USER: improve the para starting "Of course for large repos"
ASSISTANT: ```markdown
docs/ctags.md
<<<<<<< ORIGINAL
Of course, for large repos even their map might be too large for
the context window.
But this mapping approach enables
collaboration with GPT-4 on larger code bases
than was previously possible.
And it reduces the need to manually curate which files to add
to the chat, giving GPT itself more ability to identify which files
are relevant to the task at hand.
=======
Of course, for large repositories, even their map might be too large for the context window. However, this mapping approach significantly improves collaboration with GPT-4 on larger codebases compared to previous methods. It also minimizes the need for manual curation of files to add to the chat, empowering GPT to autonomously identify relevant files for the task at hand.

# Context:
USER: make -v short for --verbose
ASSISTANT: To make `-v` a short option for `--verbose`, you can modify the `aider/main.py` file. Here's the change:
```python

"--verbose",
action="store_true",
help="Enable verbose output",

# Context:
USER: Add --verbose with no env default. pass into Coder and set self.verbose
ASSISTANT: To add the `--verbose` option, we need to modify the `aider/main.py` file. Here's the step-by-step process:
1. Add the `--verbose` argument to the `argparse.ArgumentParser` in the `main` function.
2. Pass the `args.verbose` value to the `Coder` class when initializing it.
3. Update the `Coder` class in the `aider/coder.py` file to accept the `verbose` parameter and set `self.verbose`.
Here are the changes to the code:
```python

# Context:
USER: `Coder.get_commit_message()` uses gpt-3.5-turbo to summarize the diffs into a sensible commit message. If the diff is large, it exceeds the 4K context window.
A simple fix would be:
1. Check if the diff is close to or larger than 4 kbytes (4k tokens * 4 bytes/token) and don't even bother sending the messages to gpt. Just return.
2. Catch the `openai.error.InvalidRequestError` and just return.
Maybe print a nice tool_error() message for each of these.
ASSISTANT: To implement the suggested changes, we will modify the `get_commit_message()` method in the `aider/coder.py` file. Here are the step-by-step changes:
1. Check if the length of `diffs` is close to or larger than 4 kbytes (4k tokens * 4 bytes/token). If it is, print an error message and return.
2. Catch the `openai.error.InvalidRequestError` exception when calling `self.send()` and print an error message, then return.
Here are the code changes:
```python

def get_commit_message(self, diffs, context):
diffs = "# Diffs:\n" + diffs

# Context:
USER: add an in memory cache to get_tags that only updates if the st_mtime of the filename changes
ASSISTANT: To implement an in-memory cache for the `get_tags` function, we will need to modify the `aider/ctags.py` file. We will use a dictionary to store the cache and check the file's modification time to decide whether to update the cache or not.
Here are the steps to implement the cache:
1. Create a global variable `TAGS_CACHE` to store the cache.
2. In the `get_tags` function, check if the filename is in the cache and if the modification time has not changed.
3. If the conditions in step 2 are met, return the cached value.
4. If the conditions in step 2 are not met, update the cache with the new tags and return them.

ASSISTANT: To add the test for `cmd_add`, we will modify the `tests/test_commands.py` file. Here's the step-by-step plan:
1. Import the necessary libraries and classes.
2. Create a new test method called `test_cmd_add` inside the `TestCommands` class.
3. In the `test_cmd_add` method, create a temporary directory using `tempfile.TemporaryDirectory`.
4. Change the current working directory to the temporary directory.
5. Create an instance of the `InputOutput` and `Coder` classes.
6. Create an instance of the `Commands` class, passing the `InputOutput` and `Coder` instances.
7. Call the `cmd_add` method with the arguments `['foo.txt', 'bar.txt']`.
8. Check if both 'foo.txt' and 'bar.txt' files have been created in the temporary directory.
9. Change the current working directory back to the original directory.
Here's the code change:
```python
tests/test_commands.py
<<<<<<< ORIGINAL
=======
import os
import tempfile
from unittest import TestCase
from aider.io import InputOutput
from aider.coder import Coder
from aider.commands import Commands
class TestCommands(TestCase):
def test_cmd_add(self):

original_cwd = os.getcwd()
os.chdir(tmpdir)
io = InputOutput()
coder = Coder(io)
commands = Commands(io, coder)
commands.cmd_add(['foo.txt', 'bar.txt'])
self.assertTrue(os.path.exists('foo.txt'))
self.assertTrue(os.path.exists('bar.txt'))
os.chdir(original_cwd)
>>>>>>> UPDATED
```
This will add the test for `cmd_add` and ensure that both 'foo.txt' and 'bar.txt' have been created after the test.
