We are pleased to announce the release of textlint v14.0.0. This release includes a number of new features and improvements.

Summary​

textlint v14 requires Node.js v18.14.0;.

Node.js 16 is already EOL, so we drop support for Node.js 16. If you use older Node.js, you need to upgrade Node.js to LTS(Long Term Support) version.

Breaking Changes for user​

Drop Node.js 16 support​

textlint v14 requires Node.js v18.14.0+. You need to upgrade Node.js to 18 or 20.

For textlint developer, textlint-scripts also requires Node.js v18.19.0+.

Move gulp-textlint to out of monorepo​

We move gulp-textlint to out of monorepo.

gulp-textlint is not maintained by textlint core team.

If you interested in gulp-textlint, please check the following issue:

Remove --parallel and --maxConcurrency flag​

textlint v14 removes --parallel and --maxConcurrency flag. This flag is for parallel linting, but It is not used by many users.

We may visit again, but we will delete this experimental flag once.

Remove @textlint/linter-formatter CLI​

@textlint/linter-formatter includes CLI, but it is not used by many users. So, we remove the CLI from @textlint/linter-formatter.

Breaking Changes for developer​

Change textlint-scirpts output target​

textlint-scripts output target is changed to Node.js v18.14.0.

Previously, It output ES2015-compatible JavaScript. In textlint v14, It outputs ES2022-compatible JavaScript.

It means that textlint-scripts output JavaScript is compatible with Node.js v18.14.0+. It aims to support the latest JavaScript features and improve the performance of the output.

Add deprecation warning to old APIs​

textlint v14 adds a deprecation warning to old APIs. Old APIs are textlint, TextLintCore, TextLintEngine, and TextFixEngine of textlint package.

There are replaced by createLinter and loadTextlintrc, and loadLinerFormatter since v13.0.0.

Depretead old APIs​

Depreacate four APIs in textlint package.

Old APINew API
textlintuse @textlint/legacy-textlint-core or @textlint/kernel
TextLintCoreuse @textlint/legacy-textlint-core or @textlint/kernel
TextLintEngineuse createLinter and loadTextlintrc
TextFixEngineuse createLinter and loadTextlintrc

How to control the deprecation message?​

  • If the NODE_OPTIONS=--throw-deprecation is used, the deprecation warning is thrown as an exception rather than being emitted as an event.
  • If the NODE_OPTIONS=--no-deprecation is used, the deprecation warning is suppressed.
  • If the NODE_OPTIONS=--trace-deprecation is used, the deprecation warning is printed to stderr along with the full stack trace.

If you want to find the usage of deprecation APIs, you can run with NODE_OPTIONS=--throw-deprecation env.

NODE_OPTIONS=--throw-deprecation node your-script.js

For more details, see process.emitWarning(warning[, options]).

Migration Guide​

TextLintEngine/TextFixEngine migration​

Use createLinter and loadTextlintrc instead of TextLintEngine/TextFixEngine

import { TextLintEngine } from "textlint";
import path from "path";
function lintFile(filePath) {
  const engine = new TextLintEngine({
    formatterName: "stylish",
  });
  const filePathList = [filePath];
  return engine.executeOnFiles(filePathList).then(function (results) {
    const output = engine.formatResults(results);
    console.log(output);
  });
}
lintFile(path.resolve(process.cwd(), "README.md"));

→

import { createLinter, loadTextlintrc, loadLinterFormatter } from "textlint";
import path from "node:path";
import { fileURLToPath } from "node:url";
async function lintFile(filePath) {
    // descriptor is a structure object for linter
    // It includes rules, plugins, and options
    const descriptor = await loadTextlintrc({
        configFilePath: path.join(process.cwd(), ".textlintrc.json")
    });
    const linter = createLinter({
        descriptor
    });
    const results = await linter.lintFiles([filePath]);
    // textlint has two types formatter sets for linter and fixer
    const formatter = await loadLinterFormatter({ formatterName: "stylish" });
    const output = formatter.format(results);
    console.log(output);
}
lintFile(path.join(process.cwd(), "README.md")
TextLintCore and textlint migration​

Use @textlint/legacy-textlint-core instead of it. This package is deprecated, but you can migrate it smooth.

- import { TextLintCore } from "textlint";
+ import { TextLintCore } from "@textlint/legacy-textlint-core";
const textlint = new TextLintCore();
