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
