Markdown is everywhere and many of us are using Markdown for all sorts of different purposes. Wouldn't it be nice if you have an editor that can keep up with all of those scenarios? Markdown Monster is a Markdown editor and viewer that lets you edit Markdown with syntax highlighting and fast text entry. A collapsible, synced, live preview lets you see your output as you type. You can easily embed images, links, emojis and code as text or by using our gentle UI helpers that simplify many operations. You can also paste and drag images directly into the editor. Inline spell-checking and word counts keep your content streamlined unobtrusively.

You can export Markdown to HTML by saving to disk or by exporting text selections of Markdown generated HTML directly to the clipboard. The HTML preview can display syntax colored code snippets for most common coding languages, and it can easily be customized with HTML and CSS template to match your own sites and preferences. You can choose from a number of editor and preview themes and you can even use Vim or EMacs type conventions. Both the editor and preview can be customized with themes that are extensible with Web technologies. Other convenience features let you browse for and select files using the built-in folder browser, jump to the current folder in Explorer or the Terminal, print the current document's HTML output, and more.

Weblog Publishing
Markdown Monster can also publish your Markdown directly to your Weblog. If your Weblog supports WordPress, MetaWeblog or Medium APIs you can publish your documents with one click. You can also edit and republish, or download existing posts and even convert existing posts from HTML to Markdown.

Extensible via .NET Addins
In addition to building an attractive and highly functional Markdown editor, we also wanted to make sure the editor is highly extensible, so you can plug in custom features of your own. Markdown Monster includes an easy addin model that makes it easy to build extensions that let you hook into the UI, the editor behavior and the publishing process. We also provide some useful .NET Scripting and Text Templating addins that let you automate many tasks without creating a full addin. We use this same add-in API to build some of Markdown Monster's internal features so the sky's the limit. Find out more about creating an addin with .NET.

New Markdown Monster CLI
    Added new mmCLI.exe executable that automates a number of Markdown tasks. You can convert Markdown to HTML in several ways, import HTML into Markdown (with some limitations), convert markdown to PDF as well as perform a number miscellaneous operations. This replaces some of the original Markdown Monster command line switches, but the old executable retains some of the original switches that pertain to administrative tasks like registration, launching etc.

    New MarkdownToHtml, MarkdownToPdf and HtmlToMarkdown Command Line Commands
    As part of the new separated command line tool the command line now supports converting documents between Markdown and HTML and PDF as well as converting documents from HTML to Markdown. Uses mmcli.exe.

    Additional Site Relative Root Path / Overrides
    Added additional site overrides for root / path resolution in the previewer. The new additions look up the folder hierarchy for a .markdownmonster, _toc.json or docfx.json file, or any <yourProject>.mdproj file. These overrides happen after the existing checks for YAML previewWebRootPath header, and the PreviewWebRootPath in an open project file.

    Close Tabs To Right
    Added option to the Tab Context and Window Menu to close tabs to the right of the currently active tab.

    Folder Browser Drag and Drop Improvements
    You can now drag and drop files from the folder browser into external applications using the standard Windows file dragging protocol. You can also drag open document tabs as files into other applications using the same mechanims. Files dragged from the folder browser into the editor surface either open the document, or embed an image as relative links or ask to save for external paths.

    Remember PDF Export Settings
    The PDF export window now remembers its settings so the next time the window is opened the existing settings are preserved.

    Additional Paper Size Options for PDF Output
    Added additional paper sizes for PDF output: Letter, Legal, A4, B3.

    Remember common settings in Link Dialog
    The link dialog now remembers the last folder used to select a file, for the 'Open in New Window' and 'Use Link References' and checkboxes. These values are stored in the configuration and saved across shutdowns.

    Download and Embed Web Image Link as Local File
    New context menu option for image links in the editor allows to convert a Web image URL into a local image by downloading and saving the file to the local disk and re-linking the new relative (if possible) path.

    Text only Link and Image Embedding
    Added additional hotkeys to add links (ctrl-shift-k) and images (alt-shift-i) using text only insertion. Select text and the link/image is wrapped around the text with the cursor inside of the link brackets (similar to the way Github does this).

