template module when dest is a directory

If you use the template module and the dest parameter specifies a
directory, the module creates a file in the directory with the same name
as the value of the src parameter. However, if you then change the source
contents, and run ansible-playbook with --check --diff, it says that
there's a change but doesn't show the diff.

https://docs.ansible.com/ansible/template_module.html doesn't say that you
can specify a directory as the value of the dest parameter. Should that work?

If it should work to specify a directory, should 'diff' work as well?

I can create a bug report, but I wasn't sure what the intended/expected
behavior was.

That seems to be a bug.

Can you open a bug report with a minimal reproducer and the required context-information ? If it is a bug, we need to improve our integration tests to catch this one (before fixing ;-)).

Thanks !

Just to double-check: You think you should be able to specify a file as
the src parameter and a directory as the dest parameter (even though the
module docs don't say this), and that therefore diff should work? That
seems sensible to me, I just wanted to confirm before opening a bug about
something that isn't supposed to work. :^)

Yes, that ought to work.
