virtualenv-project

The virtualenv-project resource handles the creation (and also the destruction) of Python virtual environments in a directory. This resource requires that virtualenv be already installed on the system. This resource will not activate virtual environments for you. That will need be done separately using source .<dest>/bin/activate where <dest> is the name of the dest directory.

Parameters:

• dest: (string, required) The path to the destination folder for the virtual environment. If cwd is specified then this value is a relative path to cwd.

• python: (string) The path to the python interpreter to use to create the virtualenv. This defaults to the global python3 version

• noVcsIgnore: (boolean) Don't create VCS ignore directive in the destination directory (default: false)

• systemSitePackages: (boolean) Give the virtual environment access to the system site-packages dir (default: false)

• symlinks: (boolean) Try to use symlinks rather than copies (default: true)

• cwd: (string) The cwd to create virtualenv from. This allows a relative path to be used for dest. Also, the directory automaticallyInstallRequirementsTxt will attempt to install from.

• automaticallyInstallRequirementsTxt: (boolean) If an requirements.txt is available in the cwd, automatically install it when a virtual env is first created.

Example usage:

[
  { "type": "homebrew" },
  { "type": "virtualenv" },
  {
    "type": "virtualenv-project",
    "dest": ".venv",
    "cwd": "~/Projects/example-project2",
    "automaticallyInstallRequirementsTxt": true
  }
]

In this example we install virtualenv (and homebrew which is a dependency) and then we initialize virtualenv in the project located at ~/Projects/example-project2. The virtual environment itself is located in the .venv folder and uses the global python3 version.

[
  { "type": "homebrew" },
  { "type": "virtualenv" },
  {
    "type": "git-repository",
    "directory": "~/Projects/example-project2",
    "repository": "git@github.com:daniel-dqsdatalabs/python-template.git"
  },
  {
    "type": "virtualenv-project",
    "dest": ".venv",
    "cwd": "~/Projects/example-project2",
    "automaticallyInstallRequirementsTxt": true,
    "dependsOn": ["git-repository"]
  }
]

In this example, we use the git-repository resource to first clone a python project from Github. We then use the virtualenv-project resources to setup Python in a virtual environment and install the dependencies listed in requirements.txt
