# CONTRIBUTING
These contributing guidelines were accepted rather late in the history of this plugin, after much code had already been written.
If you find any existing behavior which does not conform to these guidelines, please correct it and send a pull request.
## General Rules
Every non local identifier must start with `g:vim_markdown_`.
## Documentation
Every new feature must be documented under in the [README.md](README.md). Documentation must be written in [GFM](https://help.github.com/articles/github-flavored-markdown) since GitHub itself is the primary to HTML converter used. In particular, remember that GFM adds line breaks at single newlines, so just forget about the 70 characters wide rule.
Vim help file [doc/vim-markdown.txt](doc/vim-markdown.txt) will be generated from [README.md](README.md) by `make doc` using [vim-tools](https://github.com/xolox/vim-tools).
## Markdown Flavors
There are many flavors of markdown, each one with an unique feature set. This plugin uses the following strategy to deal with all those flavors:
- Features from the [original markdown](http://daringfireball.net/projects/markdown/syntax) are turned on by default. They may not even have an option that turns them off.
- Features from other markdown flavors *must* have an option that turns them on or off. If the feature is common enough across multiple versions of markdown, it may be turned on by default. This shall be decided by the community when the merge request is done.
- If possible, cite the exact point in the documentation of the flavor where a feature is specified. If the feature is not documented, you may also reference the source code itself of the implementation. This way, people who do not know that flavor can check if your implementation is correct.
- Do not use the name of a flavor for a feature that is used across multiple flavors. Instead, create a separate flavor option, that automatically sets each feature.
For example, fenced code blocks (putting code between pairs of three backticks) is not part of the original markdown, but is supported by [GFM](https://help.github.com/articles/github-flavored-markdown#fenced-code-blocks) and [Jekyll](http://jekyllrb.com/docs/configuration/).
Therefore, instead of creating an option `g:vim_markdown_gfm_fenced_code_block`, and an option `g:vim_markdown_jekyll_fenced_code_block`, create a single option `g:vim_markdown_fenced_code_block`.
Next, if there are many more than one Jekyll feature options, create a `g:vim_markdown_jekyll` option that turns them all on at once.
## Style
When choosing between multiple valid Markdown syntaxes, the default behavior must be that specified at: <https://cirosantilli.com/markdown-style-guide>
If you wish to have a behavior that differs from that style guide, add an option to turn it on or off, and leave it off by default.
## Tests
All new features must have unit tests.
## Issues
Issues are tracked within GitHub.
When reporting issues, your report is more effective if you include a minimal example file that reproduces the problem. Try to trim out as much as possible, until you have the smallest possible file that still reproduces the issue. Paste the example inline into your issue report, quoted using four spaces at the beginning of each line, like this example from issue [#189](https://github.com/preservim/vim-markdown/issues/189):
```
Minimal example:
```
=
```
bad!
```

# Vim Markdown
[![Vint](https://github.com/preservim/vim-markdown/workflows/Vint/badge.svg)](https://github.com/preservim/vim-markdown/actions?workflow=Vint)
[![Vader](https://github.com/preservim/vim-markdown/workflows/Vader/badge.svg)](https://github.com/preservim/vim-markdown/actions?workflow=Vader)
Syntax highlighting, matching rules and mappings for [the original Markdown](http://daringfireball.net/projects/markdown/) and extensions.
1. [Installation](#installation)
1. [Basic usage](#basic-usage)
1. [Options](#options)
1. [Mappings](#mappings)
1. [Commands](#commands)
1. [Credits](#credits)
1. [License](#license)
## Installation
If you use [Vundle](https://github.com/gmarik/vundle), add the following lines to your `~/.vimrc`:
```vim
Plugin 'godlygeek/tabular'
Plugin 'preservim/vim-markdown'
```
The `tabular` plugin must come *before* `vim-markdown`.
Then run inside Vim:
```vim
:so ~/.vimrc
:PluginInstall
```
If you use [Pathogen](https://github.com/tpope/vim-pathogen), do this:
```sh
cd ~/.vim/bundle
git clone https://github.com/preservim/vim-markdown.git
```
To install without Pathogen using the Debian [vim-addon-manager](http://packages.qa.debian.org/v/vim-addon-manager.html), do this:
```sh
git clone https://github.com/preservim/vim-markdown.git
cd vim-markdown
sudo make install
vim-addon-manager install markdown
```
If you are using a package manager with semver support (like [lazy.nvim](https://github.com/folke/lazy.nvim)) make sure you are following the master branch (see https://github.com/preservim/vim-markdown/issues/616).
If you are not using any package manager, download the [tarball](https://github.com/preservim/vim-markdown/archive/master.tar.gz) and do this:
```sh
cd ~/.vim
tar --strip=1 -zxf vim-markdown-master.tar.gz
```
## Basic usage
### Folding
Folding is enabled for headers by default.
The following commands are useful to open and close folds:
- `zr`: reduces fold level throughout the buffer
- `zR`: opens all folds
- `zm`: increases fold level throughout the buffer
- `zM`: folds everything all the way
- `za`: toggle a fold your cursor is on
- `zA`: toggle a fold your cursor is on recursively
- `zo`: open a fold your cursor is on
- `zO`: open a fold your cursor is on recursively
- `zc`: close a fold your cursor is on
- `zC`: close a fold your cursor is on recursively
[Options](#options) are available to disable folding or change folding style.
