cyberlang - batteries included python bindings for cyber
Installation
pip install cyberlang
Usage
Simply create a CyberVM instance and evaluate a string:
from cyber import CyberVM
vm = CyberVM()
vm.eval("print 'hello world!'")
Want to capture printed output? Override the print
function from Cyber's core
module with a binding.
The decorator generates all the required wrappers and interfaces, and registers everything with Cyber's VM.
from cyber import CyberVM
vm = CyberVM()
@vm.function('core.print')
def _print(string: str):
print(string)
vm.eval("print 'hello world!'")
Alternate techniques for creating callback functions:
# if no module, assume core
# same result as previous example
# this creates function "print2" in the "core" module
@cyber.function('print2')
def _print2(string: str):
print(string)
# if no module, assume core
# if no function name, use existing function name
# this creates function "test" in the "core" module
@cyber.function
def test():
print('core.test')
Or define multiple functions at once using this class-based syntax
# "core" already exists, so add a() and b() to it
class Core(cyber.module('core')):
def a(self):
print('core.test')
def b(self):
print('core.test2')
# create "new_module" and add c() and d() to it
@cyber.module('new_module')
class Module:
def c(self):
print('new_module.test')
def d(self):
print('new_module.test2')
# create module, implicitly named "NewModule" and add e() and f() to it
@cyber.module
class NewModule:
def e(self):
print('NewModule.test')
def f(self):
print('NewModule.test2')
