google-global-names-in-headers¶

Flag global namespace pollution in header files. Right now it only triggers on using declarations and directives.

The check supports these options:

• HeaderFileExtensions: a comma-separated list of filename extensions of header files (the filename extensions should not contain ”.” prefix). “h” by default. For extension-less header files, using an empty string or leaving an empty string between ”,” if there are other filename extensions.

The relevant style guide section is https://google.github.io/styleguide/cppguide.html#Namespaces.
