Filediff

The module exposing the functionality of this package

basic operations

diffFiles :: FilePath -> FilePath -> IO Filediff

O(mn). Compute the difference between the two files (more specifically, the minimal number of changes to make to transform the file residing at the location specified by the first parameter into the second). Throws an exception if either or both of the parameters point to a directory, not a file.

Files are allowed to not exist at either or both of the parameters.

diffDirectories :: FilePath -> FilePath -> IO Diff

Compute the difference between the two directories (more specifically, the minimal number of changes to make to transform the directory residing at the location specified by the first parameter into the second). Throws an exception if either or both of the parameters point to a file, not a directory.

applyToFile :: Filediff -> FilePath -> IO [Line]

O(n). Apply a diff to a directory or file

applyToDirectory :: Diff -> FilePath -> IO ()

True upon success; False upon failure
