4. Step-by-Step Guides, Tutorials, and Examples

Using Ollama for Commit Message Generation

Step 1: Install Ollama

Ollama is available as an open-source project and can be installed using various methods, including:

• Docker: The simplest approach is to run Ollama using a Docker container.
• Local Installation: Ollama can also be installed locally using Python and pip.

Step 2: Run Ollama and access its conversational interface.

Step 3: Interact with Ollama using text prompts.

To generate a commit message, provide Ollama with relevant information:

• Code Changes: Include the modified files, lines of code affected, and the nature of the changes.
• Context: Describe the overall purpose of the changes and any relevant context.
• Desired Style: Specify the desired tone and style of the commit message.

Example Prompt:

>  "I have modified the 'utils.py' file, added a new function to calculate the average of a list, and updated the main function to use this new function. Please generate a concise and informative commit message."

Ollama will analyze the provided context and code changes and generate a suitable commit message:

> "Add function to calculate average of a list and update main function." 

Using Kaizen for Commit Message Generation

Step 1: Install Kaizen.

Kaizen can be installed as a command-line tool using package managers like npm or pip:

pip install kaizen

Step 2: Configure Kaizen.

Kaizen allows customization of message templates and integration with version control systems.

Step 3: Generate commit messages.

Kaizen can be used directly from the command line:

kaizen -d
<directory>

Where
<directory>
refers to the directory containing the modified files. Kaizen analyzes the code changes and generates a commit message based on its analysis.

Example:

kaizen -d my_project

Kaizen analyzes the changes in the my_project directory and generates a commit message like:

> "Fix: Updated function to handle null values"

5. Challenges and Limitations

Challenges:

• Contextual Understanding: Ollama and Kaizen rely on natural language processing to understand code changes and generate meaningful messages. There might be cases where they struggle to grasp complex code logic or nuanced contexts.
