Description
I found out, that a shell completion doesn't work on scripts with a dot in their name, mainly the scripts themselves (without an entry point linked) or entry points with a dot in their name (less common). The main problem is that the dot is copied into the name of the completion variable.
MWE:
Let's have a script /tmp/example.py
import click
@click.command()
def main():
pass
if __name__ == '__main__':
main()Completion on this script doesn't do anything using any of reasonable variable names:
_EXAMPLE_COMPLETE=bash_source python3 /tmp/example.py
_EXAMPLEPY_COMPLETE=bash_source python3 /tmp/example.py
_EXAMPLE_PY_COMPLETE=bash_source python3 /tmp/example.pyI found out, click requires the variable _EXAMPLE.PY_COMPLETE to be set, which is not possible (at least) in bash.
It would help if the dot was replaced by an underscore, the same way a dash is handled.
Environment:
- Python version: 3.9.9
- Click version: 8.0.3
