                                                    *vim-markdown-introduction*
Introduction ~

Syntax highlighting, matching rules and mappings for the original Markdown [1]
and extensions.

===============================================================================
                                                    *vim-markdown-installation*
Installation ~

If you use Vundle [2], add the following lines to your '~/.vimrc':
>
  Plugin 'godlygeek/tabular'
  Plugin 'plasticboy/vim-markdown'
<
The 'tabular' plugin must come _before_ 'vim-markdown'.

Then run inside Vim:
>
  :so ~/.vimrc
  :PluginInstall
<
If you use Pathogen [3], do this:
>
  cd ~/.vim/bundle
  git clone https://github.com/plasticboy/vim-markdown.git
<
To install without Pathogen using the Debian vim-addon-manager [4], do this:
>
  git clone https://github.com/plasticboy/vim-markdown.git
  cd vim-markdown
  sudo make install
  vim-addon-manager install markdown
<
If you are not using any package manager, download the tarball [5] and do this:
>
  cd ~/.vim
  tar --strip=1 -zxf vim-markdown-master.tar.gz
<

                                                     *vim-markdown-basic-usage*
Basic usage ~

-------------------------------------------------------------------------------
                                                         *vim-markdown-folding*
Folding ~

Folding is enabled for headers by default.

The following commands are useful to open and close folds:

                                                              *vim-markdown-zr*
- 'zr': reduces fold level throughout the buffer
                                                              *vim-markdown-zR*
- 'zR': opens all folds
                                                              *vim-markdown-zm*
- 'zm': increases fold level throughout the buffer
                                                              *vim-markdown-zM*
- 'zM': folds everything all the way
                                                              *vim-markdown-za*
- 'za': open a fold your cursor is on
                                                              *vim-markdown-zA*
- 'zA': open a fold your cursor is on recursively
                                                              *vim-markdown-zc*
- 'zc': close a fold your cursor is on
                                                              *vim-markdown-zC*
- 'zC': close a fold your cursor is on recursively

Options are available to disable folding or change folding style.

Try ':help fold-expr' and ':help fold-commands' for details.

-------------------------------------------------------------------------------
                                                      *vim-markdown-concealing*
Concealing ~

Concealing is set for some syntax such as bold, italic, code block and link.

Concealing lets you conceal text with other text. The actual source text is not
modified. If you put your cursor on the concealed line, the conceal goes away.

Options are available to disable or change concealing.

Try ':help concealcursor' and ':help conceallevel' for details.

===============================================================================
                                                         *vim-markdown-options*
Options ~

-------------------------------------------------------------------------------
                                                 *vim-markdown-disable-folding*
Disable Folding ~

                                              *g:vim_markdown_folding_disabled*
- 'g:vim_markdown_folding_disabled'

  Add the following line to your '.vimrc' to disable the folding
  configuration:
>
  let g:vim_markdown_folding_disabled = 1
<
  This option only controls Vim Markdown specific folding configuration.

  To enable/disable folding use Vim's standard folding configuration.
>
  set [no]foldenable
<
-------------------------------------------------------------------------------
                                               *vim-markdown-change-fold-style*
Change fold style ~

                                        *g:vim_markdown_folding_style_pythonic*
- 'g:vim_markdown_folding_style_pythonic'

  To fold in a style like python-mode [6], add the following to your
  '.vimrc':
>
  let g:vim_markdown_folding_style_pythonic = 1
<
  'g:vim_markdown_folding_level' setting (default 1) is set to 'foldlevel'.
  Thus level 1 heading which is served as a document title is expanded by
  default.

                                             *g:vim_markdown_override_foldtext*
- 'g:vim_markdown_override_foldtext'

  To prevent foldtext from being set add the following to your '.vimrc':
>
  let g:vim_markdown_override_foldtext = 0
<
-------------------------------------------------------------------------------
                                        *vim-markdown-set-header-folding-level*
Set header folding level ~

                                                 *g:vim_markdown_folding_level*
- 'g:vim_markdown_folding_level'

  Folding level is a number between 1 and 6. By default, if not specified, it
  is set to 1.
>
  let g:vim_markdown_folding_level = 6
<
  Tip: it can be changed on the fly with:
>
  :let g:vim_markdown_folding_level = 1
  :edit
<
-------------------------------------------------------------------------------
                                    *vim-markdown-disable-default-key-mappings*
Disable Default Key Mappings ~

                                       *g:vim_markdown_no_default_key_mappings*
- 'g:vim_markdown_no_default_key_mappings'

  Add the following line to your '.vimrc' to disable default key mappings:
>
  let g:vim_markdown_no_default_key_mappings = 1
<
  You can also map them by yourself with '<Plug>' mappings.

