|
|
* @section overview_sec Overview
|
|
* Cppcheck is a simple tool for static analysis of C/C++ code.
|
|
*
|
|
* When you write a checker you have access to:
|
|
* - %Token list - the tokenized code
|
|
* - Syntax tree - Syntax tree of each expression
|
|
* - %SymbolDatabase - Information about all types/variables/functions/etc
|
|
* in the current translation unit
|
|
* - Library - Configuration of functions/types
|
|
* - Value flow analysis - Data flow analysis that determine possible values for each token
|
|
*
|
|
* Use --debug-normal on the command line to see debug output for the token list
|
|
* and the syntax tree. If both --debug-normal and --verbose is used, the symbol
|
|
* database is also written.
|
|
*
|
|
* The checks are written in C++.
|
|
*
|
|
* @section detailed_overview_sec Detailed overview
|
|
* This happens when you execute cppcheck from the command line:
|
|
* -# CppCheckExecutor::check this function executes the Cppcheck
|
|
* -# CmdLineParser::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::simplifyTokenList2)
|
|
* -# Run the runSimplifiedChecks of all check classes
|
|
*
|
|
* When errors are found, they are reported back to the CppCheckExecutor through the ErrorLogger interface.
