Dear All,

In attempting to learn and use code generation, it
would be useful to be able to view the source code
that gets generated.

However, with various combinations of templates, UDAs, and
mixins it has not been easy.

Is there some standard way this is done?

Optimal would be to print out the entire generated source
code to allow inspection.

Best Regards,
James

Use the `mixin` compiler flag

`dmd -mixin=<whatever-name> file.d`

Beware, this will also include **all** the mixin code from 
standard library and runtime.

But it's manageable, reflecting on my experience.

Tejas,

Thank you for your kind response.  Wow, at first the large output 
file
from a small test program was a bit surprising .., but actually 
it is
manageable to dig through to find the interesting bits.

So, this is quite useful!  Thanks again, now I am off to do some 
digging...

Best Regards,
James

Note that that will only give the expansions from string mixins, 
not from template mixins, templates and other things.

Apart from -mixin, there's also the undocumented -vcg-ast switch 
that prints the AST before code generation, showing instantiated 
templates and unrolled static foreach loops.
