Writing filters is easy: Pandoc basically converts the input document into a universal AST (json), and a filter is just any program that takes this json as an input and outputs a modified json AST.&lt;p&gt;I wrote a filter that automatically converts URL citstions in markdown to &amp;quot;real&amp;quot; citations in any style you want - very useful for writing papers without fighting with bibtex and managing bibliographies manually: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;phiresky&amp;#x2F;pandoc-url2cite&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;phiresky&amp;#x2F;pandoc-url2cite&lt;/a&gt;</text><parent_chain><item><author>cosmic_quanta</author><text>One thing I love about pandoc that I don&amp;#x27;t see mentioned here is the ability to apply filters to transform documents mid-conversion.&lt;p&gt;I&amp;#x27;m using Pandoc to write my PhD thesis at the moment, from Markdown source, using certain filters to &amp;quot;augment&amp;quot; what Markdown can do.
