Re: MathML in HTML export with the help of groff

Hello Rudy. Thanks for the heads-up. For now I stick with my solution. It's working and the result looks fine to me. I never seen or appreciated the difference between a roff and TeX output anyway. Never the less after the merge I will try it out. Markus

MathML in HTML export with the help of groff

Hello everyone, For a static web-site export without JavaScript, I needed to include some math. Stand alone formulas could be pictures, but this is no solution for inline math expressions. Today all Web-Browser support MathML for this. From [[https://lists.gnu.org/archive/html/emacs-orgmode/2025-

Hey Ihor, Thanks for the review! There’s no rush, I’m still trying to find time to work on the HTTP side. Before sending v2 I wanted to clarify how to handle one of your comments. On 2025-10-12 07:28, Ihor Radchenko wrote: >>- (const :tag "Use dvipng to make images" dvipng) >>- (cons
