Mathup: A Speedy Math Expression Parser

Mathup is a lightweight tool that translates simple mathematical expressions written in an AsciiMath-inspired markup language into structured MathML. Faster than MathJax because it only parses and translates, leaving rendering to the browser, Mathup supports a wide range of mathematical symbols and functions, including fractions, subscripts/superscripts, matrices, and tensors. It offers extensive customization options for fonts, colors, and backgrounds. Developers can use it in the command line, on a server, or in a browser for quick and efficient math expression handling.
