TypeScript

修复类与接口之间的不一致打印 (#18094, #18091, #18215 by @fisker)

本次版本着重提升了类(Class)与接口(Interface)的格式化一致性。此前这两种相似结构的打印方式存在显著差异，导致视觉效果不统一。现在我们已经对齐了它们的格式化规则，提供更可预测且更清晰的输出效果。

移除了类中类型参数的额外缩进

// Input
interface MarkDef<
  M extends string | Mark = Mark,
  ES extends ExprRef | SignalRef = ExprRef | SignalRef,
>
  extends A, B {}

declare class MarkDef<
  M extends string | Mark = Mark,
  ES extends ExprRef | SignalRef = ExprRef | SignalRef,
>
  implements A, B {}

// Prettier 3.6
interface MarkDef<
  M extends string | Mark = Mark,
  ES extends ExprRef | SignalRef = ExprRef | SignalRef,
> extends A,
    B {}

declare class MarkDef<
    M extends string | Mark = Mark,
    ES extends ExprRef | SignalRef = ExprRef | SignalRef,
  >
  implements A, B {}

// Prettier 3.7
interface MarkDef<
  M extends string | Mark = Mark,
  ES extends ExprRef | SignalRef = ExprRef | SignalRef,
>
  extends A, B {}

declare class MarkDef<
  M extends string | Mark = Mark,
  ES extends ExprRef | SignalRef = ExprRef | SignalRef,
>
  implements A, B {}

将接口继承的打印方式与类对齐

// Input
export interface AreaConfig<ES extends ExprRef | SignalRef>
  extends MarkConfig<ES>, PointOverlayMixins<ES>, LineOverlayMixins<ES> {}

export class AreaConfig<ES extends ExprRef | SignalRef>
  implements MarkConfig<ES>, PointOverlayMixins<ES>, LineOverlayMixins<ES> {}

// Prettier 3.6
export interface AreaConfig<ES extends ExprRef | SignalRef>
  extends MarkConfig<ES>,
    PointOverlayMixins<ES>,
    LineOverlayMixins<ES> {}

export class AreaConfig<ES extends ExprRef | SignalRef>
  implements MarkConfig<ES>, PointOverlayMixins<ES>, LineOverlayMixins<ES> {}

// Prettier 3.7
export interface AreaConfig<ES extends ExprRef | SignalRef>
  extends MarkConfig<ES>, PointOverlayMixins<ES>, LineOverlayMixins<ES> {}

export class AreaConfig<ES extends ExprRef | SignalRef>
  implements MarkConfig<ES>, PointOverlayMixins<ES>, LineOverlayMixins<ES> {}

将单一继承的打印方式与父类对齐

// Input
class ExtendsLongOneWithGenerics
  extends
    Bar<
      SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
      ToBreakLineToBreakLineToBreakLine,
    > {}
class ExtendsLongOneWithGenerics
  implements
    Bar<
      SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
      ToBreakLineToBreakLineToBreakLine,
    > {}
interface ExtendsLongOneWithGenerics
  extends
    Bar<
      SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
      ToBreakLineToBreakLineToBreakLine,
    > {}

// Prettier 3.6
class ExtendsLongOneWithGenerics extends Bar<
  SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
  ToBreakLineToBreakLineToBreakLine
> {}
class ExtendsLongOneWithGenerics
  implements
    Bar<
      SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
      ToBreakLineToBreakLineToBreakLine
    > {}
interface ExtendsLongOneWithGenerics
  extends Bar<
    SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
    ToBreakLineToBreakLineToBreakLine
  > {}

// Prettier 3.7
class ExtendsLongOneWithGenerics extends Bar<
  SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
  ToBreakLineToBreakLineToBreakLine
> {}
class ExtendsLongOneWithGenerics implements Bar<
  SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
  ToBreakLineToBreakLineToBreakLine
> {}
interface ExtendsLongOneWithGenerics extends Bar<
  SomeLongTypeSomeLongTypeSomeLongTypeSomeLongType,
  ToBreakLineToBreakLineToBreakLine
> {}

类与接口体的左花括号打印逻辑不一致

在 Prettier v2.3 中，为增强类头部与主体之间的视觉区分，当类具有多重继承时，我们开始将类主体的起始花括号 { 换行打印。

// Prettier 2.2
class loooooooooooooooooooong
  extends looooooooooooooooooong
  implements loooooooooooooooooooong {
  property: string;
}

// Prettier 2.3
class loooooooooooooooooooong
  extends looooooooooooooooooong
  implements loooooooooooooooooooong
{
  property: string;
}

然而，并非所有人都满意这项改动。

欢迎在此 issue 中留言告知您对此变更应用于接口的看法。

若您有更优的解决方案，我们也非常乐意探讨。

除非出现更优方案，我们将在 Prettier v4 中将接口主体的打印方式与类主体对齐。

// Input
declare class loooooooooooooooooooong
  implements looooooooooooooooooong, loooooooooooooooooooong {
  property: string;
}

interface loooooooooooooooooooong
  extends looooooooooooooooooong, loooooooooooooooooooong {
  property: string;
}

