# 格式化器

ESLint 带有几个内置的格式化程序来控制 linting 结果的外观，并且还支持第三方格式化程序。

您可以在命令行上使用 --format 或 -f 标志指定格式化程序。例如，--format json 使用 json 格式化程序。

内置格式化程序选项是：

checkstyle
compact
html
jslint-xml
json-with-metadata
json
junit
stylish
tap
unix
visualstudio

# 示例源

每个格式化程序的示例都是使用下面显示的 .eslintrc 配置从 linting fullOfProblems.js 创建的。

# fullOfProblems.js

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

# .eslintrc:

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