Logging from within helper functions

[emile.co...@gmail.com]

Is it possible to do logging (INFO, WARN, etc..) from within helper functions? I'm trying to do something like this:

static bool filesMatch(const std::string& path1, const std::string& path2)

{

    INFO("While comparing files '" << path1 << "' and '" << path2 << "'");

   

    // etc...

    if (line1 != line2)

    {

        INFO("Mismatch at line " << lineNo << ":\n"

             << line1 << "\nvs\n" << line2);

    }

    // etc...

}

and in my test case:

CHECK( filesMatch(path1, path2) );

But I don't see any logging messages when  the CHECK fails.

I figured it out. I simply need to FAIL from within my helper function and the logging messages will appear.

Yes. The logging macros are only valid for the current scope
