Usage

Creating a Python Environment

This library uses a very simple syntax to run Python scripts. To create a Python environment, simply run PyEnv::at(PathBuf).

use py_env::PyEnv;

let env = PyEnv::at("./py_test");

Running Arbitrary Code

use py_env::PyEnv;

PyEnv::at("./py_test")
    .execute("print('hello world')")
    .expect("Failed to execute code");

Installing Python Dependencies

The following code installs numpy into the ./py_test directory's site-packages and uses it in executed code.

use py_env::PyEnv;

PyEnv::at("./py_test")
    .install("numpy")
    .expect("Failed to install numpy")
    .execute("a = numpy.arange(15).reshape(3, 5); print(a.shape)")
    .expect("Failed to execute code");

Making Environments Impersistent

The following code deletes the python environment off of the disk once it's done running.

use py_env::PyEnv;

PyEnv::at("./py_test")
    .persistent(false)
    .install("numpy").expect("Failed to install numpy");

This was made as a code bounty, and as such is not a maintained project, but PRs are always welcome and will be reviewed when I see them.
