Convert markdown links to html with Pandoc

Question

In my new project I have multiple markdown files which are linked to each other. These links refer to the original .md files.

Example: File README.md

... 1. [Development documentation](Development.md) 1. [User documentation](Usage.md) ... 

If I convert these files with Pandoc, e.g. to html files, all links are still pointing to the original .md file. What I'm looking for is a way to convert also the link type, which means that output files should refer to the output file type such as HTML, PDF, TeX etc. Is there a way to convert the internal link type with Pandoc?

I use this to convert the files:

pandoc -f markdown -t html5 input.md -o output.html 

Answer 1

Example with the built-in Lua filters:

# links-to-html.lua function Link(el)   el.target = string.gsub(el.target, "%.md", ".html")   return el end 

Then:

pandoc -f markdown -t html5 input.md -o output.html --lua-filter=links-to-html.lua 

Answer 2

You can create a filter that checks every link element and--if the url ends with .md--replaces it with .html.

Example with Python, using the panflute package:

import panflute as pf  def action(elem, doc):     if isinstance(elem, pf.Link) and elem.url.endswith('.md'):         elem.url = elem.url[:-3] + '.html'         return elem  if __name__ == '__main__':     pf.run_filter(action)
