Re: [MacRuby-devel] How do I subclass Obj-C classes in MacRuby?

[Thibault Martin-Lagardette]

Hi!

I believe the problem is that you were overriding the wrong init method. Here 
is what I changed to your code to make it work:

class MyNode < ODNode
def initWithSession(session, name:name, error:err)
if super
@session = session
self
end
end
end

session = ODSession.defaultSession
node = MyNode.nodeWithSession session, name: "/Local/Default", error: nil

I override initWithSession:name:error instead of init, and created a "MyNode" 
object the exact same way I would have created an ODNode :-)
The results were, I believe, what you would expect:

$> macruby od.rb 
{"dsAttrTypeStandard:AppleMetaNodeLocation"=>["/Local/Default"], ...}

Hope that helps!

Re: [MacRuby-devel] How do I subclass Obj-C classes in MacRuby?

[Thibault Martin-Lagardette]

Oh and by the way, you can generate BridgeSupport for CFOpenDirectory yourself 
if you need:

$> gen_bridge_metadata -f 
/System/Library/Frameworks/OpenDirectory.framework/Versions/A/Frameworks/CFOpenDirectory.framework
 -o CFOpenDirectory.bridgesupport

Then all you need to do is place `CFOpenDirectory.bridgesupport' wherever you 
need, and call from your script:

load_bridge_support_file '/path/to/CFOpenDirectory.bridgesupport'

And you should have access to `kODMatchEqualTo' etc.

Which should be available as  KODMatchEqualTo and not kODMatchEqualTo
(Ruby's constants start by an upper case letter)

Thanks, but unfortunately that doesn't actually help - there's no difference in 
use between that and not wrapping the object init... For example, what I'm 
doing currently is this -

module OpenDirectory
  class Node
attr_reader :node
def initialize config = { :node_name => "/Local/Default" }
  if config[:node_name].eql? "/Local/Default"
@session = ODSession.defaultSession
  else
@session = ODSession.sessionWithOptions config[:session_options], 
error:nil
  end
  @node = ODNode.nodeWithSession @session, name:config[:node_name], 
error:nil
end
  end
end

so I can either

local_node = OpenDirectory::Node.new

or

remote_node = OpenDirectory::Node.new proxy_config

where proxy_config is a hash containing info for a DS remote connection to our 
directory master. I then access the ODNode as either local_node.node or 
remote_node.node where required. What I want to be able to do is just use 
local_node or remote_node as if they were ODNode objects (or subclasses of 
ODNode) to remove the ruby proxying wrapper around the core Obj-C objects, but 
still hide the ugliness of OpenDirectory behind some simpler Model style 
wrappers.

(I hope that makes sense)

cheers

[MacRuby-devel] Comparison between String and nil fails.

[Michel Steuwer]

Hi everyone,
yesterday i migrated my little MacRuby project to 0.6 and i found a kind of 
strange behavior in a comparison between a string and nil. In MacRuby 0.5 the 
line worked as expected.
I get the following error message in a comparison between a string on the left 
and nil on the right:
can't convert nil into String (TypeError)

I made a little demo project to show the problem.
The string i want to compare comes out of a userInfo dictionary i get when 
iTunes send a notification through the NSDistributredNotificationCenter.
In the demo project the error occurs, if you play, pause, or skip a song in 
iTunes (every time i get a notification from iTunes).

So here the code in which the error occurs:

def songChanged(notification)
NSLog("notification.userInfo[Name]  
#{notification.userInfo['Name']}.")
NSLog("notification.userInfo[Name].nil? 
#{notification.userInfo['Name'].nil?}.")
NSLog("notification.userInfo[Name].class
#{notification.userInfo['Name'].class}.")
NSLog("notification.userInfo[Name] != nil   
#{notification.userInfo['Name'] != nil}")
end

The method receives a notification from iTunes and the last line in the method 
fails ( notification.userInfo['Name'] != nil ).

I don't know where the problem is, but i guess the comparison should just 
return false. One again, in MacRuby 0.5 the line worked as expected.

You can find the hole demo project at:
http://github.com/michelSt/MacRubyBug

Thanks,
Michel

Re: [MacRuby-devel] Aaron answer about convert the code of the Book to MacRuby

[Christian Bryan]

Daniel, 

I have the RandomApp example from chapter 2, which I will add to the 
fork. Chapter 4 was about manual memory management using the retain/release 
mechanism and is not really applicable to a MacRubyist. Chapter 3 I skipped, 
probably due to realising that converting the LotteryEntry class and the 'main' 
function to idiomatic ruby would be far too trivial to worth bothering about.

