Comfort, n. [2]

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: 0.48 (2015-06)

Installation and Configuration

Quick and dirty:

fossil clone
fossil open cxxomfort

The basic installation procedure is as follows: download package or clone repo; extract package or copy repo to an adequate directory; add directory path to compiler #include paths; then write some code.

For specifics:


Using this library is as simple as writing C++ code. Include the cxxomfort header in your code:

#include <cxxomfort/cxxomfort.hpp>

…and start using the various features that are made available, including but not limited in C++03 mode to nullptr, static_assert, iterator helpers and metaprogramming helpers, and alignof where available.

You can include the header cxxomfort/base.hpp in library code where you want to have the benefit of the most basic features that do not require TR1 or other components to be made available; see 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.

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.
