# Context:
USER: in `replace_part_with_missing_leading_whitespace`, we want to find the string part in whole and replace it with the string `replace`. but `part` may not exactly occur in whole. instead, every line of part appears in whole with a fixed amount of extra whitespace in front of it. so every line in part might appear in whole with 4 spaces prepended. or every line might have 2 tabs. always the exact same whitespaces. finish implementing this function so that it finds the portion of whole which matches part in this manner (if any) and replace it with `replace` where replace is updated to contain that repeated/omitted whitespace.
ASSISTANT: To implement the `replace_part_with_missing_leading_whitespace` function, follow these steps:
1. Split `whole` and `part` into lines.
2. Iterate through the lines of `whole` and find the first line that matches the first line of `part` with any leading whitespace.
3. Check if the following lines in `whole` also match the remaining lines in `part` with the same leading whitespace.
4. If all lines match, replace the matched lines in `whole` with the lines in `replace` with the same leading whitespace.
5. Return the modified `whole` or `None` if no match is found.
Here's the updated function:
```python
aider/utils.py
<<<<<<< ORIGINAL
def replace_part_with_missing_leading_whitespace(whole, part, replace):
pass
=======
def replace_part_with_missing_leading_whitespace(whole, part, replace):
whole_lines = whole.splitlines()
part_lines = part.splitlines()
replace_lines = replace.splitlines()
for i in range(len(whole_lines) - len(part_lines) + 1):
leading_whitespace = ""
for j, c in enumerate(whole_lines[i]):
if c == part_lines[0][0]:
leading_whitespace = whole_lines[i][:j]
break
if not leading_whitespace:
continue
matched = all(
whole_lines[i + k].startswith(leading_whitespace + part_lines[k])
for k in range(len(part_lines))
)
if matched:
for k in range(len(part_lines)):
whole_lines[i + k] = leading_whitespace + replace_lines[k]
return "\n".join(whole_lines)
return None
>>>>>>> UPDATED
```
This implementation should find the portion of `whole` that matches `part` with the same leading whitespace and replace it with `replace` containing the same leading whitespace.
# Context:
USER: expand the context diff to 5 lines of context
ASSISTANT: To expand the context diff to 5 lines of context, you need to modify the `diff_partial_update` function in the `aider/diffs.py` file. Update the `unified_diff` function call to include the `n` parameter with a value of 5.
Here's the change:
```python
aider/diffs.py
<<<<<<< ORIGINAL
diff = difflib.unified_diff(lines_orig, lines_updated)
=======
diff = difflib.unified_diff(lines_orig, lines_updated, n=5)
>>>>>>> UPDATED
```
# Context:
USER: read 2 files named on the cmd line, use difflib to print their differences
ASSISTANT: To achieve this, we'll create a new Python script that reads two file names from the command line, reads the contents of the files, and then uses the `difflib` module to print their differences.
1. Create a new Python script called `diff_files.py` in the `aider` directory.
2. Import the necessary modules: `sys` and `difflib`.
3. Read the file names from the command line arguments.
4. Read the contents of the files.
5. Use `difflib.unified_diff()` to generate the differences.
6. Print the differences.
Here's the code for the new `diff_files.py` script:
```python
aider/diff_files
^C KeyboardInterrupt
USER: put it in `aider/diffs.py`
# Context:
USER: is there a standard way to version these cache files?
ASSISTANT: Yes, a standard way to version cache files is to include a version number in the cache file name or within the cache data. This allows you to easily identify and manage different versions of the cache, and update the cache handling logic when needed.
Here's how you can implement cache versioning in your `RepoMap` class:
1. Add a constant for the cache version at the beginning of the class.
2. Modify the cache directory names to include the version number.
3. When loading the cache, check if the version matches the current version. If not, clear the cache and start fresh.
Here are the changes you need to make in `aider/repomap.py`:
```python
aider/repomap.py
<<<<<<< ORIGINAL
class RepoMap:
ctags_cmd = ["ctags", "--fields=+S", "--extras=-F", "--output-format=json"]
IDENT_CACHE_DIR = ".aider.ident.cache"
TAGS_CACHE_DIR = ".aider.tags.cache"
=======
class RepoMap:
CACHE_VERSION = 1
ctags_cmd = ["ctags", "--fields=+S", "--extras=-F", "--output-format=json"]
IDENT_CACHE_DIR = f".aider.ident.cache.v{CACHE_VERSION}"
TAGS_CACHE_DIR = f".aider.tags.cache.v{CACHE_VERSION}"
>>>>>>> UPDATED
```
Now, whenever you need to change the cache format or handling logic, you can simply increment the `CACHE_VERSION` constant, and the cache will be automatically invalidated and recreated with the new version.
