# Input file with one project name per line.
# Output: Orgfile to be pasted into Spacemacs org-table, to prioritise projects
# Makes for a less visually distracting environment to think about these projects

# rhellcheck disable=SC2162 # read without -r will mangle backslashes - Here as example of shellcheck-ignore

# TODOs:
# Insert marker in inputfile when interrupting the script before going through the whole inputfile. Would this marker have to be ignored by the script too?
# Autocomplete words on tag-page
# Remove outputfile if it's empty - They're often created during testing, and are tedious to remove by hand, but I'd rather do that than lose data

# MAYBE:
# Keep character limit in mind(?) Not that important. Better be expressive than caring that much about the length. Display number of characters while typing?
# If answer to a different one is "skip", skip just that column
# Options? Well. What options would I want?
# Sorts tags alphabetically?
# Calculates scores? (Would be a double thing though. Here and in Spacemacs. If in this script too: Sort by score)

# WON'T:
# Separate output into functions. From http://mywiki.wooledge.org/BashWeaknesses on 29aug2019: "There's no way to tell a function the name of a variable where you want it to put its output" - So yes: *Can* be done, but probably, sadly, shouldn't.
# Highlights tags I've already written - #bash says ~impossible
