如何为 WebStorm 配置 eslint 缩进?

[英]How to configure eslint indent for WebStorm?

如何在.eslintr.json设置"indent"以匹配.eslintr.json中使用的默认值?

在此处输入图片说明

到目前为止,我尝试过的一切,根据官方文档都无法匹配:

  • "indent": ["error", 2] - 给出了许多Expected indentation of 2 spaces but found 4
  • "indent": ["error", 4] - 给出了许多Expected indentation of 4 spaces but found 8
  • "indent": ["error", 8] - 给出了许多Expected indentation of 8 spaces but found 4

我完整的 eslint 配置:

{
  "env": {
    "es6": true,
    "node": true,
    "jasmine": true
  },
  "extends": "eslint:recommended",
  "parserOptions": {
  },
  "rules": {
    "no-else-return": "error",
    "no-multi-spaces": "error",
    "no-whitespace-before-property": "error",
    "camelcase": "error",
    "new-cap": "error",
    "no-console": "error",
    "comma-dangle": "error",
    "no-var": "error",
    "indent": ["error", 4],
    "quotes": [
      "error",
      "single"
    ],
    "semi": [
      "error",
      "always"
    ]
  }
}

当我输入代码时,我总是使用Ctrl+Alt+L来自动格式化代码,并且生成的代码格式不符合任何 eslint 设置。


更新

正如所问, "indent": ["error", 4]的代码示例"indent": ["error", 4]

对于此代码:(通过 Ctrl+Alt+L 格式化)

const a = 123;
switch (a) {
    case 1:
        return 1;
    case 2:
        return 2;
    case 3:
        return 3;
    default:
        break;
}

结果是:

3:1  error  Expected indentation of 0 spaces but found 4
4:1  error  Expected indentation of 4 spaces but found 8
5:1  error  Expected indentation of 0 spaces but found 4
6:1  error  Expected indentation of 4 spaces but found 8
7:1  error  Expected indentation of 0 spaces but found 4
8:1  error  Expected indentation of 4 spaces but found 8
9:1  error  Expected indentation of 0 spaces but found 4
10:1  error  Expected indentation of 4 spaces but found 8

例子2

obj.format('text', {
        value: '${two}'
    }
);

结果是:

2:1   error  Expected indentation of 4 spaces but found 8
3:1   error  Expected indentation of 0 spaces but found 4

例3

return begin()
    .then(() => {
            return callback()
                .then(data => {
                    success = true;
                    return commit();
                }, reason => {
                    return rollback();
                })
        },
        function (reason) {
            update(false, false, reason);
            return $p.reject(reason);
        });

结果是:

3:1   error  Expected indentation of 8 spaces but found 12
4:1   error  Expected indentation of 12 spaces but found 16
5:1   error  Expected indentation of 16 spaces but found 20
6:1   error  Expected indentation of 16 spaces but found 20
7:1   error  Expected indentation of 12 spaces but found 16
8:1   error  Expected indentation of 16 spaces but found 20
9:1   error  Expected indentation of 12 spaces but found 16
10:1   error  Expected indentation of 4 spaces but found 8
11:1   error  Expected indentation of 4 spaces but found 8
12:1   error  Expected indentation of 8 spaces but found 12
13:1   error  Expected indentation of 8 spaces but found 12
14:1   error  Expected indentation of 4 spaces but found 8

Switch-Case 似乎是 eslint 关于缩进的一个特例。 默认case下, case子句不相对于switch缩进:

“SwitchCase”(默认值:0)对 switch 语句中的 case 子句强制执行缩进级别

请参见此处的示例: http : //eslint.org/docs/rules/indent#switchcase

您需要像这样将SwitchCase选项设置为 1:

"indent": [
    "error", 
    4, 
    {"SwitchCase": 1}
]

所以你完整的 eslint 配置现在看起来像这样:

{
    "env": {
        "es6": true,
        "node": true,
        "jasmine": true
    },
    "extends": "eslint:recommended",
    "parserOptions": {
    },
    "rules": {
        "no-else-return": "error",
        "no-multi-spaces": "error",
        "no-whitespace-before-property": "error",
        "camelcase": "error",
        "new-cap": "error",
        "no-console": "error",
        "comma-dangle": "error",
        "no-var": "error",
        "indent": ["error", 4, {"SwitchCase": 1}],
        "quotes": [
            "error",
            "single"
        ],
        "semi": [
            "error",
            "always"
        ]
    }
}

关于你的第二个例子,我认为这样写是很常见的:

obj.format('text', {
    value: '${two}'
});

两个括号都在同一行打开,因此您可以在同一行关闭它们。 如果您在该行上使用自动格式,它们将不会改变。

第三个例子看起来有点棘手。 我不知道您是否可以在同一页面上为该页面获取 eslint 和自动格式。 我个人更喜欢 eslint 方式,但我不知道你是否可以调整自动格式来做到这一点。

编辑:你可以这样写:

return begin()
    .then(() => callback()
        .then(data => {
            success = true;
            return commit();
        }, reason => {
            return rollback();
        }),
        function(reason) {
            update(false, false, reason);
            return $p.reject(reason);
        });

我通过将缩进配置添加到文件.eslintrc.js 中来修复它

module.exports = {
    "rules": {
        "indent": ["error", 4]
    }
};

由于WebStorm格式,您似乎收到错误WebStorm


解决方案

在网络webstorm

  • File -> Setting
  • 转到Editor -> Code Style -> HTML
  • Do not indent children of ,添加标记script
  • 然后再次格式化源代码。

那么错误应该消失了。
