'''

This is a helper tool which is designed to make it possible

for other apps to read emscripten's configuration variables

in a unified way. Usage:

em-config VAR_NAME

This tool prints the value of the variable to stdout if one

is found, or exits with 1 if the variable does not exist.

'''

import os, sys, re

from tools import shared

if len(sys.argv) != 2 or \

not re.match(r"^[\w\W_][\w\W_\d]*$", sys.argv[1]) or \

not (sys.argv[1] in dir(shared)):

print 'Usage: em-config VAR_NAME'

exit(1)

print eval('shared.' + sys.argv[1])
