Are there any real platforms (real platforms doesn’t include Plan 9 ;)), which doesn’t have darwinsys’s file(1)
? Is this actually an issue?

Not that I'm aware, it's more of a packaging/documentation issue than a portability issue. I think virtually all unixes have darwinsys's file(1) (or compatible for OpenBSD) available, but it's not always installed by default.
So, is this an issue at all? This is supposed to be an issue tracker not just a place to contemplate mysteries of life.
Command used in
filetype.lua
:file -bL --mime-type -- '%s'
As usual, POSIX doesn't have long options on
file(1)
and sadly there isn't an equivalent option in POSIX (-i
in POSIX is for something entirely different btw), the other options are also absent.That said https://www.darwinsys.com/file/ is basically the de-facto implementation of
file(1)
on libre unixes (OpenBSD seems to have forked it some years ago) so it's not a big issue but I think it should be noted for packagers.An annoying part is that popen doesn't seems to allow checking the return value, so if you ended up replacing darwinsys's file(1) with plan9port's file(1) you get a broken vis, I think it should check if the output seems like a correct mime type.
