Technical Implementation of DOOM PDF
PDF JavaScript Support
The PDF file format supports Javascript with its own separate standard library. Modern browsers (Chromium, Firefox) implement this as part of their PDF engines. However, the APIs that are available in the browser are much more limited.
Implementation Details
It turns out that old versions of Emscripten can compile C to asm.js code that will happily run inside the limited JS runtime of the PDF engine. The project utilizes doomgeneric, a fork of the original Doom source, as it simplified the IO implementation process. The only requirements were implementing a framebuffer and keyboard inputs.
Display Technology
Unlike previous interactive PDF demos, the output for DoomPDF is achieved by creating a text field for each row of pixels in the screen, then setting their contents to various ASCII characters. This innovative approach results in a 6 color monochrome display, capable of updating at reasonable speeds (80ms per frame).
Source Code & Compatibility
