mkWarningCategory :: FastString -> WarningCategory Source #

defaultWarningCategory :: WarningCategory Source #

The deprecations category is used for all DEPRECATED pragmas and for WARNING pragmas that do not specify a category.

validWarningCategory :: WarningCategory -> Bool Source #

Is this warning category allowed to appear in user-defined WARNING pragmas? It must either be the known category deprecations, or be a custom category that begins with x- and contains only valid characters (letters, numbers, apostrophes and dashes).

fromWarningCategory :: WarningCategory -> InWarningCategory Source #

data WarningCategorySet Source #

A finite or infinite set of warning categories.

Unlike WarningFlag, there are (in principle) infinitely many warning categories, so we cannot necessarily enumerate all of them. However the set is constructed by adding or removing categories one at a time, so we can represent it as either a finite set of categories, or a cofinite set (where we store the complement).

emptyWarningCategorySet :: WarningCategorySet Source #

The empty set of warning categories.

completeWarningCategorySet :: WarningCategorySet Source #

The set consisting of all possible warning categories.

nullWarningCategorySet :: WarningCategorySet -> Bool Source #

Is this set empty?

elemWarningCategorySet :: WarningCategory -> WarningCategorySet -> Bool Source #

Does this warning category belong to the set?

insertWarningCategorySet :: WarningCategory -> WarningCategorySet -> WarningCategorySet Source #

Insert an element into a warning category set.

deleteWarningCategorySet :: WarningCategory -> WarningCategorySet -> WarningCategorySet Source #

Delete an element from a warning category set.
