I'm trying to add a custom declaration to my def file to help aid cinterops with a mocking library for iOS. The method is as follows

_Nullable id verify(id mock) {
     return  MKTVerifyWithLocation(mock, self, __FILE__, __LINE__);
}

cinterops throws error: use of undeclared identifier 'self'. Is cinterops not able to handle the self keyword yet or is there another way I should be handling this?

Did you mention that language is Objective-C in your . def file?

[drofwarcs]

Yes

[drofwarcs]

Full file:

language = Objective-C
headers = OCMockitoIOS.h
compilerOpts = -framework OCMockitoIOS
linkerOpts = -framework OCMockitoIOS

---
#import "MKTOngoingStubbing.h"
#import "NSInvocation+OCMockito.h"
#import "MKTMockitoCore.h"

MKTOngoingStubbing* given2(id testCase, id methodCall) {
    return [[MKTMockitoCore sharedCore] stubAtLocation:MKTTestLocationMake(testCase, __FILE__, __LINE__)];
}

_Nullable id verify2(id mock) {
     return  MKTVerifyWithLocation(mock, self, __FILE__, __LINE__);
}

Can this program be compiled by clang compiler?

[drofwarcs]

Haven't tried, but I believe it should be. Essentially, Im just trying to expose the following #define to kotlin
https://github.com/jonreid/OCMockito/blob/master/Source/OCMockito/Core/OCMockito.h#L216

[drofwarcs]

I worked around it by going a level deeper into the code and implementing passing in the class itself, but was still curious about cinterops giving an error on self.

[olonho]

There shall be no difference to what clang does, if program is legit objective-c - it shall compile. And here it seems there’s no class context for self to exist.

[drofwarcs]

Ahhh, gotcha.

Why do you expect self available not in an Objective-C method?

[drofwarcs]

I took that to mean that self is not available at the time cinterops does its conversion.

[svyatoslav.scherbina]

self is not available in simple top level functions in Objective-C. It is available only in Objective-C methods.

Thanks for the clarification 👍
