complish

English | 简体中文

Generate auto-completion file for any CLI via chatGPT.

Complish is a tool to generate completion file for any type of CLI, now supports zsh and fish.

The tool uses chatGPT API to parse the help page of a CLI (the text printed when executing cmd --help) and output structured information about the help page. And then generate a completion script for specific shell like zsh or fish.

Installing

npm i -g complish

Usage

complish [options] [cmd]

API key of OpenAI is necessary, and you can set the key either by setting an environment variable or using complish set-key like following:

export OPENAI_API_KEY=your_openai_api_key

or

complish set-key your_openai_api_key

If you have no the key, you can apply for one on OpenAI and remember to keep secret!

Example in fish

Generate a fish completion for a CLI named mycmd

complish mycmd --shell fish

And you will find mycmd.fish in your current directory when the script finished.

Note that the execution speed is limited by the response time of ChatGPT, so it may take 10 seconds to 1 minute or more to generate a completion file.

Then copy the fish script to the completions directory of fish shell for which the file can be automatically loaded. Other available fish completion directories can be seen here

cp ./croc.fish ~/.config/fish/completions/

It will work after you reopen the terminal and you will find the completion works when you press <TAB>

Example in zsh

Generate a zsh completion for a CLI named mycmd

complish mycmd --shell zsh

And you will find _mycmd file which is the format of zsh-completion file in your current directory when the script finished.

Then copy the zsh completion file to a directory that is in environment variable $fpath. You can check it by running echo $fpath for all valid directories in zsh.

cp ./_mycmd /Users/you/.zsh/functions

It will work after you reopen the terminal and you will find the completion works when you press <TAB>
