# 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

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!
