Documentation
data SystemPath Source #
A data type encapsulating different kinds of relative or absolute paths.
Constructors
| Path FilePath | A path that will just be passed through |
| InHomeDir FilePath | A OS specific path relative to the home directory of a user. |
| InB9UserDir FilePath | A path relative to the |
| InTempDir FilePath | A path relative to the systems temporary directory. |
Instances
resolve :: MonadIO m => SystemPath -> m FilePath Source #
Convert a SystemPath to a FilePath.
ensureDir :: MonadIO m => FilePath -> m () Source #
Create all missing parent directories of a file path.
Note that the file path is assumed to be of a regular file, and
takeDirectory is applied before creating the directory.
getDirectoryFiles :: MonadIO m => FilePath -> m [FilePath] Source #
Get all files from dir that is get ONLY files not directories
consult :: (MonadIO m, Read a) => FilePath -> m a Source #
Read a value of a type that is an instance of Read from a file.
This function throws a ConsultException when the read the file failed.
