Markdown Monster Licensing

Source code no longer available here

Due to rampant license abuse and misuse of the source code by a few bad actors, this repository no longer holds any of Markdown Monster's source code. The source code has moved to a private repository and access is available by request.

This repository serves as the GitHub information page for downloads and features, as well as for feedback on bug reports and enhancement requests in the Issues section. For more general questions, you an also use our support message board in the Markdown Monster section.

Overview

Here's what Markdown Monster looks like using the default Dark Theme:

and here is the Light Theme:

Note that you can individually customize the theming for the editor, the preview and even the code snippet display in the previewer.

Productive

Markdown Monster has a lot of features, but we work hard to keep those features out of your way when you don't need them. If you just want to write, MM provides a minimal editing experience that provides pleasant white space around your content and an optional distraction free mode. But if you want to be more productive use shortcuts and helpers to enhance your editing experience, we help you with many useful tools to enhance your editing experience with thoughtful productivity features. Most commands have keyboard shortcuts and can be accomplished with one or two keystrokes.

Easily embed things like images, links, tables, code snippets and more with a couple of keystrokes and smart link fix ups. Because images are such a big part of content creation, our image embedding support is especially rich and supports pasting images from the clipboard, embedding with the image file/url dialog, drag and drop from explorer or a browser, and even a built-in image capture utility.

Customizable

Markdown Monster is highly customizable with themes for the main shell, editor and preview displays. The editor and preview themes can be easily customized using HTML and CSS based templates so you can make Markdown Monster your own. There are also many options to customize the editor's fonts, sizes and many display options.

You can also run in distraction free mode, that removes toolbars, menus, preview, sidebar and other distractions to let you focus on your code. Or use Presentation mode to focus on reading content without the editor view.

Extensible

Markdown Monster is extensible with .NET code. You can use our Snippets or Commander addins to create custom text expansions, or automate common tasks using .NET Code snippets. A full addin extensibility model allows deep integration with most of Markdown Monster's features and UI to create sophisticated extensions using a straightforward Addin model. There is an Addin Manager that lets you easily install, update and manage available Addins.

Weblog Publishing

If you have a blog chances are you can use Markdown Monster to create your content and publish it to your blogging service. Markdown Monster can publish to many common Weblog engines including WordPress, Medium and any service that use MetaWeblog API. MM automatically handles converting your Markdown content to HTML, fixing up links and publishing and re-publishing your Markdown content cleanly to blogging services.

The New Weblog Post feature automatically sets up a post folder in a Weblog Posts directory hierarchy to let you organize posts in a shared DropBox or OneDrive (if available) folder so you can easily work on posts from multiple machines.

Markdown Monster's integrated Git features also work great for any Git based service like Jekyll, Ghost, Hugo or Wyam to write your posts locally and immediately push them to your remote Git repository to publish. Git integration is built into MM to commit your changes either individually or in batch or you can open your favorite Git Client to publish your changes to your hosted content blog.

Why another Markdown Editor?

Markdown is everywhere these days, and it's becoming a favorite format for many developers, writers and documentation experts to create lots of different kinds of content in this format. Markdown is used in a lot of different places:

• Source Code documentation files (like this one)
• Weblog posts
• Product documentation
• Message Board message entry
• Application text entry for formatted text

Personally I use Markdown for my Weblog, my message board, of course on GitHub and in a number of applications that have free form text fields that allow for formatted text - for example in our Webstore product descriptions are in Markdown.

Having a dedicated Markdown Editor that gets out of your way, yet provides a few helpful features and lets you add custom features that make your content creation sessions more productive is important. Check out this post on why it makes sense to use a dedicated Markdown Editor rather than a generic text editor for Markdown document creation. The ability to easily publish your Markdown to any MetaWebLog or Wordpress API endpoint is also useful as it allows you to easily publish to blogs or any application that supports for either for these formats.

Markdown Monster wants to eat your Markdown!

Markdown Monster is a Markdown editor and Viewer for Windows that lets you create edit or simply preview Markdown text. It provides basic editing functionality with a few nice usability features for quickly embedding images, links, code, tables, screen shots and other markup. You get a responsive text editor that's got you covered with Markdown syntax highlighting, a collapsible live preview, so you can see what your output looks like, inline spellchecking and a handful of optimized menu options that help you mark up your text and embed and link content into your Markdown document. Additionally utility features let you quickly jump to the command line or an Explorer window, commit a document to Git, or even edit images in your favorite image editor.

