  • Why the HelloWorld of opennlp library works fine on Java but doesn't work with Jruby?

    - by 0x90
    I am getting this error: SyntaxError: hello.rb:13: syntax error, unexpected tIDENTIFIER public HelloWorld( InputStream data ) throws IOException { The HelloWorld.rb is: require "java" import java.io.FileInputStream; import java.io.InputStream; import java.io.IOException; import opennlp.tools.postag.POSModel; import opennlp.tools.postag.POSTaggerME; public class HelloWorld { private POSModel model; public HelloWorld( InputStream data ) throws IOException { setModel( new POSModel( data ) ); } public void run( String sentence ) { POSTaggerME tagger = new POSTaggerME( getModel() ); String[] words = sentence.split( "\\s+" ); String[] tags = tagger.tag( words ); double[] probs = tagger.probs(); for( int i = 0; i < tags.length; i++ ) { System.out.println( words[i] + " => " + tags[i] + " @ " + probs[i] ); } } private void setModel( POSModel model ) { this.model = model; } private POSModel getModel() { return this.model; } public static void main( String args[] ) throws IOException { if( args.length < 2 ) { System.out.println( "HelloWord <file> \"sentence to tag\"" ); return; } InputStream is = new FileInputStream( args[0] ); HelloWorld hw = new HelloWorld( is ); is.close(); hw.run( args[1] ); } } when running ruby HelloWorld.rb "I am trying to make it work" when I run the HelloWorld.java "I am trying to make it work" it works perfectly, of course the .java doesn't contain the require java statement.

  • Macports and virtualenv site-packages Fallback

    - by Streeter
    I've installed django and python as this link suggested with macports. However, I'd like to use virtualenv to install more packages. My understanding is that if I do not pass in the --no-site-packages to virtualenv, I should get the currently installed packages in addition to whatever packages I install into the virtual environment. Is this correct? As an example, I've installed django through macports and then create a virtual environment, but I cannot import django from within that virtual environment: [streeter@mordecai]:~$ mkvirtualenv django-test New python executable in django-test/bin/python Installing setuptools............done. ... (django-test)[streeter@mordecai]:~$ pip install django-debug-toolbar Downloading/unpacking django-debug-toolbar Downloading django-debug-toolbar-0.8.4.tar.gz (80Kb): 80Kb downloaded Running setup.py egg_info for package django-debug-toolbar Installing collected packages: django-debug-toolbar Running setup.py install for django-debug-toolbar Successfully installed django-debug-toolbar Cleaning up... (django-test)[streeter@mordecai]:~$ python Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import django Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named django >>> So I can install packages into the virtual environment, but it isn't picking up the global site-packages. Or am I not doing something correctly / missing something / misunderstanding how virtualenv works? I've got Mac OS 10.6 (Snow Leopard), have updated my macports packages and am using macports' python26 (via python_select python26).

  • Mac OS X 10.5+ and POSIX

    - by Phil
    Hello, I need to program an authentication module that has to work with Mac OS X 10.6 Snow Leopard and at the same time needs to be POSIX-compliant. I read here: developer.apple.com/leopard/overview/osfoundations.html that since Mac OS X 10.5 Leopard, Mac OS X is POSIX-compliant (to POSIX 1003.1), but working under MAC OS X 10.5 Leopard myself, I can't find any trace of my user name neither in /etc/passwd nor in its successor /etc/master.passwd, which is mentioned here: developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/ManPages/man5/passwd.5.html Instead it says in both files OpenDirectory Service is used, which should be OpenLDAP according to the OpenDirectoryService man-page. Is this still POSIX-compliant ? I guess not. I wonder how Mac OS X would handle my 100% POSIX-compliant code which depends on /etc/passwd ? I would be gratefull if someone could explain the way this works to me. Thank you for your time and trouble. Best regards Phil.

  • how do you create a simple obejctice-c command line project in xcode

    - by Mark
    im moving from a c# VS2008 world into the mac world and I just wanted to know how I can create a quick little command line based application so that I can write many little objective-c apps without worrying about creating an iPhone app or whatever. Which projects do I create in xcode? I can see the Command Line Tool under "Mac os x" but the only options for the type is "C", "C++", "Core Data", "Core Foundation", "Core Services" and "Foundation" but no simple objective c project? Thanks

  • svn for eclipse on mac os lion

    - by camdaochemgio
    I need to use Subversion with Eclipse on Mac Lion. I encounter problem as below I saw: Subclipse in Mac OS Lion In my context: I use Mac OS Line 10.7.2 Eclipse version: 3.7.1 64 bit I install Subversion: Universal Subversion 1.6.17 Binaries for Lion (Mac OS X 10.7) in the page: http://www.open.collab.net/downloads/community/ I install Subclipse by the "Install New Software..." feature of Eclipse with the update link: http://subclipse.tigris.org/update_1.8.x It install Subclipse 1.8.2, JavaHL 1.7.1.1 and some other packages. When I go to menu Preferences/ Team / SVN , it produce error: "Incompatible JavaHL library loaded. 1.7.x or later required." I find to install SVN Kit, so use it instead of JavaHL as the very first link refer (here), but I don't see it in Subclipse package.

