In a groundbreaking project, Ading2210 developed DoomPDF, enabling Linux to run within an interactive PDF file through a JavaScript-based RISC-V emulator. While the execution is notably slow and primarily functional in Chrome, users can type commands and use tools like vi text editor directly in the PDF. This innovation opens vast possibilities for more interactive PDFs, allowing for user input and calculations, but it also raises security concerns about potential embedded operating systems in shared documents.
Once the kernel loads, you wind up at a terminal prompt, where you use the on-screen keyboard to type a command. It's slow, but you can run quite a few Linux commands -- all from within a PDF.
Imagine a PDF with computational power. This could mean even more interactions with PDFs. Think about it. You could create a PDF that accepts user input, calculates figures, or even includes automation.
