Currently I am preparing the text for a paper (together with two coauthors) where we cite help from MO on two occasions. I am doing this using the cite button. It works correctly both in Acrobat and SumatraPDF, i. e. leads to the correct place when clicked from inside pdf. However when I do it in...
@MartinSleziak no idea with just that information, if you made a real example and posted as a question here someone could look into the generated pdf and se what the link annotation says.
@MartinSleziak that can't work. If you put simply URL: https://mathoverflow.net/q/313198 in a document, then it depends on the pdf viewer how the link is interpreted. The OP needs something like URL: \url{https://mathoverflow.net/q/313198} or should use biblatex and the url field. (and the document should load hyperref.)
We'll see whether there will be some further response in that room.
@UlrikeFischer So does it mean that the bibtex entry generated by the cite button on Stack Exchange sites in incorrect? Should it have something like eprint={\url{https://mathoverflow.net/q/313198}} instead of eprint={https://mathoverflow.net/q/313198}?
@MartinSleziak depends on if you use biblatex or not. With biblatex the first is wrong and the second okay, without biblatex it depends on the bib-style.
So what is actually the part which is incorrect in the OP's example? Is it this part: note={URL: https://mathoverflow.net/q/313198 (version: 2018-10-19)}?
@MartinSleziak without context impossible to say, that will cause latex to generate latex using \url which is undefined by default but if it is used with a document using hyperref then it will make a link, so having \url is probably what you want but if you are writing a generic tool to make bibliographies that work with any latex document not using hyperref might be what you have to do, and as Ulrike says if the bibliography is being used with biblatex the details are different again.
@MartinSleziak I am very grateful for your efforts. I will try to make an mwe and post to tex stackexchange. Let me say however that most likely the problem is with the gmail pdf viewer rather with tex, since the pdf I generate contains correct link, and when I click on it from within either Acrobat or SumatraPDF, everything works correctly. Only when I click in a browser from within the gmail pdf viewer the problem occurs.
I've now got an answer on TeX.SE. I believe it indicates that the amsrefs entry generated by the MO system needs an \url command and the hyperref package to work properly, but I am not sure.
