Math/Latex Support

[drdrjacobs]

Would it be possible to add support for including latex formulas in emails?

There is currently no great option for including latex in emails, so this would be hugely helpful for those that work in math/science fields.

It seems like this maybe was a planned feature at some point:

but it hasn't been mentioned since.

This was actually an early feature, back in v0.2. Think I removed it because seldom use, and not renderable on receiver unless also using astroid. Or convert math to PNG. You can actually solve it by tweaking the theme and adding mathjax. Might have to allow js.

I see. So the dream would be to get math working in a way that most receivers can see it, and then include some kind of fallback if not as discussed here:

It's crazy that getting that working is so messy.

I guess an alternative that is probably pretty accessible would be to automatically attach a rendered pdf to the email if it contains math. Is this something that could be done as a plugin?

Yes, using cid images is probably the best. But then we need a reliable plain-text fallback.

I might be in a bubble, but in my setting, the TeX code itself is a good fallback, as that is what my contacts write anyway.

Yeah, fair enough. No point in overcomplicating it.

You could just use the markdown feature and pandoc. From my config:

 "markdown_on": true,
 "markdown_processor": "/path/to/pandoc --mathml --self-contained -M pagetitle=Email --template=/path/to/template/template.html --resource-path=.:/home/johannes/Maildir/styles:",

My template.html, derived from the one supplied with pandoc: (click to expand)

~~~html $if(highlighting-css)$ $endif$ $for(css)$ $endfor$ $if(math)$ $math$ $endif$ $for(header-includes)$ $header-includes$ $endfor$ $for(include-before)$ $include-before$ $endfor$ $if(title)$

$title$

$if(subtitle)$

$subtitle$

$endif$ $for(author)$

$author$

$endfor$ $if(date)$

$date$

$endif$

$endif$ $if(toc)$

$table-of-contents$

$endif$ $body$ $for(include-after)$ $include-after$ $endfor$ ~~~

Then, you can easily compose html mails, even styled ones by adding a YAML metadata block like

---
title: Hello World
css: fancy-style.css
---

to the top of your email, where fancy-style.css is in the directory /home/johannes/Maildir/styles.

If you want images instead of mathml for broader support, you can use GladTeX as described in the pandoc manual: First run pandoc to produce htex file, then run gladtex to produce html file, finally run pandoc with option --embed-resources to produce html with inlined images.
