+# vim-pandoc-syntax
+
+[![Vint](https://github.com/vim-pandoc/vim-pandoc-syntax/workflows/Vint/badge.svg)](https://github.com/vim-pandoc/vim-pandoc-syntax/actions?workflow=Vint)
+
+Standalone pandoc syntax module, to be used alongside
+[vim-pandoc](http://github.com/vim-pandoc/vim-pandoc).
+
+Forked from the version provided by `fmoralesc/vim-pantondoc`, in turn taken
+from `vim-pandoc/vim-pandoc`.
+
+## Requirements
+
+* A vim version with `+conceal`
+* [vim-pandoc](http://github.com/vim-pandoc/vim-pandoc), to set the
+  `pandoc` filetype (otherwise you'll have to set it up yourself).
+
+## Installation
+
+The repository follows the usual bundle structure, so it's easy to install it
+using [pathogen](https://github.com/tpope/vim-pathogen),
+[Vundle](https://github.com/gmarik/vundle) or NeoBundle.
+
+For Vundle users, it should be enough to add
+
+    Plugin 'vim-pandoc/vim-pandoc-syntax'
+
+to `.vimrc`, and then run `:PluginInstall`.
+
+For those who need it, a tarball is available from
+[here](https://github.com/vim-pandoc/vim-pandoc-syntax/archive/master.zip).
+
+### Standalone
+
+If you want to use `vim-pandoc-syntax` without vim-pandoc, you'll need to tell
+Vim to load it for certain files. Just add something like this to your vimrc:
+
+~~~ vim
+augroup pandoc_syntax
+    au! BufNewFile,BufFilePre,BufRead *.md set filetype=markdown.pandoc
+augroup END
+~~~
+
+For vimwiki users, use
+
+~~~ vim
+augroup pandoc_syntax
+  autocmd! FileType vimwiki set syntax=markdown.pandoc
+augroup END
+~~~
+
+
+## Features
+
+* Supports most (if not all) pandoc's markdown features, including tables,
+  delimited codeblocks, references, etc.
+* Can handle multiple embedded languages (LaTeX, YAML headers, many languages
+  in delimited codeblocks). Some commands are provided to help with this (see
+  `:help pandoc-syntax-commands`)
+* Pretty display using `conceal` (optional).
+* Configurable (see `:help pandoc-syntax-configuration` for an overview of the
+  options).

+*vim-pandoc-syntax*
+*pandoc-syntax*
+
+OVERVIEW
+
+vim-pandoc-syntax is a standalone syntax file for highlighting pandoc flavored
+markdown documents, to be used alongside vim-pandoc (see |pandoc|). It is
+based on the version once provided by vim-pandoc-legacy, which it obsoletes.
+
+The project resides at http://www.github.com/vim-pandoc/vim-pandoc-syntax. You
+are welcome to help, suggest ideas, report bugs or contribute code.
+
+ 
+CONFIGURATION				       *vim-pandoc-syntax-configuration*
+
++ *g:pandoc#syntax#conceal#use*
+  Use |conceal| for pretty highlighting. Default is 1 for vim version > 7.3
+
++ *g:pandoc#syntax#conceal#blacklist* A list of rules |conceal| should not be
+  used with. Works as a blacklist, and defaults to [] (use conceal everywhere).
+
+  This is a list of the rules wich can be used here:
+
+  - titleblock 
+  - image
+  - block
+  - subscript
+  - superscript
+  - strikeout
+  - atx
+  - codeblock_start
+  - codeblock_delim
+  - footnote
+  - definition
+  - list
+  - newline
+  - dashes
+  - ellipses
+  - quotes
+  - inlinecode
+  - inlinemath
+
+  To review what are the rules for, look for the call to |s:WithConceal| in
+  syntax/pandoc.vim that takes the corresponding  rulename as first argument.
+
++ *g:pandoc#syntax#conceal#cchar_overrides*
+  A dictionary of what characters should be used in conceal rules. These
+  override the defaults (see those in |s:cchars|). For example, if you prefer
+  to mark footnotes with the `*` symbol:
+
+      let g:pandoc#syntax#conceal#cchar_overrides = {"footnote" : "*"}
+
++ *g:pandoc#syntax#conceal#urls*
+  Conceal the urls in links.
+
++ *g:pandoc#syntax#codeblocks#ignore*
+  Prevent highlighting specific codeblock types so that they remain Normal.
+  Codeblock types include 'definition' for codeblocks inside definition blocks
+  and 'delimited' for delimited codeblocks. Default = []
+
++ *g:pandoc#syntax#codeblocks#embeds#use*
+  Use embedded highlighting for delimited codeblocks where a language is
+  specified. Default = 1
+
++ *g:pandoc#syntax#codeblocks#embeds#langs*
+  For what languages and using what syntax files to highlight embeds. This is
+  a list of language names. When the language pandoc and vim use don't match,
+  you can use the "PANDOC=VIM" syntax. For example:
+
+      let g:pandoc#syntax#codeblocks#embeds#langs = ["ruby",
+      "literatehaskell=lhaskell", "bash=sh"]
+
++ *g:pandoc#syntax#style#emphases*
+  Use italics and strong in emphases. Default = 1
+  0 will add "block" to |g:pandoc#syntax#conceal#blacklist|, because otherwise
+  you couldn't tell where the styles are applied.
+
++ *g:pandoc#syntax#style#underline_special*
+  Underline subscript, superscript and strikeout text styles. Default = 1
+
++ *g:pandoc#syntax#style#use_definition_lists*
+  Detect and highlight definition lists. Disabling this can improve
+  performance. Default = 1 (i.e., enabled by default)
+
+COMMANDS                                            *pandoc-syntax-commands*
+
++ *:PandocHighlight* LANG
+
+  Enable embedded highlighting for language LANG in codeblocks. Uses the
+  syntax for items in |g:pandoc#syntax#codeblocks#embeds#langs|.
+
++ *:PandocUnhighlight* LANG
+
+  Disable embedded highlighting for language LANG in codeblocks.
+
+FUNCTIONS                                           *pandoc-syntax-functions*
+
++ *EnableEmbedsForCodeblocksWithLang(langname)*
+  As |:PandocHighlight|.
+
++ *DisableEmbedsForCodeblocksWithLang(langname)*
+  As |:PandocUnhighlight|.
+
++ *s:WithConceal(RULE_GROUP,RULE,CONCEAL_RULE)*
+  Executes a |:syntax| command RULE, which could incorporate conceal rules
+  (CONCEAL_RULE) if  conceals are enabled. The rule gets named RULE_GROUP,
+  as used in |g:pandoc#syntax#conceal#blacklist|.
+
+  For example, if conceals are enabled
+
+      call s:WithConceal("atx", 'syn match AtxStart /#/ contained
+          containedin=pandocAtxHeader', 'conceal cchar='.s:cchars["atx"])
+
+  will execute
+
+      syn match AtxStart /#/ contained containedin=pandocAtxHeader conceal cchar=§
+
+  and 
+
+      syn match AtxStart /#/ contained containedin=pandocAtxHeader 
+
+  otherwise.
+
+TODO
+
+This is a list of know stuff missing from the syntax file.
+
+   1. Highlight code within verbatim text when a language is specified in the attrib, 
+   like in
+
+          hey, `print 1 + 3`.{python} is no longer valid in python 3. 
+
+
+MISC
+
+The plugin sets a global variable, *g:vim_pandoc_syntax_exists* to indicate its
+existence. This is currently used by vim-pandoc to switch between syntax
+assisted and basic folding rules.
