ASSISTANT: Great! Now, please let me know what changes you would like to make in the `aider/repomap.py` file.
USER:   File "/Users/gauthier/Projects/aider/aider/repomap.py", line 318, in get_ranked_tags_map
    tree = to_tree(ranked_tags[:middle])
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

IndexError: list index out of range
ASSISTANT: It seems like you are encountering an IndexError due to an empty `tags` list. To fix this issue, you can add a check to ensure that the `tags` list is not empty before accessing its elements. Here's the change you need to make in the `aider/repomap.py` file:

```python
aider/repomap.py
<<<<<<< ORIGINAL
def to_tree(tags):
    tags = sorted(tags)

    output = ""
    last = [None] * len(tags[0])
=======
def to_tree(tags):
    if not tags:
        return ""

    tags = sorted(tags)

    output = ""
    last = [None] * len(tags[0])
>>>>>>> UPDATED
```

This change adds a check for an empty `tags` list and returns an empty string if the list is empty, preventing the IndexError.
