## Installation
If you use [Vundle](https://github.com/gmarik/vundle), add the following line to your `~/.vimrc`:
git clone https://github.com/plasticboy/vim-markdown.git
cd vim-markdown
sudo make install
-vim-addon-manager install mkd
+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:
## 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
+```
+
+### 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
-Add the following line to your `.vimrc` to disable folding.
+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_folding_disabled=1
+let g:vim_markdown_emphasis_multiline = 0
```
-**Set Initial Foldlevel**
+### Syntax Concealing
+
+Concealing is set for some syntax.
-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.
+For example, conceal `[link text](link url)` as just `link text`.
+
+To enable/disable conceal use Vim's standard conceal configuration.
```vim
-let g:vim_markdown_initial_foldlevel=1
+set conceallevel=2
```
-**Disable Default Key Mappings**
+### 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 Front Matter
+
+Highlight YAML front matter as used by Jekyll or [Hugo](https://gohugo.io/content/front-matter/).
+
+```vim
+let g:vim_markdown_frontmatter = 1
+```
+
+#### TOML Front Matter
+
+Highlight TOML front matter as used by [Hugo](https://gohugo.io/content/front-matter/).
-Add the following line to your `.vimrc` to disable default key mappings. You can map them by yourself with `<Plug>` mappings.
+TOML syntax highlight requires [vim-toml](https://github.com/cespare/vim-toml).
```vim
-let g:vim_markdown_no_default_key_mappings=1
+let g:vim_markdown_toml_frontmatter = 1
```
-**Syntax extensions**
+#### JSON Front Matter
-The following options control which syntax extensions will be turned on.
+Highlight JSON front matter as used by [Hugo](https://gohugo.io/content/front-matter/).
-LaTeX math: `$ $`, `$$ $$`, escapable as `\$ \$` and `\$\$ \$\$`:
+JSON syntax highlight requires [vim-json](https://github.com/elzr/vim-json).
```vim
-let g:vim_markdown_math=1
+let g:vim_markdown_json_frontmatter = 1
```
+
## 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.
+
+- `]]`: 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
-- `:HeaderDecrease`:
+The following requires `:filetype plugin on`.
+
+- `:HeaderDecrease`:
Decrease level of all headers in buffer: `h2` to `h1`, `h3` to `h2`, etc.
For simplicity of implementation, Setex headers are converted to Atx.
-- `:HeaderIncrease`: Analogous to `:HeaderDecrease`, but increase levels instead.
+- `: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`: Format the table under the cursor [like this](http://www.cirosantilli.com/markdown-styleguide/#tables).
+- `: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.
+- `: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.
+- `:Toch`: Same as `:Toc` but in an horizontal window.
-- `:Toct`: Same as `:Toc` but in a new tab.
+- `:Toct`: Same as `:Toc` but in a new tab.
-- `:Tocv`: Same as `:Toc` for symmetry with `:Toch` and `Tocv`.
+- `:Tocv`: Same as `:Toc` for symmetry with `:Toch` and `Tocv`.
