additional_packaging.py file

To extend the build process, you can create a additional_packaging.py file in the same file level where you have your globalConfig file.

This file should have either of the below two functions:

• the cleanup_output_files function, which accepts output_path (str), add-on name (str) as its arguments.
• the additional_packaging function, which accepts add-on name (str) as its only argument.

First the cleanup_output_files function would be called from ucc-gen build process and then additional_packaging function.

See the following example for proper usage:

• Build custom UI after ucc-gen finishes all its necessary steps.
• Use a workaround for a ucc-gen feature that has not been implemented.

Example

Below is an example of additional_packaging.py containing both the implementations of functions.

from os.path import sep, exists, dirname, realpath, join
from os import remove, system, _exit, WEXITSTATUS

def additional_packaging(ta_name=None):
    """

    """
    if exists(
        join(dirname(realpath(__file__)), "build-ui.sh")
    ):
        system("chmod +x ./build-ui.sh")
        return_code = system("./build-ui.sh")
        if return_code != 0:
            _exit(WEXITSTATUS(return_code))

def cleanup_output_files(output_path: str, ta_name: str) -> None:
    """
