turbocommit is a CLI tool written in Rust that generates commit messages in accordance with the Conventional Commits specification. It uses the git diff to create commit messages that accurately reflect the changes made to a repository.
turbocommit can be easily installed with Cargo, Rust's package manager. Simply run the following command:
cargo install turbocommitPlease note that in order to use turbocommit, you will need to set the OPENAI_API_KEY environment variable. This API key is required to use the OpenAI gpt-3.5-turbo16k language model, which is used by turbocommit to generate commit messages.
When you have staged some changes, you can run the turbocommit (I recommend making a tc symlink)
| Short | Long | Description | Default |
|---|---|---|---|
| -n | Number of choices to generate | 1 | |
| -m | --model | Model to use | gpt-4o-mini |
| -d | --dry-run | Dry run. Will not ask AI for completions | |
| -p | --print-once | Will not print tokens as they are generated | |
| -t | Temperature (t |0.0 < t < 2.0|) | 1.0 | |
| -f | Frequency penalty (f |-2.0 < f < 2.0|) | 0.0 |
Please look at the help turbocommit --help for the most up-to-date list of models.
In some cases, the git diff for staged changes may be too long to fit within the 16384 (or 4096) token limit enforced by the language model, which turbocommit uses to generate commit messages. When this happens, turbocommit will prompt you with a message indicating that the git diff is too long.
To address this, turbocommit provides a list of all staged files and ask you to select any number of them. The tool will then generate a new git diff that includes only the changes from the selected files. If the resulting git diff plus the system prompt is still too long, turbocommit will repeat the process until the git diff is short enough to be processed by the AI model.
This allows you to generate conventional commit messages with turbocommit while ensuring that the git diff is short enough to be processed by the AI model.
To get help with using turbocommit, you can use the -h or --help option
$ turbocommit --helpThis will display the help message with information on how to use the tool.
