Generate Deps automatically.

[GHuserE]

Body

I write some code in Python on my other account. How do I generate automatically all dependencies that code uses? I have a lot of packages installed because I need to experiment. Maybe some code scanner and knowledge base?

Guidelines

Hey there @GHuserE

On Python, you can use the fallowing:

pip3 freeze > requirements.txt

This will list all installed packages into a file, including the precise version number. However, if you install a lot of other packages for other things, then this list may contain unnecessary elements. So, you should make sure that you use a virtual environment for development. Maybe consider doing your experiments in a seperate environment.

Here is how you setup an environment:

python3 -m venv location
source location/bin/activate

Then, running pip install <pck> will install the package in a clean environment and you can avoid pip freeze being polluted.

If this helps you, consider marking it as the answer. Thanks!

Hello @GHuserE

1. pip freeze: This is a built-in tool that can generate a list of installed packages and their versions. You can run pip freeze > requirements.txt in your terminal to create a requirements.txt file containing all installed packages and versions.

2. pipreqs: This is a third-party tool that automatically generates requirements.txt files based on the imports in your Python files. You can install it via pip (pip install pipreqs) and then run pipreqs /path/to/your/project to generate a requirements.txt file for your project.

3. Poetry/PIPENV: If you're using Poetry or Pipenv for managing your project dependencies, they also provide commands to generate and manage requirements.txt files or equivalent. For example, with Poetry, you can use poetry export -f requirements.txt > requirements.txt.

4. Pycharm/Visual Studio Code: If you're using an IDE like PyCharm or Visual Studio Code, they often have built-in features or extensions that can help you manage dependencies and generate requirements files.

5. Dependency Scanner APIs: Some services provide dependency scanning APIs, which can analyze your codebase and generate a list of dependencies. These may require integration with your version control system or code repository. Examples include Snyk, WhiteSource, and GitHub's dependency graph.

Good Luck!

@SYNAX07 Option 3 is on steroids 😆 Seriously though, thank you for sharing that one!
