mkdx.vim is a markdown plugin that aims to reduce the time you spend formatting your markdown documents. It does this by adding some configurable mappings for files with a markdown filetype. Functions are included to handle lists, checkboxes (even lists of checkboxes!), fenced code blocks, shortcuts, headers and links. In addition to that, this plugin provides a mapping to convert a selection of CSV data to a markdown table. And there's a lot more :D Visit :h mkdx or :h mkdx-helptags for more information.

A copy can be found on This plugin is also compatible with repeat.vim by Tim Pope. Every normal mode mapping can be repeated with the . command. Below you will find configurable settings and examples with default mappings.

This plugin is tested using Vader.vim in vim, nvim and mvim.

To install, use a plugin manager of choice like Vundle or Pathogen.


Plugin 'SidOfc/mkdx'



NeoBundle 'SidOfc/mkdx'



Plug 'SidOfc/mkdx'



cd ~/.vim/bundle
git clone


use 'SidOfc/mkdx'

Pack (Vim's native plugin system).


mkdir -p ~/.vim/pack/plugins/start
cd ~/.vim/pack/plugins/start
git clone

and then in your vimrc, add the following to the bottom:

if !has('nvim')
  augroup MKDX
    au FileType markdown so $HOME/.vim/pack/plugins/start/mkdx/ftplugin/markdown.vim
  augroup END

This is required only for regular Vim, since it does not seem to load the ftplugin/markdown.vim file when needed automatically.


mkdir -p ~/.local/config/nvim/site/pack/plugins/start
cd ~/.local/config/nvim/site/pack/plugins/start
git clone

Quick start

This plugin is extremely customizable, there are a lot of settings and examples to go through. Some of the best settings are disabled because they might not perform on some specific setup or the functionality may interfere with other plugins who are better suited for specific tasks (e.g. highlighting is only a minor 'enhancement' in this plugin).

quick setup

let g:mkdx#settings     = { 'highlight': { 'enable': 1 },
                        \ 'enter': { 'shift': 1 },
                        \ 'links': { 'external': { 'enable': 1 } },
                        \ 'toc': { 'text': 'Table of Contents', 'update_on_write': 1 },
                        \ 'fold': { 'enable': 1 } }
let g:polyglot_disabled = ['markdown'] " for vim-polyglot users, it loads Plasticboy's markdown
                                       " plugin which unfortunately interferes with mkdx list indentation.

The above snippet enables:

  • Folding of inline code blocks and the table of contents
  • Makes dead link detection also check for external links instead of only checking # links
  • Enables shift+enter support for multi line list items (please ensure that it works correctly).
  • Changes the default table of contents text from TOC to Table of Contents
  • Updates the table of contents automatically before saving the file
  • Enables better syntax highlighting for tables, list items, check boxes with certain states, kbd tags and bold+italic markers

There is much more that can be configured, go here for an overview of the defaults or check out the examples below :)



mkdx fold table of contents and fenced code-blocks

Folding in mkdx can be enabled by setting g:mkdx#settings.fold.enable to 1. Both the table of contents and fenced code blocks can be folded independently as well, see g:mkdx#settings.fold.components for more information. We also see a tiny bit of auto update in this example, that shows that the new value gets applied instantly.

NOTE: this functionality conflicts with tpope's vim-markdown plugin. When g:markdown_folding = 1, mkdx will do nothing with foldmethod and foldexpr and leave them intact for vim-markdown.

Insert mode fragment completion

mkdx insert mode fragment completion

When inside a link, typing a url that starts with a # will show a list of autocompletions based on the links of all the headers in the document. This functionality uses Vim's builtin complete (:h complete()) and completefunc (:h completefunc) for autocompletions. Use ctrl+n to select the next entry and ctrl+p to select the previous entry.

When not inside a link, fragment autocompletions will not be triggered and default autocompletion is used instead. To complete a fragment outside of a link, type a # followed by ctrl+n or ctrl+p.

Insert mode autocompletions can be disabled by setting the value of g:mkdx#settings.links.fragment.complete to 0. note: must be enabled for ctrl+n and ctrl+p mappings to be bound.

" :h mkdx-mapping-insert-completions
" :h mkdx-function-insert-ctrl-n-handler
" :h mkdx-function-insert-ctrl-p-handler
" :h mkdx-function-complete-link
" :h mkdx-function-complete
" :h mkdx-plug-ctrl-n-compl
" :h mkdx-plug-ctrl-p-compl
" :h mkdx-plug-link-compl

Dead link detection

mkdx dead detection

Often when writing documentation, you'll find the need to point to some other location on the same page. So you go ahead and write that fragment URL and forget about it. Later you come back to this file and you change the header (thus changing the output fragment for that header), but you forgot you even had a link to it in the first place! A new broken link is born :/

Well, no more -- Press <PREFIX>L and Vim's quickfix window will come to your rescue. It will compare all fragment links in the document to those of the headers and show you which ones don't match. Now you can safely change a header, if you want to know if you broke anything you know the mapping :)

External links will also be checked, your (n/m/g)vim must support either Vim's job or Neovim's job-control in order for this to be enabled. curl and git will also be used to send requests or create an absolute path for relative links. See g:mkdx#settings.links.external.enable for more information and other settings.

" :h mkdx-mapping-quickfix-dead-links
" :h mkdx-function-quickfix-dead-links
" :h mkdx-plug-quickfix-links

Insert fenced code block

Backtick Tilde
mkdx fenced codeblock backticks mkdx fenced codeblock tilde

As seen in the gifs, entering either 3 consecutive ` or ~ characters in insert mode will complete the block and put the cursor at the end of the opening fence to allow adding a language. The behaviour is controlled by and like other mappings, it is only mapped if no mapping exists.

Fence style can be controlled using g:mkdx#settings.tokens.fence. This allows you to use one style for both ` and ~ blocks.

Note that if you want to copy the {rhs} of this mapping in a mapping in your vimrc, you will need to replace <C-o> with a literal ^o character. In vim, this can be achieved by pressing ctrl+v followed by ctrl+o.

