Table of contents

• Run command 'Create Table of Contents' to insert a new table of contents.

• The TOC is automatically updated on file save by default. To disable, please change the toc.updateOnSave option.

• The indentation type (tab or spaces) of TOC can be configured per file. Find the setting in the right bottom corner of VS Code's status bar.

  Note: Be sure to also check the list.indentationSize option.

• To make TOC compatible with GitHub or GitLab, set option slugifyMode accordingly

• Three ways to control which headings are present in the TOC:

  Click to expand

  1. Add <!-- omit in toc --> at the end of a heading to ignore it in TOC
     (It can also be placed above a heading)

  2. Use toc.levels setting.

  3. You can also use the toc.omittedFromToc setting to omit some headings (and their subheadings) from TOC:

     Note:

     • Setext headings (underlined with or ---) can also be omitted, just put their # and ## versions in the setting, respectively.
     • When omitting heading, make sure headings within a document are unique. Duplicate headings may lead to unpredictable behavior.

• Easily add/update/remove section numbering

• In case you are seeing unexpected TOC recognition, you can add a <!-- no toc --> comment above the list.

List editing

Note: By default, this extension tries to determine indentation size for different lists according to CommonMark Spec. If you prefer to use a fixed tab size, please change the list.indentationSize setting.

FAQ

Q: Error 'command 'markdown.extension.onXXXKey' not found'

In most cases, it is because VSCode needs a few seconds to load this extension when you open a Markdown file for the first time. (You will see a message 'Activating Extensions...' on the status bar.)

If you still see this 'command not found' error after waiting for a long time, please try to restart VSCode (or reinstall this extension¹ if needed). Otherwise feel free to open a new issue on GitHub.

^{1. uninstall this extension, restart VSCode (important!) and then reinstall}

Q: Which Markdown syntax is supported?

• Tables, strikethrough and task lists (from GitHub Flavored Markdown)
• Math support (from KaTeX)

For other Markdown syntax, you need to install the corresponding extensions from VSCode marketplace (e.g. Mermaid diagram, emoji, footnotes and superscript). Once installed, they will take effect in VSCode and also the exported HTML file.

Q: This extension has overridden some of my key bindings (e.g. Ctrl + B, Alt + C)

You can easily manage key bindings with VSCode's 'Keyboard Shortcuts' page. (Commands provided by this extension have prefix markdown.extension.)

Q: The extension is unresponsive, causing lag etc. (performance issues)

From experience, there is a good chance that the performance issues are caused by other extensions (e.g., some spell checker extensions).

To find out the root cause, you can install our development build (debug.vsix) and create a CPU profile following this official instruction from the VS Code. And then please open a GitHub issue with that profile (.cpuprofile.txt) attached.

Changelog

See CHANGELOG for more information.

Latest Development Build

Download it here, please click the latest passing event to download artifacts. There are two versions: markdown-all-in-one-*.vsix is the regular build, while debug.vsix is used to create a verbose CPU profile.

To install, execute Extensions: Install from VSIX... in the VS Code Command Palette (ctrl + shift + p)

Markdown is a lightweight markup language for adding formatting elements to plain text. IntelliJ IDEA recognizes Markdown files, provides a dedicated editor with highlighting, completion, and formatting, and shows the rendered HTML in a live preview pane.

Create a new Markdown file

By default, IntelliJ IDEA recognizes any file with the .md or .markdown extension as a Markdown file.

1. Right-click a directory in the Project tool window Alt+1 and select New | File.

   Alternatively, you can select the necessary directory, press Alt+Insert, and then select File.

2. Enter a name for your file with a recognized extension, for example: readme.md.

The Markdown editor provides several basic formatting actions in the toolbar:

• : Bold

• : Strikethrough

• : Italic

• : Code

• : Decrease heading level

• : Increase heading level

• : Convert an inline link to a reference link

You can use the preview pane to see the rendered HTML.

There is also completion for links to files in the current project, for example, if you need to reference source code, images, or other Markdown files.

