Comfort, n. 
A consolation; something relieving suffering or worry.
"We still have the spare tire? That's a comfort at least."
Cxxomfort is a small, header-only library that backports to C++03 or C++11 some of the nifty C++11 and later goodies, including some proposals still in the works. I wrote it to facilitate my working with the evolving C++ standard as I was getting back into the language. It is intended to reduce the amount and stress of code rewrite while at the same time assisting in backwards and forwards portability.
Current version: 0.72 (2018-08)
Installation and Configuration
Quick and dirty:
Install the Fossil software then run:
fossil clone http://ryan.gulix.cl/fossil.cgi/cxxomfort cxxomfort.fossil fossil open cxxomfort.fossil
After that's done, you can in general just add the resulting directory path to compiler
#include paths; then write some code.
Using this library is as simple as writing C++ code. Include the cxxomfort header in your code:
#include <cxxomfort/cxxomfort.hpp> // or #include <cxxomfort/base.hpp> if you only plan to use the basic features
…and start using the various features that are made available, including but not limited in C++03 mode to
static_assert, iterator helpers and metaprogramming helpers, and
alignof where available, and in C++11 mode improvements to functional and tuple.
If you are interested in usage examples an amount of examples is available in the cxxomfort-examples Github repository (notabug mirror).
You can include only
cxxomfort/base.hpp in library code if you only need the base subset of cxxomfort features, without TR1-related utilities or any other sort of advanced features. Features for more information.
There are also some extra features that are included and activated explicitly, such as scoped enumeration emulation and a handful of proposals that haven't been verified yet into later Standards, such as
optional. See Features/Extras for more information.

- IndependentFeatures specific to cxxomfort, such as extra algorithms, foreach loops, local function emulation, fixed_vector, etc...
- Extra features such as implementation of experimental's optional, simple ranges, etc...
- Transparent Headers

The purpose of this library is to ease writing natural-feeling, forwards-compatible code once. As such, some design decisions are made that might conflict with conflict with certain pedantic "coding styles". For a quick, uncomprehensive check read Rationale.
The library does not aim to be perfect - that way lies madness, suffering, and suffering leads to anger, and anger leads to overused lines from movies. Instead, it aims to be "good enough" for the backports to be usable as far back as possible Standards-wise.
