$ cue help vet
vet validates CUE and other data files

By default it will only validate if there are no errors.
The -c validates that all regular fields are concrete.

Checking non-CUE files

Vet can also check non-CUE files. The following file formats are
currently supported:

  Format       Extensions
	JSON       .json .jsonl .ndjson
	YAML       .yaml .yml
	TEXT       .txt  (validate a single string value)

To activate this mode, the non-cue files must be explicitly mentioned on the
command line. There must also be at least one CUE file to hold the constraints.

In this mode, each file will be verified against a CUE constraint. If the files
contain multiple objects (such as using --- in YAML), they will all be verified

By default, each file is checked against the root of the loaded CUE files.
The -d can be used to only verify files against the result of an expression
evaluated within the CUE files. This can be useful if the CUE files contain
a set of definitions to pick from.


  # Check files against a CUE file:
  cue vet foo.cue foo.yaml

  # Check files against a particular expression
  cue vet foo.cue translations/*.yaml -d '#Translation'

More than one expression may be given using multiple -d flags. Each non-CUE
file must match all expression values.
