# Markdown Vim Mode
+[![Build Status](https://travis-ci.org/plasticboy/vim-markdown.svg)](https://travis-ci.org/plasticboy/vim-markdown)
+
Syntax highlighting, matching rules and mappings for [the original Markdown](http://daringfireball.net/projects/markdown/) and extensions.
## Installation
If you use [Vundle](https://github.com/gmarik/vundle), add the following line to your `~/.vimrc`:
- Bundle 'plasticboy/vim-markdown'
+```vim
+Plugin 'godlygeek/tabular'
+Plugin 'plasticboy/vim-markdown'
+```
+
+The `tabular` plugin must come *before* `vim-markdown`.
-And then run inside Vim:
+Then run inside Vim:
- :so ~/.vimrc
- :BundleInstall
+```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 mkd
+```
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
+```
## Options
-**Disable Folding**
+### Disable Folding
-Add the following line to your `.vimrc` to disable folding.
+Add the following line to your `.vimrc` to disable folding configuration.
```vim
let g:vim_markdown_folding_disabled=1
```
-**Set Initial Foldlevel**
+This option only controls vim_markdown's folding configuration. To enable/disable folding use Vim's folding configuration.
+
+```vim
+set [no]foldenable
+```
+
+### Set Initial Foldlevel
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.
let g:vim_markdown_initial_foldlevel=1
```
-**Disable Default Key Mappings**
+### Disable Default Key Mappings
-Add the following line to your `.vimrc` to disable default key mappings. You can map them by yourself with `<Plug>` mappings
+Add the following line to your `.vimrc` to disable default key mappings. You can map them by yourself with `<Plug>` mappings.
```vim
-let g:markdown_no_default_key_mappings=1
+let g:vim_markdown_no_default_key_mappings=1
+```
+
+### 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_math=1
+```
+
+#### YAML frontmatter
+
+Highlight YAML frontmatter as used by Jekyll:
+
+```vim
+let g:vim_markdown_frontmatter=1
```
## Mappings
- `]c`: go to Current header. `<Plug>(Markdown_MoveToCurHeader)`
- `]u`: go to parent header (Up). `<Plug>(Markdown_MoveToParentHeader)`
+## Commands
+
+- `: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-styleguide/#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`.
