blc implements Tromp's original IOCCC binary lambda calculus virtual machine in assembly. This lets us replace calloc() with push. That enables it to run faster and use less memory. Read https://justine.lol/lambda/ for further details.

You may install blc as follows on any Linux AMD64 computer:

make
doas make install PREFIX=/usr/local

Here's how to print an ASCII diagram of a Hilbert space filling curve:

{ cat prog/hilbert.blc; printf 123; } | blc
