Most markdown users would agree that standard markdown has limitations for efficient editing and proofreading.
By integrating the right markdown extensions into your workflow, you can dramatically improve how you create, review, and publish markdown documents.
In this post, we'll explore popular markdown extensions for advanced tables, typography, previews, and more. We'll see how to add extensions in Visual Studio Code, GitHub, and other platforms. And we'll review best practices to select and test extensions that enhance productivity.
Markdown is a lightweight markup language that allows users to write content using simple syntax that can easily be converted to HTML. It was created to be easy to read, write, and understand - making it popular for documentation, readme files, blog posts, and more.
However, standard Markdown lacks some additional formatting options that can enhance documents and streamline workflows. This is where Markdown extensions come in.
Markdown uses simple plaintext formatting like headers, lists, links, and code blocks that can be written in any text editor. Some key elements include:
Markdown Toolbox
# symbols[text](URL)This makes Markdown a fast, minimal syntax focused on readability and conversion to HTML.
While Markdown covers all the basics, there are some restrictions around:
Additional useful features like footnotes, abbreviations, and data visualization are also missing.
Markdown extensions are plugins that extend the capabilities of standard Markdown by adding new syntax and functionality.
Some common additions include:
They power up Markdown for more robust documents.
Key reasons to utilize Markdown extensions include:
Overall, extensions make Markdown more versatile and optimal for technical writing.
The Markdown language and its .md file extension were created in 2004 by John Gruber and Aaron Swartz. They wanted to develop a simpler way of writing in plain text format without heavy formatting instructions and tags.
Markdown files use the .md file extension to indicate the Markdown formatting syntax. When opening a .md file, Markdown-compatible apps and editors will recognize the Markdown formatting and render it properly.
Some key benefits of using .md files for Markdown include:
.md files are lightweight plain text files that can be opened on any device or operating system. You're not locked into proprietary file types..md files work seamlessly with version control systems like Git, allowing seamless tracking of changes..md files have longevity and will remain readable in the future.In summary, the .md file extension is integral to how Markdown functions. It signals to apps and editors that the file should be rendered with Markdown formatting. The .md extension made Markdown the popular lightweight markup language it is today.
Markdown extensions allow developers to customize and enhance the Markdown editing experience in Visual Studio Code. Some key capabilities provided by Markdown extensions include:
Extensions can provide syntax highlighting for custom Markdown syntax like tables, strikethrough text, task lists, and more. This makes editing Markdown more visually appealing and errors easier to spot.
Popular extensions like Markdown All in One and Markdown Preview Enhanced offer robust syntax support for Markdown flavors like CommonMark and GitHub Flavored Markdown.
Markdown preview extensions give you a live rendered HTML preview of your Markdown document right inside your editor.
As you type, the preview updates in real-time, allowing you to visually check formatting changes on the fly without having to export the file.
Extensions provide extra tools for managing Markdown documents, like file outline views, word counts, and format converters to go between Markdown, HTML, and PDF.
Some extensions enable exporting Markdown directly to sites like WordPress or Medium with a click.
So in summary, Markdown extensions supercharge VS Code into a full-featured Markdown editor, helping increase productivity for writers and developers authoring Markdown content. They add vital capabilities like syntax support, previews, and content publishing that VS Code lacks out-of-the-box.
VS Code has excellent built-in support for working with Markdown files. When you create or open a file in VS Code with the .md file extension, it will automatically switch to Markdown preview mode.
Some key things to know about working with Markdown files in VS Code:
.md file extension lets VS Code know it should render the file using Markdown formatting.So in summary, the .md file extension is what signals to VS Code that it's dealing with a Markdown document. This allows it to enable Markdown rendering when viewing the file, make the editor Markdown-aware, and optimize the experience for working with Markdown content. The seamless editing to preview workflow makes VS Code a very popular choice for writing Markdown among developers and writers.
Writing a Markdown file is easy with just a text editor. Here are the steps:
Open any plain text editor like Notepad, TextEdit, or Visual Studio Code.
Create a new file and save it with the .md file extension. For example, readme.md. The .md extension tells your operating system this is a Markdown formatted file.
Start writing your content using Markdown syntax. Some examples:
# Heading 1 for top level headings## Heading 2 for second level headings*italics* and **bold** for text formatting- Lists for bullet points[Links](https://example.com) for adding linksSave the .md file and open it in a Markdown previewer to see the formatted output. Many text editors like Visual Studio Code have built-in Markdown preview.
