LitV [ VERY VERY ALPHA ]

A uv inspired tool made with rust. A python helper if you will.

Where do I get it?

• Linux Build: https://nightly.link/daveberrys/LitV/workflows/nightly/main/litv-Linux.zip
• Windows Build: https://nightly.link/daveberrys/LitV/workflows/nightly/main/litv-Windows.zip
• macOS (arm): https://nightly.link/daveberrys/LitV/workflows/nightly/main/litv-macOS-arm.zip
• macOS (intel): https://nightly.link/daveberrys/LitV/workflows/nightly/main/litv-macOS-Intel.zip

How do I use it?

Since this is a CLI tool, you run it from the terminal. Here are the arguments:

Click to see the arguments (it's a long one...)

• litv init
  • Initialize a new project in the folder you're in
  • Extras:
    • litv run <project_name>
      • Initializes a new project in a new directory with the given name.
      • project_name is optional.
• litv run
  • Checks if you have .venv directory.'
    • If not, initializes a new virtual environment by doing litv venv.
  • Run src/main.py through the virtual environment
  • Extras:
    • litv run <file>
      • To run a specific file through the virtual environment.
    • litv run -- <args>
      • Passthrough arguments to the python script.
    • litv run <file> <args>
      • To run a specific file through the virtual environment with passthrough arguments.
• litv add
  • Checks:
    • If you have .venv directory.
      • If not, initializes a new virtual environment by doing litv venv.
    • If pyproject.toml exists.
      • If not, it will prompt the user that pyproject.toml does not exist and the user must create one by doing litv init or creating themselves.
  • If no other argument is given, downloads every single package from pyproject.toml.
  • Extras:
    • litv add <package>
      • <package> is the name of the package to add to pyproject.toml.
    • litv add <package> -i
      • -i is a optional flag that will install the package and then place the package you installed to pyproject.toml.
    • litv add <package> -b
      • -b is a optional flag that will use pip to install the package and then place the package you installed to pyproject.toml.
• litv remove <package>
  • <package> is the name of the package to remove from pyproject.toml.

  • Extras:
    • litv remove <package> -b

    • litv venv --<python_version>
      • <python_version> is the version of Python to use for the virtual environment. (eg: litv venv --3.13)

Is this LLM Assisted?

Yes. I needed help with most of the code. I'm being fully transparent about this.
