There are two issues.
First:
what if the file foo.ss will have defined function foo.
(define (foo a b) (+ a b)))
(foo 1 2)
It makes error:
Got compile: unbound identifier (and no #%app syntax transformer is bound)
(#(struct:exn:fail:syntax compile: unbound identifier (and no #%app syntax
transformer is bound) #<continuation-mark-set>
This is a namespace issue. You need to create a namespace (with, e.g.,
(make-base-namespace)) and pass that as the 2nd optional argument to
eval-syntax. See the Guide and Reference for more detail.
Yes that helps
Second:
When function foo is defined correctly and called from the eval process and
errors occurs in foo, how can we find the caller's location in order to
format an error message?
I think whatever location information is available will be in the exception.
That the problem. The location will be location inside foo but not
location where foo was called from
