Autocmd doesn't trigger on symlinked directory

[Marco]

Hi,

I want to trigger a command when a file in a particular directory is saved.
The solution discussed here work in general.

https://stackoverflow.com/questions/20419121/how-to-automatically-run-a-command-after-saving-a-file

However, I run into issues when the directory is symlinked as in
this (as of now unanswered) question:

https://vi.stackexchange.com/questions/25136/autocmd-pattern-matching-symlinked-directory

So basically the issue is that vim resolves the symlink and doesn't
trigger the autocmd. Example:

mkdir -p ~/vim-test/foo
cd vim-test
ln -s foo symlink-to-foo

" in .vimrc:
augroup ft_customhelp
au!
au BufWritePost ~/vim-test/foo/file-* echo "~/vim-test/file_in_foo_was_saved"
au BufWritePost ~/vim-test/symlink-to-foo/file-* echo "~/vim-test/file_in_symlink_to_foo_was_saved"
augroup END

vi ~/vim-test/foo/file-foo
i foo <esc>:w
→ ~/vim-test/file_in_foo_was_saved

rm ~/vim-test/file_in_foo_was_saved
vi ~/vim-test/symlink-to-foo/file-bar
i bar <esc>:w
→ ~/vim-test/file_in_foo_was_saved
# rather than ~/vim-test/file_in_symlink_to_foo_was_saved

How to trigger the autocmd reliably on symlinked directories?

I believe Vim always does always resolve to the final path, so it is not
possible what you want.

Best,

That's unfortunate. Then I'll need to run the commands manually.
Thanks for the quick reply.
