tree-sitter-objc

这个软件包为 tree-sitter 解析库提供 Objective-C 语法。要使用此软件包，将其添加到您的 [dependencies] 部分中。请注意，您可能还需要依赖 tree-sitter 软件包，以便以任何有用的方式使用解析结果。

[dependencies]
tree-sitter = "~0.20.10"
tree-sitter-objc = "3.0.0"

通常，您将使用 language 函数将此语法添加到 tree-sitter Parser，然后使用解析器解析一些代码

let code = r#"
#import <Foundation/Foundation.h>

// Defining a class interface
@interface Person : NSObject

// Declaring properties
@property (nonatomic, strong) NSString *name;
@property (nonatomic, assign) NSInteger age;

// Declaring methods
- (instancetype)initWithName:(NSString *)name age:(NSInteger)age;
- (void)greet;

@end

@implementation Person

// Implementing the initializer
- (instancetype)initWithName:(NSString *)name age:(NSInteger)age {
    self = [super init];
    if (self) {
        _name = name;
        _age = age;
    }
    return self;
}

// Implementing the greet method
- (void)greet {
    NSLog(@"Hello, my name is %@ and I'm %ld years old.", self.name, (long)self.age);
}

@end

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        // Creating an instance of Person
        Person *person = [[Person alloc] initWithName:@"John" age:25];

        // Accessing properties
        NSString *name = person.name;
        NSInteger age = person.age;

        // Calling a method
        [person greet];
    }
    return 0;
