Support Tofu backends with variables

[sarg3nt]

OpenTofu v1.8.0 supports early variable/locals evaluation which allows for variables in backends. These do not appear to work in tftui.

Here are the commands I've tried.

tftui -e tofu -f ../deployments/k8s-common-dev.tfvars -f ../deployments/k8s-dev.tfvars
# and
tftui -e tofu -n -f ../deployments/k8s-common-dev.tfvars -f ../deployments/k8s-dev.tfvars   

And the error output

Error: Unable to compute static value

  on backend.tf line 4, in terraform:
   4:   backend "remote" {

backend.remote depends on var.tofu_backend which is not available

Config of the backend

terraform {
  backend "remote" {
    hostname     = var.tofu_backend.hostname
    organization = var.tofu_backend.organization
    token        = var.tofu_backend.token
    workspaces {
      prefix = "cluster_"
    }
  }
}

Are there any plans to support Tofu and backends with vars?

What you might need to do to fix it is pass the vars to every command. i.e. they are needed in tf init, tf show, tf state * etc. We had to rework some of our automation to get it all to work.
