"stat: illegal option -- - dated" on macOS

[rpdelaney]

BSD stat is a very different beast than GNU stat, and BSD stat ships on macOS. My guess is that's somewhere at the root of this error.

I honestly don't know how long this has been going on, since the plugin works fine otherwise and I may not have noticed at all. It's no kind of big deal.

Hi, I suppose this line is the error? https://github.com/chrisbra/Recover.vim/blob/a6f8d9e6086e611daf55f3fe05c06e7aaaf46f35/autoload/recover.vim#L45

Looks like it. Here's the output on my macbook using the built-in BSD stat vs GNU stat (which is gstat when installed with homebrew):

$ /usr/bin/stat --printf="%U\n%Y\n" pyproject.toml
/usr/bin/stat: illegal option -- -
usage: stat [-FLnq] [-f format | -l | -r | -s | -x] [-t timefmt] [file ...]
$ gstat --printf="%U\n%Y\n" pyproject.toml

I'm not sure what would be the best way for vim-recover to detect which one is on the system, though.

hm, interesting. I tried to pull a freebsd docker image and it had gnu stat installed :)

Okay, how about the following patch then:

I saw the commit message. To do this with BSD stat, try:

$ stat -f "%Su\n%m\n" .bashrc

ah thanks. I couldn't bend my brain across those printf expandos that night :)

I included your change, hopefully it works.
