|
*
|
|
* @section overview_sec Overview
|
|
* Cppcheck is a simple tool for static analysis of C/C++ code.
|
|
*
|
|
* The method used is to first tokenize the source code and then analyse the token list.
|
|
* In the token list, the tokens are stored in plain text.
|
|
*
|
|
* The checks are written in C++. The checks are addons that can be easily added/removed.
|
|
*
|
|
* @section writing_checks_sec Writing a check
|
|
* Below is a simple example of a check that detect division with zero:
|
|
* @code
|
|
void CheckOther::checkZeroDivision()
|
|
{
|
|
// Iterate through all tokens in the token list
|
|
for (const Token *tok = _tokenizer->tokens(); tok; tok = tok->next())
|
|
{
|
|
if (Token::Match(tok, "/ 0"))
|
|
reportError(tok, Severity::error, "zerodiv", "Division by zero");
|
|
}
|
|
}
|
|
@endcode
|
|
*
|
|
* The function Token::Match is often used in the checks. Through it
|
|
* you can match tokens against patterns.
|
|
*
|
|
*
|
|
* @section checkclass_sec Creating a new check class from scratch
|
|
* %Check classes inherit from the Check class. The Check class specifies the interface that you must use.
|
|
* To integrate a check class into cppcheck all you need to do is:
|
|
* - Add your source file(s) so they are compiled into the executable.
|
|
* - Create an instance of the class (the Check::Check() constructor registers the class as an addon that Cppcheck then can use).
|
|
*
|
|
*
|
|
* @section embedding_sec Embedding Cppcheck
|
|
* Cppcheck is designed to be easily embeddable into other programs.
|
|
*
|
|
* The "src/main.cpp" and "src/cppcheckexecutor.*" files illustrate how cppcheck
|
|
* can be embedded into an application.
|
|
*
|
|
*
|
|
* @section detailed_overview_sec Detailed overview
|
|
* This happens when you execute cppcheck from the command line:
|
|
* -# CppCheckExecutor::check this function executes the Cppcheck
|
|
* -# CppCheck::parseFromArgs parse command line arguments
|
|
* - The Settings class is used to maintain settings
|
|
* - Use FileLister and command line arguments to get files to check
|
|
* -# ThreadExecutor create more instances of CppCheck if needed
|
|
* -# CppCheck::check is called for each file. It checks a single file
|
|
* -# Preprocess the file (through Preprocessor)
|
|
* - Comments are removed
|
|
* - Macros are expanded
|
|
* -# Tokenize the file (see Tokenizer)
|
|
* -# Run the runChecks of all check classes.
|
|
* -# Simplify the tokenlist (Tokenizer::simplifyTokenList)
|
|
* -# Run the runSimplifiedChecks of all check classes
|
|
*
|
|
* When errors are found, they are reported back to the CppCheckExecutor through the ErrorLogger interface
