# CRUST
This is a hobby project to learn about compilers and language design. I've designed the language to be similar to C and Rust.
Heavily inspired by https://github.com/DoctorWkt/acwj

## How to use
```sh
cargo run # Compile the crust language to assembly, which will be written to out.s
cc -no-pie -z noexecstack -o bin out.s # Use the GNU C compiler to compile and link the assembly code to an executable file
./bin # Execute the produced binary
```
## Run tests
```sh
./runtests.sh
```
If you're on macOS or another non-Linux system, you can run the tests in a
Linux Docker container using the provided `Dockerfile`:
```sh
./docker_runtests.sh
```
## Examples
Some examples of the language
```rust
let c: char;
let str: *char;
fn main(): u8 {
c= '\n'; printint(c);
for (str= "Hello world\n"; *str != 0; str= str + 1) {
printchar(*str);
}
return 0;
}
```
```rust
let a: u8;
let b: u8[25];
fn main(): u32 {
b[3]= 12; a= b[3];
printint(a);
return 0;
}
```
