Comment at: clang-tools-extra/clang-tidy/readability/IdentifierNamingCheck.cpp:441-456
+static IdentifierNamingCheck::HungarianPrefixOption
+parseHungarianPrefix(std::string OptionVal) {
+  for (auto &C : OptionVal)
+    C = toupper(C);
+
+  if (std::string::npos != OptionVal.find("LOWER_CASE"))
+    return IdentifierNamingCheck::HungarianPrefixOption::HPO_LowerCase;
----------------
This isn't really needed if you have the mapping defined, `Options.get` works with enums, just look at how CaseType is parsed and stored. If you want to map multiple strings to a single enum constant that can also work by putting both strings in the mapping.
This method also validates inputs and will print out an error if a user supplies a value that can't be converted.


================
Comment at: clang-tools-extra/clang-tidy/readability/IdentifierNamingCheck.cpp:460
 getNamingStyles(const ClangTidyCheck::OptionsView &Options) {
+  static IdentifierNamingCheck::HungarianNotationOption HNOption;
+  HNOption.clearAll();
----------------
This function can be called multiple times per translation unit when looking through header files if `GetConfigPerFile` is enabled. Making this static will mean that each file thats read could potentially alter other files style configuration.
Maybe a smarter way about this is rather than this function returning a vector of naming styles, it returns a struct which contains the Hungarian options and a vector of the styles. Doing this would probably also mean you don't need to store a reference to this in the `NamingStyle`.
