#[C++ Core Guidelines](isocpp.github.io/CppCoreGuidelines)
|
|
|
|
>"Within C++ is a smaller, simpler, safer language struggling to get out."
|
|
>-- <cite>Bjarne Stroustrup</cite>
|
|
|
|
The C++ Core Guidelines are a collaborative effort led by Bjarne Stroustrup, much like the C++ language itself. They are the result of many
|
|
person-years of discussion and design across a number of organizations. Their design encourages general applicability and broad adoption but
|
|
they can be freely copied and modified to meet your organization's needs.
|
|
|
|
The aim of the guidelines is to help people to use modern C++ effectively. By "modern C++" we mean C++11 and C++14 (and soon C++17). In other
|
|
words, what would you like your code to look like in 5 years' time, given that you can start now? In 10 years' time?
|
|
|
|
The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management, and concurrency. Such
|
|
rules affect application architecture and library design. Following the rules will lead to code that is statically type safe, has no resource
|
|
leaks, and catches many more programming logic errors than is common in code today. And it will run fast - you can afford to do things right.
|
|
|
|
We are less concerned with low-level issues, such as naming conventions and indentation style. However, no topic that can help a programmer is
|
|
out of bounds.
|
|
|
|
Our initial set of rules emphasize safety (of various forms) and simplicity. They may very well be too strict. We expect to have to introduce
|
|
more exceptions to better accommodate real-world needs. We also need more rules.
|
|
|
|
You will find some of the rules contrary to your expectations or even contrary to your experience. If we haven't suggested you change your
|
|
coding style in any way, we have failed! Please try to verify or disprove rules! In particular, we'd really like to have some of our rules
|
|
backed up with measurements or better examples.
|
|
|
|
You will find some of the rules obvious or even trivial. Please remember that one purpose of a guideline is to help someone who is less
|
|
experienced or coming from a different background or language to get up to speed.
|
|
|
|
The rules are designed to be supported by an analysis tool. Violations of rules will be flagged with references (or links) to the relevant rule.
|
|
We do not expect you to memorize all the rules before trying to write code.
|
|
|
|
The rules are meant for gradual introduction into a code base. We plan to build tools for that and hope others will too.
|
|
|
|
Comments and suggestions for improvements are most welcome. We plan to modify and extend this document as our understanding improves and the
|
|
language and the set of available libraries improve.
