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 `` 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 (i.e., 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`. +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. + +```vim +set conceallevel=2 +``` + +To disable conceal regardless of `conceallevel` setting, add the following to your `.vimrc`: + +```vim +let g:vim_markdown_conceal = 0 +``` + +To disable math conceal with LaTeX math syntax enabled, add the following to your `.vimrc`: + +```vim +let g:tex_conceal = "" +let g:vim_markdown_math = 1 +``` + +### 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: + +```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']`. + +### Follow named anchors + +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: + +```vim +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. -Add the following line to your `.vimrc` to disable folding. +Default is `0`. ```vim -let g:vim_markdown_folding_disabled=1 +let g:vim_markdown_anchorexpr = "'<<'.v:anchor.'>>'" ``` -**Set Initial Foldlevel** +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 `<>`. -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. +Default is `''`. + +### 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/). + +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 +``` + +#### Strikethrough + +Strikethrough uses two tildes. `~~Scratch this.~~` + +```vim +let g:vim_markdown_strikethrough = 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 +``` + +### Do not require .md extensions for Markdown links + +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: ```vim -let g:vim_markdown_initial_foldlevel=1 +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. -**Disable Default Key Mappings** +### Auto-write when following link -Add the following line to your `.vimrc` to disable default key mappings. You can map them by yourself with `` mappings. +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: ```vim -let g:vim_markdown_no_default_key_mappings=1 +let g:vim_markdown_autowrite = 1 +``` + +### Change default file extension + +If you would like to use a file extension other than `.md` you may do so using the `vim_markdown_auto_extension_ext` variable: + +```vim +let g:vim_markdown_auto_extension_ext = 'txt' +``` + +### Do not automatically insert bulletpoints + +Automatically inserting bulletpoints can lead to problems when wrapping text +(see issue #232 for details), so it can be disabled: + +```vim +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: + +```vim +let g:vim_markdown_new_list_item_indent = 0 +``` + +### Change how to open new files + +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: + +```vim +let g:vim_markdown_edit_url_in = 'tab' ``` ## Mappings The following work on normal and visual modes: -- `]]`: go to next header. `(Markdown_MoveToNextHeader)` -- `[[`: go to previous header. Contrast with `]c`. `(Markdown_MoveToPreviousHeader)` -- `][`: go to next sibling header if any. `(Markdown_MoveToNextSiblingHeader)` -- `[]`: go to previous sibling header if any. `(Markdown_MoveToPreviousSiblingHeader)` -- `]c`: go to Current header. `(Markdown_MoveToCurHeader)` -- `]u`: go to parent header (Up). `(Markdown_MoveToParentHeader)` +- `gx`: open the link under the cursor in the same browser as the standard `gx` command. `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 + + + ^ ^ ^ + 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. `Markdown_EditUrlUnderCursor` + + The rules for the cursor position are the same as the `gx` command. + +- `]]`: go to next header. `Markdown_MoveToNextHeader` + +- `[[`: go to previous header. Contrast with `]c`. `Markdown_MoveToPreviousHeader` + +- `][`: go to next sibling header if any. `Markdown_MoveToNextSiblingHeader` + +- `[]`: go to previous sibling header if any. `Markdown_MoveToPreviousSiblingHeader` + +- `]c`: go to Current header. `Markdown_MoveToCurHeader` + +- `]u`: go to parent header (Up). `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 Markdown_MoveToParentHeader + +To disable a map use: + + map Markdown_MoveToParentHeader ## Commands -The following commands currently only work for atx style headers (`#`). Pull request are welcome to extend them to Setext style 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. -- `:Toc`: create a quickfix vertical window navigable table of contents with the headers. + 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 `` 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`. ## Credits
