depzip 0.8

A small library for zipping Python application dependencies

The depzip library can be used for zipping dependencies of Python applications.

This library uses the sys.modules dictionary to discover dependencies and the ctypes.util.dllist function to discover DLLs loaded by dependencies.

Installation

This library can be installed using pip:

python -m pip install depzip

Usage

Here is a Python script showing how to use depzip to copy the dependencies of a Python application using matplotlib, numpy, and PySide6 into a file called bundle.zip:

import depzip

depzip.bundle(
    applications=[
        "app",
        "pyside6-uic",
    ],
    modules=[
        "app",
        "PySide6.QtUiTools",
    ],
    includes=[
        "Lib\\site-packages\\matplotlib\\mpl-data",
        "Lib\\site-packages\\numpy.libs",
        "Lib\\site-packages\\pyside6-uic",
        "Lib\\site-packages\\PySide6\\plugins\\platforms\\qwindows.dll",
        "Lib\\site-packages\\PySide6\\plugins\\styles\\qmodernwindowsstyle.dll",
        "Lib\\site-packages\\PySide6\\uic.exe",
    ],
    excludes=[
        "python.exe",
        "pythonw.exe",
    ],
    output="bundle.zip",
)

The source code of this script can be found in examples/bundle.py.

The provided executable file run.exe can be used to run a Python application. It initializes Python and runs a module with the same name as the executable file. For example, to run a Python module named app, the executable file run.exe should be renamed to app.exe.

The source code of the executable file run.exe can be found in examples/run.c.

The applications parameter is a list of application names that is used to automatically copy run.exe to executable files with names in this list.

The modules parameter is a list of Python modules used by the applications. These modules are copied to the output file along with all their dependencies.

The includes parameter is a list of additional files and directories to be copied to the output file.

The excludes parameter is a list of files that should not be copied to the output file.

The output parameter is the name of the output file.
