I think HTML tidy is one of the household names in that field.
要获得此问题的更新的、与操作系统无关的答案：
虽然 原始 < href="http://tidy.sourceforge.net/" rel="nofollow noreferrer">HTMLTidy 项目已休眠超过 6 年，“W3C 社区和业务小组”，名称为 “HTML Tidy Advocacy Community Group ( HTACG）”现已开始继续开发，目标是使其完全兼容 HTML5。该组织成立于 2015 年 1 月，尽管他们将当前状态描述为“正在进行中”，但二进制文件已经可供下载。
To have an updated, OS-agnostic answer to this question:
While the original HTMLTidy project has been dormant for over 6 years, a "W3C Community & Business group" that goes by the name "HTML Tidy Advocacy Community Group (HTACG)" has now begun to continue its development, with the goal of making it fully HTML5-compatible. The group was formed in January 2015 and although they describe the current state as "work in progress", binaries are already available for download.

正如您所期望的那样，Homebrew 安装了
tidy-html5。它被链接为
