Direnv env var additions, overrides, and removals

I use direnv to overlay folder specific configurations in projects when I cd into them.

My default way to set it up is a

dotenv

VAR1=hey

Then you run

❯ direnv allow
direnv: loading ~/dev/thought-eddies/src/content/til/direnv/.envrc
direnv: export +VAR1

I was used to always seeing +s but today I saw ~.

I learned ~ is a modification and - is a removal, so with a setup like the following (on my machine), the following file setup elicits all three.

dotenv
unset PAGER

VAR1=hey
EDITOR=code

❯ direnv allow
direnv: loading ~/dev/thought-eddies/src/content/til/direnv/.envrc
direnv: export +VAR1 -PAGER ~EDITOR
