Installing Poetry and running the virtual environment

ℹ️ Poetry Documentation

Install Poetry

For Linux, macOS, Windows (WSL):

curl -sSL https://install.python-poetry.org | python3 -

For Windows (Powershell):

(Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -

On macOS and Windows, the installation script will prompt you to add the Poetry executable folder to the PATH variable. Do this by running the following command (don't forget to change {USERNAME} to your username):

macOS

export PATH="/Users/{USERNAME}/.local/bin:$PATH"

Windows

$Env:Path += ";C:\Users\{USERNAME}\AppData\Roaming\Python\Scripts"; setx PATH "$Env:Path"

Check installation:

poetry --version

Installing bash completions (optional):

poetry completions bash >> ~/.bash_completion

Start virtual environment

🔖 Setting up the Poetry environment for PyCharm

Creating a virtual environment:

poetry env use python3.10

Installing dependencies:

poetry install

Launching the shell and activating the virtual environment (from the project folder):

poetry shell

Checking virtual environment activation:

poetry env list

Install pre-commit hooks

In order for pre-commit checks to be performed with each commit, you must:

• Install pre-commit
• Install pre-commit hooks

Install pre-commit

The pre-commit module has already been added to the requirements and should be installed automatically with the virtual environment.

You can check the presence of pre-commit with the command (with the virtual environment activated):

pre-commit --version
# >> pre-commit 2.21.0

If this does not happen, then you need to install pre-commit according to the official instructions:

• install via brew package manager: brew install pre-commit
• installation via poetry: poetry add pre-commit
• pip install: pip install pre-commit

Install hooks

Installing hooks:

pre-commit install --all

In the future, when executing the git commit command, the checks listed in the .pre-commit-config.yaml file will be performed.

If it is not clear which error is preventing the commit from being executed, you can run the hooks manually with the command:

pre-commit run --all-files

Example Usage

To use the decorators provided by decorators-cryptography, follow the examples below.

from decorators_cryptography import encrypt, decrypt

@encrypt(key="encryption_key")
def sensitive_function(arg1, arg2):
    # Your function implementation
    pass

@decrypt(key="decryption_key")
def sensitive_function(arg1, arg2):
    # Your function implementation
    pass
