Lenses
extension :: Lens' FilePath FilePath Source
A Lens
for reading and writing to the extension
Note: This is not a legal Lens
, unless you are careful to ensure that generated
extension FilePath
components are either null or start with extSeparator
and do not contain any internal extSeparator
s.
>>>
extension .~ ".png" $ "path/name.txt"
"path/name.png"
filename :: Lens' FilePath FilePath Source
A Lens
for reading and writing to the full filename
Note: This is not a legal Lens
, unless you are careful to ensure that generated
filename FilePath
components are not null and do not contain any
elements of pathSeparators
s.
>>>
filename .~ "name.txt" $ "path/name.png"
"path/name.txt"
