## clang-tidy - readability-identifier-naming

# readability-identifier-naming

Checks for identifiers naming style mismatch.

This check will try to enforce coding guidelines on the identifiers naming. It supports one of the following casing types and tries to convert from one to another if a mismatch is detected

Casing types include:

> - `lower_case`

> - `UPPER_CASE`

> - `camelBack`

> - `CamelCase`

> - `camel_Snake_Back`

> - `Camel_Snake_Case`

> - `aNy_CasE`

> - `Leading_upper_snake_case`

It also supports a fixed prefix and suffix that will be prepended or appended to the identifiers, regardless of the casing.

Many configuration options are available, in order to be able to create different rules for different kinds of identifiers. In general, the rules are falling back to a more generic rule if the specific case is not configured.

The naming of virtual methods is reported where they occur in the base class, but not where they are overridden, as it can’t be fixed locally there. This also applies for pseudo-override patterns like CRTP.

`Leading_upper_snake_case` is a naming convention where the first word is capitalized followed by lower case word(s) separated by underscore(s) ‘_’. Examples include: Cap_snake_case, Cobra_case, Foo_bar_baz, and Master_copy_8gb.

Hungarian notation can be customized using different HungarianPrefix settings. The options and their corresponding values are:

> - `Off` - the default setting

> - `On` - example: `int iVariable`

> - `LowerCase` - example: `int i_Variable`

> - `CamelCase` - example: `int IVariable`

AbstractClassCase

  When defined, the check will ensure abstract class names conform to the selected casing.

AbstractClassPrefix

  When defined, the check will ensure abstract class names will add the prefixed with the given value (regardless of casing).

AbstractClassIgnoredRegexp

  Identifier naming checks won’t be enforced for abstract class names matching this regular expression.

AbstractClassSuffix

  When defined, the check will ensure abstract class names will add the suffix with the given value (regardless of casing).

AbstractClassHungarianPrefix

  When enabled, the check ensures that the declared identifier will have a Hungarian notation prefix based on the declared type.

For example using values of:

> - AbstractClassCase of `lower_case`

> - AbstractClassPrefix of `pre_`

> - AbstractClassSuffix of `_post`

> - AbstractClassHungarianPrefix of `On`

Identifies and/or transforms abstract class names as follows:

Before:

    class ABSTRACT_CLASS {
    public:
      ABSTRACT_CLASS();
    };

After:

    class pre_abstract_class_post {
    public:
      pre_abstract_class_post();
    };

AggressiveDependentMemberLookup

  When set to true the check will look in dependent base classes for dependent member references that need changing. This can lead to errors with template specializations so the default value is false.

For example using values of:

> - ClassMemberCase of `lower_case`

Before:

    template <typename T>
    struct Base {
      T BadNamedMember;
    };

    template <typename T>
    struct Derived : Base<T> {
      void reset() {
        this->BadNamedMember = 0;
      }
    };

After if AggressiveDependentMemberLookup is false:

    template <typename T>
    struct Base {
      T bad_named_member;
    };

    template <typename T>
    struct Derived : Base<T> {
      void reset() {
        this->BadNamedMember = 0;
      }
    };

After if AggressiveDependentMemberLookup is true:

    template <typename T>
    struct Base {
      T bad_named_member;
    };

    template <typename T>
    struct Derived : Base<T> {
      void reset() {
        this->bad_named_member = 0;
      }
    };

CheckAnonFieldInParent

  When set to true, fields in anonymous records (i.e. anonymous unions and structs) will be treated as names in the enclosing scope rather than public members of the anonymous record for the purpose of name checking.

For example:

    class Foo {
    private:
      union {
        int iv_;
        float fv_;
      };
    };

If `CheckAnonFieldInParent` is false, you may get warnings that `iv_` and `fv_` are not coherent to public member names, because `iv_` and `fv_` are public members of the anonymous union. When `CheckAnonFieldInParent` is true, `iv_` and `fv_` will be treated as private data members of `Foo` for the purpose of name checking and thus no warnings will be emitted.

