Twit 🐦

A simple, fast compiled programming language powered by LLVM.

Features

• Simple syntax inspired by C and Python
• Static typing
• Native compilation via LLVM
• print << and input >> built-in I/O
• Garbage Collection (Boehm GC)
• import math support

Installation

Linux

git clone https://github.com/onecu-21/twit
cd twit
mkdir build && cd build
cmake ..
make -j$(nproc)
sudo cp twitc /usr/local/bin/twit

Windows

Use WSL (Windows Subsystem for Linux) 🙂

macOS

Untested... I think it will work... maybe...

Usage

twit hello.twit -o hello
./hello

Syntax

Variables

new int x = 5
new float y = 3.14
new double z = 3.141592653589793
new long l = 9999999999
new bool b = true
new string s = "hello"
new int arr[10]

Functions

function add(int a, int b) = int {
    return a + b
}

Print & Input

print << "hello world"
print << x

new int x
input >> x

Operators

x++  x--  ++x  --x
x += 1  x -= 1  x *= 2  x /= 2
x % 2

Control Flow

if (x > 0) {
    print << "positive"
} else if (x == 0) {
    print << "zero"
} else {
    print << "negative"
}

while (x > 0) {
    x--
}

for (new int i = 0; i < 10; i++) {
    if (i == 5) { break }
    if (i == 3) { continue }
    print << i
}

Import

import math

function main() = int {
    new double x = sqrt(2.0)
    new double y = pow(2.0, 10.0)
    print << x
    print << y
    return 0
}

Available math functions

• sqrt, sin, cos, tan
• log, log2, floor, ceil, round
• pow, fmod, fabs

Structs

struct Point {
    int x
    int y
}
