Rego Playground

Set the Rego version

Specify the Rego version for the module.

v0 is the default, which is the syntax enforced pre-OPA v1.0.

v1 is the Rego syntax enforced by OPA v1.0.

Strict

When enabled, the Rego compiler has an expanded set of constraints, which will be treated as errors when violated. E.g. duplicate imports, unused local variable assignments, shadowing of reserved 'input' and 'data' keywords, and use of some deprecated built-in functions.

Coverage

Coverage explains which statements were evaluated. Red expressions were never evaluated. Red rule heads were never defined. Green expressions were evaluated at least once. Green rule heads were defined at least once.

Built-in Error Behaviour

By default, built-in function errors are ignored, results will be from non-erroring code paths.

If Strict is selected, execution will exit early when the first built-in function error is encountered. If Show All is selected, all built-in errors from all code paths will be returned as an errors.

Live Linting

By default, linting is performed as you type. Disable this to only lint on evaluation.
