FR: uv init option to specify alternative filename to hello.py

[nbbaier]

When using uv init (or uv init --app), I find it kind of strange that entrypoint file generated is named hello.py and not main.py. Right, as far as I can tell, now the only solution is to manually change the filename.

It would be great to have an option to specify the entrypoint's filename, something like uv init --entrypoint main.py, or change the default to main.py instead of hello.py

My initial reaction is that adding an argument for this feels unnecessary. It’s almost as much work to provide the argument as it is to rename the file. I’m gonna defer to @zanieb on this one though.

Fair point. I think my preference here would actually be making uv init generate main.py over hello.py. Should have made that my request! For now, I've implemented this manually in my .zshrc with:

uvi() {
    uv init "$@"
    mv hello.py main.py
}

#7670 is similar but not the same, about picking more commonly preferred defaults

I think we could call it main.py instead — though having a function main in a file main and also having a __main__ file in some cases could be confusing. I'm not attached to the default name of hello.py though. It was mostly intended to be an example file that matched the other init kinds which have a hello command and function.
