Summary

adds the ignoreBooleanCoercion option to useNullishCoalescing, partially addressing #9232. this follows on from #9974 which added ignoreMixedLogicalExpressions.

when enabled, || and ||= are not reported if the value is boolean-coerced by an enclosing Boolean() call, since coalescing on falsy values is intentional in that spot. i kept the scope to just this one option so it stays easy to review. the remaining options from #9232 (ignorePrimitives, ignoreIfStatements) can come as separate PRs.

the detection mirrors how the merged mixed-logical code reads: a small typed helper that scans ancestors, skips parens and logical parents (both || and &&, since the coerced value still flows into the call), and then checks the first other ancestor is the argument of a Boolean() call.

Test Plan

the spec snapshots cover this, but if you want to check it by hand:

drop a biome.json enabling the rule and option:

{ "linter": { "rules": { "nursery": { "useNullishCoalescing": { "level": "error", "options": { "ignoreBooleanCoercion": true } } } } } }

make a test.ts:

declare const a: string | null;
declare const b: string;
declare function identity<T>(v: T): T;

const r1 = Boolean(a || b);        // quiet
const r2 = Boolean(a || b || b);   // quiet (chained)
const r3 = Boolean(b && (a || b)); // quiet (&& inside Boolean)
const r4 = a || b;                 // reports
const r5 = identity(a || b);       // reports (not a Boolean call)

run biome lint test.ts. only r4 and r5 should report.
flip the option to false and re-run. now r1, r2, r3 should report too.

things worth poking at for coverage:

||= inside Boolean() (e.g. Boolean(x ||= y)) should be quiet when the option is on
the non-Boolean callee (identity(...)) should still report, to confirm it's keyed on the Boolean name and not just "any call"
new Boolean(a || b) still reports. i think that's right since it constructs an object rather than coercing, but worth a sanity check

Docs

the option is documented in the rule's rustdoc with invalid/valid examples and validated by rules_check. no website PR needed while the rule is in nursery.

- suppresses || and ||= when the value is boolean-coerced by an enclosing Boolean() call - walks out through parens and logical parents, so chained and && cases inside Boolean() are covered too - partially addresses biomejs#9232, follows on from biomejs#9974

Walkthrough

This PR adds a new ignoreBooleanCoercion option to the useNullishCoalescing linter rule that suppresses || and ||= diagnostics when they appear inside a Boolean() call. Changes include the options schema definition, a new is_in_boolean_call_context helper to detect Boolean(...) context via AST traversal, early-exit guards in run_logical_or and run_logical_or_assignment handlers, comprehensive test fixtures for both enabled and disabled configurations, and release documentation.

Possibly related issues

#9842: Requests semantic resolution of the Boolean callee to distinguish global built-ins from shadowed identifiers, extending the detection logic introduced here.

Possibly related PRs

biomejs/biome#9248: Both modify nursery/useNullishCoalescing by adding different "ignore" options (ignoreBooleanCoercion vs ignoreTernaryTests) to suppress diagnostics in specific contexts.
biomejs/biome#9974: Uses the same option-gated early-exit pattern in run_logical_or for a different condition (ignoreMixedLogicalExpressions).

