README.md

this project converts a very small subset (integers and control flow) of WASM to PostScript so you can run it on the printer

corporate implementations target web browsers, servers, crabs, but none target the untapped potential of the shitty PostScript interpreter your printer has

Note wasm2ps requires wasm2wat cause I am lazy and to be fair this project should not exist

Usage

Write fib.c:

int fib(int n) {
  return n < 2 ? n : fib(n - 1) + fib(n - 2);
}

int ps_main() {
  return fib(20);
}

clang --target=wasm32-unknown-wasi -O3 -c fib.c 

(wasm2ps:wasm2ps "fib.o" :output "fib.ps")

Now view fib.ps and the value returned by ps_main() will be printed on the single page

Performance

Non existent. The so-called compiler implemented uses the dumbest possible implementation of control flow and looks up every local in a lexical, so combined with a crappy PS implementation and a slow printer processor, you will be waiting about 30 seconds for fib(20).
