Verified usage

Verified import paths — ran on the pinned version, not inferred.

Language

✓ from tree_sitter_objc import language

✗ from tree_sitter_objc import Language

The correct import is the function 'language', not a class 'Language' directly.

Minimal example: load the grammar, parse ObjC code, and print the syntax tree.

from tree_sitter import Language, Parser # Load the Objective-C grammar (v3.0.2) ObjCLanguage = Language('tree_sitter_objc', 'objc') parser = Parser() parser.set_language(ObjCLanguage) # Parse a simple Objective-C snippet source = b""" #import <Foundation/Foundation.h> @interface MyClass : NSObject - (void)sayHello; @end """ tree = parser.parse(source) print(tree.root_node.sexp())

Debug

Known issues

breakingv3.0.0+ switched from a direct 'Language' class to a 'language()' function. The grammar is loaded via tree-sitter's Language constructor using the module name.

fix

Use 'from tree_sitter_objc import language' and pass it to Language() or use Language('tree_sitter_objc', 'objc').

affects: >=3.0.0

gotchaThe grammar module name is 'tree_sitter_objc' but the language name is 'objc'. Do not confuse these.

fix

When using Language('tree_sitter_objc', 'objc'), the second argument is the language name, not the module name.

affects: all

deprecatedPython 3.8 and earlier are not supported. Requires Python >=3.9.

fix

Upgrade Python to 3.9 or later.

affects: >=3.0.0

Errors

Common errors & fixes

ImportError: cannot import name 'Language' from 'tree_sitter_objc'

Incorrect import: trying to import a class 'Language' that does not exist.

fix

Use 'from tree_sitter_objc import language' or 'from tree_sitter import Language'.

AttributeError: module 'tree_sitter_objc' has no attribute 'language'

Outdated version of tree-sitter-objc (before v3.0.0) or the grammar wasn't properly installed.

fix

Install the latest version: pip install --upgrade tree-sitter-objc.

ValueError: Unknown language 'objc'

The language name passed to Language() doesn't match the registered grammar.

fix

Use 'objc' (not 'objective-c' or 'objc++') for the language name.