Previously it always used the default configuration resolution and reported the configuration as `Not set` when no `biome.json` existed in the working directory. - [#10763](biomejs/biome#10763) [`2c3e82d`](biomejs/biome@2c3e82d) Thanks [@Aqu1bp](https://github.com/Aqu1bp)! - Fixed [#10742](biomejs/biome#10742): [`noSolidDestructuredProps`](https://biomejs.dev/linter/rules/no-solid-destructured-props) now reports destructured props in Solid function components and JSX children. - [#10606](biomejs/biome#10606) [`a4cc4ab`](biomejs/biome@a4cc4ab) Thanks [@Mokto](https://github.com/Mokto)! - Fixed false positives in `noUnusedImports`, `noUnusedVariables`, and `useImportType` for Svelte components that use both a `<script module>` and a `<script>` block. The two blocks compile to a single module and share a top-level scope, so a binding (import, function, or variable) declared in one block and used only in the other is no longer reported as unused. - [#10767](biomejs/biome#10767) [`36d5aa7`](biomejs/biome@36d5aa7) Thanks [@otkrickey](https://github.com/otkrickey)! - Fixed [#10754](biomejs/biome#10754): [`useVueValidVBind`](https://biomejs.dev/linter/rules/use-vue-valid-v-bind/) no longer reports the Vue 3.4+ same-name shorthand as missing a value. `:foo` and `v-bind:foo` are now accepted as equivalent to `:foo="foo"`, while `v-bind`, `v-bind:[dynamicArg]`, and `:[dynamicArg]` without a value continue to be reported. - [#10775](biomejs/biome#10775) [`a918af0`](biomejs/biome@a918af0) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed an issue reported in [#10708](biomejs/biome#10708): `biome rage` didn't detect running Biome daemon pipes on Windows. - [#10730](biomejs/biome#10730) [`5a2e65b`](biomejs/biome@5a2e65b) Thanks [@dinocosta](https://github.com/dinocosta)! - Fixed an issue where Biome was resolving [the well-known Zed settings file](https://biomejs.dev/guides/configure-biome/#well-known-files) from the wrong location on macOS and Windows. - [#10807](biomejs/biome#10807) [`d97fffe`](biomejs/biome@d97fffe) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where `.scss` files were incorrectly analyzed when running `biome check`. - [#10672](biomejs/biome#10672) [`53c6efc`](biomejs/biome@53c6efc) Thanks [@ematipico](https://github.com/ematipico)! - Fixed a bug where Biome incorrectly formatted snippets that have parsing errors. - [#10719](biomejs/biome#10719) [`aa649b5`](biomejs/biome@aa649b5) Thanks [@minseong0324](https://github.com/minseong0324)! - Fixed [`useAwaitThenable`](https://biomejs.dev/linter/rules/use-await-thenable/) false positive when awaiting a custom thenable that is not the global `Promise`.

