# format_regexp_* 格式设置

> ClickHouse 在 format_regexp_* 自动生成分组中的格式设置。

export const SettingsInfoBlock = ({type, default_value, changeable_without_restart}) => {
  return <div className="not-prose" style={{
    display: "flex",
    flexWrap: "wrap",
    alignItems: "baseline",
    columnGap: "0.5rem",
    rowGap: "0.125rem",
    margin: "0.375rem 0",
    fontSize: "0.8125rem",
    lineHeight: "1.125rem"
  }}>
      <div style={{
    fontWeight: 600,
    opacity: 0.72
  }}>类型</div>
      <div style={{
    overflowWrap: "anywhere"
  }}>{type}</div>
      <div style={{
    fontWeight: 600,
    opacity: 0.72,
    marginInlineStart: "0.5rem"
  }}>默认值</div>
      <div style={{
    overflowWrap: "anywhere"
  }}>{default_value}</div>
      {changeable_without_restart && <div style={{
    fontWeight: 600,
    opacity: 0.72,
    marginInlineStart: "0.5rem"
  }}>
          无需重启即可更改
        </div>}
      {changeable_without_restart && <div style={{
    overflowWrap: "anywhere"
  }}>
          {changeable_without_restart}
        </div>}
    </div>;
};

这些设置是根据 [源代码](https://github.com/ClickHouse/ClickHouse/blob/master/src/Core/FormatFactorySettings.h) 自动生成的。

<div id="format_regexp">
  ## format\_regexp
</div>

正则表达式 (Regexp 格式)

<div id="format_regexp_escaping_rule">
  ## format\_regexp\_escaping\_rule
</div>

<SettingsInfoBlock type="EscapingRule" default_value="Raw" />

<VersionHistory rows={[{"id": "row-1","items": [{"label": "20.10"},{"label": "Raw"},{"label": "将 Raw 设为 Regexp 格式的默认转义规则，使其行为更符合用户预期"}]}]} />

用于 Regexp 格式的字段转义规则

<div id="format_regexp_skip_unmatched">
  ## format\_regexp\_skip\_unmatched
</div>

<SettingsInfoBlock type="Bool" default_value="0" />

跳过与正则表达式不匹配的行 (适用于 Regexp 格式)
