# Context:
USER: add a --show-diffs parameter which defaults to false. allow an env var to override the default. pass this to Coder.__init__() and use it to set a self.show_diffs. only self.console.print(Text(diffs)) if it is true.
ASSISTANT: To add a `--show-diffs` parameter with a default value of `False` and allow an environment variable to override the default, we will make changes to `aider/main.py`. We will also pass this value to `Coder.__init__()` and use it to set `self.show_diffs`. Finally, we will only print the diffs if `self.show_diffs` is `True`.
Here are the changes:
```python
aider/main.py
<<<<<<< ORIGINAL
default=bool(int(os.environ.get(f"{env_prefix}COMMIT_DIRTY", 0))),
)
args = parser.parse_args()
=======
default=bool(int(os.environ.get(f"{env_prefix}COMMIT_DIRTY", 0))),
)
parser.add_argument(
"--show-diffs",
action="store_true",
help=f"Show diffs when committing changes (default: False, ${env_prefix}SHOW_DIFFS)",
default=bool(int(os.environ.get(f"{env_prefix}SHOW_DIFFS", 0))),
)
args = parser.parse_args()
>>>>>>> UPDATED
```
```python
aider/main.py
<<<<<<< ORIGINAL
coder = Coder(args.model, fnames, pretty, args.history_file)
=======
coder = Coder(args.model, fnames, pretty, args.history_file, args.show_diffs)
>>>>>>> UPDATED
```
```python
aider/coder.py
<<<<<<< ORIGINAL
def __init__(self, main_model, files, pretty, history_file):
=======
def __init__(self, main_model, files, pretty, history_file, show_diffs):
>>>>>>> UPDATED
```
```python
aider/coder.py
<<<<<<< ORIGINAL
self.pretty = pretty
=======
self.pretty = pretty
self.show_diffs = show_diffs
>>>>>>> UPDATED
```
```python
aider/coder.py
<<<<<<< ORIGINAL
self.console.print(Text(diffs))
=======
if self.show_diffs:
self.console.print(Text(diffs))
>>>>>>> UPDATED
```
These changes will add the `--show-diffs` parameter and only print the diffs if the parameter is set to `True`.
# Context:
USER: unroll the list comprehension so we can try/catch the exception below which is thrown for files not in any git repo
File "/Users/gauthier/Projects/aider/aider/coder.py", line 68, in <genexpr>
git.Repo(fname, search_parent_directories=True).git_dir
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/Users/gauthier/tmp/try-aider/.venv/lib/python3.11/site-packages/git/repo/base.py", line 265, in __init__
raise InvalidGitRepositoryError(epath)
git.exc.InvalidGitRepositoryError: /Users/gauthier/tmp/try-aider/tmp.py
ASSISTANT: To unroll the list comprehension and handle the exception, we can replace it with a for loop and use try-except to catch the `InvalidGitRepositoryError`.
```python
aider/coder.py
<<<<<<< ORIGINAL
repo_paths = list(
git.Repo(fname, search_parent_directories=True).git_dir
for fname in self.fnames
)
=======
repo_paths = []
for fname in self.fnames:
try:
repo_path = git.Repo(fname, search_parent_directories=True).git_dir
repo_paths.append(repo_path)
except git.exc.InvalidGitRepositoryError:
pass
>>>>>>> UPDATED
```
This change will catch the `InvalidGitRepositoryError` and continue processing the remaining files.