## The default mapping table of Hungarian Notation

In Hungarian notation, a variable name starts with a group of lower-case letters which are mnemonics for the type or purpose of that variable, followed by whatever name the programmer has chosen; this last part is sometimes distinguished as the given name. The first character of the given name can be capitalized to separate it from the type indicators (see also CamelCase). Otherwise the case of this character denotes scope.

The following table is the default mapping table of Hungarian Notation which maps Decl to its prefix string. You can also have your own style in config file.

Primitive Type |  |  |  | Microsoft Type |
--- | --- | --- | --- | --- | ---
Type | Prefix | Type | Prefix | Type | Prefix
int8_t | i8 | signed int | si | BOOL | b
int16_t | i16 | signed short | ss | BOOLEAN | b
int32_t | i32 | signed short int | ssi | BYTE | by
int64_t | i64 | signed long long int | slli | CHAR | c

## Options for Hungarian Notation

- `HungarianNotation.General.TreatStructAsClass`

- `HungarianNotation.DerivedType.Array`

- `HungarianNotation.DerivedType.Pointer`

- `HungarianNotation.DerivedType.FunctionPointer`

- `HungarianNotation.CString.CharPointer`

- `HungarianNotation.UserDefinedType.*`

HungarianNotation.General.TreatStructAsClass

  When defined, the check will treat naming of struct as a class. The default value is false.

HungarianNotation.DerivedType.Array

  When defined, the check will ensure variable name will add the prefix with the given string. The default prefix is a.

HungarianNotation.DerivedType.Pointer

  When defined, the check will ensure variable name will add the prefix with the given string. The default prefix is p.

HungarianNotation.DerivedType.FunctionPointer

  When defined, the check will ensure variable name will add the prefix with the given string. The default prefix is fn.

Before:

    // Array
    int DataArray[2] = {0};

    // Pointer
    void *DataBuffer = NULL;

    // FunctionPointer
    typedef void (*FUNC_PTR)();
    FUNC_PTR FuncPtr = NULL;

After:

    // Array
    int aDataArray[2] = {0};

    // Pointer
    void *pDataBuffer = NULL;

    // FunctionPointer
    typedef void (*FUNC_PTR)();
    FUNC_PTR fnFuncPtr = NULL;

HungarianNotation.CString.CharPointer

  When defined, the check will ensure variable name will add the prefix with the given string. The default prefix is sz.

HungarianNotation.CString.CharArray

  When defined, the check will ensure variable name will add the prefix with the given string. The default prefix is sz.

HungarianNotation.CString.WideCharPointer

  When defined, the check will ensure variable name will add the prefix with the given string. The default prefix is wsz.

HungarianNotation.CString.WideCharArray

  When defined, the check will ensure variable name will add the prefix with the given string. The default prefix is wsz.

Before:

    // CharPointer
    const char *NamePtr = "Name";

    // CharArray
    const char NameArray[] = "Name";

    // WideCharPointer
    const wchar_t *WideNamePtr = L"Name";

    // WideCharArray
    const wchar_t WideNameArray[] = L"Name";

After:

    // CharPointer
    const char *szNamePtr = "Name";

    // CharArray
    const char szNameArray[] = "Name";

    // WideCharPointer
    const wchar_t *wszWideNamePtr = L"Name";

    // WideCharArray
    const wchar_t wszWideNameArray[] = L"Name";

HungarianNotation.PrimitiveType.*

  When defined, the check will ensure variable name of involved primitive types will add the prefix with the given string. The default prefixes are defined in the default mapping table.

HungarianNotation.UserDefinedType.*

  When defined, the check will ensure variable name of involved primitive types will add the prefix with the given string. The default prefixes are defined in the default mapping table.

Before:

    int8_t   ValueI8      = 0;
    int16_t  ValueI16     = 0;
    int32_t  ValueI32     = 0;

    double   ValueDouble  = 0.0;
    ULONG    ValueUlong   = 0;
    DWORD    ValueDword   = 0;

After:
