Pip picking up a custom install cmdclass

Pip picking up a custom install cmdclass

If you have a custom installation command class that you want pip to pick up when installing a Python package, you need to specify the custom command class in your package's setup.py file. The custom command class should inherit from a relevant setuptools command class, and it can be used to customize the installation process.

Here are the steps to make pip recognize and use your custom cmdclass:

  1. Create Your Custom Command Class:

    Create a Python class that defines your custom installation logic. This class should inherit from a relevant setuptools command class. For example, if you want to customize the install command, you can inherit from setuptools.command.install.install.

    from setuptools.command.install import install class MyCustomInstall(install): def run(self): # Your custom installation logic here print("Custom installation logic") install.run(self)

  2. Modify setup.py:

    In your package's setup.py file, import your custom command class and include it in the cmdclass dictionary of the setup() function. Here's an example:

    from setuptools import setup from mypackage import __version__ # Import your package version from mypackage.custom_install import MyCustomInstall # Import your custom command class setup( name='mypackage', version=__version__, # Other package information... # Specify your custom command class in cmdclass cmdclass={'install': MyCustomInstall}, )

    Ensure that you replace 'mypackage' with your actual package name and 'mypackage.custom_install' with the correct import path for your custom command class.

  3. Install Your Package with pip:

    Now, when you install your package using pip, it will recognize and use your custom cmdclass. Run the following command from the directory containing your setup.py file:

    pip install .

    The . specifies the current directory, where pip will find the setup.py file.

  4. Customize Installation Logic:

    In your custom command class (MyCustomInstall in the example), you can implement your custom installation logic as needed. This may include copying files, modifying configurations, or performing other tasks specific to your package.

With these steps, pip will use your custom installation logic when installing your package, allowing you to customize the installation process as desired.

    • Description: This query is about extending Pip's installation process with custom commands to perform additional tasks before or after installation.
    • Code:
      from setuptools import setup from setuptools.command.install import install class CustomInstall(install): def run(self): # Custom pre-installation logic print("Performing custom pre-installation tasks") install.run(self) # Custom post-installation logic print("Performing custom post-installation tasks") setup( # Other setup parameters cmdclass={'install': CustomInstall} )

  3. Implementing custom installer using Pip cmdclass?

    • Description: This query pertains to implementing a custom installer using Pip's cmdclass attribute, often required for specialized installation procedures.
    • Code:
      from setuptools import setup from setuptools.command.install import install class CustomInstall(install): def run(self): # Custom installer logic print("Custom installer logic executed") install.run(self) setup( # Other setup parameters cmdclass={'install': CustomInstall} )
