data Edits m re s Source #

an Edits script will, for each line in the file, either perform the action selected by the first RE in the list, or perform all of the actions on line, arranged as a pipeline


Select [(re, Edit m s)] 
Pipe [(re, Edit m s)] 

data Edit m s Source #

each Edit action specifies how the match should be processed


Template s 
Function Context (LineNo -> Match s -> Location -> Capture s -> m (Maybe s)) 
LineEdit (LineNo -> Matches s -> m (LineEdit s)) 

data LineEdit s Source #

a LineEdit is the most general action thar can be performed on a line and is the only means of deleting a line


ReplaceWith s 


Show s => Show (LineEdit s) Source # 


showsPrec :: Int -> LineEdit s -> ShowS #

show :: LineEdit s -> String #

showList :: [LineEdit s] -> ShowS #

applyEdits :: (IsRegex re s, Monad m, Functor m) => LineNo -> Edits m re s -> s -> m s Source #

apply an Edit script to a single line

applyEdit :: (IsRegex re s, Monad m, Functor m) => (s -> s) -> LineNo -> re -> Edit m s -> s -> m (Maybe s) Source #

apply a single edit action to a line, the function in the first argument being used to add a new line onto the end of the line where appropriate; the function returns Nothing if no edit is to be performed on the line, Just mempty to delete the line

applyLineEdit :: Monoid s => (s -> s) -> LineEdit s -> Maybe s Source #

apply a LineEdit to a line, using the function in the first argument to append a new line to the result; Nothing should be returned if no edit is to be performed, Just mempty to delete the line
