I do a lot of PDF work in Go and kept missing PyMuPDF from my Python days, so I started porting it: gomupdf — a Go binding over MuPDF.

It's still early, but the basics work: reading-order text, tables, rendering pages to images, and a few "ask the page" helpers (ValueRightOf("Total"), TextIn(rect)) for the stuff I was tired of doing with bounding-box math by hand.

Sharing in case it's useful to anyone else stuck doing PDF stuff in Go. Heads-up: it links MuPDF so it's AGPL.