" :h mkdx-mapping-insert-fenced-code-block
  inoremap <buffer><silent><unique> ~~~ ~~~<Enter>~~~<C-o>k<C-o>A
  inoremap <buffer><silent><unique> ``` ```<Enter>```<C-o>k<C-o>A

Insert <kbd></kbd> shortcut

mkdx insert keyboard shortcut

This mapping works in insert mode by pressing <+tab. This mapping is just a regular imap that inserts <kbd></kbd> and puts your cursor in the tag afterwards. The behaviour is controlled by and like other mappings, it is only mapped if no mapping exists.

Note that if you want to copy the {rhs} of this mapping in a mapping in your vimrc, you will need to replace <C-o> with a literal ^o character. In vim, this can be achieved by pressing ctrl+v followed by ctrl+o.

" :h mkdx-mapping-insert-kbd-shortcut
imap <buffer><silent><unique> <<Tab> <kbd></kbd><C-o>2h<C-o>cit

Inserting list items

Unordered Numbered
mkdx unordered list mkdx numbered list

When g:mkdx#settings.enter.enable is set (default on), new list tokens will be inserted when editing a markdown list. This happens on any enter in insert mode or o and O in normal mode by default. Additionally, if the list item contains a checkbox ([ ] - any state possible) that will also be appended to the newly inserted item.

Sometimes, you might need to write a multi-line list item, this can be achieved by enabling g:mkdx#settings.enter.shift. Once enabled, pressing shift+enter will place the cursor on a new line, indented to where the text started on the previous line. Press shift+enter while you want to add lines to the current item, a regular enter will create a new list item at the previous indentation level.

" :h mkdx-mapping-list-items
" :h mkdx-setting-enter-enable
" :h mkdx-setting-enter-shift
" :h mkdx-setting-tokens-list
" :h mkdx-function-enter-handler
" :h mkdx-function-shift-enter-handler

Indenting / unindenting numbered list items

mkdx indent/unindent list items

Numbered list items will be renumbered upon indenting / unindenting. The algorithm for this is still pretty basic but attempts to ensure correct nesting. This feature uses tab and shift+tab to indent and unindent respectively.

When g:mkdx#settings.insert_indent_mappings is enabled insert mode indent and unindent using ctrl+t and ctrl+d will also renumber numbered markdown lists.

" :h mkdx-mapping-list-items
" :h mkdx-function-indent-handler
" :h mkdx-function-insert-indent-handler

Toggling lines from / to task items

mkdx toggle checkbox line

Checkboxes can be toggled using <PREFIX>t. This will cause a checkbox to be prepended before the line if it doesn't exist. The checkbox will be removed instead, if it exists. The initial state can be defined using g:mkdx#settings.checkbox.initial_state.

When toggling a checkbox in a list or checklist, the checkbox will be added / removed accordingly:

- list item           => - [ ] list item
- [ ] checklist item  => - checklist item
* [ ] checklist item  => * checklist item
1. [ ] checklist item => 1. checklist item

Note: the list / checklist support has been added in version 0.4.1. Prior to that, the checkbox would be inserted at the start of the line instead of after the list token.

" :h mkdx-mapping-toggle-checkbox
" :h mkdx-function-toggle-checkbox-task

Toggling lines from / to list items

mkdx toggle list line

Lists can be toggled using <PREFIX>ll. This will cause a list token to be inserted. When present, it will be removed.

When toggling a checkbox or a checklist item, the list token will be added / removed accordingly:

[ ] checkbox item     => - [ ] checkbox item
- [ ] checklist item  => - checklist item
* [ ] checklist item  => * checklist item
1. [ ] checklist item => 1. checklist item

Note: the checklist support has been added in version 0.4.1. Prior to that, tokens other than g:mkdx#settings.tokens.list weren't toggled.

" :h mkdx-mapping-toggle-list
" :h mkdx-function-toggle-list

Toggling lines from / to checklist items

mkdx toggle checklist line

Checklists can be toggled using <PREFIX>lt. This will cause a list token followed by a checkbox to be prepended before the line if it doesn't exist. If it is already present, it will be removed. Like Checkboxes, the initial state of the checkbox can be defined using: g:mkdx#settings.checkbox.initial_state.

If the current line or selection is one or multiple list items, a checkbox with state of g:mkdx#settings.checkbox.initial_state will be added:

- list item  => - [ ] list item
* list item  => * [ ] list item
1. list item => 1. [ ] list item

If the current line or selection is one or multiple checkboxes, a g:mkdx#settings.tokens.list will be added. Any state the checkbox is in will be preserved:

[ ] list item  => - [ ] list item
[x] list item  => - [x] list item

note: the list item / checkbox support has been added in version 0.4.1. Prior to that, toggling checklists only performed a check to see if a checklist item was present or not.

" :h mkdx-mapping-toggle-checklist
" :h mkdx-function-toggle-checklist

Completing Checkboxes / Checklists

Single checkbox: mkdx toggle checkbox

Checkbox in checklist: mkdx update checklist

Checkboxes can be checked using <PREFIX>= and <PREFIX>-. checking a checkbox means going to the previous or next mark in the list of g:mkdx#settings.checkbox.toggles. When checking an item which is nested in a list, the parent and child list items will be updated as well. Automatic updating of checkboxes can be disabled by setting g:mkdx#settings.checkbox.update_tree. All manipulations work fine in visual as well as normal mode.

You can also see that the checkboxes are highlighted differently depending on state. This is an opt-in setting which you must enable explicitly in your vimrc. See g:mkdx#settings.highlight.enable for more information.

A file might not always be indented correctly, the solution to this is g:mkdx#settings.enter.malformed. This setting is enabled by default, it rounds invalid (indentation not divisible by :h shiftwidth) either up or down to the nearest indentation level. In the examples below, the shiftwidth is set to 4. The second item is indented by 3 spaces and the third item is indented by 5 spaces. since 3 is closer to 4 than 0, it will become 4. In the case of 5, it's closer to 4 than 8 and will also become 4.

