Description

This issue tracks development of plugin configuration for the linter. This is merely about extending our configuration format and settings so that plugins can be configured. The actual loading or executing of plugins is considered out of scope here.

To see how this issue fits into our plugin efforts, please look at the overview here: #2463

Tasks

• Add a linter.rulePlugins section to the configuration.
  • In a first iteration, this can probably be a single array of strings, each being the path to an individual plugin file.
• Implement plugin resolution.
  • We probably want to use oxc_resolver so that package names can be used in place of direct paths to the plugins.
• Extend configuration to include rule options.
  • We can probably take inspiration from how rule options are configured for built-in rules.
  • Keep in mind that the JSON schema cannot verify options for plugins, unlike built-in rules where we know the types.

Discussion

• Do we want support for individual plugins that enable multiple rules? It seems unnecessary for a first release, but there might be advantages to supporting this. A downside would be the configuration would become more complex if we need to be able to enable/disable rules per plugin.
