Add support for .tex // Doesn't work for snippets in .tex files

[qazip]

Hello,

I'm trying to use nvim-completion-manager with .tex but it doesn't seem to work for snippets in .tex files, or is there some problem in my config?

This is my minimum vim file:

call plug#begin('~/.vim/plugged')

Plug 'roxma/nvim-completion-manager'
Plug 'SirVer/ultisnips'
Plug 'honza/vim-snippets'

call plug#end()

imap <expr> <tab>  (pumvisible() ?  "\<c-y>\<Plug>(expand_or_nl)" : "\<tab>")
imap <expr> <Plug>(expand_or_nl) (cm#completed_is_snippet() ? "\<C-j>":"\<tab>")
inoremap <expr> <Down> pumvisible() ? "\<C-n>" : "\<Down>"
inoremap <expr> <Up> pumvisible() ? "\<C-p>" : "\<Up>"

let g:UltiSnipsExpandTrigger = '<C-j>'
let g:UltiSnipsJumpForwardTrigger = '<C-j>'
let g:UltiSnipsJumpBackwardTrigger = '<C-k>'

It works for .latex but not for .tex

You probably need to add to your vimrc:

let g:tex_flavor='latex'

Please read :h ft-tex-plugin:

If the first line of a *.tex file has the form >
    %&<format>
then this determined the file type:  plaintex (for plain TeX), context (for
ConTeXt), or tex (for LaTeX).  Otherwise, the file is searched for keywords to
choose context or tex.  If no keywords are found, it defaults to plaintex.
You can change the default by defining the variable g:tex_flavor to the format
(not the file type) you use most.  Use one of these: >
    let g:tex_flavor = "plain"
    let g:tex_flavor = "context"
    let g:tex_flavor = "latex"
Currently no other formats are recognized.

This typically affects empty tex files (you start a new manuscript) or chapter tex files which do not have the line \documentclass.

Oh, it seems to work fine on a non-empty tex file. My bad! Thank you @kiryph
