Automated Commit Messages and Flow State

I recently came across OpenCommit, which claims to “generate commit messages with an LLM in 1 sec”. Here’s what’s good:

• Helps maintain flow state - you can fire-and-forget and the messages are about as accurate as they’d be if a human wrote them
• Available on the command line, just oco
• Works reasonably well with local models running via ollama serve
• MIT Licensed

Regarding “flow”, pay attention the next time you write a commit message. Do you feel the context switch happening as you go from “doing” to “documenting”? I do, and I have aversion to that feeling.

My Setup

1. Install OpenCommit using their instructions.
2. Install Ollama using their instructions.
3. ollama pull mistral
4. ollama serve
5. Create ~/opencommit file:

OCO_GITPUSH=false
OCO_MODEL=mistral
OCO_API_URL=http://127.0.0.1:11434/api/chat
OCO_API_KEY=undefined
OCO_AI_PROVIDER=ollama
OCO_TOKENS_MAX_INPUT=40960
OCO_TOKENS_MAX_OUTPUT=4096
OCO_DESCRIPTION=false
OCO_EMOJI=false
OCO_LANGUAGE=en
OCO_MESSAGE_TEMPLATE_PLACEHOLDER=$msg
OCO_PROMPT_MODULE=conventional-commit
OCO_ONE_LINE_COMMIT=false
OCO_TEST_MOCK_TYPE=commit-message
OCO_WHY=false

Usage

• (optional) git add <file>
• oco

Some Weird Fails:

llama3.2:1b

Seems to want to put the filename into the commit message. Includes responses to the prompt that could probably be engineered out, but I don’t want to bother.

fix(mouse support.md): add mouse support for tmux
feat(mouse support.md): enable mouse navigation in tmux terminal

Note: I've kept the commit message concise and focused on the changes made. Since there's no explanation provided, I've omitted it. If you'd like to include a brief description of what was fixed or added, please let me know!

gemma:2b

When asked to commit a markdown file in a hugo repository without any TypeScript code in sight, we get this commit message, which is absurdly irrelevant and really tells how how ingrained front-end development is in these coder models.

This commit fixes the case of the port variable in the server.ts file by changing it from a lowercase port to an uppercase PORT. This change improves the readability and maintainability of the code.

This commit also adds support for the `process.env.PORT` environment variable to the server.ts file. This allows the server to be run on a configurable port, which can be set by the user. This change makes it easier for users to run the server on a port of their choice.

I did a s/berreft/bereft and got this message:

fix(tmux mouse support.md): correct typo in "berefft" to "barefoot"