-------------------------------------------------------------------------------
                                      *vim-markdown-enable-toc-window-auto-fit*
Enable TOC window auto-fit ~

                                                   *g:vim_markdown_toc_autofit*
- 'g:vim_markdown_toc_autofit'

  Allow for the TOC window to auto-fit when it's possible for it to shrink.
  It never increases its default size (half screen), it only shrinks.
>
  let g:vim_markdown_toc_autofit = 1
<
-------------------------------------------------------------------------------
                       *vim-markdown-text-emphasis-restriction-to-single-lines*
Text emphasis restriction to single-lines ~

                                            *g:vim_markdown_emphasis_multiline*
- 'g:vim_markdown_emphasis_multiline'

  By default text emphasis works across multiple lines until a closing token
  is found. However, it's possible to restrict text emphasis to a single line
  (i.e., for it to be applied a closing token must be found on the same
  line). To do so:
>
  let g:vim_markdown_emphasis_multiline = 0
<
-------------------------------------------------------------------------------
                                               *vim-markdown-syntax-concealing*
Syntax Concealing ~

                                                       *g:vim_markdown_conceal*
- 'g:vim_markdown_conceal'

  Concealing is set for some syntax.

  For example, conceal '[link text](link url)' as just 'link text'. Also,
  '_italic_' and '*italic*' will conceal to just _italic_. Similarly
  '__bold__', '**bold**', '___italic bold___', and '***italic bold***' will
  conceal to just **bold**, **bold**, **_italic bold_**, and **_italic
  bold_** respectively.

  To enable conceal use Vim's standard conceal configuration.
>
  set conceallevel=2
<
  To disable conceal regardless of 'conceallevel' setting, add the following
  to your '.vimrc':
>
  let g:vim_markdown_conceal = 0
<
  To disable math conceal with LaTeX math syntax enabled, add the following
  to your '.vimrc':
>
  let g:tex_conceal = ""
  let g:vim_markdown_math = 1
<
                                           *g:vim_markdown_conceal_code_blocks*
- 'g:vim_markdown_conceal_code_blocks'

  Disabling conceal for code fences requires an additional setting:
>
  let g:vim_markdown_conceal_code_blocks = 0
<
-------------------------------------------------------------------------------
                                     *vim-markdown-fenced-code-block-languages*
Fenced code block languages ~

                                              *g:vim_markdown_fenced_languages*
- 'g:vim_markdown_fenced_languages'

  You can use filetype name as fenced code block languages for syntax
  highlighting. If you want to use different name from filetype, you can add
  it in your '.vimrc' like so:
>
  let g:vim_markdown_fenced_languages = ['csharp=cs']
<
  This will cause the following to be highlighted using the 'cs' filetype
  syntax.
>
  ```csharp
  ...
  ```
<
  Default is "['c++=cpp', 'viml=vim', 'bash=sh', 'ini=dosini']".

-------------------------------------------------------------------------------
                                            *vim-markdown-follow-named-anchors*
Follow named anchors ~

                                                 *g:vim_markdown_follow_anchor*
- 'g:vim_markdown_follow_anchor'

  This feature allows the 'ge' command to follow named anchors in links of
  the form 'file#anchor' or just '#anchor', where file may omit the '.md'
  extension as usual. Two variables control its operation:
>
  let g:vim_markdown_follow_anchor = 1
<
  This tells vim-markdown whether to attempt to follow a named anchor in a
  link or not. When it is 1, and only if a link can be split in two parts by
  the pattern '#', then the first part is interpreted as the file and the
  second one as the named anchor. This also includes urls of the form
  '#anchor', for which the first part is considered empty, meaning that the
  target file is the current one. After the file is opened, the anchor will
  be searched.

  Default is '0'.

                                                    *g:vim_markdown_anchorexpr*
- 'g:vim_markdown_anchorexpr'
>
  let g:vim_markdown_anchorexpr = "'<<'.v:anchor.'>>'"
<
  This expression will be evaluated substituting 'v:anchor' with a quoted
  string that contains the anchor to visit. The result of the evaluation will
  become the real anchor to search in the target file. This is useful in
  order to convert anchors of the form, say, 'my-section-title' to searches
  of the form 'My Section Title' or '<<my-section-title>>'.

