nock
|
|
====
|
|
|
|
nock is our machine code.
|
|
|
|
nock is a homoiconic combinator algebra, not much fancier than SKI
|
|
combinators. The spec fits on a T-shirt and gzips to 340 bytes.
|
|
|
|
Think of nock as a kind of functional assembly language. It's not like
|
|
assembly language in that it's directly executed by the hardware. It is
|
|
like assembly language in that:
|
|
|
|
- Everything in Urbit executes as nock.
|
|
- You wouldn't want to program directly in nock.
|
|
- Learning to program directly in nock is a great way to start
|
|
understanding urbit from the ground up.
|
|
|
|
Just as Unix runs C programs by compiling them to assembler, Urbit runs
|
|
Hoon programs by compiling them to nock. You could try to learn Hoon
|
|
without learning nock. But just as C is a thin wrapper over the physical
|
|
CPU, Hoon is a thin wrapper over the nock virtual machine. It's a tall
|
|
stack made of thin layers, which is much easier to learn a layer at a
|
|
time.
|
|
|
|
And unlike most fundamental theories of computing, there's really
|
|
nothing smart or interesting about nock. Of course, in a strictly formal
|
|
sense, all of computing is math. But that doesn't mean it needs to feel
|
|
like math. nock is a simple mechanical device and it's meant to feel
|
|
that way.
