I have a property I need to set with a dictionary. The obj.ns() method says it turns objects into dictionaries, but NSDictionary keys can be more than just strings. For example to configure video output settings, in Objective C I do this:

videoDataOutput.videoSettings = @{
    (id)kCVPixelBufferPixelFormatTypeKey: [NSNumber numberWithUnsignedInteger:kCVPixelFormatType_32BGRA]
};

I can't quite figure out how to construct the JS object to pass to obj.ns() to make this happen. Am I missing something?

I'm looking to create a block that takes an NSRange, and it seems I can't use a struct as a parameter, as I get TypeError: Unable to coerce type from [StructType] when supplying objc.types.NSRange as a type. Any ideas on how to do this? I'm also not sure how to create a block that takes primitives or the BOOL type (I'm trying to create a block of type ^(NSDictionary *attrs, NSRange range, BOOL *stop) {}

I'm trying to extract some data from a CGSize struct I got from a call to CVImageBufferGetDisplaySize.

I appear to be successfully calling the function that gives me the size for my image, using ffi:

const c = new ffi.Library(null, {
    CMSampleBufferGetImageBuffer: ['pointer', ['pointer']],
    CVImageBufferGetDisplaySize: ['pointer', ['pointer']]
});

The call to CVImageBufferGetDisplaySize returns a pointer to a CGSize struct. I want to convert that struct to a javascript object, but it's not clear how best to do that.

I tried adding the function NSStringFromCGSize to my ffi definition. It's a call that converts CGSize to a string representation, whereupon I could do some js mojo to get the values out of it.

But ffi can't find NSStringFromCGSize.

Not that this is the best way to do the conversion, but it seems like that should work.

So, really two questions:

1. How can i access global functions like NSStringFromCGSize from frameworks like UIKit in javascript?
2. Is there a better way to go about converting references to structs to javascript?

I want to convert nativeWindowHandle to NSView, like

const myView = win.getNativeWindowHandle()
$.myFramework.setView(myView)

any suggestion?

I'm getting an exception when calling
AVCaptureVideoDataOutput.setSampleBufferDelegate_queue_(delegate, queue).

While I am able to call other AVCaptureSession-related methods, this one throws an exception.

Two possible differences:

1. I am passing it my own custom class as a delegate.
2. I am passing it a dispatch_queue_t argument I got from calling dispatch_queue_create using ffi.

In both cases I may not entirely know what I'm doing, but I think I'm setting up these arguments correctly.

I distilled the problem down in this gist:

https://gist.github.com/jmbldwn/0ca994f69ed9f7d0e5adcef2bb4c1e4f

The exception is triggered by the call to runtime.msgSend(types[returnType], argumentTypes); at line 97 of instance.js.

Call stack:

Anything else I should be trying?

Hi, thanks for your work on this project!

I'm trying to work with CoreGraphics and can't see how to do that with objc

For example, I'm trying to call CGEventCreate(null) by writing:

const objc = require('objc')
objc.import('Cocoa')
objc.import('Framework')
const {CGEventCreate} = objc
const test = CGEventCreate(null)

but I'm getting back an error that CGEventCreate is not a function, and that it's value is 'H��AW'.

Any pointers for how to get this to work?

After importing IOKit using objc.import("IOKit"), it throws an error when attempting to access a function that would otherwise be a part of the library. For example, IOServiceMatching;

const objc = require("objc");

objc.import("IOKit");

const { IOServiceMatching } = objc; // => Err

Error stack:

Additional information:

• OS Version: macOS Monterey (12.1 Beta -> 21C5021h)
• TSC Version: 4.4.3
• Node Version: 16.9.0

I'm not sure if I'm just doing something incorrectly, or if it's not meant to do this.

UPDATE:

This will also fail, but with a different error:

const objc = require("objc");

objc.import("IOKit");

const { IOServiceMatching } = objc; // => Err

I think that the call to getResourceValue_forKey_error should be ok, but may of course be wrong. In that case, what should I change?

I want to get current NSView or NSWindow.
Is it possible?

how can i import custom framework ,for example test.framework?

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch [email protected] for the project I'm working on.

objc[cls][method](...args)

// xxxx.apply is not a function

Here is the diff that solved my problem:

I can extract the base address from a CVPixelBuffer using CVPixelBufferGetBaseAddress like this:

let baseAddress = c.CVPixelBufferGetBaseAddress(imageBuffer);

I also know the format, size, and width, and can lock down the base address.

I am having a mental block on getting the data out of the runtime so I can manipulate it in Node. Ideally, I'd like to get the pixel data into a Node Buffer object. I have a pointer now (baseAddress), how do I marshal the data over to Node?

