Considering panel for a gui: can I package as an exe?

Panel
6

Hi!

I’ve managed to resolve this on Linux. I created a wheel for my Panel App by using the following setup.py:

from setuptools import setup, find_packages

setup(
    name='MyApp',
    ...
    packages=find_packages(),
    install_requires=[
        'numpy>=1.22',
        ...
        ],
    extra_requires={'dev': ['twine>=4.0.2']},
    classifiers=[
        'Programming Language :: Python :: 3',
        ...
    ],
    scripts=['MyApp.sh',
             'myapp.py',
             ],
    python_requires='>=3.12',
)

Note: the key idea is to put MyApp.sh and myapp.py in the scripts section in order to have them available in your $PATH later.

Note that the MyApp.sh is a shell script that will launch the panel app. In my case, it looks like this:

#! /usr/bin/bash

panel serve --show $(dirname $0)/myapp.py

The $(dirname $0) will get the current path from the MyApp.sh script (wich is the same for myapp.py).

Then, I created the wheel file:

python setup.py bdist_wheel sdist

At this point, there will be a wheel file created in the dist directory. Now you can upload it to PyPi or use it for a local installation. To test, I created another environment (make sure to have all the packages dependencies installed) and installed the wheel:

pip install --force-reinstall myapp.whl

Note: I used the --force-reinstall to ensure that the modifications I made elsewhere would take effect upon installation.

With the wheel file installed within an appropriated environment, I could launch MyApp.sh from elsewhere on my computer.

I’m not sure, but this seems more like a makeshift solution than an adequate one for what it is intented for, but it works in my case.

Caveats: in this way, both MyApp.sh and myapp.py will be included in your $PATH, which is not ideal, since we just want MyApp.sh.
