okp

okp (pronounced like okapi) is a python script that processes .cpy files and generates C++ code.

if the following code makes you happy, okp might be for you:

def weird_multiply(int a, b):
    for i = 0; i < b; i++:
        a *= b
    return a


def main():
    int a, b
    read a, b

    print "WEIRD MULTIPLIED:", weird_multiply(a, b)

status

okp is not a good idea for anyone to use, but try it anyways and let me know what you've built

installation

pip install okp

motivation

i saw vrsperanza's CPY and the light hit me: a language that looks like python but compiles like C. i decided i want to write programs in it. okp is my attempt to write a pre-processor like CPY but in python.

usage

# print c++ source
okp -p file.cpy

# compile code
okp file.cpy

# compile multiple cpy files together
okp file1.cpy file2.cpy

# specify the executable file
okp file1.cpy -o ./a.out

# compile and run 
okp file.cpy -r

# compil and run (stdin is passed to the binary) 
okp file.cpy -ri < input.txt

# compile a hybrid project
okp file1.h file2.cpp file3.cpy -o ./a.out

features

from CPY

Features that okp implements from CPY are:

indentation based bracketing
automatic parenthesization of conditionals
auto variable declarations
return multiple values from functions
automatic variable destructuring
for and rof loop shorthand (to enable, use -for and -rof flags)
known keyword
#raw include directive
disabling auto variable declarations (-ni flag)
compilation of hybrid projects

Features that are not implemented yet:

export project + Makefile

original

Some original features of okp to make it look more pythonic are:

def keyword before function names
block keyword for creating blocks
pass keyword for no-ops
print and raw_input keywords
self keyword
lines that start with IGNORE_CHAR are not pre-processed
triple backticks for multi-line escapes
