No, GError::message is designed to be displayed on screen, error
targeted to developers shall be displayed in the terminal (probably
using g_error, or assertions). The domain and code shall be used
whenever run-time handling of the error shall be made. 

I'm implementing a parser and want it to report line and column of parse
errors (not where the g_set_error was in the .c file) and already know
that GError is not extensible.

What is the standard way of reporting additional error information in

OK, I did this:

Made a factory class for my class:

TextgenTemplate *
   (TextgenTemplateParser *parser, ..., GError **error);

TextgenLocation *
   (TextgenTemplateParser *parser);

And also added get_error_location to TextgenTemplate itself:

   (TextgenTemplate *tpl, ..., GError **error);

TextgenLocation *
   (TextgenTemplate *tpl);

Is it an OK way to report error locations?
