Show HN: I am building a new Python library to read/write PDF files
As others have already written, there are many slightly invalid PDF files out there in the wild that many readers can display mostly fine and which your library should also be able to handle.
If you can, grab yourself a copy of the most recent PDF 2.0 specification since it contains much more information and is much more correct in terms of how to implement things. Also have a look at the errata at https://pdf-issues.pdfa.org/32000-2-2020/index.html.
As I'm implementing a PDF library (in Ruby), I have started to collect some situations that arise in the wild but are not spec-compliant, see https://github.com/gettalong/annotated-pdf-spec. That might help you in parsing some invalid PDFs
What are some alternatives?
pdfquery - A fast and friendly PDF scraping library.
i7j-rups - RUPS is an acronym for Reading and Updating PDF Syntax. RUPS is a tool built on top of iText® that allows you to look inside a PDF document and browse the different PDF objects and content streams.
pdfsyntax - A Python library to inspect and modify the internal structure of a PDF file
PyMuPDF - PyMuPDF is a high performance Python library for data extraction, analysis, conversion & manipulation of PDF (and other) documents.
polyfile - A pure Python cleanroom implementation of libmagic, with instrumented parsing from Kaitai struct and an interactive hex viewer
betterwrite - :bookmark_tabs: A Creative Word Processor.
pandoc - Universal markup converter
mupdf - mirrored from git://git.ghostscript.com/mupdf.git
