Automatically build a virtualenv environment whenever requirements.txt changes

About

Autodeps automatically builds a virtualenv environment based on requirements.txt. This build happens on demand when autodeps is imported.

Usage

First, add autodeps to your project. Either using a submodule or by copying it.

Next, add something similar to the following in your adddeps.py or at the top of your main file:

root = os.path.dirname(os.path.abspath(__file__))
autodeps = os.path.join(root, '../autodeps/autodeps.py')
execfile(autodeps, {'__file__': autodeps,
                    '__name__': 'activate_root',
                    'root': root})

Then create an autodeps.json in your root folder like:

{
  "requirements": ["{root}/requirements.txt"],
  "venv-latest": "{root}/.venv_latest"
}

Finally, populate requirements.txt with your python dependencies.

Configuration Options

• requirements: A list of paths to requirements.txt files containing deps to install.
• venv-dir-search: A list of paths to search and create store virtualenvs in.
• venv-dir-required-gigabytes: How much free space is required for a path in venv-dir-search to be used.
• archived-venv-dir: Path to a directory where tar files of virtualenvs are stored and shared between users. You may want to put this on a shared filesystem.
• venv-latest: Path where a symlink to the latest virtual environment should be placed.
• submodule-update: Optional path to a directory to run git submodule update in.
• virtualenv: Path to virtualenv binary to use. Defaults to bundled virtualenv-bootstrap.
