This crate provides an Objective-C grammar for the tree-sitter parsing library. To
use this crate, add it to the [dependencies]
section of your Cargo.toml
file. (Note that you will probably also need to depend on the
tree-sitter
crate to use the parsed result in any useful
way.)

[dependencies]
tree-sitter = "~0.20.10"
tree-sitter-objc = "3.0.0"
Typically, you will use the language function to add this grammar to a tree-sitter Parser, and then use the parser to parse some code:
```rust let code = r#"
// 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;
} "#; let mut parser = Parser::new(); parser.setlanguage(treesitter_objc::language()).expect("Error loading Objective-C grammar"); let parsed = parser.parse(code, None); ```