Try `:help fold-expr` and `:help fold-commands` for details.
### 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](#options) are available to disable or change concealing.
Try `:help concealcursor` and `:help conceallevel` for details.
## Options
### Disable Folding
- `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
### Change fold style
- `g:vim_markdown_folding_style_pythonic`
To fold in a style like [python-mode](https://github.com/klen/python-mode), 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`
To prevent foldtext from being set add the following to your `.vimrc`:
let g:vim_markdown_override_foldtext = 0
### Set header 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
### Disable 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.
### Enable TOC window auto-fit
- `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
### Text emphasis restriction to single-lines
- `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
### Syntax Concealing
- `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`
Disabling conceal for code fences requires an additional setting:
let g:vim_markdown_conceal_code_blocks = 0
### Fenced code block 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']`.
### Follow named anchors
- `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`
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 `''`.
### Syntax extensions
The following options control which syntax extensions will be turned on. They are off by default.
#### LaTeX math
- `g:vim_markdown_math`
Used as `$x^2$`, `$$x^2$$`, escapable as `\$x\$` and `\$\$x\$\$`.
let g:vim_markdown_math = 1
#### YAML Front Matter
- `g:vim_markdown_frontmatter`
Highlight YAML front matter as used by Jekyll or [Hugo](https://gohugo.io/content/front-matter/).
let g:vim_markdown_frontmatter = 1
#### TOML Front Matter
- `g:vim_markdown_toml_frontmatter`
Highlight TOML front matter as used by [Hugo](https://gohugo.io/content/front-matter/).
let g:vim_markdown_toml_frontmatter = 1
#### JSON Front Matter
- `g:vim_markdown_json_frontmatter`
Highlight JSON front matter as used by [Hugo](https://gohugo.io/content/front-matter/).
let g:vim_markdown_json_frontmatter = 1
#### Strikethrough
- `g:vim_markdown_strikethrough`
Strikethrough uses two tildes. `~~Scratch this.~~`
let g:vim_markdown_strikethrough = 1
### Adjust 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
### Do not require .md extensions for Markdown links
- `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.
### Auto-write when following link
- `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
### Change default file extension
- `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'
### Do not automatically insert bulletpoints
- `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`
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'
### Borderless tables
- `g:vim_markdown_borderless_table`
Add support for borderless tables, such as:
```
header 1|header 2
--|--
data 1|data 2
```
if set to `1`:
let g:vim_markdown_borderless_table = 1
the table would be formatted as usual:
```
| header 1 | header 2 |
|----------|----------|
| data 1 | data 2 |
```
## Mappings
The following work on normal and visual modes:
- `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.
- `ge`: open the link under the cursor in Vim for editing. Useful for relative markdown links. Falls back to `gf` with force editing, if not on a markdown link. `<Plug>Markdown_EditUrlUnderCursor`
The rules for the cursor position are the same as the `gx` command.
- `]]`: go to next header. `<Plug>Markdown_MoveToNextHeader`
- `[[`: go to previous header. Contrast with `]h`. `<Plug>Markdown_MoveToPreviousHeader`
- `][`: go to next sibling header if any. `<Plug>Markdown_MoveToNextSiblingHeader`
- `[]`: go to previous sibling header if any. `<Plug>Markdown_MoveToPreviousSiblingHeader`
- `]h`: go to Current header. `<Plug>Markdown_MoveToCurHeader`
- `]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`:
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`: Analogous to `:HeaderDecrease`, but increase levels instead.
- `: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`: Format the table under the cursor [like this](http://www.cirosantilli.com/markdown-style-guide/#tables).
Requires [Tabular](https://github.com/godlygeek/tabular).
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`: 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`: Same as `:Toc` but in an horizontal window.
- `:Toct`: Same as `:Toc` but in a new tab.
- `:Tocv`: Same as `:Toc` for symmetry with `:Toch` and `:Tocv`.
- `:InsertToc`: Insert table of contents at the current line.
An optional argument can be used to specify how many levels of headers to display in the table of content, e.g., to display up to and including `h3`, use `:InsertToc 3`.
- `:InsertNToc`: Same as `:InsertToc`, but the format of `h2` headers in the table of contents is a numbered list, rather than a bulleted list.

===============================================================================
*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 'preservim/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/preservim/vim-markdown.git
<
To install without Pathogen using the Debian vim-addon-manager [4], do this:
>
git clone https://github.com/preservim/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': toggle a fold your cursor is on
*vim-markdown-zA*
- 'zA': toggle a fold your cursor is on recursively
*vim-markdown-zo*
- 'zo': open a fold your cursor is on
*vim-markdown-zO*
- 'zO': 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
<
-------------------------------------------------------------------------------
*vim-markdown-change-how-to-open-new-files*
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'
<
-------------------------------------------------------------------------------
*vim-markdown-support-borderless-tables*
Support borderless tables ~
*g:vim_markdown_borderless_table*
- 'g:vim_markdown_borderless_table'
Add support for borderless tables, such as:
>
header 1|header 2
--|--
data 1|data 2
<
if set to 1:
>
let g:vim_markdown_borderless_table = 1
<
the table would be formatted as usual:
>
| header 1 | header 2 |
|----------|----------|
| data 1 | data 2 |
<
===============================================================================
*vim-markdown-mappings*
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 ']h'.
'<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-]h*
- ']h': 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
<
===============================================================================
*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'.
