Setup

1. Install

   pnpm add -g @hirotomoyamada/ai-commit

2. Obtain your API key from OpenAI.

3. Set your API key in ai-commit.

   ai-commit config set apiKey=<your token>

Upgrading

To check the installed version, run the following:

ai-commit --version

To install the latest version, run the following:

pnpm up -g @hirotomoyamada/ai-commit --latest

Usage

To generate a commit message, run the following:

ai-commit

Tip

ai-commit provides a shortened alias aic.

When you run ai-commit, two scenarios may occur:

1. If there are files staged:

   • AI detects the differences in the staged files and generates a commit message.
   • Once you review and approve the generated commit message, it will be committed.

2. If there are changed files not yet staged:

   • A list of changed files will be displayed.
   • You select the files to add to the stage from the list.
   • AI detects the differences in the newly staged files and generates a commit message.
   • Once you review and approve the generated commit message, it will be committed.

Tip

To add all changed files not currently staged to the stage (with git add .), set the --all or -a option.

Changing the Commit Message Suggestions

To change the commit message suggestions, set the --generate <i> or -g <i> option. The default is set to 1.

ai-commit --generate 5

Note

You can set up to a maximum of 5 suggestions.

Applying Conventional Commits

Many projects have rules for commit messages based on Conventional Commits. If you want to apply these rules, set conventional with the --type or -t option.

ai-commit --type conventional

Note

By setting it in the configuration, you can always apply the Conventional Commits commit message rules.

Configuration

To get the configuration, run the following:

ai-commit config get

To get specific items only, run the following:

ai-commit config get generate locale

To set values in the configuration, run the following:

ai-commit config set generate=5 type=conventional

To reset the configuration values, run the following:

ai-commit config reset
