I'm not sure why suggesting texlive-latexmk would be a good idea. Wouldn't that mean that we are effectively suggesting most of texlive? That seems like a massive installation which many people won't need because they're using pandoc to generate HTML or man pages.

@mimi_vx, @psimons, @sbahling: review reminder

"Suggest" doesn't do anything with zypper usage, except indicate to the user another package which is a useful addition, in this case one of those options is necessary to produce PDFs. Especially zypper with -y will ignore it. Only if the user is at a tty will it be shown.

https://github.com/jgm/pandoc/blob/e5fed51529120067672b840ba80084281761649e/src/Text/Pandoc/PDF.hs#L120 shows the list of latex engines that are supported, and latexmk is the best choice for openSUSE - most of the others do not exist in Factory AFAIK, and latexmk is definitely a good choice engine, as one of the oldest and best supported engines.

Note that PDF is at the https://github.com/jgm/pandoc/tree/e5fed51529120067672b840ba80084281761649e/src/Text/Pandoc level. Not at the next level, "Writer", https://github.com/jgm/pandoc/tree/e5fed51529120067672b840ba80084281761649e/src/Text/Pandoc/Writers . because PDF is used by several of the writers, iirc docx and others.

Anyway, I will send through another request with a more explicitly reason, and I am happy if you want to reject it also because you feel it leads the user down the wrong path. I do get it isnt needed for some use cases of pandoc, and suggesting it could cause the user to download a truckload of unneeded deps.
