Remove nested blocks

[mhennecke]

Consider following input:

test.hcl:

b1 {
  b2 l1 {
  }
}

Get nested block - works as expected

$ cat test.hcl | hcledit block get b1.b2.l1
b2 l1 {
}

Removal of nested block

Expected output:

b1 {
}

Actual output:

b1 {
  b2 l1 {
  }
}

Issue is present for single and multiple nested blocks. Use Case: Removal of all terraform.before_hook.* and terraform.after_hook.* in a terragrunt configuration before running it in automation in order to prevent execution of scripts on CI/CD agent host.

I tried to add the findLongestMatchingBlocks to unformattedBlockRemoveFilter and got the matching block. However, I would need a hint on how to remove those longest matching blocks from the resulting file: https://github.com/minamijoyo/hcledit/blob/397e5f46bda35b45501b36b841afd8b9d683a0f4/editor/filter_block_remove.go#L47

@mhennecke Thank you for reporting this!

It should work as you expect, but it seems not. I think we cannot reuse the findLongestMatchingBlocks method as it is because removing a block needs a body which the block belongs to.
