[Rubycocoa-talk] OSX::NSAppleEventDescriptor.data

[Yvon T. <tho...@fr...>]

Hey all,

i want to use the Apple Event Manager iget URL.

i've allready started to implement the "(void)handleGetURLEvent: 
(NSAppleEventDescriptor *)event withReplyEvent: 
(NSAppleEventDescriptor *)replyEvent"
in ruby. This method is called when a type-in something like :

bmkm:0000000000

in the url field of Safaro or Firefox.

the ADC page on that subject says :

> Listing 3  Implementation of a get URL Apple event handler
>
> - (void)handleGetURLEvent:(NSAppleEventDescriptor *)event  
> withReplyEvent:(NSAppleEventDescriptor *)replyEvent
>
> {
>
>     // Extract the URL from the Apple event and handle it here.
>
> }

which is a bit short and doen't explain at all how to extract the Url.

after some expiremntal work, i've found i've to look at  
"OSX::NSAppleEventDescriptor.data", it's where i am.

if i print-out the event.data.class i get : OSX::OCObject.

then, if i print-out it's value i get (shorted) :


<646c6532 00000000 61657674 00000138 00000000 00000000 [...]
626d6b6d 3a303030 30303030 30303000 >

after i typed in safari "bmkm:0000000000"  (ten zeros)

the ten lasts "30" is the hex code of the ascii char "0" (zero).

i've verified typing-in ten "1" and getting back ten "31".

how could i recover my string "bmkm:0000000000" from the above  
returned value ?

i think i have something to do with unpack ?
