class Streamable a where |
Type class for string manipulation over files.
| | Methods | | | Instances | |
|
|
renameWith |
:: (FilePath -> FilePath) | function to rename with
| -> FilePath | file to rename
| -> IO () | | Use a renaming function to generate a new name for a file, then
rename it.
|
|
|
modifyWith |
:: Streamable a | | => (FilePath -> FilePath -> IO ()) | file manipulation action
| -> (a -> a) | transformation function
| -> FilePath | | -> IO () | | Modify a file in place using the given function. The new content
is written to a temporary file. Once this is complete, the file
manipulation action is called. Its arguments are the names of the
original and temporary files.
Example:
modifyInPlace = modifyWith (flip rename)
|
|
|
modifyWithBackup |
:: Streamable a | | => (FilePath -> FilePath) | chooses new name for original file
| -> (a -> a) | transformation function
| -> FilePath | name of file to modify
| -> IO () | | Modify a file in place using the given function. The original
copy of the file is saved under a new name. This is performed by
writing to a temporary file; renaming the original file to its new
name; then renaming the temporary file to the original name.
Example:
-- save original file with a ".bak" extension
modifyWithBackup (<.> "bak")
|
|
|
modifyInPlace |
:: Streamable a | | => (a -> a) | transformation function
| -> FilePath | name of file to modify
| -> IO () | | Modify a file in place using the given function. This is
performed by writing to a temporary file, then renaming it on top of
the existing file when done.
