Language.Haskell.Exts.Extension

Contents

Description

This entire module should be replaced with Language.Haskell.Extension from cabal, but we must wait for a release of cabal that includes the XmlSyntax and RegularPatterns extensions.

Synopsis

Extensions

classifyExtension :: String -> ExtensionSource

A clever version of read that returns an UnknownExtension if the string is not recognised.

impliesExts :: [Extension] -> [Extension]Source

Certain extensions imply other extensions, and this function makes the implication explicit. This also handles deprecated extensions, which imply their replacements. The returned valued is the transitive closure of implied extensions.

Extension groups

glasgowExts :: [Extension]Source

The list of extensions enabled by GHC's portmanteau -fglasgow-exts flag.
