Installation

Download the filters from: https://github.com/mittelmark/pandoc-filters/archive/refs/heads/main.zip and place them on your harddisk. If you process your document you specify the filters like this:

pandoc input.md -o output.html --lua-filter /path/to/filter-python.py -s 

Alternatively you can place the files into your pandoc user directory which you can find out by writing pandoc -v in your terminal. If you place your Lua files into this folder you can use the Lua filters without using the file path like this:

pandoc input.md -o output.html --lua-filter filter-code-title.lua -s
