Fix Busybox compatibility (or come up with another way to make a POSIX-like env)

[whiteinge]

I used to test this against Busybox installed to a local directory, sandboxed via env -i. I know Busybox isn't exactly POSIX but it's pretty close, and keep the POSIX docs nearby when you're wondering about a particular flag or command. Anyway I can't think of a better way to get a near-POSIX environment set up. (Suggestions very welcome if someone has an idea here.)

It's been a while since I've done that and a few non-compatible things have snuck in. Busybox doesn't seem to have pr (even though it's POSIX), and there's a syntax error (unclosed }) somewhere in the file that Busybox's sh is choking on that dash is otherwise fine with.

So, either:

• Come up with a different way to make a POSIX env for testing and remove mention of Busybox from the README;
• or, Fix Busybox compatibility.

this appears to work for me ( using nix / nix-shell )
nix-shell -p busybox --command "busybox sh -x ./ok.sh-0.3.0/ok.sh [...ect] "
( BusyBox v1.29.3 from nixpkgs-unstable )
&& ||
nix-shell -p curl -p coreutils -p busybox --command " ./ok.sh-0.3.0/ok.sh [...ect] "

in my case [...ect] = list_issues $repo

Anyway I can't think of a better way to get a near-POSIX environment set up. (Suggestions very welcome if someone has an idea here.)

cant say that i know exactly what near-POSIX env might or might not entail tbh !...
anyway your comments wrt better way to setup an env made me think of

booting up the 'core' from tinycorelinux ( uses busybox )
"toolkit" / distro in some vm like qemu
eg: u=http://tinycorelinux.net/9.x/x86/release/distribution_files; k=vmlinuz ; i=core.gz; [ -f "$k" ] || wget "$u/$k" ; [ -f "$i" ] || wget "$u/$i"; qemu-system-i386 -curses -kernel ./$k -initrd ./$i ;

and adding coreutils for pr dep
tce-load -w coreutils.tcz .. its possible to extract the tcz/squashfs create cpio.gz and concatenate with core.gz :D

Thanks for the reply. Nix has been on my list of things to play with for a while. Your comment prompted me to give it a try locally. nix-shell is really slick. I'm going to keep playing around with this.
