PyPDF2 VS textract

I still haven't needed to do that part in Rust yet, unfortunately. My mother is still using the pypdf-based concatenator I wrote for her years ago.

I did an extremely quick search and am linking this without knowing anything about it.

Pretty much study Python until this Github repo'd Readme makes sense!: https://github.com/py-pdf/PyPDF2

As other posters have said, if you're just generating PDFs, that's doable with minor library support. If you want to open existing PDFs and do anything non-trivial with them, you'll want a mature, powerful PDF parsing library. PDFKit, which is part of macOS is pretty amazing. If you need portability, something like Python's PyPDF2 is probably the best bet. Knowing the Rust community, though, we'll probably get a library at least as good in Rust in a surprisingly short amount of time.

Why are you using PyPDF4 which seems to have no active maintainer and no documentation instead of PyPDF2 which has both?

one of many options

Feel free. I poked around the PyPDF2 code and it seems like reading signatures is something it supports via xfa_form property (GitHub issue where this was discussed; seems to have been closed v. recently) . would probably be a very simple PR provided you knew where to look for that property.

Scan the text inside the .pdf file, and check for any string that matches the pattern of a DOI or an arXiv ID. The text is extracted with PyPDF2 and textract.

And here are some libraries that might pique your interest although they don't strictly answer your question: - tqdm for adding a progress bar on for loops (it comes with useful information like iteration per second and estimated time needed to finish) - alive_progress adds a progress bar like tqdm, but it works even with generators and while loops which I don't think tqdm does. -timebudget, with just a decorator as soon as a function is completed it prints the time taken to execute it - send2trash for sending files to the trash bin instead of permanently deleting them - keyboard for sending keyboard inputs or check if a key is pressed - mouse same as keyboard but with mouse buttons - textract for extracting text from many types of file with a single interface. It supports documents, powerpoint presentations, csv, excels, images, gifs, audio, and many more

Huh. Must have made a mistake posting the original link. Anyway, this is what I meant: https://textract.readthedocs.io
