## Installation
-If you use [Vundle](https://github.com/gmarik/vundle), add the following line to your `~/.vimrc`:
+If you use [Vundle](https://github.com/gmarik/vundle), add the following lines to your `~/.vimrc`:
- Bundle 'plasticboy/vim-markdown'
+```vim
+Plugin 'godlygeek/tabular'
+Plugin 'plasticboy/vim-markdown'
+```
-And then run inside Vim:
+The `tabular` plugin must come *before* `vim-markdown`.
- :so ~/.vimrc
- :BundleInstall
+Then run inside Vim:
+
+```vim
+:so ~/.vimrc
+:PluginInstall
+```
If you use [Pathogen](https://github.com/tpope/vim-pathogen), do this:
- $ cd ~/.vim/bundle
- $ git clone https://github.com/plasticboy/vim-markdown.git
+```sh
+cd ~/.vim/bundle
+git clone https://github.com/plasticboy/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:
- $ git clone https://github.com/plasticboy/vim-markdown.git
- $ cd vim-markdown
- $ sudo make install
- $ vim-addon-manager install mkd
+```sh
+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](https://github.com/plasticboy/vim-markdown/archive/master.tar.gz) and do this:
- $ cd ~/.vim
- $ tar --strip=1 -zxf vim-markdown-master.tar.gz
+```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`: open a fold your cursor is on
+- `zA`: 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**
+### Disable Folding
-Add the following line to your `.vimrc` to disable folding.
+- `g:vim_markdown_folding_disabled`
-```vim
-let g:vim_markdown_folding_disabled=1
-```
+ Add the following line to your `.vimrc` to disable the folding configuration:
-**Set Initial Foldlevel**
+ let g:vim_markdown_folding_disabled = 1
-Add the following line to your `.vimrc` to set the initial foldlevel. This option defaults to 0 (i.e. all folds are closed) and is ignored if folding is disabled.
+ This option only controls Vim Markdown specific folding configuration.
-```vim
-let g:vim_markdown_initial_foldlevel=1
-```
+ To enable/disable folding use Vim's standard folding configuration.
-**Disable Default Key Mappings**
+ set [no]foldenable
-Add the following line to your `.vimrc` to disable default key mappings. You can map them by yourself with `<Plug>` mappings.
+### Change fold style
-```vim
-let g:vim_markdown_no_default_key_mappings=1
-```
+- `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/).
+
+ TOML syntax highlight requires [vim-toml](https://github.com/cespare/vim-toml).
+
+ 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/).
+
+ JSON syntax highlight requires [vim-json](https://github.com/elzr/vim-json).
+
+ 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'
## Mappings
The following work on normal and visual modes:
-- `]]`: 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`: go to Current header. `<Plug>(Markdown_MoveToCurHeader)`
-- `]u`: go to parent header (Up). `<Plug>(Markdown_MoveToParentHeader)`
+- `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. `<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 `]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`: 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
-- `:Toc`: create a quickfix vertical window navigable table of contents with the headers.
+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`.
+- `: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`.
