Parser to extract data from a Vagrantfile into a data struct readable by python
Project description
pyvagrantfile
Parses a vagrant file into a python object for inspect. Mainly used to read and build Vagrant file in python. I built this to help me write a utility in python which can build projects and convert Vagrantfiles to packer files.
Supported Directives
Most vm.config directives,
Chef provisioner
Shell provisioner
VB provider
Installation
After it’s on the pip server, you should be able to install on the client by running
$ pip install pyvagrantfile
Deployment
When this is ready to be deployed, you can upload it to the pip server
$ cd $WORKSPACE/pyvagrantfile $ python setup.py sdist upload
Usage
Contributing
virtualenv
When doing development and testing, it’s good practice to use a virtualenv. A virtualenv is a sandboxed python environment which does not modify the system python installation You can install one as follows:
$ pip install virtualenv $ cd $WORKSPACE/pyvagrantfile $ virtualenv venv $ . ./venv/bin/activate (pyvagrantfile)$
Now that you have a working virtualenv, you can install the utility in development mode. Keep in mind that the ‘activate’ step, is valid only for a single session. If you close the terminal you’ll have to run venv/bin/activate again. You can now run pip, python, and pyvagrantfile while only referring to the local python environment created in $WORKSPACE/pyvagrantfile. You can see this by running:
(pyvagrantfile)$ which pip $WORKSPACE/pyvagrantfile/venv/bin/python (pyvagrantfile)$ which python
Development Mode
When testing this utility, you can install it and still edit the source files as follows:
$ cd $WORKSPACE/pyvagrantfile $ pip install --editable .
Roadmap
I intially tried to use pyPEG, but could not get a handle on it, so for now, we use a custom state parser. I want to move this to a PEG parser to make it easier to manage, but in the spirit of minimum viable product, it’s up and out.
This is currently way too specific. Needs to be rewritten to parse general ruby structures and extract details out of it, rather than looking for particular vagrant configurations.
Port parser from state parser to PEG parser.
