Viewing with okular using temp files broke

[rolandherzog]

Description

I am using vimtex in nvim-qt with okular as a viewer and latexmk backend. A minimal init.vim to reproduce the issue is as follows.

call plug#begin('~/.cache/nvim/plugged')
Plug 'lervag/vimtex'
call plug#end()

let g:vimtex_view_general_viewer = 'okular'
let g:vimtex_view_use_temp_files = 1

Expected behavior

Issuing :VimtexCompile, e.g., on a file named test.tex, produces test.pdf. Upon successful compilation, test.pdf is copied over to test_vimtex.pdf, which is the file opened by issuing :VimtexView. This used to work until recently (c72d34b ?)

Actual behavior

test.pdf is created but it is not copied to test_vimtex.pdf. Issuing :VimtexView results in a Viewer cannot read PDF file! error.

Sorry, that was a silly regression bug introduced while doing some refactoring work. I think it is fixed now. Please test.

Thanks for your quick reply. I believe this does not fully fix the issue though. Still, test.pdf is not copied to test_vimtex.pdf after a successful compile run. Consequently, okular, which displays test_vimtex.pdf, does not refresh. The file test.pdf is only copied over to test_vimtex.pdf once I issue :VimtexView (or perform a forward search).

I've made some further changes that I think solves your issue. Can you update and test?

[rolandherzog]

Yes indeed, the issue is now fixed and the behavior as expected. I appreciate your quick help!

Great; thanks for noticing and reporting the problem!
