You could also do $direnv | values | length but I think is-empty works ok too.

does anyone know how this script is supposed to run actually ?
it seems to work, but I'm not sure why or how.
direnv export json never seems to return anything
and also the $direnv variable can be empty or not depending at what times you run it.

@happysalada direnv export doesn't show anything when all exported variables are already captured and made available to the current shell. So maybe this is your case?

Alright but my problem is that direnv is always of length one, whether its empty or not. It makes me wonder what the original intent of the code was