Toggling and promoting / demoting Headers

mkdx toggle header

Increment or decrement a heading with <PREFIX>[ and <PREFIX>]. As can be seen in the gif, headings can be toggled as well as promoted / demoted with these mappings. The header character can be changed using g:mkdx#settings.tokens.header.

" :h mkdx-mapping-increment-header-level
" :h mkdx-mapping-decrement-header-level
" :h mkdx-function-toggle-header

Toggling <kbd /> shortcuts

mkdx toggle kbd shortcuts

Note: does not work with multiline selection

Quickly toggle plain text shortcuts to markdown shortcuts and back with <PREFIX>'.

" :h mkdx-mapping-toggle-kbd-shortcut
" :h mkdx-function-toggle-to-kbd

Toggling Quotes

mkdx toggle quotes

Toggle quotes on the current line or a visual selection with <PREFIX>'.

" :h mkdx-mapping-toggle-quote
" :h mkdx-function-toggle-quote

Typing a multi-paragraph quote

In some cases you may want to quote more than one line or block of text. To cover this case, typing an additional space followed by an enter after an empty quote line will keep the symbol and create a new empty quote line below it:

> this is some text in a quote

Toggle links

mkdx wrap text in link

Wrap the word under the cursor or a visual selection in an empty markdown link with <PREFIX>ln. You'll end up in insert mode with your cursor between the parens, e.g. (|) where the pipe (|) character is the cursor.

This mapping also takes a count, like the other wrap mappings bold / italic / inline-code / strikethrough. Doing this will wrap count words from cursor position in a link.

Additionally, as of version 1.9.2, regular markdown links (not images!) can also be removed using <PREFIX>ln. count will be ignored when removing a link.

If what you're wrapping is an image (only works with visual selections at the moment), an image link will be created instead. To disable this behaviour, see: g:mkdx#settings.image_extension_pattern.

" :h mkdx-mapping-wrap-text-in-link
" :h mkdx-function-wrap-link

Toggle as bold / italic / inline-code / strikethrough

Normal mode mkdx wrap text in bold / italic / inline-code / strikethrough normal

Visual mode mkdx wrap text in bold / italic / inline-code / strikethrough visual

Toggle the word (anywhere) under the cursor or a visual selection using the following mappings:

As with all other mappings, all the normal mode mappings are repeatable. mkdx also supports supplying an optional count to these mappings, e.g.

Given text Hello world where the cursor can be anywhere inside the first word 2+<PREFIX>b will wrap both Hello and world: **Hello world**. This works for all the mappings above.

As of version 1.9.2 mkdx also supports unwrapping of wrapped text in italic / bold / inline-code / strikethrough styles. When unwrapping, mkdx ignores any supplied count arguments.

NOTE: mkdx wraps using Vim's 'word' (:h word), sometimes 'word' will not include command characters such as - which means mkdx may fail to wrap hello-world as one word. To fix this the iskeyword option can be overridden to include - or any other character:

augroup markdown
    " Include dash in 'word'
    autocmd FileType markdown setlocal iskeyword+=-
augroup END

Convert CSV to table (and back)

mkdx convert csv to table

Convert visually selected CSV rows to a markdown table with <PREFIX>,. The first row will be used as a header. A separator will be inserted below the header. Default and specific column alignment options are also available, see: g:mkdx#settings.table.align for more. The divider (|) as well as the header divider (-) can be changed with g:mkdx#settings.table.divider and g:mkdx#settings.table.header_divider. The above example contains a simple unqouted example but as of version 1.4.2, quoted CSV is also supported.

" :h mkdx-mapping-csv-to-markdown-table
" :h mkdx-setting-table-align
" :h mkdx-setting-table-divider
" :h mkdx-setting-table-header-divider
" :h mkdx-function-tableize

Jump to header

mkdx jump to header

Press <PREFIX>j to jump to a fragment identifier within the document. Every link starting with a # symbol is considered a fragment identifier. Markdown, wiki links, and HTML formats are supported. Before performing a jump, the current cursor position will be added to the jumplist (:h jumplist). This allows you to jump back and forth between that header and the selected link using ``. This behaviour can be disabled by overriding g:mkdx#settings.links.fragment.jumplist.

" :h mkdx-setting-links-fragment-jumplist
" :h mkdx-plug-jump-to-header
" :h mkdx-function-jump-to-header
" :h mkdx-mapping-jump-to-header

Jump to next / previous header

Use ]] to jump to the next header and [[ to jump to the previous header. Both mappings support counts and do not wrap around.

Generate or update TOC

mkdx generate or update table of contents

Press <PREFIX>i to insert a table of contents at cursor position if one does not exist, otherwise updates the existing TOC. the text used in the heading can be changed using g:mkdx#settings.toc.text and the list style can be changed using g:mkdx#settings.toc.list_token. Stuff inside fenced code blocks is excluded too.

If you want to place the TOC always as the [N]th header, see g:mkdx#settings.toc.position.

" :h mkdx-mapping-generate-or-update-toc
" :h mkdx-function-generate-toc
" :h mkdx-function-update-toc
" :h mkdx-function-generate-or-update-toc

Generate or update TOC as <details>

mkdx generate or update table of contents as details

Github supports the <details> and <summary> tags! With these, we can make an expandable table of contents (like this README). Unfortunately though, markdown isn't supported inside the <details> tag, not even with markdown=1 (not from what I've tried anyway, let me know if you do!). So instead the TOC itself will be rendered as HTML nested <ul> tags with <li><a></a></li> tags.

NOTE: This requires you to enable g:mkdx#settings.toc.details.enable!

Click to expand example

Note: When wrapping the TOC inside a details tag, you can optionally wrap nested items with a lot of children by using g:mkdx#settings.toc.details.nesting_level and g:mkdx#settings.toc.details.child_count. Check the Table of Contents for an example :)

Open TOC in quickfix window

mkdx open toc in quickfix

Press <PREFIX>I to load all the markdown headers in a quickfix window. You can jump around using regular quickfix commands afterwards, as shown in the gif using :cn for example.

