Hello,
I would like to expand CommonOptionsParser class with a new argument to specify an output file (something like -o “generated.cpp”). What would be the best way to do that?

As this sounds like something that is not common to pretty much all tools,
I'd say - put it into the actual tool you're writing?

Hi Manuel,
Haha, yes, It’s exactly what I’m intending to do. The problem is that CommonOptionsParser calls cl::ParseCommandLineOptions(argc, argv) and I was trying to figure on how to inject custom arguments inside it.

Take a look at the class comment in
llvm/tools/clang/include/clang/Tooling/CommonOptionsParser.h
If something doesn’t work as described there (or if we can make it clearer) let me know 
Cheers,

Ah, figured it out, just placing this code:
static llvm:
:optstd::string OutputPath(
“o”, llvm::desc(“Output file”), llvm::Optional);
before calling:
CommonOptionsParser parser( argc, argv );
on my tool does some static black magic that automagically adds the option to the application.
Thanks,
Victor
