Package Information

Description:

/Warning:/ This version of the package is very experimental and the interface may change in later versions. I am seeking comments to improve it. This package is composed of two functions for formatted conversion between strings and typed values. Each is defined as a type-indexed function using a type class with multiple parameters and functional dependencies along with format descriptors. "Text.XFormat.Read" allows one to parse values from a formatted string. Its functionality is similar to the C @scanf@ function. Unlike @scanf@, however, the format descriptor is well-typed, ensuring that the output type is statically known. "Text.XFormat.Show" allows one to print values to a formatted string. Its functionality is similar to the C @printf@ function. Unlike @printf@, however, the format descriptor is well-typed, ensuring that the variable number arguments are statically known. These functions can be easily extended to support new formats and new types. Extension is simple: define a format descriptor and an instance of the appropriate class.
