Markdeep：支持图表、公式与 Markdown 语法的纯文本文档
Markdeep – plain text documents with diagrams, equations, and Markdown syntax
2015 — 2022，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
Markdeep 是一个把 Markdown、图表和数学公式统一在纯文本里的文档工具，通过浏览器 JavaScript 渲染；禁用 JavaScript 时降级为可读的纯文本。它多次登上 Hacker News，引发关于简单工具是否该被扩展到画 ASCII 图表的讨论。
为什么经久不衰：它用纯文本统一文档、图表和公式，且无 JS 仍可读，适合快速、可移植的文档，也持续引发关于工具边界的讨论。

质疑用 ASCII 图表替代现成图形工具的实际价值。
如果需要图表，我已经过了 Markdown 阶段。我想不出有什么工作流会因为花 20 分钟用 ASCII 画图而变好，不如用 PowerPoint 20 秒放三张图。我爱 Markdown，用它管理笔记和知识库，但简单优雅的工具被过度延伸用途后就不再有用。

If I need graphic charts/diagrams, I've already passed the markdown stage. There's absolutely no workflow I can think of that is improved by my sitting there and trying to ASCII Art my way into a diagram. Does anyone go, hey, you know what would make my note-taking or web design faster and easier? Spending 20 minutes making an ascii art diagram instead of slapping the same three figures out in powerpoint in 20 seconds. I love markdown. It's an elegant tool for many situations. My own workflow depends on using Kiwi and Noteplan on my phone with a common dropbox directory for their files, which is a project directory for Sublime on my notebook and desktop. All of my organization is a centralized set of markdown'd text documents, be it my calendar or my knowledge base, sync'd across all of my devices and super-easily edited, searched, or converted to web pages. But there is a point where using a simple and elegant tool stops being simple and elegant - it can only be tortured so far outside its intended use-case before it stops being useful.
质疑 Markdown 变体的必要性，认为已有更好的图表扩展方案。
我不明白为什么需要这些 Markdown“风味”。大多数渲染器允许选择不同扩展，而且 Mermaid 等早就能在 Markdown 里画图，比这种费时的 ASCII 艺术格式好得多。

I don't get why we need these Markdown "flavors". Most Markdown renderers allow you to pick and choose different extensions, and graphs have been possible in Markdown for a long time with things like Mermaid, which I think does graphs a lot better than this time consuming ASCII-art format.
认可无 JS 降级为可读纯文本，甚至更喜欢这种形式。
有趣的是，禁用 JavaScript 后两个窗口显示同样的纯文本，我差点评论说用一对 <pre> 标签就能做到。不过我能接受这种降级，文本文件完全可读且信息传达得很好，我甚至有点更喜欢。做得好，楼主。

Funny enough, browsing without Javascript resulted in the same plain text appearing in both windows. I was nearly ready to comment about how easy that is with a pair of <pre> tags. :) That said, I'm OK with it degrading like that. The text file is perfectly readable, and conveys the information within quite well. I even kind of preferred it. So, yeah. Great job, OP.
将 Markdeep 类比为 WordPerfect 的格式控制显示模式，但认为 Markdown 语义更丰富。
有人记得 DOS 版 WordPerfect 5/5.5 吗？有个模式会把插入分页、加粗、斜体等格式操作显示为控制序列。我曾是操作这模式的高手，同学都找我帮忙排版作业。这个 WP5.5 格式让我想起 Markdeep 扩展，好在 Markdown 语义丰富得多。

Anybody remeber the dos version of Wordperfect 5 or 5.5? It had a mode, AFAIK triggered by pressing F11 or was it F12 where every formatting operation like inserting a new page, bold or italics was displayed as a control sequence. Wordperfect didn't care if you five times marked a text as bold and required you to "unbold" five times to continue writing in regular font. I used to be a wizzard operating in this mode and many of my school-mates reached out for me to get their homework assignment properly formatted. Somehow this WP5.5 format reminds me of that Markdown extension. Thankfully markdown is much richer in semantics.
