Brent Westbrook e7a6c19e3a Add `per-file-target-version` option (#16257 ) ## Summary This PR is another step in preparing to detect syntax errors in the parser. It introduces the new `per-file-target-version` top-level configuration option, which holds a mapping of compiled glob patterns to Python versions. I intend to use the `LinterSettings::resolve_target_version` method here to pass to the parser: `f50849aeef/crates/ruff_linter/src/linter.rs (L491-L493)` ## Test Plan I added two new CLI tests to show that the `per-file-target-version` is respected in both the formatter and the linter.		2025-02-24 08:47:13 -05:00

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);