Biome now keeps the selector before the line comment inline instead of breaking it across descendant combinators. ```diff -.powerPathNavigator - .helm - button.pressedButton, // pressed +.powerPathNavigator .helm button.pressedButton, // pressed .powerPathNavigator .helm button:active:not(.disabledButton) { } ``` - [#10757](biomejs/biome#10757) [`6232fcd`](biomejs/biome@6232fcd) Thanks [@PranavAchar01](https://github.com/PranavAchar01)! - Fixed [#8269](biomejs/biome#8269): the CSS parser now accepts Tailwind `@variant` and `@utility` names that start with a digit, such as the `2xl` breakpoint. ```css @utility container { @variant 2xl { max-width: 1400px; } } ``` - [#10777](biomejs/biome#10777) [`575ced6`](biomejs/biome@575ced6) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed an issue reported in [#10708](biomejs/biome#10708): the GitLab reporter now handles `--verbose` diagnostics filtering correctly. - [#10281](biomejs/biome#10281) [`0efe244`](biomejs/biome@0efe244) Thanks [@Zelys-DFKH](https://github.com/Zelys-DFKH)! - Fixed a bug where GritQL patterns rejected positional (unkeyed) arguments. - [#10758](biomejs/biome#10758) [`e36fd8a`](biomejs/biome@e36fd8a) Thanks [@henrybrewer00-dotcom](https://github.com/henrybrewer00-dotcom)! - Fixed [#10697](biomejs/biome#10697): The formatter no longer removes the parentheses around an `await` or `yield` expression used as the target of a TypeScript instantiation expression. For example, `(await makeFactory)<Value>` is no longer reformatted to `await makeFactory<Value>`, which would change the meaning of the code. - [#10586](biomejs/biome#10586) [`3617094`](biomejs/biome@3617094) Thanks [@IxxyDev](https://github.com/IxxyDev)! - Fixed [#9568](biomejs/biome#9568): [`noFloatingPromises`](https://biomejs.dev/linter/rules/no-floating-promises/) no longer reports a false positive when calling an overloaded function and the selected overload does not return a promise. ```ts function bestEffort(cb: () => Promise<number>): Promise<number>; function bestEffort(cb: () => number): number; function bestEffort( cb: () => number | Promise<number>, ): Promise<number> | number { return cb() as Promise<number> | number; } // This resolves to the second overload, which returns `number`, so it is no // longer flagged as a floating promise. bestEffort(() => 42); ``` - [#10766](biomejs/biome#10766) [`7aff4c1`](biomejs/biome@7aff4c1) Thanks [@JamBalaya56562](https://github.com/JamBalaya56562)! - Fixed [#2862](biomejs/biome#2862): [`noInteractiveElementToNoninteractiveRole`](https://biomejs.dev/linter/rules/no-interactive-element-to-noninteractive-role/) no longer reports custom elements (a tag name containing a dash, e.g. `<my-button role="img" />`). Per the [W3C HTML-ARIA specification](https://www.w3.org/TR/html-aria/#el-autonomous-custom-element), a custom element may be given any role or none. - [#10680](biomejs/biome#10680) [`771daa4`](biomejs/biome@771daa4) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed [#10635](biomejs/biome#10635): Biome now recognizes chained table tests such as `test.concurrent.each()` and `it.concurrent.each()` as test calls, fixing `noMisplacedAssertion` false positives and improving formatting for those test declarations. - [#10759](biomejs/biome#10759) [`34570b5`](biomejs/biome@34570b5) Thanks [@henrybrewer00-dotcom](https://github.com/henrybrewer00-dotcom)! - Fixed [#10636](biomejs/biome#10636): [noStaticElementInteractions](https://biomejs.dev/linter/rules/no-static-element-interactions/) no longer reports a false positive for event handlers on Svelte special elements such as `<svelte:window>`, `<svelte:document>`, and `<svelte:body>`. These are not real DOM elements, so they are now ignored by the rule. - [#10741](biomejs/biome#10741) [`bd2364e`](biomejs/biome@bd2364e) Thanks [@JamBalaya56562](https://github.com/JamBalaya56562)! - Fixed [#6686](biomejs/biome#6686): the `rage` command now respects the `--config-path` option and the `BIOME_CONFIG_PATH` environment variable when loading the Biome configuration. Previously it always used the default configuration resolution and reported the configuration as `Not set` when no `biome.json` existed in the working directory. - [#10763](biomejs/biome#10763) [`2c3e82d`](biomejs/biome@2c3e82d) Thanks [@Aqu1bp](https://github.com/Aqu1bp)! - Fixed [#10742](biomejs/biome#10742): [`noSolidDestructuredProps`](https://biomejs.dev/linter/rules/no-solid-destructured-props) now reports destructured props in Solid function components and JSX children. - [#10606](biomejs/biome#10606) [`a4cc4ab`](biomejs/biome@a4cc4ab) Thanks [@Mokto](https://github.com/Mokto)! - Fixed false positives in `noUnusedImports`, `noUnusedVariables`, and `useImportType` for Svelte components that use both a `<script module>` and a `<script>` block. The two blocks compile to a single