it does not have any dependency to a pdf parsing library, correct? That's a cool way to learn to file format and be able to work around weird pdf file. But what was the motivation to not use a library to do the pdf parsing work? is it the case that there is none available? Nice work!

Correct, PDFSyntax implements everything at the lowest level. You can ignore the HTML visualization and use it as an API to access PDF objects. Why? Because I started a very small tool as a week-end project and I got hooked reading the PDF Specification so it is becoming a general purpose PDF library for Python. I am not familiar with other libraries but I have the impression that mine implements things that are often overlooked in others, like incremental updates.
