WARNING: This module represents the old version of the HLint API. It will be deleted in favour of Language.Haskell.HLint3 in the next major version.
This module provides a library interface to HLint, strongly modelled on the command line interface.

Documentation
hlint :: [String] -> IO [Suggestion] Source #
This function takes a list of command line arguments, and returns the given suggestions.
To see a list of arguments type hlint --help at the console.
This function writes to the stdout/stderr streams, unless --quiet is specified.
As an example:
do hints <- hlint ["src", "--ignore=Use map","--quiet"] when (length hints > 3) $ error "Too many hints!"
suggestionLocation :: Suggestion -> SrcLoc Source #
From a suggestion, extract the file location it refers to.
suggestionSeverity :: Suggestion -> Severity Source #
From a suggestion, determine how severe it is.
How severe an issue is.
