mdpreview

#!/bin/bash
#
#  mdpreview - preview a markdown file
#
#  Idea from:
#    https://ubuntuincident.wordpress.com/2011/05/05/readme-markdown-on-github/
#
#  This does not handle the Github variations documented at:
#    https://help.github.com/articles/github-flavored-markdown
#  You may want to try using a gist to get a more accurate preview.
#    https://gist.github.com/
#
#  To-do: add an option to keep running in the background, monitoring the
#  input file, and, when it changes, regenerate the HTML file and have
#  the browser reload it.

# Should be be using xdg-open instead?
# Does sensible-browser background automatically when no browser is running?
