# 🐍 pvx

Python version &amp; venv management (maybe more ...)

## 🤪 What can pvx do ?

![pvx-help](./asset/pvx-help.png)

## 📦 Install

Use pipx (recommend)

```bash
pipx install pvx
```

Or pip

```bash
pip install pvx
```

Don't forget [`python-build`](https://github.com/pyenv/pyenv/tree/master/plugins/python-build) and it [dependencies](https://github.com/pyenv/pyenv/wiki#suggested-build-environment).

```bash
git clone https://github.com/pyenv/pyenv.git ~/.pyenv
```
[pyenv](https://github.com/pyenv/pyenv) is usually installed at `~/.pyenv` by default. If it is installed silently, then everything is ready, otherwise add `PVX_PY_BUILD_PATH=/your/pyenv/path/plugins/python-build` to `env` (`plugins/python-build` is usually fixed).

## 🔧 Usage

- List  version number that you can download.

    ```bash
    pvx py archive 

    # If you want to filter it, do this
    pvx py archive 3.10
    ```

- Install.

    ```bash
    pvx py insetall 3.10.4
    ```

- List versions of installed.

    ```bash
    pvx py list
    ```

- Remove the specified version of Python.

    ```bash
    pvx py remove 3.10.4
    ```

- Create a virtual environment (pvx use [Python Venv](https://docs.python.org/3/tutorial/venv.html) and compatible with its parameters)

    ```bash
    # All default (current python and default venv prompt)
    pvx venv new

    # Specify the version (which install by pvx)
    pvx venv new 3.10.4

    # Use existing Python
    pvx venv new ~/.pyenv/versions/3.10.4/bin/python

    # Use venv's parameters, such as specifying prompt
    pvx venv new 3.10.4 --prompt venv_prompt_name

    # Use current python and venv's parameters
    pvx venv new --prompt venv_prompt_name
    ```

- List all virtual environments

    ```bash
    # You'll see a table , highlight the activate one.
    pvx venv list
    ```

- Activate virtual environment with `PROMPT`

    ```bash
    # use `pvx venv list` to show prompt
    pvx venv activate prompt_name
    ```

- Remove virtual environment with `PROMPT`

    ```bash
    # use `pvx venv list` to show prompt
    pvx venv remove prompt_name
    ```

## Optional environment variable

- `PVX_ROOT_PATH`: pvx home path. `Default: ~/.pvx`
- `PVX_PYTHON_INSTALLATION_PATH`: The installation folder for Python. `Default: ~/${PVX_ROOT_PATH}/versions`
- `PVX_VENV_IN_PROJECT`: Whether the virtual environment is installed in the project. `Default: true`
- `PVX_VENV_DIR_NAME_IN_PROJECT`: The folder name of virtual environment. `Default: .venv`
- `PVX_VENV_EXTERNAL_PATH`: If `PVX_VENV_IN_PROJECT` is false, the virtual environment is installed externally rather than in the project. `Default: ~/${PVX_ROOT_PATH}/venv`
- `PVX_PY_BUILD_HOME`: pyenv plugin python-build home path. `Default: ~/.pyenv/plugins/python-build`

## 🌟 Extend functionality

If you want to extend commands, be familiar with the following points.

1. The folder where the `pvx.py` file resides is the `root`.
2. `root/commands` is the folder where the `.py` command scripts are stored.
3. If `filenamed` is true, use the file name command, otherwise use the argument to `@click.command`.
        - The `.py` files are named `pvx_{group}_{command}.py`.For example: `pvx_py_install.py`, which means we can call it with `pvx py install`.
4. `.py` file must have a method called `cli` and decorated with `@click.command` .

## 👻 Thanks

pvx was my experiment after studying `pyenv`, `poetry` `rich` and `click`. Thank them for their efforts, fun 😁 ~

      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,

      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
