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.

◆ 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.

Reimplemented from clang::tidy::ClangTidyCheck.
