# How do I live preview markdown, rendering math, checkboxes, etc.?

I’m using Spacemacs with markdown-mode and I’ve configured it according to Jason Blevins’ guide.

## Other things I’ve tried

• Pandoc works pretty well except when I set the —lua-filter=task-list.lua flag and I don’t have chackboxes to render (but it only fails with certain files and I have no idea why). This doesn’t give me a live preview though.

• I love the mume-cli package, which uses the mume library on which markdown-preview-enhanced is based, but I can’t configure it the way I can in VSCode. (I can modify a js file in Linux, but I can’t find that file in any of the directories inside of the node_modules directories). It does generate an html file that I can open in the browser, but whenever I export, Emacs asks if I want to overwrite my html file twice. I have to answer yes, then no in order to get it to render successfully. I also have to manually reload the page in my browser each time.

• livedown, flyit-md, and vue do not do what I’m asking.

I know a simple solution is to use VSCode for Markdown editing, but I don’t like how the Vim extension works (or doesn’t).

## Limitations

• I don’t know how to configure a node.js package without rebuilding it (and it doesn’t look like I can build a package before publishing it...). The npm sites have these configurations people can make, but no comments on where to put the text snippets they offer as examples.

• I don’t know or have much time to learn Lisp or JavaScript/TypeScript. I want to use a package someone else has written and configure markdown-mode to call it.

• I want a live preview that renders math (MathJax and KaTeX) as well as checkboxes. This is a good set of capabilities I’d like.

• I want to do this with Emacs.

• I do not want to configure/build anything each time I have a file with different Mardown features. Just one command for whatever file I have open in the current buffer.

• It sounds like you have a "How do I do X?" question, where X has a list of criteria. Could you please state the question explicitly? Q&A here works best for narrow, concrete, specific questions. Broad, exploratory questions are typically less useful (and some questions are simply closed as too broad). – Drew Oct 27 '18 at 19:22
• I'm not sure if your criteria require that your solution be within emacs. But if you're using windows or macOS marked 2 is probably your best bet. It integrates nicely with markdown-mode using markdown-open-command. You can read about it in the customization section of markdown-mode. – mclear Jan 28 at 0:27
