How to (more reliably) recognize the end of sentences in LaTeX?

Question

Movement and actions using ) and ( are very powerful: I use them all the time. However, when writing and editing LaTeX, I have run into the following problem: vim cannot recognize the end of some LaTeX sentences. For example:

This is a test. This is only a test. Instead, according to Gottlieb, Socrates
has two audiences, the in-crowd and the outsiders.\footcite[][278]{gottlieb-1992}
The in-crowd know what Socrates means, but Socrates deceives the outsiders. I am
still testing. Test?\footcite[Blah, blah][456]{gottlieb-1992} Moar testing.

Can you see it? The end of the first sentence is, well, kind of at outsiders., which is right before \footcite. But really the sentence ends after the citation {gottlieb-1992}. Either way, it's a moot point: vim thinks that the third and fourth sentences are one sentence. The same goes for the last two sentences: vim sees them as one sentence. The problem, I think, is that the end of sentence (. or ?) is hidden by \footcite.

tl;dr: sentence endings in LaTeX can involve citations after the final punctuation. As a result, vanilla {neo,}vim cannot handle them. Does anyone know of a trick or a plugin to help vim deal with them?

Answer 1

There is a plugin that helps: vim-textobj-sentence. It replaces vim's built-in ) and (, and it does a better job on many LaTeX sentences. However, it also has some issues of its own. For example, it doesn't recognize sentences within parentheses. (I'm putting this here for people who find this question via Google, but I'm not going to accept this answer yet.)

Answer 2

That depends on what causes Vim to think that the sentence ends at another spot than what you intend. You could have a look at the csquotes package. http://ftp.lyx.org/pub/tex-archive/macros/latex/contrib/csquotes/csquotes.pdf
