How I get the directory name up level?

[weyderfs]

How can I get the name of the directory up the level where my terragrunt.hcl is?

Example

• project-name/
  • sqs/
    • terragrunt.hcl

In this context bellow I need to get project-name, I've tried the followings functions without success:

• ${basename(${get_terragrunt_dir()}../)}
• basename(${get_terragrunt_dir()}../)
• ${basename(get_terragrunt_dir())../}
• "${run_cmd("ls -l ../../ | grep '^d' | awk -F' ' '{print $11}'')}" (In this context the problem is about the double quotes 😅)
• dirname("../../")
• basename("../../")

Maybe using the relative path + trimprefix, but I dont know how to combine and use them 😞 .

Hi,
depends on how the repository is organized - if project-name is also root of git repository, can be used get_repo_root() function:

locals {
  root_dir = run_cmd("echo", "${basename(get_repo_root())}")
}

https://terragrunt.gruntwork.io/docs/reference/built-in-functions/#get_repo_root

If this is not the case, and is only 2 levels of hierarchy, can be combined get_terragrunt_dir and dirname:

locals {
  path = "${get_terragrunt_dir()}/../.."
  root_dir = "${dirname(local.path)}"
}

Since concatenation is not working, additional strings can be added through variables

@denis256 thanks for help, In my case I use the second example because project-name not is the root. but now is showing the _ full path_ and not only de project-name folder.
I'm trying to adapt your example with trimprefix or other method, but if you know something will help me.

My adaptation:

locals {
  path = "${path_relative_to_include()}/../.."
  root_dir = run_cmd("echo", "${dirname(local.path)}")
  name = trimprefix("${local.root_dir}", "../..")
}
terraform {
  source = [...]
}

input = {
   name = local.name
   [...]
}

include {
  path = find_in_parent_folders()
}

The output:

Unsupported operator; Bitwise operators are not supported. Did you mean boolean OR ("||")?, and 7 other diagnostic(s)
ERRO[0000] Unable to determine underlying exit code, so Terragrunt will exit with error code 1

Try this:

locals {
  parent = "${get_terragrunt_dir()}/../"
  name = basename(dirname(local.parent))
}

input = {
   name = local.name
}

I will do more tests, but at first your example solve to me.
