Surely implementing the shell commands natively is the way to go? This way you then have to parse the output of ifconfig, say. eg I have been doing this for Lua [1] you can do > i = nl.interfaces() > print(i.lo) lo Link encap:Local Loopback inet addr: 127.0.0.1/8 inet6 addr: ::1/128 UP LOOPBACK RUNNING LOWER_UP MTU: 16436 RX packets:261454 errors:0 dropped:0 TX packets:261454 errors:0 dropped:0 > print(i.eth0.macaddr) f0:da:f0:38:36:39 The functionality is now reasonably comprehensive, so you can rename interfaces, add addresses, although it is still a work in progress, as there is a fair amount of work involved as there is a lot of shell to implement, but it can be incrementally useful.

I have been working on [1] a Lua library that can implement all the functionality to do what is needed to bring up a Linux userspace. I should have a very minimal bootable environment very soon, as I have enough of the network tools, mount and so on implemented to put it together. There is not really intended to be a shell and command line tools though, it is just a library but you could have a REPL console. I am more interested in easily creating small system images to run single applications in, see [2] for rationale, building small testable whole system images that are quick to rebuild. Planning to use Musl libc [3] which is small and easy to debug so you can easily follow what is going on, plus the whole userspace will be BSD licensed.

for the comments: that's a matter of taste, IMHO. for bitwise ops: look at 5.2, it has it now. 32-bit operations. floating point arithmetic: in practice, I haven't seen it as a problem as soon as I stay within the 32-bit range - then the numbers can be represented exactly, so the abstraction works well. OOP: can't say for it, I did not do it much. For the "fast" - check luajit (http://luajit.org/) - it is near-native speed while remaining reasonably slow. And the FFI in luajit is simply fantastic. Take a look at https://github.com/justincormack/ljsyscall which binds the syscalls. The annoyance that I'd thought of is that the array indexing starts with one, not zero - this brings some headaches during the index calculations. But this also forces to rethink the logic to use more of iterators, and abstract away from the indices. So, after al
