#
# This script adds a "dg-publish: true" to all *.md files that don't have
# a "dg-publish: " defined in it's frontmatter.
#
# Consequences of this:
# - non versioned files won't be affected (e.g.: gitignored files)
# - files without any frontmatter will have one with "dg-publish: true"
# - files with a "dg-publish: " (any value) in its frontmatter won't be touched
#
# WARNING: understand what this script does before using it!!!
#
# This script was created to be used in my Obsidian vault and to publish my
# digital garden using this awesome plugin:
# https://github.com/oleeskild/obsidian-digital-garden
