Possibly fixes#25259, and partial revert of #25133.
---
- `.gitignore` applies only to discovery (walking directory targets, cwd, globs)
- An explicitly named file target is linted / formatted even when gitignored
- = Restoring the pre-[#25133]() behavior for files, while fully keeping the [#25107]() fix for walk roots
| Target | Current | This PR |
| --- | --- | --- |
| Explicit file (`oxlint dist/a.js`) | skipped | linted |
| Explicit directory (`oxlint dist`) | skipped | skipped |
| cwd inside ignored tree | skipped | skipped |
The underlying principle:
> `.gitignore` is a message addressed to git, not to tools.
> Borrowing it to scope discovery is a useful heuristic, and a heuristic may narrow what the walk finds, but never refuse what the user names.
> Only tool's own ignore config can refuse. (which remain hard for the husky staged-file case).
This also re-aligns the CLI with stdin and LSP, which deliberately do not consult `.gitignore` (#19206).
👉🏻 This is the main motivation.
### Why not full revert
A directory target names where to search, not what to process.
The files under it are still discovered by the walk, so discovery rules apply.
Reverting that would bring back [#25107](), whose old behavior was not even a statable spec: whether running inside an ignored tree processed anything depended on the ignore pattern's form (bare `generated` did, `generated/**` didn't), an artifact of walker pruning, not a design.
### Regarding to `--no-ignore`
This flag remains orthogonal as a walk-level opt-out (`--no-ignore=vcs dist`) and for filling gap between existing tools.
However, with explicit files working again, I'm inclined to close those PRs and revisit if demand shows up.
For [#25259]()'s use case: name the files, e.g. `oxlint dist/foo.js` (or shell-expanded glob).
Remove the Prettier related stuff from the conformance, which is purely aimed at JS/TS.
Instead, `oxc_formatter_tests` manage Prettier's test fixtures along with Oxfmt.
Prettier uses the `conditionalGroup` IR for JS and YAML.
When this appeared in JS(containing `conditionalGroup`)-in-HTML(`script` tags)-in-JS (`oxc_formatter`), we previously bypassed the `Doc` to IR conversion.
This PR adds support for this conversion and removes the string format fallback path.
Pure renaming.
- `DispatchOutcome` -> `DispatchResponse` (counter part of `DispatchRequest`)
- `DispatchResult` -> `DispatchPayload` (lives in `DispatchResponse`)
As JSDoc is always contained within the ` * ` fenced comments, the `printWidth` option should not have been used as is.
The dedicated `jsdocPrintWidth` option has not yet been implemented. #24633
Consolidated the criteria for determining which languages are handled by?
- natively by Rust
- passed to Prettier
when formatting embedded code, as these were previously scattered across various places.
Due to historical reasons, the IR was passed as `[Doc, (Doc, ...Doc)]` only when processing `gql-in-js`, whilst for other cases such as `css-in-js` and `html-in-js`, it was always `[Doc]`.
Now, every result is single `Doc`.
- dispatcher
- string_embedder
- tailwind_sorter
Group these 3 together as `SessionServices`, make them available to `FormatSession`, and pass them around.
Previously, as Prettier was required for embedded formatting, so embedding was only supported in `napi` builds.
However, as the number of rewritten Rust components has increased recently, we have enabled embedded formatting in `pure` builds as well, thereby reducing the scope of the `napi` gate.
In the embedding format, issuing a `DispatchRequest` returns a `DispatchOutcome`.
Additionally, by managing the nesting depth, made it possible to limit the number of recursion.
Added a new `ToolBuildResult` struct, so an optional `ClientMessage` can
be passed to `Backend` (in a later PR).
This allows us later to send the custom message to the clients interface
when some config errors happened on the (re)creation.
There is no message sent yet, this will be integrated in another PR too.
This PR is just the base for the `ToolInterface`.
