Hey people! I want to learn typst, a modern alternative to LaTeX written in Rust.
Typst can incrementally compile the files to PDF.
Ironically, there is no incrementally refreshing PDF viewer afaik. So for direct visual output of my progress, I would like the fastest, smoothest PDF viewer.
If by "nonremovable popup" in Okular, you mean that little toast-like notification in the top-left, that can be turned off in Settings → Configure Okular... → General → "Show hints and info messages".
Not sure, what you mean by "dancing text". I'm using Okular for my Lilypond escapades, which is basically Latex for sheet music, so not a ton of text that could be dancing, but well, it doesn't.
You might be able to improve Okular's (text rendering) speed by tweaking the settings in Settings → Configure Okular... → Performance...
I use the Gnome document viewer, and every time I recompile it automatically refreshes and keeps position etc. I compile with $ luatex <myfile.tex>, not sure if that matters.
No, less has the LESSOPEN variable, which can be used to run input-preprocessors. lesspipe misuses that to run specific tools with specific mimetypes, in this case pdftotext for pdf files. It's basically equivalent to running pdftotext -layout <file.pdf> | less. Though no images, for that the other tools.
