huckle

huckle is a simple dynamic programming language that aims to be easy to use and similar to Python.

Variables behave the same as in Python: they don't have a value until one is assigned to them. The default types are numbers, strings, booleans and None.

x = 10
y = 20
z = x * y # 200

a = 2 ^ 3 # 8
b = 5 / 3 # 1.67
c = 10 % 3 # 1

message = "Hello " + "world"
print(message)

# Chained comparison operators!
condition = 5 > 3 == 3 # True
print(not_initialized_yet) # None

Shortcuts exist to quickly change and delete variables.

x = 10
x += 20 # 30
# Assigment operators are expressions!
print(x -= 10) # 20

del x
print(x) # None

After each section, indentation is needed. The conditional sections act the same as in Python. You can create loops with the while section.

if 10 >= 4:
    print("This is true")
elif 10 < 0:
    print("Would be kind of weird if this is true")
else:
    print("Well I guess it's this then.")

x = 10
while x > 3:
    print(x)
    x--

Functions are expressions, but are defined using blocks. Putting infix in front of your function definition makes it an infix operator. If not enough arguments are given, the function is curried.

say_hello = fn(name):
    print("Hello", name)
    
say_hello("world")

root = infix fn(r, x):
    return x ^ (1 / r)
# Infix functions are functions with two arguments.
# The function can be put between the arguments.
print(3 root 8) # 2

sqrt = root(2) # Curried function!
print(sqrt(100)) # 10

Matrices are the way to go for list implementation, but also for easy 2D arrays. If only one row is present, the matrix acts as a list. Split elements by using , and split rows using ;.

matrix = [1, 2; 3, 4]
transpose(matrix) # [1, 3; 2, 4]