" :h mkdx-mapping-quickfix-table-of-contents
" :h mkdx-function-quickfix-headers

Open TOC using fzf instead of quickfix window

mkdx open toc using fzf

This is not built-in to the plugin but I just thought "why not, I'd use that". So I started working on a little snippet in my vimrc (included some comments here):

fun! s:MkdxGoToHeader(header)
    " given a line: '  84: # Header'
    " this will match the number 84 and move the cursor to the start of that line
    call cursor(str2nr(get(matchlist(a:header, ' *\([0-9]\+\)'), 1, '')), 1)

fun! s:MkdxFormatHeader(key, val)
    let text = get(a:val, 'text', '')
    let lnum = get(a:val, 'lnum', '')

    " if the text is empty or no lnum is present, return the empty string
    if (empty(text) || empty(lnum)) | return text | endif

    " We can't jump to it if we dont know the line number so that must be present in the outpt line.
    " We also add extra padding up to 4 digits, so I hope your markdown files don't grow beyond 99.9k lines ;)
    return repeat(' ', 4 - strlen(lnum)) . lnum . ': ' . text

fun! s:MkdxFzfQuickfixHeaders()
    " passing 0 to mkdx#QuickfixHeaders causes it to return the list instead of opening the quickfix list
    " this allows you to create a 'source' for fzf.
    " first we map each item (formatted for quickfix use) using the function MkdxFormatHeader()
    " then, we strip out any remaining empty headers.
    let headers = filter(map(mkdx#QuickfixHeaders(0), function('<SID>MkdxFormatHeader')), 'v:val != ""')

    " run the fzf function with the formatted data and as a 'sink' (action to execute on selected entry)
    " supply the MkdxGoToHeader() function which will parse the line, extract the line number and move the cursor to it.
    call fzf#run(fzf#wrap(
            \ {'source': headers, 'sink': function('<SID>MkdxGoToHeader') }
          \ ))

" finally, map it -- in this case, I mapped it to overwrite the default action for toggling quickfix (<PREFIX>I)
nnoremap <silent> <Leader>I :call <SID>MkdxFzfQuickfixHeaders()<Cr>

Using the menu

The plugin comes with builtin menu support if your vim has('menu'). The menu will become available after you've opened a file with a filetype of markdown. Actions can be executed from the menu in MacVim. More information about each mapping can be found in the Vim / Neovim versions.

MacVim NeoVim / Vim
mkdx macvim menu mkdx neovim / vim menu

To view the menu in NeoVim / Vim, run (after opening a markdown file):

" :h mkdx-menu
:menu Plugin.mkdx


IMPORTANT: within your .vimrc / config/nvim/init.vim files you will not be able to use the 'short' style. these are only intended to be used in EX mode (when typing a : command).

All the settings used in mkdx are defined in a g:mkdx#settings hash. If you still have other g:mkdx# variables in your .vimrc, they should be replaced with an entry in g:mkdx#settings instead. Going forward, no new g:mkdx# variables will be added, only g:mkdx#settings will be extended. To see a mapping of new settings from old variables, see this README. For a full list of defaults, visit :h mkdx-settings, for an overview of all settings visit :h mkdx-toc-settings To overwrite a setting, write it as seen in :h mkdx-settings in your .vimrc:

" :h mkdx-settings
let g:mkdx#settings = { 'enter': { 'enable': 0 } }

NOTE: The method used above somewhat relies on exists('*dictwatcheradd') which is Neovim only. If you intend to :so % your .vimrc file, please use the following instead:

" :h mkdx-settings
call mkdx#configure({ 'enter': { 'enable': 0 } })

The above will disable the g:mkdx#settings.enter.enable setting. For backwards compatibility, g:mkdx# variables are merged into the defaults. This happens before any g:mkdx#settings hash defined in .vimrc is merged with the defaults. So while g:mkdx# variables still work, they are overwritten when you explicitly define them in a g:mkdx#settings variable.

Settings defined in .vimrc are merged with the defaults during initial loading of the plugin. To overwrite a setting while editing:

" :h mkdx-settings
:let g:mkdx#settings.enter.enable = 0


This setting is off by default. When enabled, this will allow ctrl+t and ctrl+d to renumber numbered markdown lists.

" :h mkdx-setting-insert-indent-mappings
:let g:mkdx#settings.insert_indent_mappings = 0


mkdx enhances gf and gx within markdown buffers. The main difference is that you can open files / urls / images with the cursor positioned anywhere in a markdown link. Additionally, these mappings can also be used in visual mode and will be applied to the current selection in that case. Otherwise they will work normally.

By enabling this setting, these two mappings are merged into one, so both gf and gx will work exactly the same. Functionalities from both will work for each mapping, so you can now use gf OR gx to open local files as well as urls / images externally.

mkdx uses g:mkdx#settings.image_extension_pattern to determine wether or not a file is an image and should be opened by an external application.

For other files such as doc or pdf mkdx relies on the file command to determine if a file should be opened inside (n)vim or using for example libreoffice.

mkdx uses open / xdg-open behind the scenes, on macOS this will work out of the box, on linux make sure the xdg-utils package is installed and that you can run open xdg-utils can be installed by running sudo apt install xdg-utils in your terminal.

Check external links in the background is disabled by default. HTTP requests will be sent using a curl command with the following layout:

curl -L -I -s --no-keepalive -o /dev/null -A [g:mkdx#settings.links.external.user_agent] -m [g:mkdx#settings.links.external.timeout] -w "%{http_code}" [URL]'

As can be seen from the example two additional settings are used in this request:

When a relative URL is encountered, mkdx attempts to convert it to an absolute path. This only works inside a git repository at the moment, git ls-remote output will be used to do the conversion. You can override this behaviour by setting a custom host with Relative link checking can be disabled all together by setting g:mkdx#settings.links.external.relative to 0;

" :h mkdx-setting-links-external-enable
let g:mkdx#settings = { 'links': { 'external': { 'enable': 0 } } }


This is the maximum time in seconds a request may take. By default it is set to 3. After this time, the request is cancelled and added to the quickfix list.

