uniform-fileio: Uniform file handling operations

[ data-text-uniform, gpl, library ] [ Propose Tags ]

Uniform operations for handling files and file path names independent from the representation.

Additionally, functions to read and write files for specific typed content (marked by extension).

Readme for uniform-fileio-0.1.2

[back to package description]

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.
