cue fix

CUE v0.18.0

rewrite packages to latest standards

Usage

cue fix [flags] [packages]

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.

Experiments

CUE experiments are features that are not yet part of the stable language but are being tested for future inclusion. Some of these may introduce backwards incompatible changes for which there is a cue fix. The --exp flag is used to change a file or package to use the new, experimental semantics. Experiments are enabled on a per-file basis.

For example, to enable the "explicitopen" experiment for all files in a package whose module is on a language version before v0.18.0, which is where that experiment became stable, you would run:

	cue fix . --exp=explicitopen

For this to succeed, your current language version must support the experiment. If an experiment has not yet been accepted for the current version, an @experiment attribute is added in each affected file to mark the transition as complete. An experiment which is already stable for that version needs no fix, as files use it without an attribute, and asking for one is an error.

The special value --exp=all enables all experimental features that apply to the current version.
