Hi all,
I was discussing this with Stefan Koch and a few other people at
DConf - would it be possible to have a compiler switch for
outputting the complete source file after the mixins have been
expanded, similar to gcc -E?
I assume that mixin expansion occurs in the semantic pass, which
might make this difficult; however, it'd be pretty useful,
especially when working on heavily CTFE-dependent code where
almost everything is generated at compile-time; while you can
splatter pragma(msg) around, it can get rather tedious,
especially when debugging.
A quick look at CompileStatement.semantic indicates that the
string is parsed, with the resulting statements made the subject
of a CompoundStatement - at this point, I'm assuming the AST has
already been processed (lowering, etc), making it difficult to
recover the original source code from the AST. Perhaps it would
be possible to splice in the mixin string into the original
source?
