specific settings in after/ftplugin/fortran.vim not working

Question

My after/ftplugins/fortran.vim has the following lines

let fortran_fold=1
let fortran_fold_multilinecomments=1
set foldmethod=syntax foldlevel=1 foldnestmax=2
let fortran_free_source=1
let fortran_do_enddo=1

If I open a fortran file, I don't see folded code, but when I change foldmethod to indent it works and I see code folded based on indentation.

The same settings work if I put them in init.vim . I also have

syntax on
filetype indent plugin on

in my init.vim .

Answer 1

Nvim enables filetype plugin indent on and syntax on by default ( :h nvim-defaults ). So, just nvim test.for (without any init.vim ) would do the right thing.

But when doing it manually, the order does matter! This is correct:

filetype plugin indent on
syntax on

Vim suffers the same issue.
