[REBOL] Re: Setting Block Data
From: mdb:gci at: 22-Nov-2000 16:19
Hello Mike,
An interesting problem, still got me stumped but i managed to come up
with this partial solution:
set-field: func [a v] [do form reduce [to-set-path a v]]
>> info: [db [[detail "detail one"] [detail "detail two"]]]
== [db [[detail "detail one"] [detail "detail two"]]]
>> set-field "info db 1 detail" 444
== [detail 444]
>> set-field "info db 2 detail" 555
== [detail 555]
>> info
== [db [[detail 444] [detail 555]]]
>>
but only seems to work with numbers and not strings ?
I'm very interested to see if you find a solution.
Mike.
===========================================
I am trying the following:
info: [
db [
[ detail "detail one" ]
[ detail "detail two" ]
]
]
set-field: func [ apath [path!] v ] [
do [ to-set-path reduce [ :apath 'detail ] :v ]
]
>> set-field 'info/db/1 "newdata"
== "newdata"
>> info
== [
db [
[detail "detail one"]
[detail "detail two"]
]
]
I was hoping to change the value assigned to info/db/1/detail . Does
anyone
have any ideas?
