I'm using LaTeX in Vim with plugins vimtex from lervag (GitHub link), latexmk and neovim, and it works just fine as long as I'm making no mistakes.

I press \ll and compile by writing (:w) and the pdf is updated if there is no mistake; however, if I have an error in my code, the pdf just does not update, and I get no error message or anything. I checked Vim :messages, and nothing there either...

Does anyone know how to have a compilation log with these plugins (or if I should add another plugin), or at least a way to diplay error messages (and maybe warnings)?

Thanks in advance!

  • Did you try opening the compiler quickfix window? (try help copen) – Thruston Jul 21 '18 at 22:41

    or using the \le command to parse the error log? (as mentioned on that link you give...) – Thruston Jul 21 '18 at 22:43

    \le command is what I was looking for, thank you so much! I need to get better at reading REAMEs... Problem solved! – Ul Tome Jul 23 '18 at 9:34
  • Good. But I think we should probably close this question as off topic for TEX.se – Thruston Jul 23 '18 at 9:35

The vimtex plugin populates the quick fix view with the errors. It should actually open automatically (by default) in a bottom split-window. It is weird that it does not for you. Invoking :copen directly should open the window. Also [q and ]q should let you iterate between errors (but this does not work very well for latex as it is hard to filter spurious and non-spurious messages in the log; LaTeX's log is a mess, in comparison to most compilers).

The best way is to use \le, and here is a full list of command of vimtex (from the official document)

And if you forgot them when you're using vim, you can actually type :nn when editing a tex file to see the same thing The result of typing :nn
