@hackage uniform-fileio0.1.3

Uniform methods to access data in files.

Goals:

• same functions with identical semantics independent of representation

• all functions are total (or become so using Maybe or Either)

• performance is NOT a goal - once the program logic is confirmed and tested, performance improvements can be achieved based on observations. The goal for "uniform" is reducing the complexity for the designer of a program - performance improvement come when the logic is correct.

Specifically:

• a file path can be given as Filepath (which is a string) or as a Path, which different types for directories and files and for absolute and relative path, to reduce confusing.

• functions to work on file path independent of representation

• functions to access file with either type of path representation

• operations are total; failures of file operations are signaled by ErrorT or Either returns.

Experimentally:

• TypedFile.hs tries to extend a type concept from the representation in memory to a representation on file (indicated by the file extension). It proposes a set of functions to read structured files into structured data - selected by the extensions.
