# Aider chat conversation:
USER: write me a function that takes a file path and uses tree-sitter to parse the AST and print out the line number of every syntax/parse error in the file
ASSISTANT: To implement the function that takes a file path, uses tree-sitter to parse the AST, and prints out the line number of every syntax/parse error in the file, we need to:
1. Install the `tree-sitter` library.
2. Write the function in `aider/linter.py`.
Here is the *SEARCH/REPLACE* block for `aider/linter.py`:
aider/linter.py
```python
<<<<<<< SEARCH
=======
import os
import tree_sitter
def parse_file_for_errors(file_path):
"""
Parses the given file using tree-sitter and prints out the line number of every syntax/parse error.
"""
# Load the language
Language = tree_sitter.Language
PARSER = tree_sitter.Parser()
LANGUAGE = Language(os.path.join('build', 'my-languages.so'), 'python')
PARSER.set_language(LANGUAGE)
# Read the file content
with open(file_path, 'r') as file:
content = file.read()
# Parse the content
tree = PARSER.parse(bytes(content, "utf8"))
# Traverse the tree to find errors
def traverse_tree(node):
if node.type == 'ERROR':
print(f"Syntax error at line: {node.start_point[0] + 1}")
for child in node.children:
traverse_tree(child)
traverse_tree(tree.root_node)
>>>>>>> REPLACE
```
This code will:
1. Load the `tree-sitter` library and set up the parser for Python.
2. Read the content of the file specified by `file_path`.
3. Parse the content and traverse the AST to find and print the line numbers of any syntax errors.
You can now run this function by calling `parse_file_for_errors('path/to/your/file.py')`.
