                                                    *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 line 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-options*
Options ~

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

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 ~

To fold in a style like python-mode [6], add the following to your '.vimrc':
>
  let g:vim_markdown_folding_style_pythonic = 1
<
-------------------------------------------------------------------------------
                                        *vim-markdown-set-header-folding-level*
Set header 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 ~

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 ~

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 ~

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 (ie,
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 ~

Concealing is set for some syntax.

For example, conceal '[link text](link url)' as just 'link text'.

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
<
-------------------------------------------------------------------------------
                                     *vim-markdown-fenced-code-block-languages*
Fenced code block 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-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 ~

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 ~

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 ~

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 ~

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-adjust-new-list-item-indent*
Adjust 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-mappings*
Mappings ~

The following work on normal and visual modes:

                                                                           *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.

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

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

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

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

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

                                                                           *]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
<

                                                        *vim-markdown-commands*
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'.
