QUANTUM is a modular and templated C language standard library extension / replacement aiming to make cross-platform development easier.

It provides portable and high performance modules to solve common problems and (re-)implementation of various (broken) standard library functions with modern object-oriented design and sane interfaces.

C99 or later is required.

There’s no documentation in traditional sense, but the source code is commented and organized fairly well: check it out and see what’s there.

A brief summary of included modules:

• core: fundamental definitions and language extensions.
• integer: integral types, their bit-precise characteristics, absolute value computation, SSE-accelerated (de-)serialization, support for 128-bit integer types, which are provided by Clang & GCC.
• bitops: bit-level manipulation of integral variables.
• bswap: reverse the order of bytes in integral variables.
• float: floating-point types and their characteristics.
• flint: floating-point integer definitions.
• memory: opaque memory buffer and generic memory pool.
• buffer: binary byte buffer functions.
• character: ASCII character classification and manipulation.
• string: templates for character string buffer manipulation, find & replace, transformation, implicit (null-terminated) strings.
• fs: common file system routines.
• io: common input / output routines.
• net: common network constants, types, macros, and host <-> network byte order conversion functions.
• Lots of other little modules: time, size, pointer, null, boolean, object, array, flexible, etc.

QUANTUM has been used to great success in development of Ultraviolet and Jsong.

QUANTUM is subject to the principle of uncertainty: it’s very experimental and its API may change at any moment without notice.

What kind of crazy idiot would use it?

Well... You maybe?
