Release Notes

StyraInc/regal (StyraInc/regal)

v0.18.0

Compare Source

Only a week after v0.17.0, this release comes a little earlier than planned as we found a few issues in the VS Code OPA extension integration that we wanted to address as soon as possible. Nothing serious, but having that extension provide a great Regal experience feels important enough for us to warrant an earlier v0.18.0 release. That's not all there is to this release though, as we have both a new linter rule as well as a bunch of fixes included here. Enjoy!

New rule: ignored-import

Category: imports

Use of explicit references (like data.user.roles) that could instead point to an existing import will now be flagged in order to ensure that the imports a user has declared aren't ignored later in the policy.

For more information, see the docs on ignored-import.

Improvements

• The external-reference rule is now much better at detecting external references in function bodies.
• The rule-shadows-builtin now flags shadowed namespaces (like http) and not just shadowing of the full name (like http.send)
• The use-in-operator rule now also takes = into account (previous only == would be checked for)
• The unused-return-value rule was renamed unassigned-return-value to better reflect what the issue is

Bugs Fixed

• The only-scalars config option in prefer-value-in-head rule wasn't working — now it does!
• Fix false positive in prefer-some-in-iteration
