Output:

Arguably, it should only be printed if directory is non-empty, happy to make that change if you'd like that.

[lkysow]

I think it's okay to always print the directory because it would be weird if you had

/
  main.tf
  subproject/
    main.tf

And it only printed the directory for subproject.

The directory is relative and if it's in the root, it will just be .. Let's detect that and use / in that case.

[tfheen]

Updated to make . print as /.

Suggested change

	if directory == "." {
	// Since "." looks weird, replace it with "/" to make it clear this is the root.
	if directory == "." {

[lkysow]

Just one small change please. Then looks good.

[lkysow]

I realized I could make the edit myself, thanks!

[tfheen]
