Hi Junling

I've spent a few minutes looking at your pytex repository on github. I'm
impressed by the amount of work you've done, and not surprised that at
present your Python implementation runs slow.

In addition to your implementation in Python, there are roughly similar
implementations in Java and Rust. The Java implementation is not in use,
but is of historical interest. It aimed for 100% compatibility. It ran too
slow for use in production. The Rust implementation has users and is being
actively developed.

Java: https://en.wikipedia.org/wiki/New_Typesetting_System
Rust: https://tectonic-typesetting.github.io/en-US/

Tectonic is a Rust implementation (with changes) of XeTeX. Even if XeTeX is
changing only slowly, the derived work Tectonic is actively developed, see
https://github.com/tectonic-typesetting/tectonic/blob/release/CHANGELOG.md

Finally, https://tug.org/TUGboat/Articles/tb27-0/fine.pdf gives my views
(from 2005) on integrating Python with TeX. It's been a long time since
I've read that article.

I wish you well with your TeX and Python projects.

with kind regards

Jonathan
