The files were formatted according to the `.editorconfig` file and with
the formatter from [this](1) repo, as it's the only one that fully
understands all keys in the `.editorconfig` file.
The formatting was chosen in this special (and honestly unconventional)
way because moving code from lua to nix is now easier, as the syntax is
nearly identical in some places.
It is very common, that I'm in a situation with bad contrast on the
laptop screen (for example when in direct sunlight). To remedy the fact,
that I can't see the colours in these situations, the plus and minus
marks were added.
