格式化工具参考

ESLint 有几个用来控制提示结果外观的内置格式化工具,同时也支持第三方格式化工具。

你可以在命令行中使用 --format--f 标志来指定格式化工具。例如,--format json 使用 json 格式化。

内置的格式化选项有:

源码示例

每个格式化示例都是用 .eslintrc.json 配置检查 fullOfProblems.js 得到的。

fullOfProblems.js

function addOne(i) {
    if (i != NaN) {
        return i ++
    } else {
      return
    }
};

.eslintrc.json

{
    "extends": "eslint:recommended",
    "rules": {
        "consistent-return": 2,
        "indent"           : [1, 4],
        "no-else-return"   : 1,
        "semi"             : [1, "always"],
        "space-unary-ops"  : 2
    }
}

使用命令行测试格式化工具:

npx eslint --format <Add formatter here> fullOfProblems.js

内置格式化工具选项

checkstyle

输出结果使用 Checkstyle 格式:

输出示例:

<?xml version="1.0" encoding="utf-8"?><checkstyle version="4.3"><file name="/var/lib/jenkins/workspace/Releases/eslint Release/eslint/fullOfProblems.js"><error line="1" column="10" severity="error" message="&amp;apos;addOne&amp;apos; is defined but never used.

compact

人类可读的输出格式。模仿 JSHint 的默认输出。

输出示例:

html

输出结果为 HTML。html 格式化对于在浏览器中的可视化展示很有用。

输出示例:

jslint-xml

输出结果格式与 JSLint Jenkins 插件兼容。

输出示例:

json-with-metadata

输出 JSON 序列化 结果。json-with-metadata 提供与 json 格式化相同的提示结果,并提供关于应用规则的额外元数据。判断结果包含在 results 属性中,规则元数据包含在 metadata 属性中。

另外,你可以使用 ESLint Node.js API 来编程使用 ESLint。
