It is possible to use more than one '''#line''' keywords, but it seems having just one at the top for little script is enough to pinpoint position of the error easily. | It is possible to use more than one '''#line''' keywords, but it seems having just one at the top for little script is enough to pinpoint position of the error easily. | ||

- The main difference between preprocessFile and preprocessFileLineNumbers is that the latter adds #line keyword to the target file, which allows to log the __LINE__ error happened at and the __FILE__ error happened in.

The #line directive get's removed from the output.
So to add a custom #line directive before while using preprocessFileLineNumbers, you have to use a preprocessor macro like this:
#define DEBUG(sharp,name) sharp##line 0 name
and add this at the right place in your code
DEBUG(#,"your filename"); This way you can have custom filenames in error messages.