Bravo for doing this. I'm jonesing to pass in a delegate that ends up as a callback/event in JS. I see you support blocks; is there a way to define a delegate?

The importFramework utility function throws an unhelpful error message when NSBundle.bundleWithPath_(path) returns null (e.g. because the path was invalid):

/Users/foo/node_modules/objc/src/util.js:25
  bundle.load();
TypeError: Cannot read properties of null (reading 'load')

I suggest inserting a null check before the bundle.load() line that throws a descriptive error:

  if (bundle === null) { throw Error(`Framework not found: '${path}'`); }

when install objc,
got an error:
[email protected]: The engine "node" is incompatible with this module. Expected version ">=8 <9". Got "10.13.0"

I am trying to port an app of mine to macOS, and since I need to use MediaRemote.framework which is private, I wondered if there's a way to use this project with that.

I just upgraded my Electron project that uses objc to version 4.0.0, which meant a Node upgrade to 10.11.0. In the process I also upgraded objc to 0.19.

And now I get the following error at runtime:

dyld: lazy symbol binding failed: Symbol not found: __ZN2v811HandleScope12CreateHandleEPNS_8internal10HeapObjectEPNS1_6ObjectE
  Referenced from: /Users/ejal/dev/filur/node_modules/ref/build/Release/binding.node
  Expected in: flat namespace

By commenting out the import of objc, the error goes away.

Any ideas?

Hi! I'm trying to find all scan devices using ImageCaptureCore, but the code below doesn't call the delegate's methods. And the similar Objective-C code does.
Maybe I'm wrong somewhere because header file(https://github.com/phracker/MacOSX-SDKs/blob/master/MacOSX10.7.sdk/System/Library/Frameworks/ImageCaptureCore.framework/Versions/A/Headers/ICDeviceBrowser.h) is slight different from your example with NSFileManager

const objc = require('../src/index');

const ICDeviceLocationTypeMaskLocal     = 0x00000100;
const ICDeviceLocationTypeMaskShared    = 0x00000200;
const ICDeviceLocationTypeMaskBonjour   = 0x00000400;
const ICDeviceLocationTypeMaskBluetooth = 0x00000800;
const ICDeviceLocationTypeMaskRemote    = 0x0000FE00;
const ICDeviceTypeMaskCamera            = 0x00000001;
const ICDeviceTypeMaskScanner           = 0x00000002;

objc.import('ImageCaptureCore');

const {
    ICDeviceBrowser
} = objc;

const DeviceBrowserDelegate = objc.createClass('DeviceBrowserDelegate', 'NSObject', {
    "deviceBrowser:didAddDevice:moreComing:": (self, cmd, fileManager, srcPath, dstPath) => {
        console.log("deviceBrowser:didAddDevice:moreComing:");
        return 1;
    },
    "deviceBrowser:didRemoveDevice:moreGoing:": (self, cmd, fileManager, srcPath, dstPath) => {
        console.log("deviceBrowser:didAddDevice:moreComing:");
        return 1;
    },
    _encodings: {
        "deviceBrowser:didAddDevice:moreComing:": ['v', ['@', ':', '@', '@', 'c']],
        "deviceBrowser:didRemoveDevice:moreGoing:": ['v', ['@', ':', '@', '@', 'c']]
    }
});

const deviceBrowser = ICDeviceBrowser.alloc().init();
const delegate = DeviceBrowserDelegate.new();
deviceBrowser.setDelegate_(delegate);


const mask = ICDeviceTypeMaskScanner | ICDeviceLocationTypeMaskLocal | ICDeviceLocationTypeMaskShared | ICDeviceLocationTypeMaskBonjour | ICDeviceLocationTypeMaskRemote;
deviceBrowser.setBrowsedDeviceTypeMask_(mask);


deviceBrowser.start();

setInterval(() => {
    console.log(deviceBrowser.isBrowsing());
}, 2000);

This is a follow-up question to my previous one, and again I'm not sure if it's a bug or I'm doing something wrong.

I'm trying to check that the errorOut variable is null in the following code:

    const trashedFileUrlOut = objc.allocRef();
    const errorOut = objc.allocRef();
    const fm = NSFileManager.defaultManager();
    const success = fm.trashItemAtURL_resultingItemURL_error_(
      nsFileUrl,
      trashedFileUrlOut,
      errorOut
    );

    // Fails because errorOut seems to be an empty object in JS
    expect(errorOut).toBeNull();

    // js function fails with 'Unable to find method isKindOfClass_ on object (null)'
    expect(objc.js(errorOut)).toBeNull();

But I seem to need some other way of converting a null NSError* into JS land.

