[WARNING] Stashed changes conflicted with hook auto-fixes... Rolling back fixes...
[INFO] Restored changes from /Users/gauthier/.cache/pre-commit/patch1715981257-12950.
ASSISTANT: Please add `aider/linter.py` to the chat so I can make the necessary changes to fix the issues reported by the pre-commit hooks.
USER: I added these files to the chat: aider/linter.py
ASSISTANT: To fix the issues reported by the pre-commit hooks, we need to:
1. Remove unused imports: `os`, `tree_sitter`, and `dump`.
2. Remove the unused variable `language`.
Here are the *SEARCH/REPLACE* blocks:
aider/linter.py
```python
<<<<<<< SEARCH
import os
import sys
import warnings
from pathlib import Path
import tree_sitter
from grep_ast import TreeContext, filename_to_lang
from aider.dump import dump
=======
import sys
import warnings
from pathlib import Path
from grep_ast import TreeContext, filename_to_lang
>>>>>>> REPLACE
```
aider/linter.py
```python
<<<<<<< SEARCH
language = get_language(lang)
=======
>>>>>>> REPLACE
```
Now, the file should pass the pre-commit hooks.
# Aider chat conversation:
USER: print out the line and the N=3 lines before/after it
ASSISTANT: To print out the line with the error and the 3 lines before and after it, we need to modify the `traverse_tree` function in `aider/linter.py`. Here are the necessary changes:
aider/linter.py
```python
<<<<<<< SEARCH
# Traverse the tree to find errors
=======
# Traverse the tree to find errors and print context
>>>>>>> REPLACE
```
aider/linter.py
```python
<<<<<<< SEARCH
print(f"{error_type} at line: {node.start_point[0] + 1}")
=======
start_line = max(0, node.start_point[0] - 3)
end_line = node.end_point[0] + 3
error_line = node.start_point[0] + 1
with open(file_path, 'r') as file:
lines = file.readlines()
print(f"{error_type} at line: {error_line}")
print("Context:")
for i in range(start_line, min(end_line, len(lines))):
line_number = i + 1
prefix = ">> " if line_number == error_line else " "
print(f"{prefix}{line_number}: {lines[i].rstrip()}")
print("\n")
>>>>>>> REPLACE
```
This will ensure that the linter prints the error type, the line number, and the context of 3 lines before and after the error.
# Aider chat conversation:
USER: is node.type 'ERROR" a standard across all tree sitter languages?
ASSISTANT: The `node.type == 'ERROR'` check is specific to the Tree-sitter library and is used to identify syntax errors in the parsed code. This is a standard feature across all languages supported by Tree-sitter.
Would you like to proceed with any changes or enhancements to the `aider/linter.py` file? If so, please specify the changes you need.
USER: is MISSING ever used to indicate a parsing/syntax problem
ASSISTANT: Yes, in Tree-sitter, `MISSING` is also used to indicate a parsing or syntax problem. Specifically, it indicates that a required element is missing in the syntax tree.
Would you like to update the `aider/linter.py` file to also check for `MISSING` nodes? If so, I can provide the necessary changes.
USER: yes
ASSISTANT: To update the `aider/linter.py` file to also check for `MISSING` nodes, we need to modify the `traverse_tree` function. Here are the necessary changes:
aider/linter.py
```python
<<<<<<< SEARCH
if node.type == 'ERROR':
print(f"Syntax error at line: {node.start_point[0] + 1}")
=======
if node.type == 'ERROR' or node.is_missing:
error_type = 'Syntax error' if node.type == 'ERROR' else 'Missing element'
print(f"{error_type} at line: {node.start_point[0] + 1}")
>>>>>>> REPLACE
```
This change will ensure that the linter checks for both `ERROR` and `MISSING` nodes and reports them accordingly.
# 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')`.
# Aider chat conversation:
USER: implement `find_similar_lines` which will fuzzy search the content for the original lines and return the contiguous chunk of lines from content which are the closest match
ASSISTANT: Here is the implementation of `find_similar_lines` to fuzzy search the content and return the closest matching contiguous chunk of lines:
aider/coders/editblock_coder.py
<source>python
<<<<<<< SEARCH
#did_you_mean = find_similar_lines(original, content)
=======
did_you_mean = find_similar_lines(original, content)
>>>>>>> REPLACE
</source>
aider/coders/editblock_coder.py
<source>python
<<<<<<< SEARCH
=======
def find_similar_lines(search_lines, content_lines, threshold=0.8):
search_lines = search_lines.splitlines()
content_lines = content_lines.splitlines()
best_ratio = 0
best_match = None
for i in range(len(content_lines) - len(search_lines) + 1):
chunk = content_lines[i:i+len(search_lines)]
ratio = SequenceMatcher(None, search_lines, chunk).ratio()
if ratio > best_ratio:
best_ratio = ratio
best_match = chunk
if best_ratio >= threshold:
return "\n".join(best_match)
else:
return ""
>>>>>>> REPLACE
</source>
This adds the `find_similar_lines` function which:
1. Splits the search lines and content lines on newlines
2. Iterates through the content lines, considering each contiguous chunk the same length as the search lines
3. Calculates the SequenceMatcher ratio between the search lines and each chunk
4. Keeps track of the chunk with the highest ratio
5. If the best ratio is above the threshold (default 0.8), it returns the best matching chunk joined back into a string
6. Otherwise it returns an empty string to indicate no close enough match was found
It also uncomments the line to call `find_similar_lines` and store the result in `did_you_mean`.
Let me know if you have any other questions!
# Aider chat conversation:
USER: I did `git reset --hard HEAD~1` to discard the last edits. Please wait for further instructions before attempting that change again. Feel free to ask relevant questions about why the changes were reverted.
ASSISTANT: I understand you reverted the previous changes. Before I attempt to implement the `find_similar_lines` function again, I have a few questions to ensure I follow your guidelines correctly:
1. When proposing changes, should I only modify the `aider/coders/editblock_coder.py` file since that is the only one you have explicitly added to the chat
^C KeyboardInterrupt
USER: implement `find_similar_text` which will fuzzy search the content for the original text and return the part of content which is the closest match
ASSISTANT: Here is the implementation of `find_similar_text` to fuzzy search the content for the closest match to the original text:
aider/coders/editblock_coder.py
<source>python
<<<<<<< SEARCH
=======
from difflib import SequenceMatcher
def find_similar_text(original, content):
content_len = len(content)
original_len = len(original)
best_ratio = 0
best_match = None
for i in range(content_len - original_len + 1):
chunk = content[i:i+original_len]
ratio = SequenceMatcher(None, original, chunk).ratio()
if ratio > best_ratio:
best_ratio = ratio
best_match = chunk
return best_match
>>>>>>> REPLACE
</source>
This function:
1. Iterates through the content, considering each chunk of text the same length as the original
2. Calculates the SequenceMatcher ratio between the original text and each chunk
3. Keeps track of the chunk with the highest ratio
4. Returns the chunk of content that best matches the original text
It will return the portion of `content` that is the closest fuzzy match to `original`.
Let me know if you have any other questions!
