[help] Is there possible way for another plugin to get mainfile path that vimtex finds? about vimtex

[lervag]

for this it finds path of main-file in the project that is to be compiled. I want to use this path in my plugin / script.

If we are in the context of a Vimscript or Lua plugin, then this should be quite easy. The path is available in b:vimtex.tex (or vim.b.vimtex.tex in Lua). This is only available in the VimTeX buffers, of course, so you may want to put some guards, e.g.:

if exists('b:vimtex.tex')
  " Do stuff...
endif

this could be a dumb question to start with but fairly new here. Any help or link to resources in this direction is appreciated.

I wouldn't call this a dumb question, so don't worry.
