Setting guard variables does not prevent default ftplugin/syntax/indent files from running

Question

I want to prevent the default ftplugin/syntax/indent files from running for tex files.

I have a tex.vim in the $XDG_CONFIG_HOME/nvim/ftplugin directory, i confirmed it runs before the default ftplugin/syntax/indent files through :scriptnames, but the default ftplugin/syntax/indent files are still allowed to run unguarded, so for some reason the variables aren't actually being set.

the tex.vim file is as follows:

let b:did_ftplugin = 1
let b:current_syntax = "tex"
let b:did_indent = 1

I have also set vim.g.tex_flavor = "latex" in my init.lua, so it is defaulting to tex and not plaintex.

Answer 1

I assume the buffer is being reloaded after ftplugin, indent, syntax. So the buffer local variables aren't persistent. Splitting the files into the correct ftplugin/syntax/indent dirs fixes the issues, but is somewhat verbose for just wanting to disable the defaults.
