general(TYPE_TOTAL),- Read upRead up
- Exclude checks
This cop checks the indentation of the first element in an array literal where the opening bracket and the first element are on separate lines. The other elements' indentations are handled by the AlignArray cop.
By default, array literals that are arguments in a method call with parentheses, and where the opening square bracket of the array is on the same line as the opening parenthesis of the method call, shall have their first element indented one step (two spaces) more than the position inside the opening parenthesis.
Other array literals shall have their first element indented one step more than the start of the line where the opening square bracket is.
This default style is called 'specialinsideparentheses'. Alternative styles are 'consistent' and 'align_brackets'. Here are examples:
Example: EnforcedStyle: specialinsideparentheses (default)
# The `special_inside_parentheses` style enforces that the first
# element in an array literal where the opening bracket and first
# element are on seprate lines is indented one step (two spaces) more
# than the position inside the opening parenthesis.

This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.
The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.
