Feature: go to label

[petRUShka]

Minimal working example

\documentclass{minimal}

\usepackage{amsmath, amstext, amsfonts, amssymb, amsthm}


\begin{document}

\begin{equation}\label{eq:equation}
1 + 1 = 2
\end{equation}

...

Some text with \eqref{eq:equation}.

\end{document}

I want to place cursor on \eqref{eq:equation} press Ctrl+] and go to definition of eq:equation (e.g. to line with \label{eq:equation}).

It is very convenient and it is a VIM way of exploring any document including VIM-help.

Possibly ctags should help. There is a discussion on SoF about it and one more and blog post on subject.

P.S. Please don't focus on equations, any other labeled items (theorems and etc) should be covered and also cited items too (bibliography items).

FYI: universal CTAGS seems to work just fine in this MWE (a more maintained ctags). Type :tags filename.tex, then ctrl+] works as expected. Also, even without tags there is the built in gd goto definition family of mappings, although these don't always work.

I am not sure I want to add anything to vimtex for this. Tags are an inherent part of Vim and should work out of the box.

There exists plugins such as gutentags for automatic generation/updating of tag files. I could add a minor entry in the docs to suggest such plugins?

Also, I could update the iskeyword option to include :. This would allow CTRL-] on eq:equation.

I think proper instruction "How to enable tags" should be very useful! As well as updated iskeyword.

Let me know what you think about the update to the docs. Perhaps one should add more info than this? I'd prefer a good reference, though, instead of writing too much in the docs.

Looks good enough. But universal-ctags seems not to support *.bib files. So it is needed additional configuration. I placed following code borrowed from that answer in ~/.ctags and it works fine:

--langdef=bib
--langmap=bib:.bib
--regex-bib=/^@[A-Za-z]+\{([^,]*)/\1/b,bib/   

Possibly it can be noticed in docs too.
