warnFlagNames :: WarningFlag -> NonEmpty String Source #

Return the names of a WarningFlag

One flag may have several names because of US/UK spelling. The first one is the "preferred one" that will be displayed in warning messages.

warningGroups :: [(String, [WarningFlag])] Source #

Warning groups.

As all warnings are in the Weverything set, it is ignored when displaying to the user which group a warning is in.

warningHierarchies :: [[String]] Source #

Warning group hierarchies, where there is an explicit inclusion relation.

Each inner list is a hierarchy of warning groups, ordered from smallest to largest, where each group is a superset of the one before it.

Separating this from `warningGroups` allows for multiple hierarchies with no inherent relation to be defined.

The special-case Weverything group is not included.

smallestWarningGroups :: WarningFlag -> [String] Source #

Find the smallest group in every hierarchy which a warning belongs to, excluding Weverything.

standardWarnings :: [WarningFlag] Source #

Warnings enabled unless specified otherwise

minusWOpts :: [WarningFlag] Source #

Things you get with -W

minusWallOpts :: [WarningFlag] Source #

Things you get with -Wall

minusWeverythingOpts :: [WarningFlag] Source #

Things you get with -Weverything, i.e. *all* known warnings flags

minusWcompatOpts :: [WarningFlag] Source #

Things you get with -Wcompat.

This is intended to group together warnings that will be enabled by default at some point in the future, so that library authors eager to make their code future compatible to fix issues before they even generate warnings.

unusedBindsFlags :: [WarningFlag] Source #

Things you get with -Wunused-binds
