Oh I certainly don't disagree with you that string mixins make this
kind of stuff extremely difficult to debug. It's even difficult for
the compiler to issue reasonable error messages; currently it seems to
issue errors within string mixins at (line of mixin expression + line
within string), which is usually completely bogus. However, if we're
going to solve the debugging issues with string mixins, we may as well
try to find a solution that would improve the handling of templates in
conjunction with debug info as well.
a possible sulution:
in a file Blah.d:83, we have following
mixin(compile_time_string);
1. write the compile_time_string to file \mixin\Blah\mixin_001.d ( 001 is
the id ) with the boilerplate: // mixed in file: Blah.d:83 (mixin LoC)
2. the debug info for the compile_time_string all points to that
\mixin\Blah\mixin_001.d
if we have more strings to be mixed in, we can simply increase the id 001
to 002, and generate another file into dir \mixin\Blah
For templates we can store them in
\template\Blah\template_templateName_templateArgs.d
