Use xdg-open or other env variable for pdf reader

[idlip]

Ik zathura is popular still, but I find https://github.com/ahrm/sioyek to be alot better.

Ik i can edit the script, if possible i would like to package this for nixos.

So some sort of option for pdf viewer like -p <pdf-viewer> or setting xdg-open would be better, nah?

Something like MANGA_CLI_PDF_VIEWER?

I doubt anyone would want to set env variable manually.

Maybe something like manga-cli -o sioyek if there is no argument, then default can be zathura.

Thank you!