    Change h1..h6 Header Insertion Behavior
    Header insertions for h1..h6 now prefix the current string with the header prefix instead of just prefixing the current selection. It also strips off existing headers so you can change a header value to a new header type.

    Don't allow usage of non-fixed Width Fonts
    Changed behavior of Editor Font assignment so that only fixed-width fonts are allowed. The editor used in MM doesn't support propportional fonts, so a fixed-width font has to be used in order for the editor to track correctly. Also updated the description for the Options setting window.

    Show Linefeed Mode in Statusbar
    The statusbar now shows the active Linefeed mode. You can click on the mode and jump to setting the global setting to edit in the visual Settings Editor.

    Statusbar re-arrangements
    Move around some of the toolbar status items by grouping like items together and making common things a more visible. Also added additional tooltips to those items that didn't have them.

    Fix up Copy to Clipboard with CR/LF
    Fix up Ctrl-C copy behavior for text to force CR/LF to the clipboard even if the editor is running LF only mode. This fixes issues for editors that don't support LF only and paste single lines of text.

    Color Emoji Fonts in Preview Themes
    Added specific emoji fonts for the preview themes so emojis now show in color instead of the default black and white.

    Initial Support for RTL Text (experimental)
    There is initial support for paragraph based RTL editing by setting the Enable Right To Left Editor Setting, and using Alt-Shift-R and Alt-Shift-L to toggle between RTL and LTR modes respectively. This is still rough and under consideration but if you want to play with this please check out this issue on Github.

    Update Registration File Storage for better Shared Drive Operation
    Modify storage location of Registered.key to be stored in the install folder if permissions allow with a backup in the common folder. Install folder storage gives each machine accessing a potentially shared configuration its own machine specific registration file which fixes an issue where shared configurations using DropBox, OneDrive etc. would override the machine specific registration files, resulting in installations as showing not registered.

    Improved DocFx Handling in Default Markdown Parser
    Enhanced support for [!include] and [!lang-javascript] syntax to support the recently added PreviewWebRootPath sniffing, so paths to / and ~/ can be resolved. Also improved display of Info/Warning/Note etc.

    Preview: Added dedicated DocFx Markdown Parser
    Added the official DocFx parser as a markdown parser you can use to render documents. You can now pick that parser (which also uses Markdig as MM) to render DocFx documents. Rendering features for DocFx features are still limited and there are also problems with this parser. Adding for preliminary experimentation with DocFx content. Feedback welcome.

    Markdown Rendering Error Display
    Markdown rendering errors will now display an error page, rather than displaying either a blank page or not clearing the previous page. The error page shows the active Markdown Parser and a detailed code trace for potential debugging.

    Improve Windows Placement on Application Startup
    MM now will check if MM is rendering off screen when starting up. It's possible to get MM to start in 'negative' space if you size down from a large 4k display to a 1080p display for example, and MM will move the window into the viewable ViewPort area if it's hidden or even partially offscreen.

    Snippets Addin Window Placement
    The Snippets addin now by default remembers its last window position and ensures that - like the main form - it's visible on the desktop. Initial startup will launch centered in the main app window.

    Addins: Support for Colors in the MM Console
    The new Markdown Monster Console that was recently added for addin developers, now implements coloring of console output. The parameters were there previously but didn't do anything.

    Fix: Save Dialog on Shutdown on wrong Screen
    Fix issue where the Save dialog with changed content will pop up on the wrong monitor during shutdown by forcing the owner before the main window gets released.

    Fix: Open from URL
    Fixed timing issue with Open From URL that caused open operation to not show a document. Fixed with new EditorDocument.TabLoadingCompleted event also available to addins to manipulate the document after startup.

    Fix: UseMathematics and AllowMarkdownScriptTags
    Add additional notes to the Configuration for UseMathematics and MermaidDiagrams that point out that script execution has to be enabled in order to work.

    Fix: Empty Context Menu on Various Window Controls
    Fixed bug related to an empty context menu popping up on right clicking in various areas of the main form.

Only for V.I.P