module and share a top-level scope, so a binding (import, function, or variable) declared in one block and used only in the other is no longer reported as unused. - [#10767](biomejs/biome#10767) [`36d5aa7`](biomejs/biome@36d5aa7) Thanks [@otkrickey](https://github.com/otkrickey)! - Fixed [#10754](biomejs/biome#10754): [`useVueValidVBind`](https://biomejs.dev/linter/rules/use-vue-valid-v-bind/) no longer reports the Vue 3.4+ same-name shorthand as missing a value. `:foo` and `v-bind:foo` are now accepted as equivalent to `:foo="foo"`, while `v-bind`, `v-bind:[dynamicArg]`, and `:[dynamicArg]` without a value continue to be reported. - [#10775](biomejs/biome#10775) [`a918af0`](biomejs/biome@a918af0) Thanks [@WaterWhisperer](https://github.com/WaterWhisperer)! - Fixed an issue reported in [#10708](biomejs/biome#10708): `biome rage` didn't detect running Biome daemon pipes on Windows. - [#10730](biomejs/biome#10730) [`5a2e65b`](biomejs/biome@5a2e65b) Thanks [@dinocosta](https://github.com/dinocosta)! - Fixed an issue where Biome was resolving [the well-known Zed settings file](https://biomejs.dev/guides/configure-biome/#well-known-files) from the wrong location on macOS and Windows. - [#10807](biomejs/biome#10807) [`d97fffe`](biomejs/biome@d97fffe) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where `.scss` files were incorrectly analyzed when running `biome check`. - [#10672](biomejs/biome#10672) [`53c6efc`](biomejs/biome@53c6efc) Thanks [@ematipico](https://github.com/ematipico)! - Fixed a bug where Biome incorrectly formatted snippets that have parsing errors. - [#10719](biomejs/biome#10719) [`aa649b5`](biomejs/biome@aa649b5) Thanks [@minseong0324](https://github.com/minseong0324)! - Fixed [`useAwaitThenable`](https://biomejs.dev/linter/rules/use-await-thenable/) false positive when awaiting a custom thenable that is not the global `Promise`. A value with a callable `then` member is now recognized as awaitable. ```ts interface Thenable<T> { then(onfulfilled: (value: T) => void): void; } declare const t: Thenable<number>; async function f() { await t; } ``` - [#10734](biomejs/biome#10734) [`4396496`](biomejs/biome@4396496) Thanks [@BangDori](https://github.com/BangDori)! - Fixed [#10708](biomejs/biome#10708): `biome migrate` now preserves trivia when migrating the deprecated `recommended` option to `preset`. - [#10683](biomejs/biome#10683) [`ae31a00`](biomejs/biome@ae31a00) Thanks [@Netail](https://github.com/Netail)! - Fixed [#10657](biomejs/biome#10657) [#10671](biomejs/biome#10671) [#10661](biomejs/biome#10661) [#10637](biomejs/biome#10637) [#10718](biomejs/biome#10718): HTML rules now correctly handle dynamic attributes. - [#10746](biomejs/biome#10746) [`54e8239`](biomejs/biome@54e8239) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where [`noUndeclaredClasses`](https://biomejs.dev/linter/rules/no-undeclared-classes) didn't correctly detect styles defined inside the Astro directive `is:global`. - [#10770](biomejs/biome#10770) [`dd1429c`](biomejs/biome@dd1429c) Thanks [@ematipico](https://github.com/ematipico)! - Improved the Biome Language Server DX by orchestrating certain operations, so that they won't block the editor during typing. This improvement is more visible in large documents. - [#10473](biomejs/biome#10473) [`d9b5133`](biomejs/biome@d9b5133) Thanks [@Mokto](https://github.com/Mokto)! - Improved [`noUnusedImports`](https://biomejs.dev/linter/rules/no-unused-imports/), [`noUnusedVariables`](https://biomejs.dev/linter/rules/no-unused-variables/), [`noUnusedFunctionParameters`](https://biomejs.dev/linter/rules/no-unused-function-parameters/), and [`useImportType`](https://biomejs.dev/linter/rules/use-import-type/) for Svelte, Vue, and Astro files (with `html.experimentalFullSupportEnabled`). Bindings used only in the template — including component tags, attribute interpolations, directives, `bind:` shorthand, and snippet parameters — are no longer reported as unused, while genuinely unused ones still are. - [#10796](biomejs/biome#10796) [`f1b3ab2`](biomejs/biome@f1b3ab2) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where the Biome Language Server didn't enable project or type-aware lint rules, even when they were explicitly enabled. - [#10746](biomejs/biome#10746) [`54e8239`](biomejs/biome@54e8239) Thanks [@ematipico](https://github.com/ematipico)! - Fixed an issue where [`noUndeclaredClasses`](https://biomejs.dev/linter/rules/no-undeclared-classes) didn't detect styles declared inside HTML documents. - [#10774](biomejs/biome#10774) [`bde945b`](biomejs/biome@bde945b) Thanks [@pattrickrice](https://github.com/pattrickrice)! - Fixed [#10268](biomejs/biome#10268) where a race condition resulted in internal errors such as: `The file biome.json does not exist in the workspace`. </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
