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 inclde:

 - ``lower_case``,
 - ``UPPER_CASE``,
 - ``camelBack``,
 - ``CamelCase``,
 - ``camel_Snake_Back``,
 - ``Camel_Snake_Case``,
 - ``aNy_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.