Use Markdown extensions like tables, emojis, strikethrough text, and more to add additional formatting.
That's the basics! With those steps, you can create Markdown-formatted files for blogs, documentation, READMEs on GitHub, and more. Let me know if you have any other questions!
Markdown extensions provide additional functionality and features beyond standard Markdown syntax. They make creating, editing, and formatting Markdown documents easier and more powerful. Here are some of the most useful Markdown extensions:
Table creation in standard Markdown can be tedious, requiring the use of pipes and dashes to format the rows and columns. Extensions like Markdown Tables Generator simplify the process with an intuitive interface for building Markdown tables.
Other handy table extensions include:
These extensions save significant time when producing complex Markdown tables and diagrams.
Basic Markdown lacks advanced typographic formatting like:
Extensions provide these capabilities, allowing for richer text formatting:
With typographic extensions, Markdown documents can incorporate text formatting on par with word processors.
Emojis liven up Markdown content. Extensions like markdown-emoji and resources like Emojipedia make adding emojis simple:
:smile:) to images.These tools take the guesswork out of using emojis in Markdown.
Live previews help visualize how Markdown formatting will render. Extensions like Markdown Preview GitHub Styling emulate sites' specific Markdown implementations:
Preview extensions enable direct on-screen visualization of Markdown as it will appear when published.
Visual Studio Code has a vibrant ecosystem of extensions that can enhance the markdown editing experience. Here are some useful markdown extensions to install:
User Defined Snippets - This allows you to create your own snippet shortcuts for commonly used markdown syntax. For example, you could set up a shortcut to auto-generate a markdown table structure.
IntelliSense - This provides intelligent autocomplete suggestions as you type to speed up markdown formatting. For example, it can automatically suggest matching markdown syntax when typing headings, links, images, etc.
To install extensions in VS Code:
Ctrl+Shift+XUsing extensions like these can save considerable time when authoring markdown documents.
MkDocs is a popular static site generator geared towards project documentation. There are several markdown extensions that can be integrated with MkDocs to improve the documentation editing workflow:
markdown-include - Allows you to modularize documentation by including external markdown files. This is useful for reusing content snippets across multiple files.
pymdown-extensions - This is a collection of extensions that add enhanced formatting like tables, emojis, tasklists and more.
To add extensions in MkDocs:
mkdocs.ymlmarkdown_extensions section add the extensions you want to use. For example:markdown_extensions:
- markdown_include.include:
base_path: docs
- pymdownx.emoji:
emoji_index: !!python/name:materialx.emoji.twemoji
emoji_generator: !!python/name:materialx.emoji.to_svg
Proper use of extensions can make docs more visually appealing and improve navigation.
GitHub has integrated several useful markdown extensions called GitHub Flavored Markdown (GFM):
Multiple task lists - These make it easy to track issues and pull requests right within markdown.
Strikethrough - Allows crossing out text with ~~double tilde~~ formatting.
Emoji support - GitHub uses Emojipedia so you can add emojis via :shortcodes:.
Other extensions like markdown tables and syntax highlighting are also supported.
To enable GFM in a GitHub repo:
This will allow contributors to leverage GFM extensions when editing markdown files, improving collaboration.
Developing custom Markdown extensions allows users to tailor Markdown functionality for their specific needs. As Markdown has grown in popularity, the ability to customize it has become increasingly important. Custom extensions provide flexibility to enhance Markdown in ways that work best for individual users and workflows.
There are several key reasons why users might want to create custom Markdown extensions:
Add missing features: Standard Markdown lacks some formatting features like tables or syntax highlighting. Custom extensions can add this missing functionality.
Optimize for specific use cases: Users may want custom features optimized for documentation, note-taking, technical writing, etc. Extensions allow Markdown optimization for these specialized use cases.
Integrate with other tools: Developers can create extensions to integrate Markdown with other platforms like CMSs, wikis, IDEs, etc. This allows leveraging Markdown everywhere.
Control over functionality: Custom extensions give users more control vs relying on pre-built extensions that may not meet all needs.
Fix rendering inconsistencies: Since Markdown lacks a formal spec, rendering can vary across platforms. Custom extensions can enforce consistent rendering.
Popular frameworks for developing Markdown extensions include:
markdown-it: Node.js library that serves as a Markdown parser and compiler. Easy to extend with plugins.
