Support for -var or -var-file arguments

[fogers]

we have value of variable which we pass from gitlab secrets and running tftree it requires it and tftree fails.

➜  git: ✗ tftree

Hi @fogers777, thanks for coming forward!

This is already possible, although I admit it should be documented. My bad.

Terraform supports setting variables in the environment. For example, to set the foo variable to bar:

TF_VAR_foo=bar tftree

Similarly, you can set flags for specific commands. To use the -var-file flag:

TF_CLI_ARGS_plan="-var-file=production.tfvars" tftree

The complete list of available environment variables is in Terraform's documentation here: https://developer.hashicorp.com/terraform/cli/config/environment-variables

I hope this solves your issue. Let me know if it does 🙂