  Default is "''".

-------------------------------------------------------------------------------
                                               *vim-markdown-syntax-extensions*
Syntax extensions ~

The following options control which syntax extensions will be turned on. They
are off by default.

-------------------------------------------------------------------------------
                                                      *vim-markdown-latex-math*
LaTeX math ~

                                                          *g:vim_markdown_math*
- 'g:vim_markdown_math'

  Used as '$x^2$', '$$x^2$$', escapable as '\$x\$' and '\$\$x\$\$'.
>
  let g:vim_markdown_math = 1
<
-------------------------------------------------------------------------------
                                               *vim-markdown-yaml-front-matter*
YAML Front Matter ~

                                                   *g:vim_markdown_frontmatter*
- 'g:vim_markdown_frontmatter'

  Highlight YAML front matter as used by Jekyll or Hugo [7].
>
  let g:vim_markdown_frontmatter = 1
<
-------------------------------------------------------------------------------
                                               *vim-markdown-toml-front-matter*
TOML Front Matter ~

                                              *g:vim_markdown_toml_frontmatter*
- 'g:vim_markdown_toml_frontmatter'

  Highlight TOML front matter as used by Hugo [7].

  TOML syntax highlight requires vim-toml [8].
>
  let g:vim_markdown_toml_frontmatter = 1
<
-------------------------------------------------------------------------------
                                               *vim-markdown-json-front-matter*
JSON Front Matter ~

                                              *g:vim_markdown_json_frontmatter*
- 'g:vim_markdown_json_frontmatter'

  Highlight JSON front matter as used by Hugo [7].

  JSON syntax highlight requires vim-json [9].
>
  let g:vim_markdown_json_frontmatter = 1
<
-------------------------------------------------------------------------------
                                                   *vim-markdown-strikethrough*
Strikethrough ~

                                                 *g:vim_markdown_strikethrough*
- 'g:vim_markdown_strikethrough'

  Strikethrough uses two tildes. '~~Scratch this.~~'
>
  let g:vim_markdown_strikethrough = 1
<
-------------------------------------------------------------------------------
                                     *vim-markdown-adjust-new-list-item-indent*
Adjust new list item indent ~

                                          *g:vim_markdown_new_list_item_indent*
- 'g:vim_markdown_new_list_item_indent'

  You can adjust a new list indent. For example, you insert a single line
  like below:
>
  * item1
<
  Then if you type 'o' to insert new line in vim and type '* item2', the
  result will be:
>
  * item1
      * item2
<
  vim-markdown automatically insert the indent. By default, the number of
  spaces of indent is 4. If you'd like to change the number as 2, just write:
>
  let g:vim_markdown_new_list_item_indent = 2
<
-------------------------------------------------------------------------------
                *vim-markdown-do-not-require-.md-extensions-for-markdown-links*
Do not require .md extensions for Markdown links ~

                                     *g:vim_markdown_no_extensions_in_markdown*
- 'g:vim_markdown_no_extensions_in_markdown'

  If you want to have a link like this '[link text](link-url)' and follow it
  for editing in vim using the 'ge' command, but have it open the file "link-
  url.md" instead of the file "link-url", then use this option:
>
  let g:vim_markdown_no_extensions_in_markdown = 1
<
  This is super useful for GitLab and GitHub wiki repositories.

  Normal behaviour would be that vim-markup required you to do this '[link
  text](link-url.md)', but this is not how the Gitlab and GitHub wiki
  repositories work. So this option adds some consistency between the two.

-------------------------------------------------------------------------------
                                  *vim-markdown-auto-write-when-following-link*
Auto-write when following link ~

                                                     *g:vim_markdown_autowrite*
- 'g:vim_markdown_autowrite'

  If you follow a link like this '[link text](link-url)' using the 'ge'
  shortcut, this option will automatically save any edits you made before
  moving you:
>
  let g:vim_markdown_autowrite = 1
<
-------------------------------------------------------------------------------
                                   *vim-markdown-change-default-file-extension*
Change default file extension ~

                                            *g:vim_markdown_auto_extension_ext*
- 'g:vim_markdown_auto_extension_ext'

  If you would like to use a file extension other than '.md' you may do so
  using the 'vim_markdown_auto_extension_ext' variable:
>
  let g:vim_markdown_auto_extension_ext = 'txt'
<
-------------------------------------------------------------------------------
                        *vim-markdown-do-not-automatically-insert-bulletpoints*
Do not automatically insert bulletpoints ~

