Brent Westbrook 96f3c8d1ab Convert `OldDiagnostic::noqa_code` to an `Option<String>` (#18946 ) ## Summary I think this should be the last step before combining `OldDiagnostic` and `ruff_db::Diagnostic`. We can't store a `NoqaCode` on `ruff_db::Diagnostic`, so I converted the `noqa_code` field to an `Option<String>` and then propagated this change to all of the callers. I tried to use `&str` everywhere it was possible, so I think the remaining `to_string` calls are necessary. I spent some time trying to convert _everything_ to `&str` but ran into lifetime issues, especially in the `FixTable`. Maybe we can take another look at that if it causes a performance regression, but hopefully these paths aren't too hot. We also avoid some `to_string` calls, so it might even out a bit too. ## Test Plan Existing tests --------- Co-authored-by: Micha Reiser <micha@reiser.io>		2025-06-27 11:36:55 -04:00

Ruff WASM

⚠️ WARNING: This API is experimental and may change at any time

Docs | Playground

An extremely fast Python linter and code formatter, written in Rust.

This is a WASM version of the Ruff API which can be used to lint/format Python in a browser environment.

There are multiple versions for the different wasm-pack targets. See here for more info on targets.

Usage

This example uses the wasm-pack web target and is known to work with Vite.

import init, { Workspace, type Diagnostic } from '@astral-sh/ruff-api';

const exampleDocument = `print('hello'); print("world")`

await init(); // Initializes WASM module

// These are default settings just to illustrate configuring Ruff
// Settings info: https://docs.astral.sh/ruff/settings
const workspace = new Workspace({
  'line-length': 88,
  'indent-width': 4,
  format: {
    'indent-style': 'space',
    'quote-style': 'double',
  },
  lint: {
    select: [
      'E4',
      'E7',
      'E9',
      'F'
    ],
  },
});

// Will contain 1 diagnostic code for E702: Multiple statements on one line
const diagnostics: Diagnostic[] = workspace.check(exampleDocument);

const formatted = workspace.format(exampleDocument);
