Use this rule to control the number of spaces inside brackets (``[`` and
|
|
``]``).
|
|
|
|
.. rubric:: Options
|
|
|
|
* ``min-spaces-inside`` defines the minimal number of spaces required inside
|
|
brackets.
|
|
* ``max-spaces-inside`` defines the maximal number of spaces allowed inside
|
|
brackets.
|
|
* ``min-spaces-inside-empty`` defines the minimal number of spaces required
|
|
inside empty brackets.
|
|
* ``max-spaces-inside-empty`` defines the maximal number of spaces allowed
|
|
inside empty brackets.
