digitalmars.D.ide - Visual D DClosure mixin error?

This is a file in GtkD.

It says it's like 123 but it's actually line 121.

			swapped[0..n_param_values-1] = param_values[1..n_param_values];

		mixin(getCallbackCall!T()); // line 121 but stack trace says 
it's 123.

Seems it can't find the line nor the mixin in file correctly.

The main mixin does not seem to have this code in it either but 
it has other code related to other mixins from gtkD so it

Do you have gtk installed or are you willing to install it? The 
closure is generated for most event handling in gtkD it seems 
such as simple button click handling. Probably any gtkD example 
will produce such a stack.

I just tried it, and the rather new "Enable mixin debugging" feature on
the Compiler->Debug page is what you are looking for. This will write
the expanded mixins into the given file instead of the compiler just
making up random filenames.

Unfortunately, with "Separate compile and link" the link step overwrites
the file generated during compilation, so you should switch the
compilation model to "Combined compile and link" for the gtk library.

I had this checked already. I could debug mixins sometimes and it 
wrote them all to
one large file.

So something must be buggy. I guess it's not finding the file 
name correctly. Remember, it's also reporting the line number 
wrong.

Maybe it is a problem with the compiler itself and not Visual D? 
I searched for the DClosure in the large mixin file and could not 
find it but other related mixins were inside.

I do have combined enable. Separate compile and link is far too 
slow to be usable.

What is the file name it is not finding?

I suspect you have enabled mixin debugging for your project, but not gtkd.

"Separate compile and link" and "Combined compile and link" shouldn't
differ much, it's only about whether the linker is called directly or
through dmd.

"Single file compilation" is usually way too slow, and useful only under
special circumstances.