I need to use dispatch queues in my app. It's not super clear to me whether I have the mapping of this call right.

Apple docs say the call looks like this:

dispatch_queue_t dispatch_queue_create(const char *label, dispatch_queue_attr_t attr);

After some amount of whack-a-mole, I arrived at this code which seems to not cause an exception:

const c = new ffi.Library(null, {
    'dispatch_queue_create': ['pointer', ['string', 'long']]
});

I call the function like this:

let queue = c.dispatch_queue_create('myQueue', 0);

But I am suspicious of defining the dispatch_queue_attr_t parameter as a 'long'.

What should it be?

First of all, big thanks for putting this library together. I was looking hard and long for something up-to-date for calling native Mac APIs and only discovered this through a comment hidden beneath a SO question.

I'm trying to use it to send an item to the Trash on MacOS via NSWorkspace.recycleURLs, but I'm not sure I've quite got the hang of how to pass arguments into Cocoa functions. The method is expecting an NSArray of NSURL objects, but whatever I do, the call fails with the error:

NSInvalidArgumentException -[__NSDictionaryM isFileURL]: unrecognized selector sent to instance 0x103c71d10

Since isFileURL is a method on NSURL, I draw the conclusion that Cocoa somehow gets a dictionary instead of an NSURL on which it tries to call isFileURL.

I've tried various different ways of creating the array, but no luck so far. Here is my code:

    objc.import("AppKit");

    const {
      NSWorkspace,
      NSURL,
      NSArray
    } = objc;

    const nsUrl = NSURL.fileURLWithPath_isDirectory_(
      objc.ns(filePath),
      false
    );

    // This logs what looks like an actual NSURL object
    log.log("nsUrl", nsUrl);

    const nsArray = [nsUrl];
    //const nsArray = objc.ns([nsUrl]);
    //const nsArray = NSArray.arrayWithArray_([nsUrl]);

    // This logs an empty array if I use either of the latter two lines above
    log.log("nsArray", nsArray);

    const workspace = NSWorkspace.sharedWorkspace();

    // Bam!
    workspace.recycleURLs_completionHandler_(nsArray, null);

What am I missing?

Although we can introspect various Obj-C symbols via the Obj-C runtime helpers e.g. objc_getClass, C functions, enums, and other symbols are not introspectable at runtime, as I found in #43 (you can see in the comments various symbol lookups that failed - NSTitledWindowMask is one of them).

I believe the root of the problem is that bundle.load(), used here:

... does not load any C symbols for the dynamic linker to find. Well, my reasoning may be wrong, but either way, they're not being found in this call (we're throwing an error):

I believe we'd have more success by adopting the approach used by NodObjc to look up symbols, which involves loading the BridgeSupport files, which were specifically designed for use by Objective-C bridges like RubyCocoa and PyObjC.

Alternatively, we may be able to get further on the back of the existing approach by importing Core Foundation and introducing calls to CFBundleGetDataPointerForName and CFBundleGetFunctionPointerForName, but this would turn things into an O(2N) lookup as more and more frameworks are imported (check the data pointer and then the function pointer for each framework we've imported during the app's lifespan), and unlike the BridgeSupport approach, it's not yet tried-and-tested.

Again, great package! This might just be a clarification, but as I'm trying to figure out why my delegate doesn't work, I'm noticing a few things I don't entirely understand that might help me figure it out.

I've created a custom class so I can register a delegate. I've used the FileManagerDelegate example as a template for my own.

Your readme mentions:

Note: You might have to specify individual offsets in the type encoding, see this example.

I'd love to know what you mean by this, and what it means for how I define my delegate.

For reference, I'm creating a delegate for AVCaptureVideoDataOutputSampleBufferDelegate. One thing I noted is the use of the term 'c40' for the return value of the FileManagerDelegate example, which is a bool. I assume this means bool and char are the same, but not sure what the 40 is for.

This may not be my problem, but it might be nice to have this be clearer in the docs.

const AVCaptureVideoDataOutputSampleBufferDelegate = objc.createClass(
    'AVCaptureVideoDataOutputSampleBufferDelegate',
    'NSObject',
    {
        'captureOutput:didOutputSampleBuffer:fromConnection:': (
            self,
            cmd,
            captureOutput,
            sampleBuffer,
            connection
        ) => {
            console.log(
                '-[AVCaptureVideoDataOutputSampleBufferDelegate captureOutput:didOutputSampleBuffer:fromConnection:]'
            );
            return 1;
        },

        _encodings: {
            'captureOutput:didOutputSampleBuffer:fromConnection:': [
                'v',
                ['@0', ':8', '@16', '@24', '@32']
            ]
        }
    }
);
