I'm no guru here, but here's a solution that works if your functions are
_not_ defined inside objects. The idea is:
1. capture current System/words
2. Load the script(s)
3. Examine new words added to system/words. Those of type Function! are what
you are after.
Sample code, including showing the object/function shortcoming:
;; Capture existing words
existing-words: copy first system/words
;; ---- run a script that does the following:
myfunc: func [] [print 1]
myobj: make object! [myobjfunc: func [] [print 2]]
;; Spot the new words
new-words: sort difference existing-words first system/words
foreach new-word new-words [
print [new-word type? get to-word new-word]
]
I don't know an easy way to tell if a word has changed -- but if you are
running an untrusted script, 'protect has got to be basic insurance.....I
suppose you could make a block of all words which are functions, and their
molded checksum. After loading the script, check again to see if they are
still functions with the same checksum.
But protect _that_ block (or make it local) and all the words you need to
check the checksums. Otherwise your checking could be subverted (My code
above naively assumes that 'sort, 'difference, etc retain their expected
meaning after running your script).
