Prettify math is a emacs minor mode to prettify math formulas.

Note this project current only support mac & linux, NOT windows as a bug in jsonrpc.

It’s base on mathjax, refer mathjax for math formula related stuffs. Default math formula delimiters:

`	inline asciimath
``	block asciimath
$	inline latex
$$	block latex

Prerequisite

nodejs - used to run mathjax, if not available simple installation refer: Installing Node.js

Installation

via straight.el

(straight-use-package '(prettify-math :host nil :repo "https://github.com/shaqtsui/prettify-math" :files (:defaults "mathjax-jsonrpc.js")))

or from melpa

1. add melpa in init.el if not available

   (require 'package)
   (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
   (package-initialize)
       

2. command: M-x package-refresh-contents RET M-x package-install RET prettify-math RET

Usage

Enable in current buffer: M-x prettify-math-mode RET, or globally: M-x global-prettify-math-mode RET.

Customization

Customize prettify-math-default-scale for formula scale

Set delimiter before this module loaded.

Code example in init.el:

(setq prettify-math-delimiters-alist
  '(("$" tex)
    ("$$" tex block)
    (("\\(" . "\\)") tex block)
    ("`" asciimath)
    ("``" asciimath block)))
(require 'prettify-math)

Existing similar packages:

• latex-math-preview
• preview-latex(px)
• org-latex-impatient
• texfrag
• math-preview

why prettify-math:

• on-fly image generate, no disk temp file
• Responsive style(foreground/background color, size) base on surrunding text.
• JIT render instead of AOT render, which can support large files.
• Not only to support latex math expression, but also asciimath expression, in future other may supported.
• prettify-math implemented as minor mode, make it works in all major modes.
