🧪 Getting started with Codon

Install Codon

Run the following shell command in your terminal to install Codon:

/bin/bash -c "$(curl -fsSL https://exaloop.io/install.sh)"

Run your first program

Save the following code to file fib.py:

from time import time

def fib(n):
    return n if n < 2 else fib(n - 1) + fib(n - 2)

t0 = time()
ans = fib(40)
t1 = time()
print(f'Computed fib(40) = {ans} in {t1 - t0} seconds.')

Run the program in Codon:

codon run -release fib.py

Compile to an executable:

codon build -release -o fib fib.py

Run the executable via ./fib.

Use Codon's "just-in-time" (JIT) compiler

Install Codon's JIT with pip:

pip install codon-jit

Save the following code to file primes.py:

import codon
from time import time

def is_prime_python(n):
    if n <= 1:
        return False
    for i in range(2, n):
        if n % i == 0:
            return False
    return True

@codon.jit
def is_prime_codon(n):
    if n <= 1:
        return False
    for i in range(2, n):
        if n % i == 0:
            return False
    return True

t0 = time()
ans = sum(1 for i in range(100000, 200000) if is_prime_python(i))
t1 = time()
print(f'[python] {ans} | took {t1 - t0} seconds')

t0 = time()
ans = sum(1 for i in range(100000, 200000) if is_prime_codon(i))
t1 = time()
print(f'[codon]  {ans} | took {t1 - t0} seconds')

Run with Python:

python3 primes.py
