Had a conversation with Anton about __GIT_WORKING_DIR__ and found that can be used non-default config names in many subdirectories like

tflint --config other_config.hcl

https://github.com/terraform-linters/tflint/blob/master/docs/user-guide/config.md

So that PR break that and, also, decreases exciting functional.

Maybe, I will investigate GIT_DIR var in the future, as git native replacement for __GIT_WORKING_DIR__. If not - I will add __GIT_WORKING_DIR__ for all hooks

@MaxymVlasov GIT_DIR does not exist in many cases and for many users.

I use this hook in my .bash_profile:

precmd() {
	GIT_REPO_DIR=$(git rev-parse --show-toplevel 2>/dev/null)
	if [[ -n "$GIT_REPO_DIR" ]]; then
	  export GIT_REPO_DIR="$GIT_REPO_DIR"
	fi
}

I use this hook in my .bash_profile

jfyi, it should be safe to replace it with a oneliner:

precmd() {
        GIT_REPO_DIR=$(git rev-parse --show-toplevel 2>/dev/null) && export GIT_REPO_DIR || unset GIT_REPO_DIR
}
