Clean up tests containing unnecessary `cwd:` tokens (#9692) # Description The working directory doesn't have to be set for those tests (or would be the default anyways). When appropriate also remove calls to the `pipeline()` function. In most places kept the diff minimal and only removed the superfluous part to not pollute the blame view. With simpler tests also simplified things to make them more readable overall (this included removal of the raw string literal). Work for #8670 2023-07-17 18:43:51 +02:00			`use nu_test_support::nu;`
Fix unexpected flattening of data by par-each (Issue #8497) (#9007) # Description Previously, `par-each` acted like a `flatmap`: first mapping the data, then applying a `flatten`. This is unlike `each`, which just maps the data. Now `par-each` works like `each` in this regard, leaving nested data unflattened. Fixes #8497 # User-Facing Changes Previously: `[1 2 3] \| par-each {\|e\| [$e, $e] }` --> `[1,1,2,2,3,3]` Now: `[1 2 3] \| par-each {\|e\| [$e, $e] }` --> `[[1,1],[2,2],[3,3]]` # Tests This adds one test that verifies the lack of flattening for `par-each`. 2023-04-26 23:27:27 +02:00