Code blocks

To insert a fenced code block, use triple backticks (```) before and after the code block. If you specify the language for the code block, by default, the Markdown editor injects the corresponding language. This enables syntax highlighting and other coding assistance features for the specified language: code completion, inspections, and intention actions.

Disable coding assistance in code blocks

If your code blocks are not meant to be syntactically correct, you may want to disable code injection and syntax errors in code blocks.

1. In the Settings/Preferences dialog Ctrl+Alt+S, select Languages & Frameworks | Markdown.

2. Configure the following options:

   Disable automatic language injection in code fences	Do not inject any coding assistance for code blocks.
   Hide errors in code fences	Do not check the syntax for errors.

3. Click OK to apply the changes.

Android Studio Markdown Preview

Diagrams

The Markdown editor can render diagrams defined with Mermaid and PlantUML. This is disabled by default and requires the corresponding Markdown extensions.

Enable diagram support

1. In the Settings/Preferences dialog Ctrl+Alt+S, select Languages & Frameworks | Markdown.

2. Enable either Mermaid or PlantUML under Markdown Extensions.

3. After IntelliJ IDEA downloads the relevant extensions, click OK to apply the changes.

HTML preview

By default, the Markdown editor shows a preview pane next to it for rendered HTML code based on the Markdown file. You can use or in the top right corner of the Markdown editor to show only the editor or the preview pane.

The scrollbars in the editor and in the preview pane are synchronized, meaning that the location in the preview pane corresponds to the location in the source. To disable this, click in the top right corner of the Markdown editor.

To split the editor and preview pane horizontally (top and bottom) instead of the default vertical split, in the Settings/Preferences dialog Ctrl+Alt+S, select Languages & Frameworks | Markdown, and then select Split horizontally under Editor and Preview Panel Layout.

Custom CSS

IntelliJ IDEA provides default style sheets for rendering HTML in the preview pane. These style sheets were designed to be consistent with the default UI themes. You can configure specific CSS rules to make small presentation changes (for example, change the font size for headings or line spacing in lists) or you can provide an entirely new CSS to better match your expected output (for example, if you want to replicate the GitHub Markdown style).

1. In the Settings/Preferences dialog Ctrl+Alt+S, select Languages & Frameworks | Markdown.

2. Configure the settings under Custom CSS:

   • Select Load from URI to specify the location of a custom CSS file.

   • Select Add CSS rules rules to enter specific CSS rules that you want to override.

Reformat Markdown files

IntelliJ IDEA can format Markdown files with proper line wrappings, blank lines, and indentation. For more information, see Reformat and rearrange code.

• From the main menu, select Code | Reformat Code or press Ctrl+Alt+L.

IntelliJ IDEA formats the contents according to the code style settings for Markdown files.

Configure Markdown code style settings

• In the Settings/Preferences dialog Ctrl+Alt+S, select Editor | Code Style | Markdown.

Markdown code style settings include the following:

Configure the options for breaking lines.

Configure the options for nesting text blocks and alignment within a block.

Set the maximum and minimum number of blank lines to keep for various text elements.

Specify which elements should have exactly one space.

Productivity tips

Customize highlighting for Markdown

IntelliJ IDEA highlights various Markdown elements according to the color scheme settings.

1. In the Settings/Preferences dialog Ctrl+Alt+S, select Editor | Color Scheme | Markdown.

2. Select the color scheme, accept the highlighting settings inherited from defaults, or customize them as described in Configuring colors and fonts.

Navigate in a large Markdown file

• Use the Structure tool window Alt+7 or the File Structure popup Ctrl+F12 to view and jump to the relevant headings.

Markdown does not have dedicated syntax for commenting out lines. However, it is possible to emulate a comment line using a link label without an address, like this:

There must be a blank line before the link label.

• Put the caret at the line that you want to comment out and press Ctrl+/.

  This will add a link label with the commented out text in parentheses and a blank line before it if necessary. Press the same shortcut to uncomment.