// Prettier 3.7
declare class loooooooooooooooooooong
  implements looooooooooooooooooong, loooooooooooooooooooong
{
  property: string;
}

interface loooooooooooooooooooong
  extends looooooooooooooooooong, loooooooooooooooooooong { // <-- This
  property: string;
}

这些变更同样会影响 Flow 语法

其他变更

JavaScript

允许将导入属性(import attributes)换行显示 (#17329 by @fisker)

// Input
import syntaxImportAssertions from "@babel/plugin-syntax-import-assertions" with {
  BABEL_8_BREAKING: "false",
  USE_ESM: "true", IS_STANDALONE: "false" };

// Prettier 3.6
import syntaxImportAssertions from "@babel/plugin-syntax-import-assertions" with { BABEL_8_BREAKING: "false", USE_ESM: "true", IS_STANDALONE: "false" };

// Prettier 3.7
import syntaxImportAssertions from "@babel/plugin-syntax-import-assertions" with {
  BABEL_8_BREAKING: "false",
  USE_ESM: "true",
  IS_STANDALONE: "false",
};

新增对"Discard Bindings"提案的支持 (#17708 by @fisker)

Stage 2 阶段的 "Discard Bindings" 提案现已通过 Babel 获得支持。请注意在使用此提案语法特性前，请先了解我们关于非标准语法的政策声明。

const [void] = x;

const {x:void} = x;

修复注释格式不一致问题 (#17723 by @fisker)

// Input
if (
  true
  // This is a really complicated part of the condition, so we need a big ol'
  // comment here to explain it.
  && flibble.blibble.blobble?.bloo
) {
  doThings();
}

// Prettier 3.6 (--parser=typescript --experimental-operator-position=start)
if (
  true
  && // This is a really complicated part of the condition, so we need a big ol'
  // comment here to explain it.
  flibble.blibble.blobble?.bloo
) {
  doThings();
}

// Prettier 3.6 (--parser=babel --experimental-operator-position=start)
if (
  true
  // This is a really complicated part of the condition, so we need a big ol'
  // comment here to explain it.
  && flibble.blibble.blobble?.bloo
) {
  doThings();
}

// Prettier 3.7
if (
  true
  // This is a really complicated part of the condition, so we need a big ol'
  // comment here to explain it.
  && flibble.blibble.blobble?.bloo
) {
  doThings();
}

新增 Playwright 测试函数支持 (#17876 by @BPScott)

当为测试函数添加 .skip 时，Prettier 已能避免改变其缩进格式。现在对于 Playwright 的 test.fixme、test.describe.skip 和 test.describe.fixme 函数，Prettier 也将其视为与 test.skip 类似进行处理。

// Input
test.fixme("does something really long and complicated so I have to write a very long name for the test", () => {
  // code
});

test.describe.skip("does something really long and complicated so I have to write a very long name for the test", () => {
  // code
});

test.describe.fixme("does something really long and complicated so I have to write a very long name for the test", () => {
  // code
});

// Prettier 3.6
test.fixme(
  "does something really long and complicated so I have to write a very long name for the test",
  () => {
    // code
  },
);

test.describe.skip(
  "does something really long and complicated so I have to write a very long name for the test",
  () => {
    // code
  },
);

test.describe.fixme(
  "does something really long and complicated so I have to write a very long name for the test",
  () => {
    // code
  },
);

// Prettier 3.7
test.fixme("does something really long and complicated so I have to write a very long name for the test", () => {
  // code
});

test.describe
  .skip("does something really long and complicated so I have to write a very long name for the test", () => {
  // code
});

test.describe
  .fixme("does something really long and complicated so I have to write a very long name for the test", () => {
  // code
});

避免因长模块名导致 `{import,require.resolve,require.resolve.paths,import.meta.resolve}()` 换行 (#17882, #17908 by @kovsu & @fisker)

// Input
const a = require("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");
const b = require.resolve("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");
const c = require.resolve.paths("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");

const d = await import("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module")
const e = import.meta.resolve("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");

// Prettier 3.6
const a = require("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");
const b = require.resolve(
  "./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module",
);
const c = require.resolve.paths(
  "./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module",
);

const d = await import(
  "./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module"
);
const e = import.meta.resolve(
  "./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module",
);

// Prettier 3.7
const a = require("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");
const b =
  require.resolve("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");
const c = require.resolve
  .paths("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");

const d =
  await import("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");
const e = import.meta
  .resolve("./a/long/long/long/long/long/long/long/long/long/long/long/path/to/module");

优化 if 语句内的注释处理 (#17998 by @fisker)

// Input
if (foo) // comment
{
  doThing();
} else // comment for else
{
  doSomethingElse();
}

// Prettier 3.6
if (foo) {
  // comment
  doThing();
} // comment for else
else {
  doSomethingElse();
}

// Prettier 3.7

{
  doThing();
} else // comment for else
{
  doSomethingElse();
}

改进带注释的 `require()` 调用处理 (#18037 by @fisker)

require(
// Comment
"foo"
);