Table Editor

Markdown Monster includes a powerful two-way table editor that lets you interactively edit content in tables. You can use the rich table editor to enter your Table content, and re-open Markdown table code in the editor for later editing and re-formatting.

Folder Browser

Markdown editing often requires managing related content like images, or multiple files for links etc. and Markdown Monster provides a folder browser to see and navigate files while in the editor. The browser has built-in Git status support so you can immediately see what documents have changed in your folder tree and you can easily review and undo changes. The browser lets you navigate folders, create, delete and move files and there are many options to view, open and edit files.

The folder browser also supports searching, moving and renaming of files as you would expect of a file browser.

Document Outline

When working with long documents it's important to have an easy way to navigate the document's structure quickly, and the Document Outline makes it easy to see the document's structure at a glance and jump to any section quickly. The outline also lets you pick up document Ids for quickly embedding same-document links.

Git Integration

These days working with Markdown often means working with Git repositories and Markdown Monster integrates common Git tasks that you need to perform during editing. You can easily review, commit and push changes, as well as cloning and creating of new repositories.

Screen Captures

The Screen Capture addin supports two separate capture modes:

• Techsmith's popular and versatile SnagIt Screen Capture Tool
• Built-in Screen Capture Addin

To capture, simply click the capture button (camera icon) and the main app minimizes and either SnagIt or the integrated capture tool pops up to let you select the object to capture. With SnagIt you can use most of SnagIt's native capture modes, for the built-in tool you can select Windows and Controls on the screen. Captures are previewed and have options for editing, and when finished the captured image is embedded and linked directly into the Markdown content.

Here's the SnagIt Screen Capture in action:

And here is the self-contained, built-in Screen Capture Module:

Template Expansions

The built-in Snippets addin allows you to create templates - including dynamic templates using C# code - to expand text either on a typed expansion keyword, via interactive selection or via a pre-defined shortcut key.

Weblog Publishing

A common use case for Markdown is to create rich blog posts with embedded links and content and Markdown Monster makes it easy to pull together content from various sources. You can easily embed images by pasting from the the clipboard, or by linking images from URLs or files or using the built-in Screen Capture addin or SnagIt support.

Writing long blog posts and articles, and coordinating lots of related content is one of the main reasons I built this tool in the first place as is publishing and updating content easily to various types of blogs and content generators.

You can take any Markdown and turn it into a blog post by using the Weblog publishing feature. If you use WordPress, a MetaWeblog API Blog, Medium or Jekyll, you can click the Weblog button on the toolbar and set up your blog (MetaWebLog, WordPress or Medium), and then specify the Weblog specifics like title, abstract, tags and Web Site to publish to. Posts can be easily published and also re-published with the click of a button. You can also download existing blog posts from your blog and edit them as Markdown and then republish them.

Customizable

Most editing and UI features in Markdown Monster are optional and can be turned on and off. Want to work distraction free and see no preview or spell checking hints? You can turn them off. Want to store configuration data in a shared cloud folder? You can do that too.

Want a different editor theme than the dark default or a preview theme that matches your blog or branding? You can easily switch to one of the many built-in editor themes. For previews you can use either one of several built-in themes or add your own with a simple, plain HTML/CSS template. You can even create themes that link to your own online styles.

The editor and previewer are HTML and JavaScript based, so you can also apply any custom styling and even hook up custom JavaScript code if you want to get fancy beyond the basic configuration. The preview themes are easy to modify as they are simply HTML and CSS templates.

Extensible with .NET Add-ins

One of the key feature and the main reason I built Markdown Monster is that it is extensible, so that you and I can plug additional functionality into it without bloating the main product.

You can find available public Addins you can install in the Markdown Monster Addin Manager from the Tools menu:

There is a variety of functionality available in addins. Here are a few examples:

Right now the registry is pretty sparse, but here are a few Addins you can check out:

• Console
  Lets you pin an always-active Terminal Console window to the bottom of Markdown Monster.

• Commander C# Scripting
  A C# based scripting addin that lets you automate tasks using script code. For simple tasks this is quicker and easier than creating a full addin.

