"""Pre-generation hook for the cli cookiecutter template.
|
|
|
|
Validates that ``project_name`` is a valid Python identifier so the
|
|
generated package dir + imports (``from <project_name>.X import Y``) do
|
|
not raise ``SyntaxError``. Hyphens, dots, spaces and leading digits are
|
|
rejected with a hint to use an underscore-separated name instead.
|
|
|
|
See issue #262: default ``my-cli`` used to render as
|
|
``from my-cli.core import app`` which is a ``SyntaxError`` (``-`` is not
|
|
allowed in a Python identifier).
