Hi,

https://clang.llvm.org/docs/UsersManual.html

I don't find the official documentation of -x of clang. Where is the
complete list of languages supported by -x? Thanks.

I'm not aware of any documentation specifically for `-x`. You could check the implementation to get an idea:

Indeed, as it is not exposed for the end-users it is not on the UsersManual page.

You can find documentation for it here: https://clang.llvm.org/docs/ClangCommandLineReference.html taken from the help text I think.

But it still doesn’t have the list of supported languages, so reading the source code seems the only way.
