忽略代码

使用 .prettierignore 完全忽略（即不重新格式化）某些文件和文件夹。

¥Use .prettierignore to ignore (i.e. not reformat) certain files and folders completely.

使用“prettier-ignore”注释来忽略部分文件。

¥Use “prettier-ignore” comments to ignore parts of files.

忽略文件：.prettierignore

¥Ignoring Files: .prettierignore

要从格式中排除文件，请在项目的根目录中创建一个 .prettierignore 文件。.prettierignore 使用 gitignore 语法。

¥To exclude files from formatting, create a .prettierignore file in the root of your project. .prettierignore uses gitignore syntax.

示例：

¥Example:

# Ignore artifacts:
build
coverage

# Ignore all HTML files:
**/*.html

建议在你的项目中有一个 .prettierignore！通过这种方式，你可以运行 prettier --write . 以确保所有内容都已格式化（不会破坏你不想要的文件，或阻塞生成的文件）。而且 - 你的编辑器会知道哪些文件不应该格式化！

¥It’s recommended to have a .prettierignore in your project! This way you can run prettier --write . to make sure that everything is formatted (without mangling files you don’t want, or choking on generated files). And – your editor will know which files not to format!

默认情况下，prettier 会忽略版本控制系统目录（".git"、".jj"、".sl"、".svn" 和 ".hg"）和 node_modules（除非指定了 --with-node-modules CLI 选项）中的文件。如果 ".gitignore" 文件存在于运行它的同一目录中，Prettier 还将遵循 ".gitignore" 文件中指定的规则。

¥By default prettier ignores files in version control systems directories (".git", ".jj", ".sl", ".svn" and ".hg") and node_modules (unless the --with-node-modules CLI option is specified). Prettier will also follow rules specified in the ".gitignore" file if it exists in the same directory from which it is run.

所以默认情况下它将是

¥So by default it will be

**/.git
**/.svn
**/.hg
**/node_modules

和

¥and

**/.git
**/.svn
**/.hg

如果 --with-node-modules CLI 选项提供

¥if --with-node-modules CLI option provided

（另见 --ignore-path CLI 选项。）

¥(See also the --ignore-path CLI option.)

JavaScript

// prettier-ignore 的 JavaScript 注释将从格式化中排除抽象语法树中的下一个节点。

¥A JavaScript comment of // prettier-ignore will exclude the next node in the abstract syntax tree from formatting.

例如：

¥For example:

matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)

// prettier-ignore
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)

将转换为：

¥will be transformed to:

matrix(1, 0, 0, 0, 1, 0, 0, 0, 1);

// prettier-ignore
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)

JSX

<div>
  {/* prettier-ignore */}
  <span     ugly  format=''   />
</div>

HTML

<!-- prettier-ignore -->
<div         class="x"       >hello world</div            >

<!-- prettier-ignore-attribute -->
<div
  (mousedown)="       onStart    (    )         "
  (mouseup)="         onEnd      (    )         "
></div>

<!-- prettier-ignore-attribute (mouseup) -->
<div
  (mousedown)="onStart()"
  (mouseup)="         onEnd      (    )         "
></div>

CSS

/* prettier-ignore */
.my    ugly rule
{

}

Markdown

<!-- prettier-ignore -->
Do   not    format   this

范围忽略

¥Range Ignore

在 v1.12.0+ 中可用

¥available in v1.12.0+

这种类型的忽略只允许在顶层使用，旨在禁用自动生成内容的格式，例如 all-contributors、markdown-toc 等

¥This type of ignore is only allowed to be used in top-level and aimed to disable formatting for auto-generated content, e.g. all-contributors, markdown-toc, etc.

<!-- prettier-ignore-start -->
<!-- SOMETHING AUTO-GENERATED BY TOOLS - START -->

| MY | AWESOME | AUTO-GENERATED | TABLE |
|-|-|-|-|
| a | b | c | d |

<!-- SOMETHING AUTO-GENERATED BY TOOLS - END -->
<!-- prettier-ignore-end -->

重要：你必须在  和  之前有一个空行，以便 Prettier 识别注释。

¥Important: You must have a blank line before  and  for Prettier to recognize the comments.

YAML

要忽略 YAML 文件的一部分，# prettier-ignore 应该放在被忽略节点上方的行上：

¥To ignore a part of a YAML file, # prettier-ignore should be placed on the line immediately above the ignored node:

# prettier-ignore
key  : value
hello: world

GraphQL

{
  # prettier-ignore
  addReaction(input:{superLongInputFieldName:"MDU6SXNzdWUyMzEzOTE1NTE=",content:HOORAY}) {
    reaction {content}
  }
}

Handlebars

{{! prettier-ignore }}
<div>
  "hello! my parent was ignored"
  {{#my-crazy-component     "shall"     be="preserved"}}
    <This
      is  =  "also preserved as is"
    />
  {{/my-crazy-component}}
</div>

命令行文件模式

¥Command Line File Patterns

对于一次性命令，当你想排除一些文件而不将它们添加到 .prettierignore 时，否定模式可以派上用场：

¥For one-off commands, when you want to exclude some files without adding them to .prettierignore, negative patterns can come in handy:

prettier . "!**/*.{js,jsx,vue}" --write
