[REBOL] Calling local functions from parse rules...
From: carl::cybercraft::co::nz at: 29-Mar-2002 21:02
I'm trying to write a function that does some parsing within it and
the parse rules require a local function to be called, but I can't get
parse to recognise the function. Here's an example of the problem...
parse-this: func [blk rules /local str local-func value][
str: copy ""
local-func: func [n][append str n]
parse blk rules
Which give this error...
>> parse-this ["abc"][set value string! (local-func value)]
** Script Error: local-func has no value
** Where: parse-this
** Near: local-func value
How do I get it to recognise 'local-func without making 'local-func a
global function? By using 'bind perhaps? But how? No way I've
tried has worked.
Also, 'value in the parse rule there becomes global...
>> ? value
VALUE is a string of value: "abc"
I want that kept local to the function too. Any help appreciated...
