@tznind We need to fix this in ocgv too. I haven't had a chance to look at your fix here closely, so I'm curious if you spent anytime on that?

Ah, no I did not look at the ocgv command. I did create a helper though shouldn't be too hard to port across. I can probably take a look at the weekend.

tznind · 2024-03-30T10:25:03Z

@tig I have looked into the ocgv implementation and do not think it will have the same issues that the tree view had (that this PR corrects).

ocgv uses GetFormatViewDefinitionForObject and CastObjectsToTableView to deal with the input PSObject directly while tree view involves itself quite heavily in 'Root object' being wrapped by the PSObject (e.g. to handle cases like directories etc).

Both of the below look like correct behaviours to me, see example json

$Values = @'
[
  {
    "id": 1,
    "name": "John",
    "age": 30,
    "city": "New York",
	"people":
	[
		{
			"name": "Alice"
		},
		{
			"name": "Frank"
		}
	]
  },
  {
    "id": 2,
    "name": "Alice",
    "age": 25,
    "city": "Los Angeles"
  },
  {
    "id": 3,
    "name": "Bob",
    "age": 35,
    "city": "Chicago"
  }
]

Here is an example with Get-ChildItem with FileInfo and DirectoryInfo.

[...]

I am not sure I fully understand the question. But I think the answer is yes.

The default operating proceedure for the tree view is to look for a real .NET object and enumerate its properties as leaves/branches. For example PS D:\Repos\GraphicalTools> Get-ChildItem | shot

piping get children to tree view

Note that in the case of DirectoryInfo the sub folders are also listed after properties.

However calling gm would flatten the tree which would not be helpful, so calling Get-ChildItem | gm | where MemberType -notin property,method | shot just lists the member definitions:

piping gm output is not particularly helpful
