Summary

This PR refactors how the options of the linter are parsed/deserialized and passed to the actual linter.

Before, the serialization was done only when the rule was called, which caused various problems:

  • the parsing and deserialisation of the options of the rules were done inside the rule;
  • we had to pass a partial stringified JSON of the configuration. When this is parsed, the diagnostics were all wrong because we don't have the original configuration anymore;
  • we couldn't create a decent JSON schema of the options of the configuration;

With this PR, we now serialize all the options early when we parse and deserialize the configuration. The options are passed to the analyzer as a Box<dyn Any>, and then we do a downcast when needed. This is safe to do because the AnalyzerOptions are mandatory to pass, and the 'static restriction is always met.

In order to achieve this result, I had to add more restrictions to Rule::Options, such as Default and Clone.

Plus, I refactored the shape of the options of useExhaustiveDependencies and useHookAtTopLevel. The previous version didn't work out very well with Bpaf, and it was difficult to understand the numbers. With this new version, we can also document the value of the fields when we emit the JSON schema of the configuration.

Considering that these two rules are still under nursery, I'd say we don't need to create a migration for that, although I will create a changelog line with a hint of how to move to the new version of the configuration.

Test Plan

  • added some new test cases for the new configuration;
  • changed how we pass and test the configuration in the testing suite of rome_js_analyzer. Now we pass a full-fledged rome.json file, so we can use utility functions that we use in rome_service;
  • the tests of the current rules should still pass;

Changelog

  • The PR requires a changelog line

Documentation

  • The PR requires documentation
  • I will create a new PR to update the documentation

@nikeee you recently changed the CI output, I believe we forgot to add newlines to the output. Would you be available to do a follow-up PR to fix it?
