Commit Description as a Thinking Tool
TL;DR
Long commit descriptions serve as a valuable tool for software engineers, enhancing understanding and reflection on code changes. This practice not only documents changes but also clarifies the reasoning behind them.
✦ Why It Matters
Start writing detailed commit messages to enhance clarity and future code understanding.
Key Takeaways
- Dedicate time to write detailed commit messages.
- Include both the 'what' and 'why' in your descriptions.
- Use first-person language for clarity and relatability.
- Revisit your code while drafting to improve decision-making.
Full Summary
Writing detailed commit descriptions has been a beneficial practice for software engineers, particularly before the rise of AI tools. By spending five to ten minutes drafting these descriptions, engineers can provide comprehensive information that prevents others from searching through multiple sources.
The descriptions typically cover both the 'what'—the changes made—and the 'why'—the rationale behind those changes. Writing in the first person can make the message more relatable and easier to understand.
This reflective writing process encourages engineers to revisit their code, often leading to re-evaluation and potential improvements in their decisions. Overall, this method fosters better communication and understanding within development teams.
