This is why I use LuaLaTeX for this: https://github.com/WillAdams/gcodepreview/blob/main/literati.sty https://github.com/WillAdams/gcodepreview/blob/main/literati... which allows me to have an ordinary .tex file: https://github.com/WillAdams/gcodepreview/blob/main/gcodepreview.tex https://github.com/WillAdams/gcodepreview/blob/main/gcodepre... which outputs multiple .py and .scad files and generates a .pdf with nice listings-based code blocks, ToC, index, hyperlinks, &c.: https://github.com/WillAdams/gcodepreview/blob/main/gcodepreview.pdf https://github.com/WillAdams/gcodepreview/blob/main/gcodepre... The notable downsides are that the .sty and .tex files have to be customized for the filenames which one can output, and I haven't been able to get auto-line numbering working between code blocks, so one has to manually manage the counters.
