Using cProfile on application with entry point

Question

I know cProfile can be used like this

python -m cProfile script.py

But suppose I have a packaged application (pip-installable) with an entry_point defined in setup.py, such that I can call the application from the terminal, without explicitly using any .py file. How can I use cProfile in that case?

I found the answer in this thread:

python -m cProfile $(which application)

`$(which application)` is simply your entry point script (with path). – Marcin Orlowski Jun 07 '19 at 11:43
@MarcinOrlowski Yes, I didn't know that's what I had to call with cProfile. – foxpal Jun 07 '19 at 12:06
You don't. If you know the path you just put it as you mentioned in your question. What `$(...)` does is invoking `which` that returns full path of `application` (if on PATH). – Marcin Orlowski Jun 07 '19 at 12:14

What if someone is using click for CLI ? It seems not to be working for me.

Update: Actually cProfile requires main, and adding standard

if __name__=="__main__":
    cli()

to mymodule/cli.py program, solved the issue.