• Save Image to Azure Blob Storage
  Lets you save images as Azure Blob storage items and embeds a link to the an uploaded resoure into your Markdown.

• Gist
  This addin allows you to Open from Gist and Save as Gist as well as letting you create code snippets and embed them as Gists into your Markdown content.

• Pandoc Markdown Parser
  This addin provides a PanDoc Markdown processor that can be used instead of the default MarkDig parser. This addin also provides a host of document conversion options to convert your Markdown to PDF, DOC, EPub and a few other formats using an interactive dialog.

.NET Based Extensibility

Markdown Monster Addins have access to an add-in model that lets you manipulate and automate any open documents and the editor, lets you load new documents, launch external processes, add menu options and other UI features, open a new sidebar, generally interact with the entire UI and attach to life cycle events to get notifications of various application events like documents opening and closing, documents being saved and the application shutting down, etc...

Complexity of Addins can vary greatly from very simple automation tools like the Console Addin that simply pins a Terminal window to Markdown Monster, or something as complex as the KavaDocs addin that manages an entire documentation application with many custom windows and sidebars that are integrated into Markdown Monster.

Addins have access to most features of Markdown Monster and they are fairly easy to create. We as well as several third parties have created a number of useful addins using the powerful addin model and I encourage you to browse addins to see what you can do.

Creating Addins

One of the key features of Markdown Monster is that you can also create your own addins using the .NET based Markdown Monster Addin model. It's very easy to create new addins and we provide a Visual Studio Project Template Extension to facilitate the process of getting started with creating an Addin. All of our plug-ins are also available on GitHub, so you can easily check out how other addins were created.

You can find documentation for creating Addins here:

• Creating a Markdown Monster Addin
• Markdown Monster Addin Visual Studio Project Template
• Accessing and Manipulating the Active Editor
• Bringing up UI from your Addin

Markdown Monster Addin Registry

You can create addins for your own use, simply by copying them into the %appdata%\Addins folder, or if you created an Addin that you think might be useful for others you can publish on the Markdown Monster Addin Registry. The registry holds public Addins that show in the Addin Manager inside of Markdown Monster:

You can find out more on how to publish your Addins in this GitHub repository:

• Markdown Monster Addin Registry

Other Add-ins - What do you want to build?

I can think of a few add-in ideas - a quick way to commit to Git and Push would be useful for documentation solutions, or Git based blogs, so you can easily persist changes to a GitHub repository. Embedding all sorts of content like reference links, AdSense links, Amazon product links, a new post template engine, etc., etc.

Or maybe you have custom applications that use Markdown text and provide an API that allows you to post the Markdown (or HTML) to the server. It's easy to build a custom add-in that lets you take either the Markdown text or rendered HTML and push it to a custom REST interface in your custom application.

Acknowledgements

This application heavily leans several third party libraries without which this tool would not have been possible. Many thanks for the producers of these libraries that are used extensively in Markdown Monster:

• Ace Editor
  Ace Editor is a power HTML based editor platform that makes it easy to plug syntax highlighted software style editing possible in a browser. Markdown Monster uses Ace Editor for the main Markdown editing experience inside of a Web browser control that interacts with the WPF application.

• MarkDig Markdown Parser
  This extensible Markdown parser library is used for the rendering Markdown to HTML in Markdown Monster. The library is fast and supports a number of useful extensions like GitHub Flavored Markdown, table support, auto-linking and various add-on protocols. The feature set is extensible via a plug-in pipeline.

• MahApps.Metro
  This library provides the Metro style window and theming support of the top level application shell. It's an easy to use library that makes it a snap to build nice looking WPF applications.

• Dragablz
  This library provides the tab control support for the editor allowing for nicely styled tab reordering and overflow. The library also supports tab tear off tabs and layout docking although this feature is not used in Markdown Monster.

• nHunspell Spell Checking
  Spell checking is handled via the hunspell library and the .NET wrapper in nhunspell. This library checks for mispellings and provides lookups for misspelled words. Word parsing is done in JavaScript and the spell checking is done in .NET by piping word lists to .NET to check which is drastically faster than doing the spell checking in the browser using JavaScript.

Additional shout outs to these libraries used:

• HtmlAgility Pack
• LibGit2Sharp
• YamlDotnet
• Windows API Codepack
• FontAwesome.WPF
• ReverseMarkdown
