Synopsis

Documentation

taglib :: TagLib a -> IO aSource

Run a TagLib block. Save and free any files left open when the block is finished, and free all strings produced by taglib.

openFile :: FilePath -> TagLib FileId Source

Open a file and return a corresponding FileId. Internally, this grabs the Tag and AudioProperties pointers to the TagLib_File.

packStringTag :: SetStringTag -> FileId -> Text -> TagLib ()Source

Given a IO action which expects a Tag pointer and CString, lifts it into an TagLib action, expecting Text.

packIntTag :: SetIntTag -> FileId -> Int -> TagLib ()Source

Given a IO action which expects a Tag pointer and CInt, lifts it into an TagLib action, expecting a Int.

unpackStringTag :: GetStringTag -> FileId -> TagLib Text Source

Given a IO action which expects a Tag pointer and results in a CString, lifts it into a TagLib action, resulting in Text.

unpackIntTag :: GetIntTag -> FileId -> TagLib Int Source

Given a IO action which expects a Tag pointer and results in a CInt, lifts it into a TagLib action, resulting in Int.

unpackIntAP :: GetIntAP -> FileId -> TagLib Int Source

Given a IO action which expects a AudioProperties pointer and results in a CInt, lifts it into a TagLib action, resulting in Int.
