Feature Request: Options and Parameters Expressed as Environment Variables

[osterman]

what

• Allow any option or parameter to be optionally expressed as an environment variable like in variant1

why

• so we can set the base path of our configurations without needing to pass the parameter every time (kind of like the way variant2 uses the VARIANT_DIR), we want to set our own CONFIG_DIR which corresponds to the --config-dir parameter.

[osterman]

Actually, this should just work:

option "config-dir" {
  default     = coalesce(getenv("CONFIG_DIR"), "./stacks")
  description = "Stacks config directory"
  type        = string
}
