I'm doing this to avoid macro name conflicts, following https://google.github.io/styleguide/cppguide.html#Preprocessor_Macros: "If you do export a macro from a header, it must have a globally unique name. To achieve this, it must be named with a prefix consisting of your project's namespace name (but upper case)." Commands run: ``` sed -i 's/\(DCHECK\|CHECK\|FATAL\|MAKE_UNIQUE_NAME\|MAKE_UNIQUE_NAME_IMPL\|RAW_EXITING_STREAM\|RETURN_IF_ERROR\|RETURN_IF_ERROR_IMPL\|ASSIGN_OR_RETURN\|ASSIGN_OR_RETURN_IMPL\|DIAGNOSTIC_KIND\|RETURN_IF_STACK_LIMITED\)(/CARBON_\1(/g' $(git ls-files *.cpp *.h *.lpp *.ypp *.def ':!third_party') sed -i 's/#undef DIAGNOSTIC_KIND/#undef CARBON_DIAGNOSTIC_KIND/' toolchain/diagnostics/diagnostic_registry.def ``` Note this isn't *quite* everything, but it's intended to be a large pass at everything: ``` ╚╡git grep '#define ' *.cpp *.h *.lpp *.ypp *.def ':!third_party' | grep -v '#define CARBON' | grep -v _H_ explorer/syntax/lexer.lpp: #define YY_USER_ACTION \ explorer/syntax/lexer.lpp: #define SIMPLE_TOKEN(name) \ explorer/syntax/lexer.lpp: #define ARG_TOKEN(name, arg) \ explorer/syntax/parse_and_lex_context.h:#define YY_DECL \ migrate_cpp/cpp_refactoring/var_decl.cpp:#define ABSTRACT_TYPE(Class, Base) migrate_cpp/cpp_refactoring/var_decl.cpp:#define TYPE(Class, Base) \ ``` We may in particular want to do a pass to clean up #ifdef guards and make them be CARBON_ rooted.
