This is a quick and dirty Python module that embeds mruby. It has basic constraints around mruby's eval() call including a memory and execution time watchdog.
Building this module requires some slight tweaks to mruby. After cloning the repository, pull in the submodule by running
git submodule update --init
Next, compile mruby
cd mruby && make
Now you're ready to build and install the module
python setup.py build
python setup.py install
If all goes well, you should be able to run a few minimal tests
./test.py
