[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 ?

I think definitely N is correct. On PowerPC there is no difference  
between N and L. However, if your code were to run on an Intel mac,  
it would not work if you used L.

i did some try-out :

with 'GURL'.unpack('N')[0] (changing only L to N) i got :
"handleGetURLEvent_withReplyEvent(event, replyEvent)"
from :
   def handleGetURLEvent_withReplyEvent(event, replyEvent)
     p "handleGetURLEvent_withReplyEvent(event, replyEvent)"
   end

then N works as well as L.

i've tried also :

'gurl'.unpack('N')[0]

which failed to work.

i've read on a pyton list that it is GURL definitely.

for the difference between N and L i must investigate further because =20=

i didn't pass any arg for the time being, i need just a string as it =20
is done with the man:  protocol able, on Safari, using Sogudi, to =20

Do you mean you have got it working?

> it remains to me understanding why it is "#unpack('L')[0]"

The constants are defined as 'abcd' in the C header file. 'abcd' is  
non-standard C syntax for a multi character literal integer,  
interpreted as four bytes 'a' 'b' 'c' and 'd', with 'a' being the  
most significant byte.

Given these as a ruby string 'abcd', treating the four string bytes  
as an unsigned long gives the appropriate value.

Having originally suggested the format specifier 'L' for unpack, I  
realise now it should actually be 'N', which treats the data in the  
correct order. The 'L' code would work properly on PowerPC, but not  
Intel.

So 'gurl'.unpack('N')[0].

[Rubycocoa-talk] NSAlert (sheet) and contextInfo

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

Hey all,

i'm using an NSAlert as a sheet then i need to pass some args within  
contextInfo in order to know what to do within  
"#alertDidEnd_returnCode_contextInfo(alert, returnCode, contextInfo)"  
for example what method to call with which objects.

i had a look about the class of the returned contextInfo giving :

contextInfo.class = OSX::ObjcPtr  (presumably an Obj-C Pointer) ?

my first try used a string as a contextInfo : "this is the contextInfo".

the value returned by contextInfo.to_s was : #<OSX::ObjcPtr:0x3b3f510>

is their a way to transform that into a ruby object ?

as for example using #to_rbobj ???

the better for me would be to pass a method with it's associated args  
for example :

saveFile("thisFileName")

how could i implement that with contextInfo ???

it is 'GURL' not 'gurl' working...

it remains to me understanding why it is "#unpack('L')[0]"

i've understood what is unpack['L']

according to <http://www.rubycentral.com/book/=20

L  	Treat four1 successive characters as an unsigned native long =20

even if i put :

in the method :

also Apple says the best place is to put that in =20

If your handler is called 'handleGetURLEvent_withReplyEvent', then  
the 'andSelector' argument above must be  
'handleGetURLEvent:withReplyEvent:'. i.e.:

    
appleEventManager.setEventHandler_andSelector_forEventClass_andEventID 
(self,
'handleGetURLEvent:withReplyEvent:',  'gurl'.unpack('L')[0],   
'gurl'.unpack('L')[0])

Ah, sorry. __ocid__ is what I was looking for. However, this is an

[Rubycocoa-talk] Apple Event Manger get URL and handleGetURLEvent_withReplyEvent(event, replyEvent)

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

Hey all,

following Jonathan advices i've put in "awakeFromNib" :


     @appleEventManager=OSX::NSAppleEventManager.sharedAppleEventManager
      
@appleEventManager.setEventHandler_andSelector_forEventClass_andEventID( 
self, 'GURL',  'gurl'.unpack('L')[0].to_i,  'gurl'.unpack('L')[0].to_i)


however the following :

   def handleGetURLEvent_withReplyEvent(event, replyEvent)
     p "handleGetURLEvent_withReplyEvent(event, replyEvent)"
   end

is never called, even if i type in the Safari' url field "bmkm:blahblah"

the application get frontmost then "bmkm:" is recognize by the Apple  
Event Manager send to the correct app (in case it isn't running the  
app shows up).

some light upon that ?

however, using hash it's ok, without any tag value... :

button =3D (textField.hash =3D=3D @iPAddressField.hash) ? =
@hostNameButton : =20
@iPAddressButton

that's not a big prob, better to know.

