When I used to use a PC I was familiar with py2exe, the mac equivalent I saw most people talking about was py2app — which compiles python to .app files, not .exec files. I was familiar with compiling C files to execs on mac, and I had heard of cython (but I had never used it before), so I figured I could write something to go from python to cython to an exec. I initially did not write this for anyone else to use — but now I'm thinking about packaging it as a pip module.

This is my first time building a command line tool for executing shell commands and messing with files and directories.

"""(PYCX) PYthon to Cython to eXec, a unix command line util
Usage:
 pycx FILES... [-o DIR --show --delete --run]
 pycx --help

Options:
 FILES one or more python files to compile
 -o --output=DIR output directory
 -s --show show output from exec compiling
 -d --delete delete the c file after compiling exec
 -r --run run the exec after compiling
 -h --help show this screen.
"""
import os, re
from docopt import docopt

args = docopt(__doc__)

# the two pathnames below tell gcc where python is so that cython can be compiled to an exec
INCLUDES = '/usr/local/opt/python/Frameworks/Python.framework/Versions/3.7/include/python3.7m'
LIBRARY = '/usr/local/Cellar/python/3.7.2_2/Frameworks/Python.framework/Versions/3.7/lib'
HIDEDATA = '&>/dev/null' # this is used to hide output while compiling C files

for pyFILE in args['FILES']:
 if pyFILE.endswith('.py'): # file must be a python file
 path, name = os.path.split(pyFILE) # split full path to seperate path & filename

 cFILE = re.sub('.py$', '.c', pyFILE) # name of the file with .c extension & path
 FILE = re.sub('.py$', '', name) # name of the file with no extension or path

 PATH = path + '/' if path is not '' else '.' # if in current directory, path = '.'
 OUTPUT = args['--output'] + '/' if args['--output'] else '' # blank if no arg given
 SHOW = HIDEDATA if not args['--show'] else '' # will hide gcc output if SHOW is false
 # this command will be used to delete the C file
 DELETE = f'find PATH -name "FILE.c" -type f|xargs rm -f' if args['--delete'] else ''
 RUN = f'./OUTPUTFILE' if args['--run'] else '' # command to run the exec

 commands = [ # cython to make C file, gcc to compile to exec, and some options
 f"cython --embed -o cFILE pyFILE", # convert python to cython C file
 # compile cython C file to exec file
 f"gcc -v -Os -I INCLUDES -L LIBRARY cFILE -o OUTPUTFILE " + 
 # source python & other options -- hide or show, delete C file, run exec
 f"-lpython3.7 -lpthread -lm -lutil -ldl SHOW", f"DELETE", f"RUN"
 ]
 for command in commands:
 os.system(command) # execute commands above, excluding blank commands
 else:
 print(__doc__) # show the help menu if user doesn't put a python file

Besides modifying INCLUDES and LIBRARY to work with varying path locations, are there any other major problems preventing this from working as a python module? Does this even seem like a tool some people might use?
