Boo is an object-oriented, statically typed, general-purpose programming language that seeks to make use of the Common Language Infrastructure's support for Unicode, internationalization, and web applications, while using a Python-inspired syntax^[2] and a special focus on language and compiler extensibility. Some features of note include type inference, generators, multimethods, optional duck typing, macros, true closures, currying, and first-class functions.

Boo is free software released under the BSD 3-Clause license. It is compatible with both the Microsoft .NET and Mono frameworks.

Code samples

Hello world program

print "Hello World!"

Fibonacci series generator function

def fib():
    a, b = 0L, 1L       # The 'L's make the numbers double word length (typically 64 bits)
    while true:
        yield b
        a, b = b, a + b

# Print the first 5 numbers in the series:
for index as int, element in zip(range(5), fib()):
    print("${index+1}: ${element}")
