cppcheck的规则集 [英] Rulesets for cppcheck
问题描述
Cppcheck允许您创建自己的规则文件，但我不知道cppcheck的功能暴露了多少。
Cppcheck allows you to create your own rules files, but I don't know how much of cppcheck's functionality is exposed.
推荐答案
所有MISRA / JSF规则和指令作为cppcheck规则，大多数只是直接的限制某些C语言特性和结构，或者是风格相关的（一些注意：空格前/后./->单行，使用联合提供访问内存的不同方法，在char之前存在unsigned / signed等）。
You won't be able to implement all MISRA/JSF rules and directives as cppcheck rules, mostly only the straightforward ones restricting certain C language features and constructions or that are style-related (some that come to mind: spaces before/after ./->, # of arguments on a single line, use of unions to provide different methods of accessing memory, presence of unsigned/signed before char, etc).
用户伊拉·巴克斯特几乎把它钉在一个注释另一个问题触摸cppcheck：不是一切都可以表示/简化为模式。依赖于自定义规则的模式，很难处理和检测更高级别的问题，例如与类型（例如sizeof（））相关的类型;解析和收集用作类型表示的令牌（typedef，枚举），继承（例如类，包括派生类，用作虚拟和非虚拟） 和范围。那些需要硬编码到cppcheck（你可以总是fork cppcheck ...）
User Ira Baxter pretty much nailed it in a comment on another question touching cppcheck: not everything can be represented/simplified as a pattern. Relying on patterns for custom rules makes it difficult to handle and detect higher level issues, related for example to types (e.g. sizeof() on types; you would have to parse and collect tokens (typedefs, enums) used as a type representation), inheritance (e.g. classes, incl. derived ones, used both as virtual and non-virtual), and scope. Those need to be hard-coded into cppcheck (you could always fork cppcheck...)
在任何情况下，你是否接触过MISRA（或JSF）规则？这是项目的要求吗？如果没有，您可以获取一份MISRA指南（您已经拥有JSF指南），并检查您可以使用PCRE模式实现的指南。如果这是一个要求，我建议您投资一个商业产品，检查MISRA / JSF指南并使用这两种工具。
In any case, have you touched MISRA (or JSF) rules? Is this a requirement for a project? If not, you could grab a copy of the MISRA guidelines (you already have the JSF ones) and check the ones you can implement using PCRE patterns. If it is a requirement, I suggest you "invest" in a commercial product that does check for MISRA/JSF guidelines and use both tools.
最后一点：不需要所有的MISRA / JSF规则，并且许多工具只留下一小部分。
A final note: you don't need all the MISRA/JSF rules, and many tools leave a small percentage of those out.
