## What is pisces?
I wanted to learn how to write a compiler in Haskell using parser combinators.
So pisces is a very basic programming language with the syntax inspired a little
bit by the Rust programming languge. The compiler provided in this repository
targets LLVM and emits LLVM assembly language.
A simple pisces program looks like this (extern functions calls are not yet
implemented, so no "Hello World" ):
```rust
fn add(a: i***, b: i***) -> i***
{
var c: i*** = a + b;
return c;
}
fn main () -> i***
{
return add(4, 5);
}
```
## Usage
In order to build it you need LLVM 5.0. From here it's just `stack build`.
Compile and run a program:
```
stack exec pscsc main.pscs
llvm-as a.ll
lli a.bc
```
To build a native executable:
```
...
llc -filetype=obj a.bc
clang a.o
./a.out
```
