Mike Innes just helped us come up with a neat little hack, that let me
capture the file and line # info in a macro (it really *shouldn't* require
a hack though, something needs to be done to fix #9577).
_lin(a::Expr) = a.args[2].args[1].args[1]
_fil(a::Expr) = string(a.args[2].args[1].args[2])
_err(a::Expr) = a.args[2].args[2]
macro warn(a)
quote
log(Warning, $(esc(:Symbol))($(_fil(a))), $(_lin(a)), $(_err(a)))
end
end
and it is called with this way:
const ERR_STATUS_CODE = 42
...
@warn(()->ERR_STATUS_CODE)
The anonymous function is never even created, it's just parsed, and has the
file/line info added, and then the macro code grabs the information placed
there.