  • Window bounds set on window using AppleScript in OS X are being ignored

    - by Jesse
    I am trying to create a small AppleScript to create and move some Terminal windows around my screen. The problem I am running into is that in some cases, it seems that OS X is ignoring the bounds I am setting. Using the AppleScript Editor: tell application "Terminal" to set the bounds of the first window to {0, 50, 600, 700} tell application "Terminal" to get the bounds of the first window Shows the following in the Event Log: tell application "Terminal" activate set bounds of window 1 to {0, 50, 600, 700} get bounds of window 1 --> {0, 22, 600, 672} end tell Result: {0, 22, 600, 672} Visually inspecting the window that is created when the script runs shows that Result bounds are the ones being used by the window. Any ideas?

  • NSPopupButton Bindings with Value Transformer

    - by rdelmar
    I don't know if what I see with a popup button populated by bindings with a value transformer is the way it's supposed to be or not -- the unusual thing I'm seeing (at least with respect to what I've seen with value transformers and table views) is that the "value" parameter in the transformedValue: method is the whole array bound to the array controller, not the individual strings in the array. When I've done this with table views, the transformer is called once for each displayed row in the table, and the "value" parameter is whatever object is bound to that row and column, not the whole array that serves as the content array for the array controller. I have a very simple app to test this. In the app delegate there is this: +(void)initialize { RDTransformer *transformer = [[RDTransformer alloc] init]; [NSValueTransformer setValueTransformer:transformer forName:@"testTransformer"]; } - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { self.theData = @[@{@"name":@"William", @"age":@"24"},@{@"name":@"Thomas", @"age":@"23"},@{@"name":@"Alexander", @"age":@"64"},@{@"name":@"James", @"age":@"47"}]; } In the RDTransformer class is this: + (Class)transformedValueClass { return [NSString class]; } +(BOOL)allowsReverseTransformation { return NO; } -(id)transformedValue:(id)value { NSLog(@"%@",value); return value; } In IB, I added an NSPopupButton to the window and an array controller to the objects list. The content array of the controller is bound to App Delegate.theData, and the Content Values of the popup button is bound to Array Controller.arrangedObjects.name with the value transformer, testTransformer. When I run the program, the log from the transformedValue: method is this: 2012-09-19 20:31:39.975 PopupBindingWithTransformer[793:303] ( ) 2012-09-19 20:31:40.019 PopupBindingWithTransformer[793:303] ( William, Thomas, Alexander, James ) This doesn't seem to be other people's experience from what I can see on SO. Is there something I'm doing wrong with either the bindings or the value transformer?

  • MAAttachedWindow hide

    - by Montecorte
    I had the same problem that The-Kenny at this post but I fixed it adding the windowDidResignKey: method on the MAAttachedWindow.m, but now my problem is that when I click outside the StatusBar item keeps blue background and when I click another time on the status item it goes normally and I have to click a second time on it to show the window. I tried to add a method in the CustomView (the view of the status item) that do the same thing that te mouseDown method: - (void)mouseDown:(NSEvent *)event { NSRect frame = [[self window] frame]; NSPoint pt = NSMakePoint(NSMidX(frame), NSMidY(frame)); NSLog(@"%g,%g",pt.x,pt.y); clicked = !clicked; [controller toggleAttachedWindowAtPoint:pt]; [self setNeedsDisplay:YES];} my method is: - (void)windowDidResignKey { NSLog(@"Resigned"); NSRect frame = [[self window] frame]; NSPoint pt = NSMakePoint(NSMidX(frame), NSMidY(frame)); NSLog(@"%g,%g",pt.x,pt.y); clicked = !clicked; [controller toggleAttachedWindowAtPoint:pt]; [self setNeedsDisplay:YES];} I call this method in the windowDidResignKey that I have defined on MAAttachedWindow.m, but this method dont call correctly the toggleAttachedWindowAtPoint method, I dont know exactly why, it's only called when I click another time over the status item If anybody knows how to do that any help would be fine. Thank you so much :)

  • Rubygame on OS X shebang problem

    - by Mk12
    I'm playing around with Rubygame. I installed it with the Mac Pack, and now I have the rsdl executable. rsdl game.rb works fine, but when I chmod +x the rb file, add the shebang to rsdl (tried direct path and /usr/bin/env rsdl) and try to execute it (./game.rb), it starts to flicker between the Terminal and rsdl which is trying to open, and eventually gives up and gives a bus error. Anyone know what's causing that? I'm on Snow Leopard (10.6.2) if it makes a difference. Thanks.

  • Any simple way to "resize" an NSBezierPath?

    - by d11wtq
    I have an NSBezierPath that I'm filling and stroking. I'd like to add some inner glow to the path (a light stroke, just inside of the outer stroke), and the thing that comes to mind is to use the same path shrunk by 1 pixel (the size of the line that is already )stroked. Is there a way to do this? Alternatively, is there some sort of pattern I can use when applying both a border (stroke) and a glow to a bezier path? Example, the (extremely subtle) inner glow on the Google Chrome tabs:

  • How to make Mac OS X CrashReporter invoke debugger?

    - by StasM
    I have an appache module on Mac OS X that produces random crashes. I can reproduce these crashes with certain sequence of actions, and these crashes produce Crash Reporter dialog "httpd quit unexpectedly". Is there a way to cause Crash Reporter launch debugger (xcode, gdb, anything) instead of just displaying the backtrace? I've tried running httpd under gdb with httpd -X but the crash doesn't happen then - it happens only if many httpd's are running at once, and I found no way to attach gdb to all of them at once. So I was hoping maybe I can cause CrashReporter to attach the debugger when specific process crashes - is there a way to do it?
