feat(linter): fill schemas `DummyRuleMap` with built-in rules by Sysix · Pull Request #22288 · oxc-project/oxc

Sysix · 2026-05-10T14:03:43Z

This PR enhances Oxlint configuration schema fidelity by expanding DummyRuleMap to explicitly list all built-in rules as schema properties (improving editor autocomplete), while adding markdown-renderer filtering to avoid generating massive documentation sections for rules.

Pull request overview

This PR enhances Oxlint configuration schema fidelity by expanding DummyRuleMap to explicitly list all built-in rules as schema properties (improving editor autocomplete), while adding markdown-renderer filtering to avoid generating massive documentation sections for rules.

Changes:

Implement a custom JsonSchema for DummyRuleMap that enumerates built-in rules as properties (while keeping additionalProperties for extensibility).
Add property_filters support to the schema-to-markdown renderer and apply it to hide nested rules.* / overrides[n].rules.* entries from the generated docs.
Regenerate schema artifacts: website schema snapshot, npm-published schema JSON, and the generated TS config types.

File	Description
`crates/oxc_linter/src/config/rules.rs`	Custom `JsonSchema` for `DummyRuleMap` that emits built-in rule names as schema properties.
`tasks/website_common/src/schema_markdown.rs`	Add property filtering to prevent rendering filtered subtrees in schema markdown output.
`tasks/website_linter/src/json_schema.rs`	Apply property filters so `rules` sections don’t expand into thousands of rule entries in docs.
`npm/oxlint/configuration_schema.json`	Updated generated schema JSON to include `DummyRuleMap.properties` for built-in rules.
`tasks/website_linter/src/snapshots/schema_json.snap`	Updated snapshot for the expanded schema output.
`apps/oxlint/src-js/package/config.generated.ts`	Updated generated TS types so `DummyRuleMap` includes built-in rule keys.