" :h mkdx-setting-links-external-timeout
let g:mkdx#settings = { 'links': { 'external': { 'timeout': 3 } } }

When a host is supplied, mkdx will not attempt to do git ls-remote detection and instead, prepends host string provided to any absolute or relative link url. Since these links can either be relative (url) or absolute (/url) some additional checks are executed to prevent double slashes e.g: localhost:3000//url. Therefore you can safely append or remove a trailing / from your host.

As an example, say you have the following markdown link in your file:


The git ls-remote command will be executed to construct a base for the relative link. both SSH and HTTP hosts are parsed to a base URL. Additionally, when constructing the base, we need to know the current branch since for example, github appends blob/[BRANCHNAME] to every URL as well. To extract this information, a git branch command is run. The output link will look like this:

See <a href="">CONTRIBUTING</a>

If you're running a static site generator and would like to know if every link works, you can set it like so:

:let = 'localhost:5000'

Using the same link as an example, the output link will instead, look like this:

See <a href="http://localhost:5000/">CONTRIBUTING</a>

The host can be changed at any given time during runtime, the next time a dead link check is run, the new host will be used instead.

" :h mkdx-setting-links-external-host
let g:mkdx#settings = { 'links': { 'external': { 'host': '' } } }


When set to 0, relative links will be ignored while checking the document for dead links. Relative URL's are defined as link paths that do not start with a # (fragment URL) or http (protocol). Therefore both relative (url) and absolute (/url) URL's are "relative" in this context, as no host is provided. When is empty, mkdx attempts to construct an absolute path using git ls-remote output.

" :h mkdx-setting-links-external-relative
let g:mkdx#settings = { 'links': { 'external': { 'relative': 1 } } }


Specify an actual user agent to prevent being blocked from a website. If you don't like being Chrome/9001 then feel free to change it into anything you like :)

" :h mkdx-setting-links-external-ua
let g:mkdx#settings = { 'links': { 'external': { 'user_agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/9001.0.0000.000 vim-mkdx/1.10.0' } } }


When conceallevel=2 mkdx hides link URLs by default. This can be disabled by setting g:mkdx#settings.links.conceal to 0.

" :h mkdx-setting-links-conceal
let g:mkdx#settings = { 'links': { 'conceal': 1 } }


Specify wether or not to add the cursor position before jumping to the jumplist (:h jumplist). This setting is enabled by default, set it to 0 to disable.

" :h mkdx-setting-links-fragment-jumplist
" :h mkdx-function-jump-to-header
" :h mkdx-plug-jump-to-header
let g:mkdx#settings = { 'links': { 'fragment': { 'jumplist': 1 } } }


Autocomplete fragment links in insert mode. Set to 0 to disable, must be enabled for ctrl+n and ctrl+p to be mapped.

This setting is auto updated when available.

" :h mkdx-setting-links-fragment-complete
let g:mkdx#settings = { 'links': { 'fragment': { 'complete': 1 } } }


Configure the pumheight. Default 15. Set to 0 to prevent pumheight from being modified.

" :h mkdx-setting-links-fragment-pumheight
let g:mkdx#settings = { 'links': { 'fragment': { 'pumheight': 15 } } }


Configure the completeopt used for fragment completion. Default noinsert,menuone. Set to 0 to prevent completeopt from being modified.

If you have set completeopt in your vimrc you may want to set this to 0 to persist your own preferences while editing markdown files.

" :h mkdx-setting-links-fragment-completeopt
let g:mkdx#settings = { 'links': { 'fragment': { 'completeopt': 'noinsert,menuone' } } }


Defines the extensions to search for when identifying the type of link that will be generated when wrapping text in a link. Setting it to an empty string disables image wrapping and a regular empty markdown link will be used instead.

" :h mkdx-setting-image-extension-pattern
let g:mkdx#settings = { 'image_extension_pattern': 'a\?png\|jpe\?g\|gif' }


This setting enables the restoration of the last visual selection after performing an action in visual mode:

" :h mkdx-setting-restore-visual
let g:mkdx#settings = { 'restore_visual': 1 }

All mappings are prefixed with a single prefix key. If a mapping contains <PREFIX> key, it is the value of this variable. If you do not like the default (<leader>) you can override it:

" :h mkdx-setting-map-prefix
let g:mkdx#settings = { 'map': { 'prefix': '<leader>' } }

If you'd rather full control over what is mapped, you can opt-out all together by setting it to 0. Note: that the plugin checks if a keybind exists before creating it. Mappings defined in your .vimrc will not be overwritten.

" :h mkdx-setting-map-enable
let g:mkdx#settings = { 'map': { 'enable': 1 } }


Defines the list of states to use when toggling a checkbox. It can be set to a list of your choosing. Special characters must be escaped! Also, the list of toggles must contain at the very least, 2 items!

" :h mkdx-setting-checkbox-toggles
let g:mkdx#settings = { 'checkbox': { 'toggles': [' ', '-', 'x'] } }

" GFM supported list (e.g. on GitHub)
let g:mkdx#settings = { 'checkbox': { 'toggles': [' ', 'x'] } }


With this setting on, checkboxes that are toggled within checklists (lists of checkboxes) cause parent and child list items to be updated automatically. The states from g:mkdx#settings.checkbox.toggles are used to check and update the statusses of any parents. Children are force updated to the same token of their parent. To disable this behaviour entirely, set this value to 0. If you do not want children to be updated, set this value to 1 instead.

" :h mkdx-setting-checkbox-update-tree
let g:mkdx#settings = { 'checkbox': { 'update_tree': 2 } }


When toggling between checkbox/checklist lines, this defines what the default value of each inserted checkbox should be.

