Looking at Python packaging with pyproject.toml, I wonder whether it is possible to add a standalone executable (with #!/usr/bin/env python in the first line) to pyproject.toml, without going for a [project.scripts] entrypoint definition and the corresponding auto-generated wrapper. Do I understand right that pyproject.toml supports only the [project.scripts] entrypoint definitions as a way to define executables?
I don't have anything against the entrypoints. It makes the definition of Python executables platform-independent. But it's just a curious aspect of pyproject.toml.
Specifically, is it possible to have a project like this:
pyproject.toml
my_executable.py
my_packet/
__init__.py
my_module.py
Where my_executable.py has the +x permissions bits for execution and contains code like this:
#!/usr/bin/env python
from my_packet.my_module import func
def main():
return func()
if __name__ == '__main__':
main()
For completeness, the same in the entrypoint way:
pyproject.toml
my_packet/
__init__.py
my_module.py
my_executable.py
With pyproject.toml:
...
[project.scripts]
my-executable = "my_packet.my_executable:main"
Where my_executable.py is:
from my_packet.my_module import func
def main():
return func()
# may not have if __name__ at all
# or contain not application code
# like some tests
Then the executable gets generated during installation. And it looks like this:
#!/home/.../my_venv/bin/python
# -*- coding: utf-8 -*-
import re
import sys
from my_packet.my_executable import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
sys.exit(main())
