Anyone know of a good markdown viewer that is formatted instead of showing the source with colors?

I'm using pandoc to convert it to groff and read it like a formatted man page, which is ok but not great as it loses some formatting.

  pandoc -s -f markdown -t man markdown.md | groff -T utf8 -man | less -R

Actually plain less works quite well when using filters:

  #!/bin/bash
  # ~/.lessfilter
  case $1 in
    *.md) view-md $1;;
    *.json) jq -C . $1;;
    *) pygmentize $1;;
  esac

Where view-md is just a thin wrapper around tty-markdown[1]:

  #!/usr/bin/env ruby
  
  require 'tty-markdown'
  
  puts TTY::Markdown.parse(ARGF.read, colors: 256)