CommonMark: Strongly defined Markdown specification that serves as a useful framework for extensions.
GitHub Flavored Markdown (GFM): Markdown dialect optimized for GitHub built on top of CommonMark. Useful baseline for extensions.
All these frameworks allow JavaScript/Node.js based extension development. Most extensions are written as pluggable modules that extend a Markdown parser like markdown-it.
Key resources for developers creating custom Markdown extensions include:
markdown-it Documentation: Developer guides, API docs, examples, and information on writing plugins.
CommonMark Spec: Formal specification for compliant parsers and extensions.
GitHub Markdown Spec: GFM spec built on CommonMark for GitHub-flavored extensions.
StackOverflow: Developer community for asking Markdown extension questions.
Awesome Markdown: Curated list of Markdown tools and resources for developers.
With robust frameworks and specifications now available, developers have great flexibility in rolling their own custom Markdown extensions tailored to user needs.
When choosing markdown extensions, it's important to carefully evaluate your needs and workflow to determine which ones will provide the most value without unnecessary complexity. Start by taking stock of where you currently experience friction or inefficiency when working with markdown - are there repetitive tasks you need to streamline? Formatting issues that create bottlenecks? Integrations with other tools that could be smoother? Make a list of these pain points to guide your search.
Next, browse repositories like those on GitHub to find extensions that specifically address your list. Avoid the temptation to add extensions that offer neat capabilities but don't directly map to an established need - too many niche extensions can bog down your system and editor. Carefully read documentation to ensure any extensions you're considering are actively maintained and compatible with the markdown flavor you use.
Before settling on a markdown extension, always verify compatibility to avoid headaches down the road. For example, some extensions follow the basic CommonMark specification while others support extended syntax like tables and strikethrough text in Markdown Extra or GitHub Flavored Markdown. Make sure the extensions you choose work with the underlying markdown format you need for your intended output.
Checking compatibility also means testing extensions against the specific generators and editors you use, not just the markdown flavor itself. An extension may claim broad compatibility but still have issues in certain environments, so test rigorously before relying on it for production work. Save yourself the pain of discovering formatting quirks or broken integrations too late.
Speaking of testing, extensively try out markdown extensions before adopting them into your regular workflows. Evaluate them using your actual markdown content, not just basic test cases. Look for impacts on formatting, accuracy, editor performance, preview rendering, and exports. Check both visual presentation and the formatted markup itself. If you collaborate with others, have teammates trial the extensions as another compatibility verification.
Isolate extensions before bringing them together to identify any conflicts. Start with a simple markdown document, then gradually increase complexity to catch issues. Moving an extension from a test environment into production too soon can make problems hard to troubleshoot later. Only rely on an extension once you've confirmed solid performance with real-world documents in your target editing and publishing platforms.
The CommonMark specification aims to standardize Markdown syntax and resolve ambiguities that exist between flavors of Markdown. As it continues to gain adoption, CommonMark could become the predominant Markdown standard. This would allow for greater consistency across Markdown implementations and improved interoperability.
Looking beyond CommonMark, there may be efforts to add new features to the base Markdown spec through optional extensions. For example, support for elements like tables, strikethrough text, task lists, and more advanced formatting could become part of future Markdown standards. This would allow users to leverage these features while maintaining back-compatibility.
Markdown extensions are beginning to provide native support for interactive rich media beyond just text. For example, the mermaid extension allows Markdown documents to contain mermaid diagrams. As more rich media capabilities get introduced, Markdown may evolve into a more versatile document format.
Extensions that enable Markdown to output other formats like PDF or HTML slides are also gaining popularity. More seamless integration with multimedia is likely on the horizon as well. This includes natively embedding or linking videos, audio, vector images, and graphical data visualizations.
Markdown's simplicity lends itself well to version control and collaboration systems like Git and GitHub. As developers share Markdown-based documentation in repositories, there is increasing demand for extensions that simplify things like internal links across documents, file diffs, comment handling, and edit tracking.
Integrations with cloud-based collaborative editing platforms may also emerge to allow seamless multi-user editing, access controls, and revision histories for Markdown content. Features like suggesting changes, tagging other collaborators, or viewing edit activity could come to Markdown workflows. This would aid collaborative writing and documentation at scale.
Markdown extensions provide a range of productivity enhancements for working with Markdown files:
Overall, extensions help optimize Markdown editing, allowing writers, developers, and content creators to work more efficiently.
