The function deliver-keep-symbols
marks symbols such that they are not shaken out during delivery, and their names are kept.
This is useful for symbols that are not explicitly referenced by Lisp (and hence may be shaken out) but are still needed, for example symbols that are called directly from Java.
Using deliver-keep-symbols
has the same effect as passing :keep-symbols to deliver, but deliver-keep-symbols
is much more convenient because you can use it in your source code before loading the delivery module.
You will typically add a call to deliver-keep-symbols
after the definition(s) of the symbols, as in the example below.
(defun function-called-directly-from-java (x y)
.....
)
(deliver-keep-symbols
'function-called-directly-from-java)
