it doesn't do everything you want (actually, it doesn't do most), but
iirc it has not been touched since the advent of Pd-on-OSX.

but on android you are most likely using libpd and therefore have yet

why would you want to do that?
even microsoft allows using forward slashes in fopen()/open() and in any
case, Pd (sh)would do any necessary conversion on the C-level (that is:
you tell [textfile] to open "foo/bar.txt" and it will convert it to
"foo/bar.txt", "foo\bar.txt" or "foo:bar.txt" depending on whatever is
required to open the file.
the patch doesn't need to know at all.

so i think that the primary goal should be to make this functionality
a patch should run on *all* implementations of Pd, without adapting
platform specific quirks to guarantee consistent behaviour through all
platforms are in the realm of the implementation of the interpreter.
having said that, i still see the need for that functionality and
support the idea for such an object (after all, that's why i wrote
[operating_system], though i cannot remember having used it _ever_).
though the output shall be uniform, an dwe need much more info, like
ptr-size and whatnot.
something like [uname], with some Pd-specifics like flavour, and *version*.
and i think we should go for messages that only report a single thing,
rather than outputting long lists (that keep growing the more system
information we want to add).
[version, flavour, os(
[route version flavour os]

PS: so what's the OS on Debian/kFreeBSD?
