A minimal vimrc setup for LaTeX on mac and linux

Vim configuration

You can spend lots of time getting vim setup to your liking, and probably never finish customizing. My suggestion is to start small and stick to the basics before going crazy with plugins. While I've included some plugins, the hope is that you can easily get started with LaTeX with a minimal of effort and/or Googling.

Here is a small section of some of the things I've figured out to have vim working for editing LaTeX files easily.

1. Copy the file below to a file vimrc and start vim vim -u vimrc to use the file. After all your customization if you are happy then save your configuration to ~/.vimrc.

2. You can then start vim and install the plugins using the command :PlugInstall

3. Choose a colorscheme you like with :colorscheme <tab> to see all the options. Once you find one you like just put that command into the vimrc

4. Setting up vimtex to work with a PDF viewer is a little complicated but I have some of the details already included. You don't actually need anything extra to handle editing LaTeX documents.

In another terminal window just run latexmk -pdf -pvc article.tex to have it continuosly compile your document. Then whenever you save your tex file, it'll compile. In fact, vimtex is basically doing this from within vim.

On a Mac, the vimtex plugin seems to work best with Skim in my view. Note, there is some setup required to enable forward/backward search using synctex.

Other useful tips

1. You use the escape key all the time in vim. So it's best to stick it someplace easily to access. I remap the CapsLock key to Escape, since no one ever uses CapsLock

Add the following to your .bashrc or .zshrc file on Ubuntu

setxkbmap -option "caps:escape"

On Mac OSX you can look in the System Preferences > Keyboard > Modifier Keys (bottom of screen)

After a few of the vimtex updates, I had to use the following instead of let g:vimtex_compiler_callback_hooks = ... to avoid syntax errors:

        let g:vimtex_compiler_latexmk = {
          \ 'build_dir' : '',
          \ 'callback' : 1,
          \ 'continuous' : 1,
          \ 'executable' : 'latexmk',
          \ 'hooks' : [function('UpdateSkim')],
          \   'options' : [
          \       '-file-line-error',
          \       '-synctex=1',
          \       '-interaction=nonstopmode',
          \     ],
          \}

It trows an error each time a tex file is opened:

VimTex: Deprecated options(s) detected! - g:vintex_quickfix_latexlog

How could I get rid off it?

I was getting the same error, "VimTex: Deprecated options(s) detected! - g:vimtex_quickfix_latexlog". I just switched the line that had "g:vimtex_quickfix_latexlog" with "g:vimtex_quickfix_pplatex", which is another option given in the manual for the plugin.
