Can zippos solve these 2 issues

[sdementen]

I have two issues with shiv
linkedin/shiv#209
linkedin/shiv#208
Does zipapps support these functionalities?

Allow shebang with %ENVIRONMENT VARIABLES% in it

1. As we known, both shiv and zipapps support the usage like python3 app.pyz, you don't really need shebang.

Slow run when large pyz file

1. One change of zipapps to shiv is to not unzip unless necessary

   1. The decompression behavior is only for the dynamic modules requirements (.pyd/.so, which written by C such as the scipy lib)
      1. Other requirements will not need to be decompressed because of the built-in zipimport feature.

2. To reduce decompression time, you can remove -c arg so it only be a archive zip file without compression

   1. But its file size will increase

[ClericPy]

To reduce decompression time, my often ways:

1. Use the layer mode on Serverless environment
2. Use the venv which has installed all the requirements.txt
3. Dump venv with zipapps
   1. python3 -m zipapps -r requirements.txt -o venv.pyz
   2. python3 -m zipapps -a your_code.py -m your_code.main -o app.pyz
   3. Run
      1. python3 venv.pyz app.pyz
   4. Then only upload the new app.pyz but keep the venv.pyz unchanged.

Separation of code and dependencies is a more feasible way, such as python3 -m venv venv, or pip install xxx -t ./requirements with export PYTHONPATH=./requirements

Thank you for your answers!
Within the lines, I understand zipapps core use case is easing the deployment on serverless environment. The use case for which I use shiv is for deployment of desktop applications on Windows machines.

zipapps and shiv has the same purpose, Serverless is only an example to tell the Separation of code and dependencies

My windows distribution choice is nuitka with pip install xxx -t app.dist and --nofollow-imports, or zipapps with delay install mode.

I have clarifier the use case for the shebang in the original issue

I am using the shebang to specify the specific version of the intepreter to be used (3.8, 3.9, ...) knowing that the user's laptop that will run the pyz have the different versions installed as "%USERPROFILE%\AppData\Local\Programs\Python\PythonNN".
Hence I would need the shebang line to accept the environment variable USERPROFILE.
