Detailed Description

Finds symbol which have confusable identifiers, i.e.

identifiers that look the same visually but have a different Unicode representation. If symbols are confusable but don't live in conflicting namespaces, they are not reported.

◆ registerMatchers()

void clang::tidy::misc::ConfusableIdentifierCheck::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.

This will only be executed if the function isLanguageVersionSupported returns true.

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.
