Core - CODE Mag
Markdig is available as a NuGet package:
Also Markdig.Signed NuGet package provides signed assemblies.
Usage
The main entry point for the API is the Markdig.Markdown
class:
By default, without any options, Markdig is using the plain CommonMark parser:
In order to activate most of all advanced extensions (except Emoji, SoftLine as HardLine, Bootstrap, YAML Front Matter, JiraLinks and SmartyPants)
You can have a look at the MarkdownExtensions that describes all actionable extensions (by modifying the MarkdownPipeline)
Build
In order to build Markdig, you need to install .NET Core RTM

Benchmarking
This is an early preview of the benchmarking against various implementations:
C implementations:
- cmark (version: 0.25.0): Reference C implementation of CommonMark, no support for extensions
- Moonshine (version: : popular C Markdown processor
.NET implementations:
- Markdig (version: 0.5.x): itself
- CommonMark.NET(master) (version: 0.11.0): CommonMark implementation for .NET, no support for extensions, port of cmark
- CommonMark.NET(pipe_tables): An evolution of CommonMark.NET, supports extensions, not released yet
- MarkdownDeep (version: 1.5.0): another .NET implementation
- MarkdownSharp (version: 1.13.0): Open source C# implementation of Markdown processor, as featured on Stack Overflow, regexp based.
- Marked.NET (version: 1.0.5) port of original marked.js project
- Microsoft.DocAsCode.MarkdownLite (version: 2.0.1) used by the docfx project
JavaScript/V8 implementations:
- Strike.V8 (version: 1.5.0) marked.js running in Google V8 (not .NET based)
Markdig Table
Analysis of the results:
- Markdig is roughly x100 times faster than MarkdownSharp, 30x times faster than docfx
- Among the best in CPU, Extremely competitive and often faster than other implementations (not feature wise equivalent)
- 15% to 30% less allocations and GC pressure
Because Marked.NET, MarkdownSharp and DocAsCode.MarkdownLite are way too slow, they are not included in the following charts:
Performance for x86:
Performance for x64:

Credits
Thanks to the fantastic work done by John Mac Farlane for the CommonMark specs and all the people involved in making Markdown a better standard!
This project would not have been possible without this huge foundation.
Thanks also to the project BenchmarkDotNet that makes benchmarking so easy to setup!
Some decoding part (e.g HTML EntityHelper.cs) have been re-used from CommonMark.NET
Thanks to the work done by @clarkd on the JIRA Link extension (https://github.com/clarkd/MarkdigJiraLinker), now included with this project!
