🍱

bento is a CLI tool that uses OpenAI's API to assist with everyday tasks. It is especially useful for suggesting Git branch names, commit messages, and translating text.

Features

• Uses OpenAI's API to assist with tasks.
• Easy-to-use commands: -branch, -commit, -translate.
• Supports multi mode and single mode:
  • Single Mode: Sends one request to the API. Used for -branch and -commit.
  • Multi Mode: Sends multiple requests to the API. Used for -translate.

Name Origin of "bento" 🍱

The name "bento" stands for Benri Translator and Optimizer. The word "benri" is Japanese for "convenient," which reflects the tool's purpose to provide handy solutions and optimizations.

In Japanese, "bento" refers to a lunch box that contains a variety of different dishes. This analogy is perfect for our tool because it combines multiple functionalities into one compact tool, much like a bento box 🍱 that offers a variety of foods in one compact container. Thus, our "bento" tool is designed to be a versatile and efficient assistant in your workflow, packing numerous features in an organized manner.

Installation

It is recommended that you use the binaries available on GitHub Releases. It is advisable to download and use the latest version.

If you have a Go language development environment set up, you can also compile and install the 'bento' tools on your own.

go install github.com/catatsuy/bento@latest

To build and modify the 'bento' tools for development purposes, you can use the make command.

make

If you use the make command to build and install the 'bento' tool, the output of the bento -version command will be the git commit ID of the current version.

Additional Information

• API Token: The API token is passed via the environment variable OPENAI_API_KEY.
• Customization: To customize, use -multi or -single and provide a custom prompt with -prompt.
• Default Model: The default model is gpt-3.5-turbo, but you can change it with the -model option.
• Translation: The -translate command translates to English by default; use -language to specify the target language.
• File Handling: To work with files, provide the filename with -file or use standard input.

Using -branch and -commit

• -branch: Use this when you haven't created a branch yet. It suggests a branch name based on the current Git diff.
  • Large new files can be problematic for the API to handle. By default, Git diff excludes new files, which is convenient. If necessary, add new files with git add -N.
• -commit: Use this when you are ready to commit. It suggests a commit message based on the staged files.
  • If new files cause large diffs, generate the commit message before staging them to avoid exceeding API limits.

Here is an example of setting up bento as a Git alias on ~/.gitconfig. This allows you to generate branch names and commit messages from Git diffs automatically.

[alias]
sb = !git diff -w | bento -branch -model "gpt-4o"
sc = !git diff -w --staged | bento -commit -model "gpt-4o"

To show new files in git diff, use the git add -N command. This stages the new files without adding content.

git add -N .

Using -translate

The -translate option allows you to translate text to a target language. You can specify the target language using the -language option. By default, the target language is English (en).

Translating Text from a File

To translate text from a file named example.txt to Japanese, use the following command:

bento -translate -file example.txt -language ja

Translating Text from Standard Input

To translate text from standard input to French, use the following command.

echo 'hello' | bento -translate -language fr

Using Multi Mode with -multi

To proofread a text and correct obvious errors while maintaining the original meaning and tone, use the following command:

bento -file textfile.txt -multi -prompt "Please correct only the obvious errors in the following text while maintaining the original meaning and tone as much as possible:\n\n"

Using Single Mode with -single

The -single option is used when you need to send a single request to the API. This is useful for tasks that must be processed as a whole.

To summarize text from a file named example.txt, use the following command:

bento -single -prompt 'Please summarize the following text:\n\n' -file example.txt

Tips

• Prompt Tips: When using -branch, the default prompt is: Generate a branch name directly from the provided source code differences without any additional text or formatting:. If you provide a custom prompt, it is recommended to add "without any additional text or formatting" at the end for better results.
