mp3md

DIR     = %(content/music/)
MP3DIR  = %(audio)

$md = <<~'MD'
  +++
  title = '@@title'
  date = 2024-02-28T18:04:10+01:00
  draft = false
  +++

  (two curly braces)< audio src="@@title.mp3" >(closing braces)
MD

def create_md(title)
  path = '%s%s.md' % [DIR, title]
  File.write(path, $md.gsub(/@@title/, title)) unless File.exist? path
end

Dir.glob(format('%s%s/*.mp3', DIR, MP3DIR)).each do |file|
  create_md(File.basename(file.delete_suffix('.mp3')))
end

I use this to create an md-file for every mp3-file found in subfolder. (closing braces) is replaced with ‘}}’ and (two curly braces) is replaced with ‘{{’

inserting shortcode from layouts (a simple audio tag)

Todo: use create-time for mp3 as date in heading.
