Iâve used PDFMiner and pypdf2xml previously and both are easier to use now that Atlas is available. Both work well, though XPdf (in C++) is faster. http://www.unixuser.org/~euske/python/pdfminer/ https://github.com/zejn/pypdf2xml pdf2xml (also Python) is slightly quicker than pypdf2xml but doesnât handle Type 2 fonts properly.

There is a lot of external mature stuff out there and we can gain users from there if we make bridges to the stuff they already know and use. For example, I would like to try the Pharo-Chrome integration and also the Hypothesis JSON API to annotate and read PDF/HTML.

But as long as we donât have a way to natively display interactive multimedia (maybe Bloc will at some point support something like this?), I consider it not worth the effort to come up with a half-baked (note to self: watch that movie again) solution that is hard to implement and cannot even remotely support all the use cases as an external tool that have been crafted for years. Just rendering bitmaps loses so much information (full text) and actionability (hyperlinks). If I wanted to have interactive PDFs inside Pharo, I had to invest so much time to replicate functionality that has been implemented before. So, I chose the path of the least resistance by pushing this responsibility to a specialized tool. I think Pharo is great for modelling, exploration, and inspection, but OS integration is not really a selling point, and it doesnât have to be. By using a standard PDF viewer I also gain that users are already familiar with them and have their own workflow that I can extend. As a side note, I think that being able to embed a web browser inside Pharo would open up a whole new world of applications, as web browsers are currently the vehicles for content distribution. But as long as there is no project where this is a critical feature, I can live without it.

There are ton of converters out there that can do this.

For me, the corpus of scientific papers form an interconnected graph, not those plain lists and tables we keep in our bibliographies. So, here is the first prototype that has Google Scholar integration for search, can fetch PDFs from IEEE and ACM, extracts metadata from PDFs - all this results in hyperlinked PDFs! See a demo here: https://youtu.be/EcK3Pt_WnEw Also slides from the SCG seminar here: http://scg.unibe.ch/download/softwarecomposition/2017-10-31-Leuenberger-ILE.... I plan on packaging it, so that those who are interested can check it out themselves (help wanted!). Currently, it only works on macOS. What do you think of my approach? Which use cases should be added? Cheers, Manuel
