module Text.Pandoc.Util.Filter

-- | converts Attributes to String for usage in HTML
--   
--   Also converts <tt>width=xxx</tt> and <tt>height=xxx</tt> to the
--   corresponding style-attributes
attToString :: Attr -> String

-- | helper function for <a>attToString</a>, but can also be used if you
--   want to extract styles from kv-pair
convertToStyle :: [String] -> [(String, String)] -> [(String, String)]

-- | revealjs has some special attributes that has to be passed to the
--   html, but Pandoc only allows <tt>key=value</tt>-attributes, so we have
--   to abuse <tt>.class</tt> to rewrite them.
--   
--   The classes that get rewritten are listed here.
--   
--   You probably want <a>classToRevealAttr</a>, as that is a wrapper for
--   splitting the class-attribute
revealjsSpecialAttrs :: [String]

-- | HTML allows for some attributes (i.e. autoplay) for which revealjs
--   offers a special version (i.e. only autoplaying on active slide).
--   These are the things that get rewritten
revealjsRewriteAttr :: [String] -> [String]

-- | revealjs has some special attributes that has to be passed to the
--   html, but Pandoc only allows <tt>key=value</tt>-attributes, so we have
--   to abuse <tt>.class</tt> to rewrite them.
--   
--   This is a wrapper-function which just splits the list into real
--   classes and <a>revealjsSpecialAttrs</a>
classToRevealAttr :: [String] -> ([String], [String])

-- | small wrapper around <tt>RawInline (Format "html")</tt> as this is
--   less line-noise in the filters and the intent is more clear.
toHtml :: String -> Inline

-- | small wrapper around <tt>Raw (Format "html")</tt> as this is less
--   line-noise in the filters and the intent is more clear.
toBlockHtml :: String -> Block

-- | adds a given String to the list if not in there; Does nothing if the
--   given String is already present.
addToAtt :: Eq a => a -> [a] -> [a]

-- | adds given String to List of key-value-pairs (like in <a>Attr</a>) in
--   the "style"-Key.
--   
--   Useful when trying to add CSS-styles directly to (generated) elements
addToStyle :: String -> [(String, String)] -> [(String, String)]


-- | Conversion of lvl-x-headings to x-column-layouts in HTML especially
--   for use in revealjs-slides
module Text.Pandoc.Util.Filter.Cols

-- | This filter makes multi-column-layouts out of lvl-x-headings
--   
--   Syntax is
--   
--   <pre>
--   ## a b
--   </pre>
--   
--   yielding a 2-column-layout with aspects a:b i.e. 1:1 for 50/50-layout
--   or 8:2 for 80/20 layout
--   
--   currently works for 2 and 3-columns, but extension is
--   straight-forward.
--   
--   If you need multiple Block-Elements inside one column, just wrap them
--   with a <tt>&lt;div&gt;</tt>:
--   
--   <pre>
--   ## 2 5
--   
--   &lt;div&gt;
--   multiple things
--   ```
--   foo
--   ```
--    
--   &lt;/div&gt;
--   
--   second column here with only 1 element.
--   </pre>
cols :: [Block] -> [Block]

module Text.Pandoc.Util.Filter.Media

-- | main media-plugin.
--   
--   Will convert the following syntax
--   
--   <pre>
--   ![](foo.aac){#audio}
--   ![](foo.mp4){#video}
--   ![](foo.png){#img}
--   ![](foo.svg){#svg}
--   ![](foo.html){#demo}
--   </pre>
--   
--   HTML-id's maybe ommitted if the file-extension is in whitelist.
--   
--   If a type is detected by extension a custom id (not matching the
--   extension) will be preserved.

module Text.Pandoc.Util.Filter.Styling

-- | Block-Styling
--   
--   Special cases captured:
--   
--   <ul>
--   <li>#col turns a div into a floating-div for multiple columns</li>
--   <li>CodeBlock gets attributes <tt>data-trim</tt> and
--   <tt>data-noescape</tt> automatically</li>
--   <li>.fragment and .frame work properly on divs</li>
--   </ul>
styling :: Block -> IO [Block]

-- | Inline-Styling
--   
--   Special cases captured:
--   
--   <ul>
--   <li>.fragment and .frame work properly on spans</li>
--   <li>.vspace inside span adds a vertical space with
--   <tt>height=xxx</tt></li>
--   <li>.hspace inside span adds a horizontal space with
--   <tt>width=xxx</tt></li>
--   </ul>
