[REBOL [
title: "a func with dumpable context :)"
author: "Elan, Volker"
purpose: {
[dump-func a-func] will source & dump locals, if defined
with debug-func (alias Elan's cfunc). you can set
func: :debug-func because there is a original-func
set too.
}
version: 0.0.0.4
file: %/home/volker/w/rebol/dump-func.r
date: 19-Aug-2000/13:32:44+1:00
]
if not value? 'original-func [original-func: :func]
dump-func: func ['f1] [
do compose [source (f1)]
f1: get f1
locals: copy first :f1
bind locals first second :f1
? locals
forall locals [if word? first locals [
probe first locals probe get first locals]]
]
[ ;Elan, bit modified
]
debug-func: func [spec body /local found] [
either found? found: find/tail spec /local [
insert found [function-self]
][
insert tail spec [/local function-self]
]
insert body [function-self]
make function! spec body
]
print "---"
f1: debug-func [a b] []
f1 "the a" "the b"
dump-func f1
f2: debug-func [/local a /opt b] [a: "in f2"]
f2
dump-func f2
[; or use func allways, but
func: :debug-func
func: :original-func