" :h mkdx-setting-checkbox-initial-state
let g:mkdx#settings = { 'checkbox': { 'initial_state': ' ' } }


Add custom attributes to the syn match statements of the following highlight groups:

  • mkdxCheckboxEmpty
  • mkdxCheckboxPending
  • mkdxCheckboxComplete
" :h mkdx-setting-checkbox-match-attrs
let g:mkdx#settings = { 'checkbox': {
  \ 'match_attrs': {
  \   'mkdxCheckboxEmpty': '',
  \   'mkdxCheckboxPending': '',
  \   'mkdxCheckboxComplete': '',
  \ }
  \ } }


If you want to use a different style for markdown headings (h1, h2, etc...).

This setting is auto updated when available.

" :h mkdx-setting-tokens-header
let g:mkdx#settings = { 'tokens': { 'header': '#' } }


Used by g:mkdx#settings.enter.enable. This is the list of tokens that are supported by default. Since numbers are handled differently, they are not included in this list but they are supported.

" :h mkdx-setting-tokens-enter
let g:mkdx#settings = { 'tokens': { 'enter': ['-', '*', '>'] } }


Defines the fencing style to use when inserting a fenced code block. By default it is set to an empty string, in which case typing tildes will result in a fenced code block using tildes and typing backticks results in a code block using backticks.

This value can be set to a ` or a ~ character. When set, the same style will always be used for fenced code blocks.

This setting is auto updated when available.

" :h mkdx-setting-tokens-fence
let g:mkdx#settings = { 'tokens': { 'fence': '' } }


This token is used for italicizing the current word under the cursor or a visual selection of text. See this section for more details.

" :h mkdx-setting-tokens-italic
let g:mkdx#settings = { 'tokens': { 'italic': '*' } }


This token is used for bolding the current word under the cursor or a visual selection of text. See this section for more details.


This token is used for striking the current word under the cursor or a visual selection of text. See this section for more details.

Note: this setting has been added in version 1.7.0. Prior to that, <strike>...</strike> tags will always be used to create strikethrough text.

" :h mkdx-setting-tokens-bold
let g:mkdx#settings = { 'tokens': { 'bold': '**' } }


This token defines what list markers should be inserted when toggling list / checklist items.

" :h mkdx-setting-tokens-list
let g:mkdx#settings = { 'tokens': { 'list': '-' } }


Change the separator used for table headings in markdown tables.

" :h mkdx-setting-table-header-divider
let g:mkdx#settings = { 'table': { 'header_divider': '-' } }


You can also change the separator used in markdown tables.

" :h mkdx-setting-table-divider
let g:mkdx#settings = { 'table': { 'divider': '|' } }


Control the alignment of content within table columns. Its value is a dictionary with keys center, left, right and default. The default value is used when a column name is not found in any of the center, left or right lists.

    \ 'left':    [],
    \ 'center':  [],
    \ 'right':   [],
    \ 'default': 'center'
\ }

If you were to add name to the left list, e.g. { 'left': ['name'] } and the first row of your CSV has a column with the content name, that column will be left aligned (|:----|). Any other column would be centered (|:---:|) because they do not appear in any list so the default value 'center' is used.

" :h mkdx-setting-table-align
let g:mkdx#settings = { 'table': { 'align': {
        \ 'left':    [],
        \ 'center':  [],
        \ 'right':   [],
        \ 'default': 'center' } } }

This setting is enabled by default, when enabled, pressing tab and shift+tab on numbered list items will indent / unindent them and also renumber the list accordingly.

NOTE: This causes a conflict when UltiSnips also uses tab to expand snippets! Either disable this functionality or remap it to some other key combination.

" :h mkdx-setting-tab-enable
" :h mkdx-function-indent-handler
let g:mkdx#settings = { 'tab': { 'enable': 1 } }


This setting enables auto-appending list items when you are editing a markdown list. When enter is pressed, a function is executed to detect wether or not to insert a new list item or just do a regular enter. unordered lists and numbered lists are both handled correctly.

NOTE: When this setting is enabled, mkdx will execute a setlocal formatoptions-=r to prevent duplicate list markers from being inserted. This setting is auto updated when available.

" :h mkdx-setting-enter-enable
let g:mkdx#settings = { 'enter': { 'enable': 1 } }


Disabled by default, when enabled pressing enter will first close any visible popup menu before executing mkdx's enter handler.

" :h mkdx-setting-enter-close-pum
let g:mkdx#settings = { 'enter': { 'close_pum': 0 } }


This setting defines increment done for each new item in numbered list, Default value is 1 setting 0 will keep current index on new item.

" :h mkdx-setting-enter-increment
let g:mkdx#settings = { 'enter': { 'increment': 0 } }


When enabled, pressing shift+enter will indent the next line upto the level of the text on the current line. No list tokens will be prepended. This is useful when you want to write a multi-line list item and want to start at the correct indentation level. For example, given this list (cursor indicated by a "|" character):

- [ ] a list item
- [ ] a list item|
- [ ] a list item

Pressing shift+enter will produce:

- [ ] a list item
- [ ] a list item
- [ ] a list item

This works for any list type supported by mkdx. When shift+enter is pressed while not at the end of the line, the text after the cursor position is carried over to the next line at the correct indentation.

