Synopsis

data Replacement = Replacement {

- replOriginal :: String
- replReplacement :: String
}
data Change
- = NoChange
- | Change [Replacement] [AnnotatedImports]

Documentation

replace :: (Data a, MonadIO m) => Context -> a -> TransformT (WriterT Change m) a Source #

Specializes replaceImpl to each of the AST types that retrie supports.

data Replacement Source #

Records a replacement made. In cases where we cannot use ghc-exactprint to print the resulting AST (e.g. CPP modules), we fall back on splicing strings. Can also be used by external tools (search, linters, etc).