Cheers

[MacRuby-devel] Passing a string buffer to a C function

[Mike Taylor]

Hi all, 

I'm trying to do some GLSL shaders with MacRuby. However, I'm a bit stumped as 
to how to call glGetShaderInfoLog if the shader compilation fails. The C 
function's prototype is:

void glGetShaderInfoLog(GLuint shader, GLsizei maxLength, GLsizei * length, 
GLchar * infoLog);

I couldn't find any docs on how Pointer.new_with_type, so I tried a few things, 
such as:

log_info = Pointer.new_with_type('c', 4096)
length = Pointer.new_with_type('i')

glGetShaderInfoLog(@shader_id, 4096, length, log_info)

However, I get the error:

TypeError: can't convert Pointer into String

It seems that the bridge wants log_info to be a String object. But, using a 
String causes a bus error. I'm expecting that the bridge isn't expecting the 
string to be mutated.

Any suggestions would be appreciated!

Re: [MacRuby-devel] How do I subclass Obj-C classes in MacRuby?

[Thibault Martin-Lagardette]

Hi!

What you can do is a "factory" just like this:

module OpenDirectory
class Node < ODNode
def self.create(config = { :node_name => "/Local/Default" })
if config[:node_name].eql? "/Local/Default"
session = ODSession.defaultSession
else
session = ODSession.sessionWithOptions 
config[:session_options], error:nil
end
return self.nodeWithSession session, name:config[:node_name], 
error:nil
end

def initWithSession(session, name:name, error:err)
if super
@session = session
self
end
end
end
end

And then call:

local_node = OpenDirectory::Node.create
remote_node = OpenDirectory::Node.create proxy_config

And then you can pass these nodes directly to the OD methods :-)

You can also do a more Cocoa-ish way:

def self.nodeWithConfig(config)
config ||= { :node_name => "/Local/Default" }
if config[:node_name].eql? "/Local/Default"
session = ODSession.defaultSession
else
session = ODSession.sessionWithOptions 
config[:session_options], error:nil
end
return self.nodeWithSession session, name:config[:node_name], 
error:nil
end

Then you can OpenDirectory::Node.nodeWithConfig(nil) or 
OpenDirectory::Node.nodeWithConfig(proxy_config).
You could even just call OpenDirectory::Node.nodeWithConfig(config), whether 
it's a proxy config or nothing :-)

Hope that helps!

 Had a problem with Interface Builder parsing a XCode project using
 MacRuby. Raised a bug in Radar but Apple Engineering have responded that
 the issue is with macruby. Therefore raised as a ticket here. Full text of
 email thread reproduced below:

 Hi Timothy,

 This is a courtesy email regarding Bug ID# 7464509.

 Engineering has determined that this issue originates with MacRuby
 mailing-list.

 There is information here: http://www.macruby.org/contact-us.html

 The IB parser has been tested many times recently (especially the last few
 days), so we would be tempted to say that this is a problem with the
 project.

 Bug reports requiring your attention will appear under ‘My Originated
 Problems’.  Please review this bug report and provide the requested
 information via the Apple Bug Reporter. Once your report has been updated,
 Engineering will be alerted of the new information.

 

 Thank you for your assistance in helping us discover and isolate bugs
 within our products.

 Bug ID #: 7464509
 Bug Title: IB fails to read classfile in Ruby Cocoa project
 ---
 
 Summary:
 I have a Ruby Cocoa application project created using the template. At
 first IB was correctly seeing the .rb file as a class and discovering its
 outlets. But it has stopped doing so. Now if I select File->Read Class
 Files to force a re-read it parses the file then shows a red dimple in the
 IB project window at the bottom and displays an error message saying
 "Parsed 1 source file, but no classes were found or changed".

 I tried editing the source .rb and saving it. I also closed and reopened
 both IB and XCode but IB will not read the source any more.

 I did a Clean Build at some point before this behaviour started that could
 be related although I have no evidence to show that this was the cause.

 Steps to Reproduce:
 1. Create a Ruby Cocoa project
 2. Create a .rb class add some code and save it
 3. Add some GUI objects eg buttons, popups, etc to the window in the main
 NIB
 4. Add an Object to the NIB project window from the Library
 5. Show the inspector, go the Identity tab and look  for the ruby class in
 the Class popup

 Expected Results:
 The .rb class should show up and be selectable to set the class as the
 type of the object added to the IB project in step 4

 Actual Results:

 IB completely refuses to see the .rb as a class.
 Also editing and saving the .rb file in XCode, reopening the apps or
 File->Reread class files should all cause a sync between XCode and IB. The
 .rb should then show up in the popup. It doesn't as described.

 Regression:
 none

 Notes:
 Please note that the project was working normally. Then it stopped working
 for no obvious reason.
 I can provide the project zipped up if required. But the code is
 proprietary (I am doing contract work for a client) so confidentiality
 would need to be respected in that case.

 
 Yes I can see the class in the classes tab of the IB Library window. It
 shows as a blue cube. The Lineage, Definitions, Outlets and Actions tabs
 also show what appears to be correct content yet the bug as described on
 File -> Read Class Files persists.

 
 'GenRegData.zip' was successfully uploaded

 
 See attached. I have obfuscated the code to protect client confidentiality
 but the problem was still present.

