GitHub - desgeeko/pdfsyntax: A Python PDF parsing library and tool built on top to browse the internal structure of a PDF file

The project is focused on chapter 7 ("Syntax") of the Portable Document Format (PDF) Specification. PDFSyntax is lightweight (no dependencies) and written from scratch in pure Python. It is mostly made of simple functions working on built-in types and named tuples. Shallow copying of the Doc object structure performed by pure functions offers some kind of - experimental - immutability. PDFSyntax favors non-destructive edits allowed by the PDF Specification: by default incremental updates are added at the end of the original file. This is ALPHA quality software.
