NeoTex
This plugin compiles latex files asynchronously while edditing.
The PDF output gives a live preview of your document as you type.
You have the option to highlight changes from the previous save using latexdiff.
Update: Now working on NeoVim and Vim 8
live preview of a latex document
live preview with latexdiff
Installation
Install using the plugin manager you like.
For example vim-plug:
Plug 'donRaphaco/neotex', { 'for': 'tex' }
Usage
For live previewing your latex file open the created PDF using a PDF viewer which supports auto reloading (I recommend zathura or evince). The PDF is created in the same folder where your latex file is stored.
Options
| Option | Default | Description |
|---|---|---|
g:neotex_enabled | 1 | 0 = always disabled, 1 = default off, 2 = default on |
g:neotex_delay | 1000 | Update intervall in milliseconds |
g:neotex_latexdiff | 0 | enable latexdiff |
g:neotex_latexdiff_options | - | additional options for latexdiff |
g:neotex_pdflatex_add_options | - | additional options for pdflatex (-jobname=<filname> and -interaction=nonstopmode is always set) |
g:neotex_pdflatex_alternative | - | alternative for pdflatex (e.g. xelatex or lualatex) |
g:neotex_subfile | 0 | experimental support for subfiles (#8) (latexdiff won't work if enabled!) |
I also recommend setting let g:tex_flavor = 'latex', which can prevent some issues. (see :h g:tex_flavor for information)

| Command | Description |
|---|---|
:NeoTex | Compile current buffer (asynchronously and without writing the file) |

Tipp
For better performance use a precompiled preamble.
