Shared coding conventions allow teams to collaborate effectively. This rule allows to check that all class names match a provided regular expression.

The default regular expression is based on PEP-8 standard. It allows "CapWords" convention and "snake_case" in lowercase. The "snake_case" convention is accepted by PEP-8 when the class is primarily used as a callable (ex: decorator, context manager, etc...). However the "CapWords" convention is recommended in every case.

== Noncompliant Code Example

With default provided regular expression ``++^_?([A-Z_][a-zA-Z0-9]\*|[a-z_][a-z0-9_]\*)$++``:

----
class myClass:  # Noncompliant
   ...

class my_CONTEXT_manager:  # Noncompliant
    def __enter__(self):
        pass
    def __exit__(self, type, value, traceback):
        pass
----

== Compliant Solution

----
class MyClass:
   ...

class my_context_manager:
    def __enter__(self):
        pass
    def __exit__(self, type, value, traceback):
        pass
