Support for scalable large records
Usage
{-# OPTIONS_GHC -fplugin=Data.Record.Plugin #-} {-# ANN type B largeRecord #-} data B a = B {a :: a, b :: String} deriving stock (Show, Eq, Ord)
See LargeRecordOptions
for the list of all possible annotations.
Usage with record-dot-preprocessor
There are two important points. First, the order of plugins matters —
record-dot-preprocessor
has to be listed before this plugin (and
correspondingly will be applied after this plugin):
{-# OPTIONS_GHC -fplugin=RecordDotPreprocessor -fplugin=Data.Record.Plugin #-}
Second, you will want at least version 0.2.14.
