**Explanation:**
1. **`#!/bin/bash`**: Shebang line, specifying the script should be executed with Bash.
2. **`set -e`**: This crucial line ensures that the script exits immediately if any command fails. This prevents unexpected behavior and makes debugging easier.
3. **`git add -A`**: Stages all changes in the repository for commit.
4. **`FILES=$(git diff --cached --name-only)`**: This line retrieves a list of staged files from the Git index. `--cached` ensures it only includes staged files, and `--name-only` provides just the filenames.
5. **`if [ -z "$FILES" ]; then ... fi`**: Checks if any files are staged. If not, it prints a message and exits gracefully. This avoids errors when there's nothing to commit.
6. **`for FILE in $FILES; do ... done`**: Iterates through each staged file.
7. **`DIFF=$(git diff --cached -- "$FILE")`**: Gets the diff content of the current file. `--cached` ensures it's the staged diff.
8. **`if [ -z "$DIFF" ]; then continue; fi`**: Checks if there's a diff for the current file. If not (meaning the file hasn't changed), it skips to the next file.
9. **`MSG=$(echo "$DIFF" | ollama run gemma3 ...)`**: This is the core of the script. It pipes the diff content to Ollama to generate a commit message.
* `ollama run gemma3`: Executes the `gemma3` model in Ollama.
* `"You are a commit bot. Write a clear, concise Git commit message for changes in file: $FILE. Only output the commit message, nothing else. Diff: $DIFF"`: The prompt given to the Ollama model. It clearly instructs the model to create a concise commit message based on the file and its diff content.
* The `gemma3` model is used, likely a smaller and faster model.
10. **`git commit -m "$MSG" -- "$FILE"`**: Commits the file with the generated message.
* `-m "$MSG"`: Specifies the commit message.
* `-- "$FILE"`: Indicates that only this file should be committed.
11. **`echo "✅ Committed $FILE with message:"` and `echo "$MSG"`**: Prints confirmation messages, making the script user-friendly.
**Potential Improvements:**
* **Error Handling within the Loop:** The script should handle potential errors during the `git commit` command within the loop. If a commit fails for one file, it should continue to process the remaining files. You can add `|| exit 1` after the `git commit` command to achieve this.
* **Ollama Model Configuration:** Consider making the Ollama model name (`gemma3`) configurable via a variable. This would allow users to easily switch models.
* **More Robust Diff Parsing:** The script assumes the diff content is simple. If the diff is complex (e.g., contains whitespace issues), it might not generate the desired commit message. A more robust solution would involve parsing the diff more carefully.
* **Logging:** Add more detailed logging to help with debugging.
* **Confirmation Prompt:** Before committing each file, you could ask the user for confirmation (e.g., "Do you want to commit $FILE with message $MSG?").
* **Interactive Diff Viewer:** For more complex changes, using a tool that allows the user to view the diff interactively and then provide the commit message could be beneficial.
**Example with Error Handling and Logging:**
```bash
#!/bin/bash
set -e
# Configuration
OLLAMA_MODEL="gemma3"
# 1. Stage everything
git add -A
# 2. Get list of staged files
FILES=$(git diff --cached --name-only)
if [ -z "$FILES" ]; then
echo "No changes to commit."
exit 0
fi
for FILE in $FILES; do
# Get diff for this file
DIFF=$(git diff --cached -- "$FILE")
if [ -z "$DIFF" ]; then
continue
fi
# Ask Ollama for a commit message describing this file change
MSG=$(echo "$DIFF" | ollama run "$OLLAMA_MODEL" \
"You are a commit bot. Write a clear, concise Git commit message for changes in file: $FILE.
Only output the commit message, nothing else.
Diff:
$DIFF")
# Commit just this file with its message
echo "Committing $FILE with message: $MSG"
git commit -m "$MSG" -- "$FILE" || {
echo "Error committing $FILE. Continuing..."
# Handle the error more gracefully here if needed
}
echo "✅ Committed $FILE with message:"
echo "$MSG"
done
```
This revised script is more robust and provides better error handling. It's a solid foundation for an automated commit script. Remember to install Ollama and the `gemma3` model before running the script.
