grepLines :: IsRegex re ByteString => re -> FilePath -> IO [Line] Source #
returns a Line for each line in the file enumerating all of the
matches for that line.
type GrepScript re s t = [(re, LineNo -> Matches s -> Maybe t)] Source #
a GrepScript lists RE-action associations, with the first RE to match a line selecting the action to be executed on each line in the file
grepScript :: IsRegex re s => GrepScript re s t -> [s] -> [t] Source #
given a list of lines, apply the GrepScript to each line of the file
specifies whether to return the linss matched or missed
