With haskell's turtle library, how to extract filename from FilePath? -

-

when using takefilename type error:

:t v print v :t takefilename takefilename v  v :: filepath  filepath "/media/miguel/backup/backups"  takefilename :: filepath -> filepath couldn't match type ‘turtle.filepath’ ‘string’ expected type: ihaskellsysio.filepath   actual type: turtle.filepath in first argument of ‘takefilename’, namely ‘v’ in expression: takefilename v

is because turtle's filepath different prelude's filepath ?

turtle still uses system-filepath has customized "filepath" type can find here. many other haskell libraries use filepath library defines filepath synonym string (type filepath = string). case here ihaskell.

so yes both filepath types mismatch. note can convert turtle.filepath string using show (because type has show instance). can convert text using fp turtle.format module.

system-filepath deprecated. there issue this. please read: https://github.com/gabriel439/haskell-turtle-library/issues/54

hope helps.
