could filename be shorter

[javaxiu]

after preprocessor does, FILE could looks like /Users/xxxx/workspace/foo/src/somefilename, but it was too long though, src/somefilename or even somefilename would be enough.

so i think is that possable to write pprocessor-loader.json file like this

"macros": [
    {
      "declaration" : "LOG_INFO(message)",
      "definition" : "console.log(message + ' (__FILE__:__LINE__)');",
      "REG": "/(src:?)(.*)/"
    },
]

thanks
