How to expand all macros of a script?

[MaxGyver83]

Is there a simple way to expand all macros of a script? Like gcc -E?

You can just parse the source script and macex on it.
Though note that it won't be super readable, and won't apply to modules (I'm pretty sure anyway).
Here's an example:

# test.janet
(do
  (print "hi")
  (%= 1 2))

# test2.janet
(def src (parse-all (slurp "test.janet")))
(pp src)
(pp (macex src))

janet test2.janet
# => @[(do (print "hi") (%= 1 2))]
# => @[(do (print "hi") (set 1 (<function %> 1 2)))]

Cool, thank you! Easier than I thought.
