Maybe this is what you are looking for: How do i run the python 'sdist' command from within a python automated script without using subprocess?
I'm going to show a few alternatives to run the Babel Python code, without creating a new subprocess, from higher to lower level.
This is kind of a hack, taken from the answers linked above:
from setuptools.dist import Distribution from babel.messages.frontend import extract_messages dist = Distribution({'name': 'my-project', 'version': '1.0.0'}) # etc. dist.script_name = 'setup.py' cmd = extract_messages(dist) cmd.ensure_finalized() cmd.run() # TODO: error handling
pylabel script actually does something like this:
from babel.messages.frontend import main sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0]) sys.exit(main())
But you can avoid sending the commands over the sys.argv and actually call the CommandInterface python code from babel.
This is my favorite way to call it:
from babel.messages.frontend import CommandLineInterface CommandLineInterface().run(['pybabel','extract','-F','babel.cfg','-k','lazy_gettext','-o','messages.pot','sample_project']) CommandLineInterface().run(['pybabel','init','-i','messages.pot','-d','translations','-l','en']) CommandLineInterface().run(['pybabel','compile','-d','translations']) CommandLineInterface().run(['pybabel','update','-d','translations'])
That's the closest you can get to the low level code, unless you want to start copy/pasting and customizing the python code. Again, this is a 100% python solution, and it doesn't call a new process.
Good luck
