Yes, I was aware of this. As I said, *i was reading the [build-menu]*. 
The question was: how to distinguish errors from warnings and notices? I 
would like Geany to display errors in red, warnings in blue and notices 
in green. Is that possible? Unfortunately, the link you sent says 
nothing about this.

I have also read 
http://www.geany.org/manual/hacking.html#error-message-parsing which says:

> New-style error message parsing is done with an extended GNU-style 
> regex stored in the filetypes.foo file - see the [build_settings] 
> information in the manual for details.

But it is not very helpful, since the manual on [build_settings] does 
not tell how to do it. (Or maybe there are two versions of that 
documentation and I'm looking at the wrong place?)

Thanks,
