Inverse search doesn't work until reload plugin with `\lx`

[user202729]

Currently, the inverse search logic in autoload/vimtex/view.vim has

  " Only activate in relevant VimTeX projects
  let l:file = resolve(a:filename)
  let l:sources = b:vimtex.get_sources()
  if vimtex#paths#is_abs(l:file)
    call map(l:sources, {_, x -> vimtex#paths#join(b:vimtex.root, x)})
  endif
  if index(l:sources, l:file) < 0 | return -2 | endif

which does nothing if the file is not in the source list.

However, the problem is I'm using inkscape-figures https://github.com/gillescastel/inkscape-figures , so the source list regularly changes (every time I add a figure, another .pdf_tex file is added to the source list), but this change is not picked up until late (e.g. \lx pressed).

Do you see a good solution for this issue?

What I can think of:

• re-parse the source file on inverse_search (is this too slow?)
• make a configuration option to set a whitelist e.g. "if the relative path starts with figures/ then always allow"
• make a key binding to reparse source file for list of source files (clumsy but probably work? :VimtexReloadState sort of do this but it also stops the compiler…)

I think this is a good solution. I've pushed an update that should refresh the source list on inverse search. I don't think it should be too slow, but I'll be glad to hear it if I'm wrong.
