cue eval

CUE v0.18.0

evaluate and print a configuration

Usage

cue eval [flags] [inputs]

eval evaluates, validates, and prints a configuration.

Printing is skipped if validation fails.

Input arguments can be CUE packages, CUE files, non-CUE files, or some combinations of those. See "cue help inputs" for more detail.

The --expression flag is used to evaluate an expression within the configuration file, instead of the entire configuration file itself.

Examples:

  $ cat <<EOF > foo.cue
  a: ["a", "b", "c"]
  EOF

  $ cue eval foo.cue -e a[0] -e a[2]
  "a"
  "c"
