$ cue help fix
Fix finds CUE programs that use old syntax and old APIs and rewrites them to use newer ones.
After you update to a new CUE release, fix helps make the necessary changes
to your program.

Without any packages, fix applies to all files within a module.

Usage:
  cue fix [packages] [flags]

Flags:
  -f, --force   rewrite even when there are errors

Global Flags:
  -E, --all-errors   print all available errors
  -i, --ignore       proceed in the presence of errors
  -s, --simplify     simplify output
      --trace        trace computation
  -v, --verbose      print information about progress