[MacRuby-devel] NSObject.to_s question

[Jordan Breeding]

Right now for custom objects on the Objective-C side even if you provide a 
-[Object description] call to_s will fall through and hit to_s from NSObject 
which right now just has the class name and pointer.

Is it already planned for the future to use the description method in to_s on 
the MacRuby side? Should I file a bug report?

Re: [MacRuby-devel] Passing a string buffer to a C function

[Laurent Sansonetti]

Hi Mike,

Thanks for the report. I think this is because GLchar* is typed in the runtime 
as a C-style string. The compiler should allow Pointer objects for this runtime 
type. Currently, it only allows nil, symbols and strings.

Could you file a bug? We will track this...

Thanks,

Laurent

 The MacRuby runtime does not allow calls to C functions that take a string
 buffer using Pointer types. So, any C functions that need to fill a string
 buffer cannot be called.

 For example, I'm trying to do some GLSL shaders with MacRuby. I cannot
 call glGetShaderInfoLog if the shader compilation fails. The C function's
 prototype is:

 void glGetShaderInfoLog(GLuint shader, GLsizei maxLength, GLsizei *
 length, GLchar * infoLog);

 I couldn't find any docs on how Pointer.new_with_type, so I tried a few
 things, such as:

 log_info = Pointer.new_with_type('c', 4096)
 length = Pointer.new_with_type('i')

 glGetShaderInfoLog(@shader_id, 4096, length, log_info)

 However, I get the error:

 TypeError: can't convert Pointer into String

 It seems that the bridge wants log_info to be a String object. But, using
 a String causes a bus error. I'm expecting that the bridge isn't expecting
 the string to be mutated.

 I have embedded MacRuby in my app using the macruby_deploy script, but it
 still tries to load library files from /Library/Frameworks.

 In the case of C extensions, this actually caused libmacruby.dylib to be
 loaded twice, which is bad.

 I worked around this by changing the RUBY_LIB before initializing MacRuby.

 Shouldn't MacRuby set up it's path relative to the framework from which it
 is loaded?

 Here's a program:

 Cocoa" before the "gem test-unit".

 Another fun way to make it consistently exit successfully is to replace
 "require test/unit' with the *contents* of that file.

 Even though there's a simple workaround, I'm calling it "major" because
 the workaround is hard to find.

[MacRuby-devel] FTP in MacRuby

[Daniel Fontaine]

Does Net::FTP not work on MacRuby 0.6? I am trying a simple 
Net::FTP.new(server, user, password) and receive

EOFError: end of file reached
from 
/Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/1.9.0/monitor.rb:188:in
 `synchronize'
from 
/Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/1.9.0/monitor.rb:188:in
 `synchronize'

The same method works fine under standard ruby.

I am new to MacRuby, so sorry if this is a known issue.

thanks,
Dan

Re: [MacRuby-devel] NSObject.to_s question

[B. Ohr]

Jordan,

you can do something like that:

class Object
  alias :old_inspect :inspect
 
  def inspect
i = old_inspect
if i.start_with?('#<')
  d = description
  d.start_with?('<') ? i : d
else
  i
end
  end
end

But you’re right, a better integration of „description“ would be nice.

[Jordan Breeding]

Yeah, I was doing something similar right now, just hoping for a better long 
term solution in MacRuby.

Hi Laurent,

What would be a feasible workaround for this problem, given than I'm using 
MacRuby 0.5 ?

i.e. I'm also trying to call:

CTFramesetterCreateFrame(framesetter, CFRangeMake(0, 0), path, nil)

The second argument is a range which produces the error.

Can I edit the bridge support file? Or is there some other workaround? Can I 
use a more recent built of MacRuby? Or are these too buggy compared to 0.5?

Thanks,
Paul Howson

Do you have any reason why you cannot use 0.6? It's much stabler than 0.5 :)

[MacRuby-devel] v0.7 and v0.6 timeout problem

[B. Ohr]

Hi, I have strange timeout problems with 0.6 and 0.7

$ time macruby_select 0.7 -e 'framework "Cocoa"'
2010-05-06 07:03:55.018 macruby[1922:607] 
__CFServiceControllerBeginPBSLoadForLocalizations timed out while talking to pbs
real0m1.588s
user0m0.699s
sys 0m0.096s

0.6 takes even longer:

$ time macruby_select 0.6 -e 'framework "Cocoa"'
2010-05-06 07:03:43.672 macruby[1913:607] 
__CFServiceControllerBeginPBSLoadForLocalizations timed out while talking to pbs
real0m2.170s
user0m0.698s
sys 0m0.102s

while 0.5 has no timeout:

$ time macruby_select 0.5 -e 'framework "Cocoa“‘
real0m0.398s
user0m0.380s
sys 0m0.057s

I’m still on OS X Version 10.6.2, is that the reason?

In the meantime I removed the MacRuby runtimes ala Matt Aimonetti, but that 
did’nt help.