// Prettier 3.6
require(// Comment
"foo");

// Prettier 3.7
require(
  // Comment
  "foo",
);

移除 `Boolean()` 调用中逻辑表达式的缩进 (#18087 by @kovsu)

当将条件取反值或切换 !! 和 Boolean() 用法时，减少代码差异。

// Input
const foo = Boolean(
  a_long_long_condition ||
  a_long_long_long_condition ||
  a_long_long_long_condition
);
const bar = !!(
  a_long_long_condition ||
  a_long_long_long_condition ||
  a_long_long_long_condition
);

// Prettier 3.6
const foo = Boolean(
  a_long_long_condition ||
    a_long_long_long_condition ||
    a_long_long_long_condition,
);
const bar = !!(
  a_long_long_condition ||
  a_long_long_long_condition ||
  a_long_long_long_condition
);

// Prettier 3.7
const foo = Boolean(
  a_long_long_condition ||
  a_long_long_long_condition ||
  a_long_long_long_condition
);
const bar = !!(
  a_long_long_condition ||
  a_long_long_long_condition ||
  a_long_long_long_condition
);

// Input
for (
  index = 0;
  doSomething(foo[index]) !== bar && doSomething(foo[index]) !== baz;
  index ++
) /* No op */;

// Prettier 3.6
for (
  index = 0;
  doSomething(foo[index]) !== bar && doSomething(foo[index]) !== baz;
  index++ /* No op */
);

// Prettier 3.7
for (
  index = 0;
  doSomething(foo[index]) !== bar && doSomething(foo[index]) !== baz;
  index++
) /* No op */ ;

修复类方法与对象方法间注释打印不一致问题 (#18147 by @fisker)

// Input
class x {
  method() // Class method
  {
    return 1
  }
}

const object = {
  method() // Object method
  {
    return 1
  }
}

// Prettier 3.6
class x {
  method() { // Class method
    return 1;
  }
}

const object = {
  method() {
    // Object method
    return 1;
  },
};

// Prettier 3.7

// Prettier 3.6
assert.deepStrictEqual(linesCollection.getViewLinesIndentGuides___(-1, -1), [
  1,
]);
assert.deepStrictEqual(

API

允许 `plugin.parser.preprocess()` 返回 `Promise` (#17679 by @fisker)

与 plugin.printer.preprocess() 保持一致，后者允许返回 Promise。

我们仍建议将异步工作移至 plugin.parser.parse() 中处理（该函数本身已支持返回 Promise），未来可能会移除对 plugin.parser.preprocess() 的支持。

允许 `AstPath#call()` 访问空值属性的成员 (#17860 by @fisker)

此前要检查可能不存在的子节点，必须先确认节点存在：

const isFoo = path.call(() => path.node?.type === "Foo", "foo", "bar");
// Uncaught TypeError: Cannot read properties of undefined (reading 'bar')

必须进行如下操作：

const isFoo =
  path.node.foo?.bar &&
  path.call(() => path.node?.type === "Foo", "foo", "bar");

自 Prettier 3.7 起，访问空值属性的成员不再抛出错误。

向 `plugin.printer.canAttachComment()` 传递祖先节点信息 (#18055 by @fisker)

这能防止将注释附加到节点的特定子节点上。

例如在 JavaScript 代码 const object = {property}; 中，Identifier 节点 (property) 在 AST 中同时作为 Property.key 和 Property.value 出现，显然它只能被打印一次。若注释附加到不可打印的子节点上，注释将会丢失。

插件现在可通过添加如下 canAttachComment 函数避免此问题：

export const canAttachComment = (node, [parent]) =>
  !(
    parent?.type === "Property" &&
    parent.shorthand &&
    parent.key === node &&
    parent.key !== parent.value
  );

export const print = (path, options, print) => {
  const { node } = path;
  switch (node.type) {
    case "Property":
      if (node.shorthand) {
        return print("value");
      }
    // ...
  }
};

新增对 `plugin.printer.printPrettierIgnored()` 的支持 (#18070 by @fisker)

对于带有 prettier-ignore 注释的节点，Prettier 会直接打印该节点的文本。但这可能引发问题，例如当节点需要添加括号，或在 --no-semi 模式下需要打印前置分号来避免自动分号插入(ASI)问题时。

自 Prettier 3.7 起，插件可向 printer 添加 printPrettierIgnored() 函数，用于自定义被 prettier-ignore 节点的打印流程。该函数采用与 plugin.printer.print() 完全相同的签名。

允许插件提供 `estree` 打印器 (#18072 by @fisker)

此前，若插件开发者希望基于内置 printer 创建输出不同代码的 estree printer，则必须同时提供 parsers 和 printers。Prettier 3.7 允许插件开发者创建仅提供 estree printer 的插件。

CLI

避免在未启用 `--cache` 时创建 `node_modules/.cache/` 目录 (#18124 by @chiawendt)

在不使用 --cache 参数的情况下运行 prettier . 时，将不再创建空的 node_modules/.cache/ 目录。
