I starting digging in DMD for logic controlling behaviour of
assert(), especially whether it's possible to add automatic
printing of `lhs` and `rhs` upon assertion failure if
`AssertExp` is a binary expression say `lhs == rhs`.
After grepping for `AssertExp` the only possible place I could
think of was
ToElemVisitor::visit(AssertExp *ae)
inside
elem *toElem(Expression *e, IRState *irs)
in file e2ir.c.
Questions:
1. Is this the right place where this lhs-rhs-printing logic
should be added? If so could somebody tell me how to make this
happen?
2. Is it possible to from within DMD generate expressions that
do
`import std.stdio : write`
and then calls write on the `lhs` and `rsh`...or this a
completely wrong approach to solving this problem?
Someone will write something like this:
assert(plainPassword == plainPassword.toLower());
and plaintext passwords will end up in stderr.
