उद्देश्य-सी कोड से एएसटी निकालने के लिए कैसे?

Question

मैं संभव उपकरणों मुझे पता चला कि LLVM से बजना उपकरण एएसटी डंप कर सकते हैं में देखने के बाद ऑब्जेक्टिव-सी स्थिर कोड, मुख्य रूप से एएसटी, विश्लेषण करने की जरूरत है, इसलिए मैं इस आदेश का उपयोग कर यह परीक्षण करने के लिए टर्मिनल का उपयोग किया:

clang -cc1 -ast-dump ~/SomeTest.m

किसी भी विचार मैं ऐसा क्यों हो रही है:

लेकिन मैं इस त्रुटि हो रही है? जब तक यह विश्वसनीय नहीं है और आउटपुट

Answer 1

के लिए प्रलेखन प्रदान करने के लिए किसी भी उपकरण का उपयोग करने से कोई फर्क नहीं पड़ता है, तो कंपाइलर को UIKit ढांचे नहीं मिलते हैं।

clang -framework UIKit -cc1 -ast-dump ~/SomeTest.m 

Answer 2

-Xclang -ast-dump बजाय -cc1 -ast-dump प्रयास करें: आप इसे उपयोग करने के लिए यह बताने के लिए है। (मानक अस्वीकरण: कुछ भी -Xclang या -cc1 का उपयोग कर संकलक करने के लिए एक अस्थिर इंटरफ़ेस का उपयोग कर रहा है।)

Answer 3

ओपी कहते मैं ऑब्जेक्टिव-सी कोड से एएसटी को निकालने के लिए किसी भी उपकरण का उपयोग कर कोई आपत्ति नहीं है ...

हमारा DMS Software Reengingineering Toolkit उद्देश्य-सी के लिए ऐसा कर सकता है।

डीएमएस उत्पन्न पार्सर "domainparser" करने के लिए इस कमांड लाइन के लिए:

run \DMS\Domains\C\ObjectiveCv2\Tools\Parser\domainparser ++AST "C:\temp\test.m" 

इस उद्देश्य सी फ़ाइल "test.m":

@implementation GTLClientLoginAuthorizationArgs 

@synthesize request = request_, 
    delegate = delegate_, 
    selector = sel_, 
    completionHandler = completionHandler_, 
    thread = thread_, 
    error = error_; 

+ (GTLClientLoginAuthorizationArgs *)argsWithRequest:(NSMutableURLRequest *)req 
        delegate:(id)delegate 
        selector:(SEL)sel 
       completionHandler:(id)completionHandler 
         thread:(NSThread *)thread { 
    GTLClientLoginAuthorizationArgs *obj; 
    obj = [[[GTLClientLoginAuthorizationArgs alloc] init] autorelease]; 
    obj.request = req; 
    obj.delegate = delegate; 
    obj.selector = sel; 
    obj.completionHandler = completionHandler; 
    obj.thread = thread; 
    return obj; 
} 

- (void)dealloc { 
    self.request = nil; 
    self.delegate = nil; 
    self.selector = NULL; 
    self.completionHandler = nil; 
    self.thread = nil; 
    self.error = nil; 
    [super dealloc]; 
}

यह एक लोकप्रिय पुस्तकालय से लिया गया एक कोड खंड है; यह सिर्फ एक टुकड़ा है क्योंकि अन्यथा पेड़ बहुत बड़ा होगा। मैंने #imports को छोड़कर, एक छोटा सा भी धोखा दिया, जो मुझे आसानी से कॉन्फ़िगर किया गया पार्सर चलाने देता है। डीएमएस # अंतर्निहित फाइलों को पार्स करेगा और निर्देश बनाए रखेगा या शामिल पाठ को बनाए रखेगा, इस पर निर्भर करता है कि इसका पार्सर कैसे कॉन्फ़िगर किया गया है।

यह ObjectiveC के लिए है, ObjectiveC++ नहीं। हम उस पर काम कर रहे हैं: -}

डीएमएस प्रोग्राम विश्लेषण के लिए बहुत अधिक समर्थन प्रदान करता है जो इसे उत्पन्न एएसटी पर संचालित करता है।