Partially fixes#25196
- Before: create `child_process` worker pool on startup
- Spawned even when nothing needs JS side delegation (e.g. JS/TS-only projects)
- For LSP, the idle workers stayed resident for the whole session
- After: create the pool on the first format that actually delegates to JS side
- Runs that never reach JS side spawn zero workers
- As more formatters are rewritten in Rust, the share of such runs keeps growing
Trade-off: the first JS-delegated format in an LSP session now pays the spawn cost.
But that is what every one-shot CLI run already pays, so it is far from slow, and subsequent formats are unchanged.
Fixes#25107.
The `ignore` crate walker enforces gitignore's "everything under an ignored directory is ignored" rule only by pruning ignored directories during traversal.
And it never filters its walk roots.
So when a walk target (based on cwd or an explicit CLI target path) is already inside a gitignored tree, pruning never happens and a bare directory pattern like `generated` matches nothing file-level. (even though `git check-ignore` says they are ignored)
See also BurntSushi/ripgrep#2595
### Changes
- oxc_config: added `GitignoreChecker`
- a pre-walk check that replays git's resolution order over the ancestor chain
- Matchers and `.git`/`.jj` probes are cached per directory
- oxlint / oxfmt: filter all CLI targets through this check before walking
### Behavior changes
- Explicitly passed gitignored files are now skipped (previously always linted/formatted)
- `oxlint --no-ignore` no longer force-lints gitignored targets
- The same behavior as `--no-ignore` does not disable during walk `.gitignore`
<details>
<summary>FYI: Current our ignore model overview</summary>
Two independent families, AND-ed (a path excluded by any layer is skipped):
| Layer | Source | oxlint | oxfmt |
| -------------------------------------------- | ------------------------------------------------------ | ---------------------------------------------------------------------------------------------- | ---------------------------------------------------- |
| git-derived (always on, not user-disablable) | nested `.gitignore`, `.git/info/exclude` (during walk) | walker via shared `configure_walk_builder` | same (shared) |
| | walk roots / explicit CLI targets | `GitignoreChecker` (this PR) | `GitignoreChecker` (this PR) |
| tool-owned | ignore file | `.eslintignore` / `--ignore-path`; disabled by `--no-ignore` | `.prettierignore` / `--ignore-path`; no disable flag |
| | CLI patterns | `--ignore-pattern`; disabled by `--no-ignore` | `!pattern` path args |
| | config `ignorePatterns` | `LintIgnoreMatcher` (already containment-correct via `matched_path_or_any_parents`); always on | scope-local `is_path_ignored` (same); always on |
NOTE: `ignorePatterns` never had this bug, only the walker-backed gitignore layer did; this PR brings it to the same level.
A `!` negation in `ignorePatterns` cannot re-include gitignored paths (unchanged; the layers are independent).

Follow-up to #25063.
tsx-in-vue was supported in #25063 with a parse-retry (ts fails → retry as tsx), chosen to keep the common ts path single-parse.
However, this leaves a hole: a `lang="tsx"` block without JSX parses fine as plain ts, so the retry never fires and the lone generic comma is removed:
```vue
<script setup lang="tsx">
const identity = <T,>(x: T) => x; // → <T>(x: T) => x, breaks as TS17008
</script>
```
Since parse failure fundamentally cannot detect this, the only fix is to scan the `lang` declaration itself.
The JS host now scans the SFC once per file and passes `_oxfmtVueScriptLang: "tsx"` down to `textToDoc()`. This makes the retry obsolete, so it is removed.
This PR also settles the comma policy: keep it only where it is load-bearing.
- JSX grammar (`<T>` would be a JSX opener)
- and `.mts/.cts` (TS7060, #18928)
and remove it everywhere else, keyed on the grammar, regardless of context.
Deliberate divergence: Prettier keys on filepath and keeps the comma in ts-in-vue/svelte (while its own ts-in-md embed uses `dummy.ts` as `filepath` and removes it). Plain-TS sources now behave identically wherever they live.
Part of #16608, closes#25046.
---
Even with a simple regexp, I don't want to impact the performance of the vast majority of ts-in-vue paths.
With this approach, only tsx-in-vue use cases will be affected, and even that will be kept to a minimum since it can be handled entirely on the Rust side. (JS <-> Rust roundtrip is also slow)
