Description
This module provides extra helper functions complementing Language.Haskell.TH.Lib
Synopsis
- integralE :: Integral a => a -> ExpQ
- simpleValD :: Name -> TypeQ -> ExpQ -> Q [Dec]
- maybeD :: (a -> Q [Dec]) -> Maybe a -> Q [Dec]
- pprQ :: (Functor m, Quasi m, Ppr a) => Q a -> m Doc
- reportWarning :: String -> Q ()
- reportError :: String -> Q ()
Extra template functions
Extra functions to generate haskell templates.
simpleValD :: Name -> TypeQ -> ExpQ -> Q [Dec] Source #
Generate declaration template from name, type and expression.
Pretty printing for Q monad
Pretty printing for haskell templates.
pprQ :: (Functor m, Quasi m, Ppr a) => Q a -> m Doc Source #
Helper function for pretty printing Q Monad.
Functions to print message or errors when compile time
Functions to display or to raise compile messages from codes which generating haskell templates.
Only messages directly generated by Q monad report actions
are handled by ghc loggers.
-- Handled by ghc logger qReport False "Foo"
-- Not handled by ghc logger runIO . runQ $ qReport False "Foo"
reportWarning :: String -> Q () Source #
Print compile warnings from TH code.
reportError :: String -> Q () Source #
Print compile errors from TH code.