Note: this setting is disabled by default due to the sketchy handling of shift+enter in different terminal emulators. Some emulators send the same codes for enter and shift+enter which means (n)vim cannot distinguish one from another. This can usually be fixed by setting them manually for your emulator, included from this SO answer:

I managed to correct my terminal key-code for Shift+Enter by sending the key-code Vim apparently expects. Depending on your terminal, (Adding Ctrl+Enter as a bonus!)

iTerm2, open PreferencesProfilesKeys[+] (Add)

  • Keyboard shortcut: (Hit Shift+Enter)
  • Action: Send Escape Sequence
  • Esc+ [[13;2u Repeat for Ctrl+Enter, with sequence: [[13;5u

urxvt, append to your .Xresources file:

URxvt.keysym.S-Return:     \033[13;2u
URxvt.keysym.C-Return:     \033[13;5u

Alacritty, under key_bindings, add following to your ~/.config/alacritty/alacritty.yml:

- { key: Return,   mods: Shift,   chars: "\x1b[13;2u" }
- { key: Return,   mods: Control, chars: "\x1b[13;5u" }
" :h mkdx-setting-enter-shift
" :h mkdx-function-shift-enter-handler
:let g:mkdx#settings = { 'enter': { 'shift': 0 } }


This setting overwrites normal mode o in markdown files and causes o to work like pressing <enter> at the end of the line this means that lists, checklists, checkboxes, quotes etcetera are also inserted when pressing o in normal mode in addition to <enter> in insert mode. Note that g:mkdx#settings.enter.enable must be 1 for this to work.

" :h mkdx-setting-enter-o
let g:mkdx#settings = { 'enter': { 'o': 1 } }


This setting enables O in normal mode to prepend list items above the current line, your cursor will be placed after the newly added item. Like g:mkdx#settings.enter.o, checkboxes are also added if they are present on the cursor line. Note that g:mkdx#settings.enter.enable must be 1 for this to work.

" :h mkdx-setting-enter-shifto
let g:mkdx#settings = { 'enter': { 'shifto': 1 } }


This setting defines behaviour to use when working with improperly indented markdown lists. At the moment it works for checklist items that do not have an indent() which is divisible by shiftwidth. In which case the indent will be rounded up to the next indent if it is greater than s:sw() / 2 otherwise it will be rounded down to the previous indent.

" :h mkdx-setting-enter-malformed
let g:mkdx#settings = { 'enter': { 'malformed': 1 } }


Defines the text to use for the table of contents header itself.

This setting is auto updated when available.

" :h mkdx-setting-toc-text
let g:mkdx#settings = { 'toc': { 'text': 'TOC' } }


Defines the list token to use in the generated TOC.

" :h mkdx-setting-toc-list-token
let g:mkdx#settings = { 'toc': { 'list_token': '-' } }


As easy as it is to update the table of contents manually, it is just as easy to forget :) This setting is disabled by default, set it to 1 to enable it and never worry about updating your TOC ever again. When the TOC hasn't yet been generated and g:mkdx#settings.toc.position isn't 0, the TOC will be generated at given position (or as the last header of the document if there aren't enough headers). Otherwise, you will first have to generate the TOC once manually in the desired position and then it will be updated too.

Note: this only works if your vim has('autocmd').

" :h mkdx-setting-toc-update-on-write
let g:mkdx#settings = { 'toc': { 'update_on_write': 0 } }


The position at which to place the TOC, 0 is used for cursor. If a number > 0 is supplied, the TOC will be generated ABOVE that header. e.g. setting it to 1 will cause it to be the first heading of your document.

This setting is auto updated when available.

" :h mkdx-setting-toc-position
let g:mkdx#settings = { 'toc': { 'position': 0 } }


This setting controls wether the generated TOC will be output as a regular markdown list or inside a <details> tag. See: Generate or update TOC as <details> for an example. By default, this option is disabled. To use it, set it's value to 1 instead.

This setting is auto updated when available.

" :h mkdx-setting-toc-details-enable
let g:mkdx#settings = { 'toc': { 'details': { 'enable': 0 } } }


With g:mkdx#settings.toc.details.enable set to 1, a <summary> tag will also be generated inside the resulting <details> tag. This tag contains the text that will be displayed next to the "". The default value has a special placeholder {{toc.text}}. This will be replaced with the value of g:mkdx#settings.toc.text upon generation.

This setting is auto updated when available.

" :h mkdx-setting-toc-details-summary
let g:mkdx#settings = { 'toc': { 'details': { 'summary': 'Click to expand {{toc.text}}' } } }


Disabled by default. This setting allows additional <details> to be generated from a specified nesting level. When enabled, it relies on a TOC wrapped as details to already be present or g:mkdx#settings.toc.details.enable to be 1.

Note: 1 is always added to the specified amount, this is to prevent all H1's from being wrapped when setting this value to 0. This means that a nesting level of 5 wraps H6 list items. Think of this value as the 'nth' nesting level, where 0 would make no sense to 'nest' since it is at the root of the list.

This setting is auto updated when available.

" :h mkdx-setting-toc-details-nesting-level
let g:mkdx#settings = { 'toc': { 'details': { 'nesting_level': -1 } } }


When g:mkdx#settings.toc.details.nesting_level is enabled, this setting defines when to wrap children of a specific list item. This is done by counting the children and either wrapping when the amount of items is greater than or equal to this setting.

This setting is auto updated when available.

" :h mkdx-setting-toc-details-child-count
let g:mkdx#settings = { 'toc': { 'details': { 'child_count': 5 } } }


This setting is like g:mkdx#settings.toc.details.summary but applies to the nested details summary. A special {{count}} placeholder can be used in the supplied string which will be replaced with the amount of list items wrapped in the details tag.

This setting is auto updated when available.

" :h mkdx-setting-toc-details-child-summary
let g:mkdx#settings = { 'toc': { 'details': { 'child_summary': 'show {{count}} items' } } }


This setting enables mkdx highlighting. mkdx attempts to improve highlighting for the following syntax in a markdown file:

  • Tables
  • List items
  • Checkboxes (including their state, [x] (done), [-] (doing, not compatible with GH), and [ ] (todo))
  • Fenced code blocks with tilde (this is just about highlight color of tilde, not code inside it)
  • bold-italic text (text which is both bold and italic)
  • keyboard tags
  • CriticMarkup
  • YAML front-matter
  • Inline code blocks

All other syntax remains untouched. To see all highlight groups, visit :h mkdx-highlighting, to see an overview of all highlight groups, visit :h mkdx-toc-highlighting

NOTE: syntax highlighting is opt-in by default. This means you must explicitly enable this feature to use it. The reason behind this is that this plugin is not a syntax plugin and maybe you are already using one that does such a thing in a way that works better for you. You can see it in action in the Completing checkboxes / checklists examples.

