Learn more. 🧩 Analysis chain@o-l-a-v You are absolutely correct, and I apologize for my error. PowerShell arrays do indeed have the IndexOf() method available as an instance method. Your example perfectly demonstrates this: PS > $([string[]]('0','1','2')).IndexOf('1')
1 When working with an array of values, IndexOf can be used to find the position of the value in the array, and the [array]::IndexOf() method works well, but arrays also have IndexOf as an instance method.

I am concerned whether the sort is a stable sort algorithm for keys that are not present in the index list.
Could multiple executions yield different results?
Uh oh!

IMO there could and should be a check for keys we don't want to be present. Doesn't this exist already?
To make formatjson.ps1 safer we could do: If key is not present in the schema.json
Uh oh!

Does it? It will fail execution currently.

I was thinking more about that other parts of the validation should catch manifest errors before it gets to
formatjson.ps1
. Thus validating that the manifest doesn't contain invalid keys is a task thatformatjson.ps1
shouldn't try to solve.There was a problem hiding this comment.

Seems that's what the validator is for?
https://github.com/ScoopInstaller/Scoop/tree/master/supporting/validator
Thus I don't think the new function
Sort-ScoopManifestRootProperties
should have a lot of validation logic. It's a feature that it throws if manifest does not comply withschema.json

I added a check for parent keys not present in
schema.json
insideSort-ScoopManifestRootProperties
. Then users will get a better error message than what you posted in #6494 (comment).Uh oh!

Or we could write a warning, and just return the object as is / not try to sort the object at all. Instead of throwing.

Yes, thanks for reminding.
Totally agree. Great.
