Fmlib_std Standard Data TypesFmlib_pretty Pretty PrintingFmlib_parse ParsingAll libraries of Fmlib are prefixed by Fmlib_ to avoid nameclashes with any other used libraries.
All components of Fmlib work independently of any input/output methods i.e. they can be used in any environment.
The printers do not actually print. They generate a lazy stream of characters which can be output on any medium.
The parsers do not actually read from input. They work in push mode. You can choose your input method and you push the characters into the parser.
The library is functional in the sense that it avoids mutation or uses mutation only locally to improve performance. Exception handling is avoided as well. The module Fmlib_std.Result can be used to achieve the same effect as exception handling.
