How to use single shiv zipapp/pyz for multiple python scripts

[sudarshanvm]

Suppose I have 3 files : requirements.txt, module1.py and module2.py
I need to bake a single shiv executable with all the dependencies specified inside requirements.txt and later I want to use the same shiv executable for running module1.py as well as module2.py

can we do something like:

• bake shiv using shiv requirements.txt -o shiv.pyz
• to run module1.py, export SHIV_ENTRY_POINT=module1:main and then ./shiv.pyz should run the module1 script
• to run module2.py, export SHIV_ENTRY_POINT=module2:main and then ./shiv.pyz should run the module2 script

does this work? do we have any alternative to do that?

Thanks, Sudarshan

Hi @sudarshanvm,

A pyz created with shiv should work exactly as you describe. In fact, internally at LinkedIn we sometimes package multiple CLIs that share a set of dependencies this way. Another option is to use the pyz as the shebang for a script, like so:

$ shiv httpx -o httpx.pyz --quiet
$ cat << EOF > tryme.py
> #!/usr/bin/env httpx.pyz
>
> import httpx
> url = "https://shiv.readthedocs.io"
> response = httpx.get(url)
> print(f"Got {response.status_code} from {url}!")
>
> EOF
$ chmod +x tryme.py
$ ./tryme.py
Got 200 from https://shiv.readthedocs.io!
