Regal v0.6.0 released

[anderseknert]

Regal, the linter for Rego, just had a new release published: v0.6.0 🥳

Since there’s been a few more unannounced releases published this summer, here’s a list of some recent additions and improvements:

• Six new linter rules!
  • non-raw-regex-pattern for flagging regex patterns not using raw string literals
  • custom-in-construct for detecting custom "in" functions, i.e. where iteration is used instead of the in keyword
  • custom-has-key-construct for detecting custom "has_key" functions, where the use of in and object.keys should now be preferred
  • invalid-metadata-attribute for flagging unknown attributes in metadata annotations
  • detached-metadata (style violation) for detecting metadata annotations not directly attached to the code they annotate
  • no-whitespace-comment (style violation) for comments not starting with a whitespace
• Many improvements for creating custom rules, such as a regal new rule command for quickly creating template policy for new rules (custom or built-in ones). Also reworked the docs on this based on user feedback in order to improve the custom rule development experience. Regal will now additionally take the schema of the AST into account when doing type checking, so typos in e.g. input attribute names will now be caught at compile time.
• Configuration options for ignoring files (by name or pattern), either entirely or for specific rules only, so that it’s now possible to e.g. allow print calls in _test.rego files, but not anywhere else.
• Pre-commit hooks
