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;        →

Abbreviations

OK: Listed in Wikipedia or universally known (i, n, id, url)
Capitalize as word: StartRpc() not StartRPC()
Don't delete letters: customer not cstmr

Check Process

Identify the entity type (class, function, variable, etc.)
Apply the corresponding naming rule
Check for consistency with surrounding code
Flag any Hungarian notation or other outdated styles
