## Installation
-If you use [Pathogen](http://www.vim.org/scripts/script.php?script_id=2332)(and you should), do this:
+If you use [Vundle](https://github.com/gmarik/vundle), add the following line to your `~/.vimrc`:
+
+```vim
+Plugin 'godlygeek/tabular'
+Plugin 'plasticboy/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:
- $ 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, download the [tarball](https://github.com/plasticboy/vim-markdown/archive/master.tar.gz) and do this:
+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/plasticboy/vim-markdown.git
+cd vim-markdown
+sudo make install
+vim-addon-manager install markdown
+```
- $ cd ~/.vim
- $ tar --strip=1 -zxf vim-markdown-master.tar.gz
+If you are not using any package manager, download the [tarball](https://github.com/plasticboy/vim-markdown/archive/master.tar.gz) and do this:
+
+```sh
+cd ~/.vim
+tar --strip=1 -zxf vim-markdown-master.tar.gz
+```
## Options
-**Disable Folding**
+### Disable Folding
+
+Add the following line to your `.vimrc` to disable the folding configuration:
+
+```vim
+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.
+
+```vim
+set [no]foldenable
+```
+
+### Change fold style
+
+To fold in a style like [python-mode](https://github.com/klen/python-mode), add the following to your `.vimrc`:
+
+```vim
+let g:vim_markdown_folding_style_pythonic = 1
+```
+
+Level 1 heading which is served as a document title is not folded.
+`g:vim_markdown_folding_level` setting is not active with this fold style.
+
+### Set header folding level
+
+Folding level is a number between 1 and 6. By default, if not specified, it is set to 1.
+
+```vim
+let g:vim_markdown_folding_level = 6
+```
+
+Tip: it can be changed on the fly with:
+
+```vim
+:let g:vim_markdown_folding_level = 1
+:edit
+```
+
+### Disable Default Key Mappings
+
+Add the following line to your `.vimrc` to disable default key mappings:
+
+```vim
+let g:vim_markdown_no_default_key_mappings = 1
+```
+
+You can also map them by yourself with `<Plug>` mappings.
+
+### 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.
+
+```vim
+let g:vim_markdown_toc_autofit = 1
+```
+
+### 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:
+
+```vim
+let g:vim_markdown_emphasis_multiline = 0
+```
+
+### 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.
+
+```vim
+set conceallevel=2
+```
+
+To disable conceal regardless of `conceallevel` setting, add the following to your `.vimrc`:
+
+```vim
+let g:vim_markdown_conceal = 0
+```
+
+### 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:
-Add the following line to your `.vimrc` to disable folding.
+```vim
+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']`.
+
+### Syntax extensions
+
+The following options control which syntax extensions will be turned on. They are off by default.
+
+#### LaTeX math
+
+Used as `$x^2$`, `$$x^2$$`, escapable as `\$x\$` and `\$\$x\$\$`.
```vim
-let g:vim_markdown_folding_disabled=1
+let g:vim_markdown_math = 1
```
-**Set Initial Foldlevel**
+#### YAML Front Matter
-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.
+Highlight YAML front matter as used by Jekyll or [Hugo](https://gohugo.io/content/front-matter/).
```vim
-let g:vim_markdown_initial_foldlevel=1
+let g:vim_markdown_frontmatter = 1
```
+#### TOML Front Matter
+
+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).
+
+```vim
+let g:vim_markdown_toml_frontmatter = 1
+```
+
+#### JSON Front Matter
+
+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).
+
+```vim
+let g:vim_markdown_json_frontmatter = 1
+```
+
+### 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:
+
+```vim
+let g:vim_markdown_new_list_item_indent = 2
+```
+
+
## Mappings
The following work on normal and visual modes:
-- `]]`: go to next header.
-- `[[`: go to previous header. Contrast with `]c`.
-- `][`: go to next sibling header if any.
-- `[]`: go to previous sibling header if any.
-- `]c`: go to Current header.
-- `]u`: go to parent header (Up).
+- `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`: 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`.
