[GRASS-dev] G_program_name to every message

[Jachym Cepicky]

Hallo,

I think it would be nice, if G_message, G_warning and G_fatal_error
would print module name at the beginning of the message. 

If the modules are used in scripts, it is sometimes difficult to
identify, which C-module, used in the script, caused some problem or is
printing the message. This is the case for e.g. r.report (file stats.c)
too.

What about adding G_program_name(); to every message, so that 

    G_message("Hallo, world!");
    
would produce

    g.module: Hallo, world!

and
    G_warning("Hallo, world!"); -> WARNING: g.module: Hallo, world!

??

The question is, how to do it... Imho the best place is printf_error();
in error.c

What do you think?

Jachym
