Detailed Description

Checks for identifiers naming style mismatch.

This check will try to enforce coding guidelines on the identifiers naming. It supports lower_case, UPPER_CASE, camelBack and CamelCase casing and tries to convert from one to another if a mismatch is detected.

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 kind of identifier. In general, the rules are falling back to a more generic rule if the specific case is not configured.

◆ check()

overridevirtual

◆ checkMacro()

void clang::tidy::readability::IdentifierNamingCheck::checkMacro ( SourceManager &  sourceMgr,
const Token &  MacroNameTok,
const MacroInfo *  MI

Check Macros for style violations.

◆ expandMacro()

void clang::tidy::readability::IdentifierNamingCheck::expandMacro ( const Token &  MacroNameTok,
const MacroInfo *  MI 
)

Add a usage of a macro if it already has a violation.

◆ onEndOfTranslationUnit()

void clang::tidy::readability::IdentifierNamingCheck::onEndOfTranslationUnit ( )
override

◆ registerMatchers()

void clang::tidy::readability::IdentifierNamingCheck::registerMatchers ( ast_matchers::MatchFinder *  Finder)
overridevirtual

Override this to register AST matchers with Finder.

This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.

You can register as many matchers as necessary with Finder. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.

If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.

◆ registerPPCallbacks()

void clang::tidy::readability::IdentifierNamingCheck::registerPPCallbacks ( CompilerInstance &  Compiler)
overridevirtual

Override this to register PPCallbacks with Compiler.

This should be used for clang-tidy checks that analyze preprocessor- dependent properties, e.g. the order of include directives.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 236 of file IdentifierNamingCheck.cpp.

◆ storeOptions()

void clang::tidy::readability::IdentifierNamingCheck::storeOptions ( ClangTidyOptions::OptionMap Options)
overridevirtual

Should store all options supported by this check with their current values or default values for options that haven't been overridden.

The check should use Options.store() to store each option it supports whether it has the default value or it has been overridden.
