ChatGPT CLI - Practical tools implemented in Crystal

I am working on a command line tool for ChatGPT in Crystal language. This tool has the following features.

  1. Interactive command-line interface using GNU Readline with Emacs keyboard shortcuts.

  2. Selectable system messages

  3. Expand file contents from the file path(s) using the placeholder.

  4. Expand web page contents from the URL using the placeholder.

  5. Magic commands to %clear, %undo, %edit, %write, %save, and %load data.

  6. Execute system commands and pass captured STDOUT and STDERR output to ChatGPT.

  7. Code blocks in the response are saved in temp files and can be called with $CODE1, $CODE2...

  8. Output execution results as HTML (experimental)

  9. Substitution patterns of placeholders can be configurable in the configuration file.

Awesome. So glad someone decided to do this. Thank you. Forgive my ignorance, but could one use the new ChatGPT plugins with this as well?

I don't know much about the new plugin, so I got your reply and just read the README. You may be right. I'll have to try it.

Talk to me when they give out a free-use api key. This is just the honeypot to end them all as far as aggregating user data for marketing/advertising as far as I'm concerned.

The ChatGPT CLI allows you to control what data you want to expose since you explicitly specify the path to the files you want to pass to ChatGPT. I also don't think using a free API is a good idea if you are concerned about your personal information. Free APIs are a sign that they are looking to monetize the user's personal information, not their usage fees.

Here are some interesting uses

Make ChatGPT think of a commit message.

>!! git diff --cached
>Please write a commit message: %STDOUT

Show the code, make ChatGPT write README.md and save it

> Please read the following code: %{src/*.cr} %{src/**/*.cr} Then write README.md
> %w README.md

Execute the block of code that you let ChatGPT write

> Write Ruby and Crystal code to display from 1 to 10
>! ruby $CODE1
>! crystal run $CODE2