I think that's a limitation of how RubyCocoa operates at the moment.  
I have a patch in the works for it, but unfinished as yet. You could  
try:

   foo.oc_id == bar.oc_id

'oc_id' refers to the native objective c object value.

> I found that surprising too!

something surprising also is object comparison here it is :

in Obj-C :

- (void)controlTextDidChange:(NSNotification *)notification
{
     NSControl *textField;
     NSButton *button;

     // get the field that is sending the notification
     textField =3D [notification object];
     // get the button that corresponds to the field
     button =3D (textField =3D=3D IPAddressField) ? hostNameButton : =20
IPAddressButton; #### <=3D=3D=3D HERE
     // disable that button if the field is empty
     [[textField stringValue] isEqualToString:@""] ? [button =20
setEnabled:NO] : [button setEnabled:YES];
}

if i translate to :

     def controlTextDidChange(notification)
       textField=3Dnotification.object
       button =3D (textField =3D=3D @iPAddressField) ? @hostNameButton : =
=20
@iPAddressButton #### <=3D=3D=3D HERE
       (textField.stringValue.to_s =3D=3D "")? button.setEnabled(false) =
: =20
button.setEnabled(true)
       button.oc_display
     end

the comparison ("(textField =3D=3D @iPAddressField)") returns always =20
false, meaning a notification.object coundn't be the "same" object as =20=

@iPAddressField ???

(never got that strange behaviour in Cocoa-Java, may be i'm wrong in =20
the ruby side)

then, i had to add two different tag values in Inteface Builder giving :

     def controlTextDidChange(notification)
       textField=3Dnotification.object
       button =3D (textField.tag.to_i =3D=3D @iPAddressField.tag.to_i) ? =
=20
@hostNameButton : @iPAddressButton #### <=3D=3D=3D HERE
       (textField.stringValue.to_s =3D=3D "")? button.setEnabled(false) =
: =20
button.setEnabled(true)
       button.oc_display
     end

and that works.

then it seems the reference of those two object coudn't be the same =20
in RubyCoca, even if they're the same object ????

again, i feel i'm misunderstanding something for that particular point.

in the same area, i've found that an "ib_outlet" could only start =20

Hmmn. The file you need is:

/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ 
Frameworks/AE.framework/Versions/A/Headers/AERegistry.h

Command-double-click is the same as control-click (context menu) ->

ok, i need first to find a way to read headers by command double-=20

     host =3D [NSHost currentHost];

The case of the file name doesn't matter, but...

Class names must start with a capital [1]. The rails trend appears to  
be naming the file in the lowercase_underscores scheme. So a class  
called MyImportantThing would go in my_important_thing.rb.

I think so! :)


[1] This is because classes get assigned to a constant, and constants  
in ruby must start with a capital letter.

right ! i don't think i'll standalonify this try-out "NameAndAddress"

also i've find that i can't named the "nameAndAddress.rb" because =20
this is a class and must start with an upper letter.

otherwise you get the error message :

/Users/yvon/work/CocoaRubyfication/NameAndAddress/build/Default/=20
NameAndAddress.app/Contents/Resources/nameAndAddress_main.rb:16:in =20
`require': /Users/yvon/work/CocoaRubyfication/NameAndAddress/build/=20
Default/NameAndAddress.app/Contents/Resources/nameAndAddress.rb:21: =20
class/module name must be CONSTANT (SyntaxError)
class nameAndAddress < OSX::NSObject


Am I discovering Ruby ?

best,

I found that surprising too!

I would say it's probably not worth changing 'rb_main.rb' - the  
purpose of it is to load any other .rb files you have created. So  
just make yourfile.rb and it'll get loaded. Also, standaloneify.rb  
depends on file being called 'rb_main.rb' (because it patches the  
file before running the application).

Those constants aren't wrapped at the moment. But you can look them  
up yourself in the C header file. Try typing 'kAEInternetSuite' into  
the 'main.m' file (anywhere) and command-double-clicking on it. This  
should bring up the AERegistry.h header file:

   kAEInternetSuite              = 'gurl',
   kAEISGetURL                   = 'gurl',

(they happen to be the same). This will need to be converted to an  
integer, so you could try

  'gurl'.unpack('L')[0]
