# The following script selects a note using bemenu.
# It takes a single argument: the note directory.
# It then presents all *.md files within the directory.
# It outputs the file path of the slected note.
#
# bemenue supports priting the search query regradless of whether it matches a
# note or not. this allows editing nonexistent files, or in another sense
# creating a note if it doesn't already exist (assuming the program consuming
# the path supports opening files and creating them later, i.e. most editors)

# error on missing variables and failed piplines
