*
* @section overview_sec Overview
* Cppcheck is a simple tool for static analysis of C/C++ code.
2009-07-13 13:35:33 +02:00
*
* When you write a checker you have access to:
2015-08-16 21:57:07 +02:00
* - %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
2015-08-16 21:57:07 +02:00
* - 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++.
2009-07-18 09:11:02 +02:00
*
* @section detailed_overview_sec Detailed overview
* This happens when you execute cppcheck from the command line:
2009-07-18 09:11:02 +02:00
* -# 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.