This setting is auto updated when available.

" :h mkdx-setting-highlight-enable
" :h mkdx-highlighting
let g:mkdx#settings = { 'highlight': { 'enable': 0 } }


This setting is enabled by default. When enabled, YAML frontmatter is highlighted.

" :h mkdx-setting-highlight-frontmatter-yaml
let g:mkdx#settings = { 'highlight': { 'frontmatter': { 'yaml': 1 } } }


TOML frontmatter is disabled by default since it is less common than YAML. This allows markdown files to be loaded faster for people that don't use TOML frontmatter.

" :h mkdx-setting-highlight-frontmatter-toml
let g:mkdx#settings = { 'highlight': { 'frontmatter': { 'toml': 0 } } }


JSON frontmatter is disabled by default since it is less common than YAML. This allows markdown files to be loaded faster for people that don't use JSON frontmatter.

" :h mkdx-setting-highlight-frontmatter-json
let g:mkdx#settings = { 'highlight': { 'frontmatter': { 'json': 0 } } }


This setting controls wether or not to update the document after changing certain variables. Currently, this only works if your vim has('*dictwatcheradd').

The following settings are automatically updated:

" :h mkdx-setting-auto-update-enable
let g:mkdx#settings = { 'auto_update': { 'enable': 1 } }


Controls wether or not to fold fenced (``` / ~~~) code blocks and / or the table of contents (when generated by mkdx). Behaviour can be controlled using g:mkdx#settings.fold.components. Folding is disabled by default, set it to 1 to enable it.

NOTE: when g:markdown_folding is enabled, this functionality will no-op because they do not work together nicely!

This setting is auto updated when available.

" :h mkdx-setting-fold-enable
:let g:mkdx#settings = { 'fold': { 'enable': 0 } }


Controls which components to fold when g:mkdx#settings.fold.enable is enabled. Currently, two components can be folded, 'toc' and 'fence'. items can be added and removed from the list as needed.

This setting is auto updated when available.

" :h mkdx-setting-fold-components
:let g:mkdx#settings = { 'fold': { 'components': ['toc', 'fence'] } }


Mappings can be turned off all together with The plugin checks if a mapping exists before creating it. If it exists, it will not create the mapping. In case a mapping that this plugin provides doesn't work, please check if you have it in your .vimrc and also try :verbose map [mapping] where [mapping] is the mapping that doesn't work e.g. <Cr> or gf.

The below list contains all mappings that mkdx creates by default. To remap functionality: remapping functionality. To prevent mapping of a key from happening, see: unmapping functionality.

Remapping functionality

<Plug> mappings can easily be remapped to any other key you prefer. When a <Plug>(mkdx-*) mapping is found, mkdx will not create the default mapping for that <Plug>. If you want to disable functionality, see: Unmapping functionality.

" this will remap <leader>q in every filetype, not very handy in most cases
nnoremap <leader>q <Plug>(mkdx-quickfix-toc)

" to keep it limited to markdown files, one can use an "autocommand".
" First, make sure we don't create the default mapping when entering markdown files.
" All plugs can be disabled like this (except insert mode ones, they need "imap" instead of "nmap").
nmap <Plug> <Plug>(mkdx-quickfix-toc)

" then create a function to remap manually
fun! s:MkdxRemap()
    " regular map family can be used since these are buffer local.
    nmap <buffer><silent> <leader>q <Plug>(mkdx-quickfix-toc)
    " other overrides go here

" finally, add a "FileType" autocommand that calls "s:MkdxRemap()" upon entering markdown filetype
augroup Mkdx
    au FileType markdown,mkdx call s:MkdxRemap()
augroup END

Unmapping functionality using <Nop>

If you want to unmap specific functionality, you'll have to define a mapping for it. This is required because the plugin maps its keys when opening a markdown file, so if you unmap something, it will still get mapped to other markdown buffers. To disable any map, first find it here or at: :h mkdx-mappings.

Say you want to disable toggling next checkbox state (mapped to <PREFIX>=). In your .vimrc, add the following:

" this will disable toggling checkbox next in normal mode.
nmap <leader>= <Nop>

" this will disable toggling checkbox next in visual mode.
vmap <leader>= <Nop>

If you only want to do this for markdown files, refer to the previous snippet using the au command.

The mappings are checked using the value of so you may need to check its value first by running the following: :echo A better way to prevent mkdx from mapping keys is by remapping <Plug> mappings.

Unmapping functionality using <Plug>

If you don't know what a <Plug> is, it is a builtin tool for plugin authors to provide a more "clear" and user-friendly plugin interface (and to create repeatable mappings with repeat.vim!). All of the functions of mkdx are mapped using <Plug> mappings. To disable a <Plug> mapping, first find it here or at: :h mkdx-plugs.

Say you want to disable the behaviour for toggling the next checkbox state. The corresponding <Plug> is called <Plug>(mkdx-checkbox-next-n). To disable it, add the following to your .vimrc:

When your vim has('job') or has('nvim'), mkdx will look for a grep program, the following are recognized:

The listed programs are searched in order, if a program is found, it will be used in various different places. This will prevent your editor from freezing and it'll be blazing fast compared to the builtin Vimscript fallbacks.

This section aims to answer some frequently(-ish) asked questions about mkdx!

E121 Undefined variable: g:mkdx#settings

This error comes up after you've added a setting such as: let = ' ' directly in your vimrc. This unfortunately is not possible, settings must be defined "long-form" like so:

let g:mkdx#settings = {
\ 'map': { 'prefix': ' ' }
\ }

The primary reason being that mkdx uses any g:mkdx#settings hash defined in your vimrc to override the defaults. These defaults are not defined straight from the start but merged after the vimrc has loaded.

There is no help for mkdx

There could be various reasons why helptags don't exist, from what I understand using Vim's native "pack" feature does not seem to auto-generate helptags, to fix this you can always run :helptags ALL.
