Qak

by Marsh Ray <marsh@extendedsubet.com>

Some C++ code I find useful and wanted to release under a permissive license.
Pronounce 'kak'. All of the good short names are taken or, if not, this project
is not yet deserving enough to take one of them.

I experiment with C++11, crypto, and interactve applications with OpenGL. Perhaps
a simple game or utility application will come of it someday, but in the meantime
some of the code is reusable and might be generally useful to others.

Qak is also an experiment with reducing compilation times and using smaller,
minimal-dependency headers. For example, a simple #include <vector> with libstdc++
drags in over 10000 non-blank non-comment lines of C++ code. (Gcc's precompiled header
support can help with compilation time considerably, but it still accumulates
large internal data structures that seem to reduce compile times.) Following the
80/20 rule, a qak::vector<> class that trades features and performance for
simplicity requires only a few hundred lines of code. I typically don't use
vector's allocator support anyway.

At the current time, the toolset used for development is:

	MS Visual Studio 2013 C++

Also had once been tested with:

	MS Visual Studio 2012 C++

	g++ 4.6.2
	libstdc++ 6.0.16
	cmake 2.8.0
	Linux 2.6.32-35 x86_64 AKA amd64 AKA x64
	Ubuntu 10.04 LTS _Lucid Lynx_ - Release amd64 (20100429)


Misc coding practices:

	C++ source files are named .cxx and .hxx
	External interface headers go in src/include/qak
	Implementation sources go in     src/libqak

	Unit test apps are named *__test

	4 space tabs
	Soft 120 column margin

	C++11 (aka C++0x) features are adopted as they become available in g++.

	Some ugly workarounds are provided for compilers that don't yet support various features.
	These will be removed as soon as they become available in the vendor's latest compiler version.

	Use //? or //?TODO to indicate places that are incomplete or may need review or revision.
	Use //? or //?OPT to indicate possible performance optimizations.




Headers from the standard library, annotated with the lines of dependency c++ headers
and the total LoC.

Include these freely and assume they are already needed and impose no additional cost:

	#include <cstdint> // 4 1309 std::uintN_t
	#include <cstddef> // 4 1261 std::nullptr_t
	#include <cstring> // 4 1331 std::mem[cmp|cpy|move|set]
	#include <cassert> // 1 36
	#include <type_traits> // 4 2260 std::aligned_storage, is_integral, enable_if
	#include <new> // 8 1766 placement new
	#include <utility> // 10 2999 std::swap

These are 'allowed' anywhere, but assume they have some cost.

	#include <ciso646> 1 29
	#include <cassert> 1 36
	#include <cerrno> 1 42
	#include <climits> 1 47

	#include <cmath> 6 3094
	#include <functional> 23 7416
	#include <limits> 4 2514

Avoid these, except perhaps confined to a single translation designed to
re-expose their functionality via its own smaller header.
