C++ Naming Convention Checker

Verify names follow Google C++ Style Guide conventions.

Naming Rules Quick Check

Entity	Convention	Pattern	Examples
Files	lowercase + `_` or `-`	`snake_case.cc`	`my_class.cc`, `http-parser.h`
Classes	PascalCase	`[A-Z][a-zA-Z0-9]*`	`MyClass`, `UrlParser`
Structs	PascalCase	`[A-Z][a-zA-Z0-9]*`	`Point`, `HttpRequest`
Type aliases	PascalCase	`[A-Z][a-zA-Z0-9]*`	`DataMap`, `StringList`
Enums	PascalCase	`[A-Z][a-zA-Z0-9]*`	`ErrorCode`, `State`
Enumerators	kPascalCase	`k[A-Z][a-zA-Z0-9]*`	`kOk`, `kNotFound`
Functions	PascalCase	`[A-Z][a-zA-Z0-9]*`	`ProcessData()`, `GetValue()`
Accessors	snake_case	`[a-z][a-z0-9_]*`	`count()`, `set_count()`
Variables	snake_case	`[a-z][a-z0-9_]*`	`table_name`, `num_items`
Class members	snake_case_	`[a-z][a-z0-9_]*_`	`value_`, `data_map_`
Struct members	snake_case	`[a-z][a-z0-9_]*`	`width`, `height`
Constants	kPascalCase	`k[A-Z][a-zA-Z0-9]*`	`kMaxSize`, `kPi`
Macros	UPPER_CASE	`[A-Z][A-Z0-9_]*`	`MY_MACRO`, `DEBUG_LOG`
Namespaces	snake_case	`[a-z][a-z0-9_]*`	`my_project`, `internal`
Template params	Varies	Type=`T`, value=`n`	`T`, `InputIterator`, `N`

Common Mistakes

❌ Wrong → ✅ Correct

// Classes
class myClass;        → class MyClass;
class HTTPParser;     → class HttpParser;  // Treat acronyms as words

// Variables
int TableName;        → int table_name;
int tablename;        → int table_name;    // Use underscores

// Class members
int value;            → int value_;        // Trailing underscore
int m_value;          → int value_;        // No Hungarian notation

// Functions
void process_data();  → void ProcessData();
void getValue();      → void GetValue();   // Or get_value() if accessor

// Constants
const int MAX_SIZE;   → const int kMaxSize;
const int maxSize;    → const int kMaxSize;

// Enumerators
enum { ERROR_OK };    → enum { kErrorOk };
enum { Ok };          → enum { kOk };

// Macros (must be UPPER_CASE with prefix)
#define DEBUG         → #define MYPROJECT_DEBUG