                                           *g:vim_markdown_auto_insert_bullets*
- 'g:vim_markdown_auto_insert_bullets'

  Automatically inserting bulletpoints can lead to problems when wrapping
  text (see issue #232 for details), so it can be disabled:
>
  let g:vim_markdown_auto_insert_bullets = 0

  In that case, you probably also want to set the new list item indent to 0
  as well, or you will have to remove an indent each time you add a new list
  item:
>
  let g:vim_markdown_new_list_item_indent = 0

Change how to open new files ~

                                                   *g:vim_markdown_edit_url_in*
- 'g:vim_markdown_edit_url_in'

  By default when following a link the target file will be opened in your
  current buffer. This behavior can change if you prefer using splits or tabs
  by using the 'vim_markdown_edit_url_in' variable. Possible values are
  'tab', 'vsplit', 'hsplit', 'current' opening in a new tab, vertical split,
  horizontal split, and current buffer respectively. Defaults to current
  buffer if not set:
>
  let g:vim_markdown_edit_url_in = 'tab'

Mappings ~

The following work on normal and visual modes:

                                                              *vim-markdown-gx*
- 'gx': open the link under the cursor in the same browser as the standard
  'gx' command. '<Plug>Markdown_OpenUrlUnderCursor'

  The standard 'gx' is extended by allowing you to put your cursor anywhere
  inside a link.

  For example, all the following cursor positions will work:
>
  [Example](http://example.com)
  ^  ^    ^^   ^       ^
  1  2    34   5       6

  <http://example.com>
  ^  ^               ^
  1  2               3
<
  Known limitation: does not work for links that span multiple lines.

                                                              *vim-markdown-ge*
- 'ge': open the link under the cursor in Vim for editing. Useful for
  relative markdown links. '<Plug>Markdown_EditUrlUnderCursor'

  The rules for the cursor position are the same as the 'gx' command.

                                                              *vim-markdown-]]*
- ']]': go to next header. '<Plug>Markdown_MoveToNextHeader'

                                                              *vim-markdown-[[*
- '[[': go to previous header. Contrast with ']c'.
  '<Plug>Markdown_MoveToPreviousHeader'

                                                              *vim-markdown-][*
- '][': go to next sibling header if any.
  '<Plug>Markdown_MoveToNextSiblingHeader'

                                                              *vim-markdown-[]*
- '[]': go to previous sibling header if any.
  '<Plug>Markdown_MoveToPreviousSiblingHeader'

                                                              *vim-markdown-]c*
- ']c': go to Current header. '<Plug>Markdown_MoveToCurHeader'

                                                              *vim-markdown-]u*
- ']u': go to parent header (Up). '<Plug>Markdown_MoveToParentHeader'

This plugin follows the recommended Vim plugin mapping interface, so to change
the map ']u' to 'asdf', add to your '.vimrc':
>
  map asdf <Plug>Markdown_MoveToParentHeader
<
To disable a map use:
>
  map <Plug> <Plug>Markdown_MoveToParentHeader
<

Commands ~

The following requires ':filetype plugin on'.

                                                              *:HeaderDecrease*
- ':HeaderDecrease':

  Decrease level of all headers in buffer: 'h2' to 'h1', 'h3' to 'h2', etc.

  If range is given, only operate in the range.

  If an 'h1' would be decreased, abort.

  For simplicity of implementation, Setex headers are converted to Atx.

                                                              *:HeaderIncrease*
- ':HeaderIncrease': Analogous to ':HeaderDecrease', but increase levels
  instead.

                                                                  *:SetexToAtx*
- ':SetexToAtx':

  Convert all Setex style headers in buffer to Atx.

  If a range is given, e.g. hit ':' from visual mode, only operate on the
  range.

                                                                 *:TableFormat*
- ':TableFormat': Format the table under the cursor like this [10].

  Requires Tabular [11].

  The input table _must_ already have a separator line as the second line of
  the table. That line only needs to contain the correct pipes '|', nothing
  else is required.

                                                                         *:Toc*
- ':Toc': create a quickfix vertical window navigable table of contents with
  the headers.

  Hit '<Enter>' on a line to jump to the corresponding line of the markdown
  file.

                                                                        *:Toch*
- ':Toch': Same as ':Toc' but in an horizontal window.

                                                                        *:Toct*
- ':Toct': Same as ':Toc' but in a new tab.

                                                                        *:Tocv*
- ':Tocv': Same as ':Toc' for symmetry with ':Toch' and ':Tocv'.
