Installation

To install pydaffodil, follow these steps:

1. Install Python: Make sure you have Python 3.6+ installed. You can download it from python.org.

2. Install PyDaffodil:

   You can install pydaffodil from PyPI using pip:

   pip install pydaffodil

3. Verify Installation:

   After installation, you can verify it by importing pydaffodil in your Python script or in the Python interpreter:

   from pydaffodil import Daffodil

   If no errors are raised, the installation was successful.

Usage

Here's an example of how to use pydaffodil for deployment:

from pydaffodil import Daffodil

cli = Daffodil(remote_user="root", remote_host="123.221.11.243", remote_path="/root/prod/bccs")

steps = [
    {"step": "Build the project", "command": lambda: cli.run_command("npm run build")},
    {"step": "Stop backend process on remote server", "command": lambda: cli.ssh_command("sudo forever stop 1")},
    {"step": "Transfer files to remote server", "command": lambda: cli.transfer_files("build")},
    {"step": "Restart backend process on remote server", "command": lambda: cli.ssh_command("sudo forever restartall")}
]

cli.deploy(steps)

Note: require admin privileges to run the script.

How to Republish to PyPI

To republish this project to PyPI after making changes, follow these steps:

1. Update the Version Number

In order to upload a new version to PyPI, you must increment the version number in the setup.py file. For example, if the current version is 1.0.0, change it to 1.0.1:

# setup.py
setup(
    name="pydaffodil",
    version="1.0.1",  # Increment the version number here
    # Other metadata...
)

2. Build the Package

Run the following command to build both the source distribution (.tar.gz) and the wheel (.whl) files:

python -m build

This will generate the package files in the dist/ folder.

3. Upload the Package to PyPI

Once your package is built, you can use twine to upload it to PyPI. Run the following command to upload the new version:

twine upload dist/*

You'll be prompted to enter your PyPI credentials. Make sure to have them ready.

4. Test Your New Release

After uploading, you can verify that the new version has been successfully published by installing it using pip:

pip install --upgrade pydaffodil

This will install the latest version of the package.

5. Re-uploading to TestPyPI (Optional)

If you'd like to test the release before publishing it to the official PyPI, you can upload to TestPyPI instead:

twine upload --repository-url https://test.pypi.org/legacy/ dist/*

Then install it from TestPyPI to verify:

pip install --index-url https://test.pypi.org/simple/ pydaffodil

This ensures that everything is working correctly before pushing the package to the main PyPI repository.
